WHEELS, BRAKES & TIRESABOUT YOUR HITCH
LOCK’N’ROLL HITCH
The OP4 comes as standard with a Lock’n’Roll arculang hitch. The hitch allows for pivong on 3 axis and provides an overall
smoother towing experience. Ensure the locking pin is fully inserted and secured in place before towing. When hitching the OPUS®
to your towing vehicle you must ensure that someone is close to the handbrake in order to maintain control of the trailer, parcular-
ly when unhitching on uneven ground or a slope. The Lock’n’roll hitch is a two-part hitch with a vehicle-side and a driver side part.
• The vehicle side ts in a 2’’ hitch receiver and should be locked in place with an appropriate hitch receiver lock.
• The trailer side is already installed on your OP4.
• To connect the two parts, the trailer side pin arms should be placed in the receiving secon on the vehicle side part.
• The hook arms then t over the trailer-side pin arms and a securing pin is ed through the holes in the hook arms and the hole in
the main receiving secon on the vehicle side part.
• This will hold the trailer side pin arms in place.
• Use a locking pin on the securing pin to fully lock the coupling in place.

ABOUT YOUR ELECTRICAL PLUG
The OPUS® is ed with a 7-pin at plug that connects all the exterior trailer running/break/turn
lights and the electric brakes to the towing vehicle. You will require a 7-pin connecon on your
tow-vehicle as well as an in-car electric break controller installed in your tow vehicle to operate
them.
ABOUT YOUR BRAKES
The OPUS® is ed with electric trailer brakes. You need an electric brake controller ed to your car in
order to tow the OPUS® and operate the electric breaks safely. Failure to tow with a brake controller
in your vehicle is both dangerous and illegal. You can tell if your brakes are working properly by
connecng the 7-pin plug, starng the engine of the tow vehicle and then geng someone to listen
to the brake hub whilst another person applies the brakes in the tow vehicle. If they are working
correctly you will here a low humming sound as the brakes are applied.
BRAKE MAINTENANCE
As part of the annual service check that you should have completed by an accredited industry service
agent, the brakes must be checked and maintained.
INSTALLING YOUR SAFETY CHAINS
The OPUS® is ed with 2 safety chains on the tongue. One end of the chain is ed to the OPUS®
chassis and the other end has an aachment clip which should be aached securely to your tow
vehicle bumper or receiver.
TOWING
The driver of the tow vehicle must ensure that their Driver’s License is valid for towing the OPUS® Camper. It is highly
recommended, parcularly if you are not experienced in towing, that you adhere to any applicable laws for the state in
which you are driving. Many guides are available from leading associaons and should be studied before you embark. Trailer
towing laws are dierent in each state. Please be aware If you are traveling across mulple states that you could suddenly be
breaking tow laws if you’re not careful. States dier on their rules about mulple trailers. If you’re hauling a camper and a Jet
Ski behind it, you’d be OK in South Carolina, but breaking the law once you cross the Georgia state line. No maer where you
are in the U.S., the following features are recommended safety equipment for trailer towing:
* Lights: Your trailer lights must be maintained in working order for basic road safety.
* License plate light: Make sure to clearly display your license plate
* Reectors: These are an invaluable precauon to keep your large trailer visible.
* Flares: Keep these at hand to clear o a secon of the road aer an accident.
* Tie-downs: If you are loading anything on a trailer that could possibly fall o, you’ll need e-downs to secure it at
mulple angles.
• Ensure the clips on the hooks are in place to fully secure the hooks.
• Do not aach the hooks to the hitch itself.
• Ensure that you have enough slack in the chains to turn your vehicle adequately.
• Should you require less slack, the chains can be twisted or crossed below the tongue before
connecng to your vehicle to ensure the chains do not drag on the ground.

CONTROL PANEL QUICK TIPS
• The Volt Meter – Measures the current baery voltage output. Most appliances will require at least 12.2v from the
baeries otherwise they will not work.
• Amp Meter – This shows how many Amps you are currently using. The OPUS® has 2 x 100ah AGM baeries. This gives
you 100 usable amps for o-site power.
• Baery Indicator – This shows the total capacity remaining in your baeries. If you are showing 50% on your baery
meter then your baeries will not put out the 12.2v required for most accessories to operate.
• Ensuring you keep a close eye on all 3 gauges will help to make sure you are fully informed on the current performance
of your 12v baery powered electrical system.
VOLTAGE METER
• The Upper Number shows what Voltage (power level) the baeries are currently reading. It is the strength of the cur-
rent owing from the baeries.
• If this number were to drop beneath 12.0v with no load (i.e. no accessories running on the OPUS®) then it is highly like-
ly all the appliances inside your camper would stop working as the baeries are not able to put out enough voltage to
keep these appliances running.
• Do not take a reading when an appliance, such as a fridge, is running. It will give a false reading. Voltage may appear
below 12.0 if the baeries are under load (fridge is acvely running).
• The lower number shows the quanty of energy you are currently ulizing from the baeries.
• If you imagine a water tank holding 100gallons and you drain 4 gallons an hour (gallons would
represent amps), then you can tell how quickly under current usage condions your baeries will
be fully drained.
• Remember your appliances all cycle at dierent rates so this number becomes very important for
esmang baery life.
We strongly recommend you review the OPUS® O-Road User Manual thoroughly before seng up you OPUS® O-Road
Camper for the rst me.

SETTING UP YOUR OPUS
Step 4 - Set up the exterior
• Whilst the tent is inang, level and stabilize the trailer. Fold down the stabilizer leg using two hands; one to pull out
the blue handle and the other to support the weight of the leg into the vercal posion. This helps prevent damage to
the locking pins.
• Use the included corner steady winder or 3/4’’ hex socket cordless drill/driver aachment, wind down each corner
steady leg unl it touches the ground.
• Depending on the terrain, you may need to adjust each corner to level the OPUS® to achieve a good level.
• While your tent is inang you can use this me to set up your kitchen. See page 20 for more instrucons.
Step 6 - Set up your interior
• Use the triangle-end key to turn your door latches and open the door. Take care to hold the weight of the door as you
fold it down to prevent it swinging down and causing injury. Adjust the height of the steps as required by unhooking
the pins, sliding the legs out and replacing the pins.
• Turn the lights on via the control panel. The foot-well lights are controlled by the dimmable light switch on inside
on the right of the door. Connect the interior ceiling lights into the 12v mini outlet. The ceiling lights are controlled
individually via switches on their lines. The exterior wall light by the kitchen is controlled by the toggle switch next to
the dimmable light switch.
• Set up your sofa. Start with the center-back cushion, followed by the corner back cushions, then the side-back
cushions. Fold out the legs of the table. Adjust the height of the table by pulling out the pins and extending the legs.
Step 1 - Prepare to deploy your camper
• Once you have posioned your OPUS® in the desired locaon, engage the handbrake.
• Raise or lower the tongue jack wheel to level your OPUS® length ways.
• Remove all items from the Cargo Rack. Un-clip the securing latches on the passengers side. On the drivers side remove
locking pins and unfold the Cargo Rack and secure the locking pins back in place.
• Un-clip the spare wheel carrier and swing it down to the horizontal posion, taking care to support the weight of the
spare wheel carrier so that it does not swing free and fall whilst out of control.
Step 2 - Open the Bed Lids
• Open the front lid through 180°. Gas struts are ed to support the weight of the lid at this stage. Secure the front lid
to the stone guard frame with the latch and secure with the retaining pin.
• Repeat the process with the rear lid and fold out the two rear support legs. Secure the legs into place by inserng the
D-pin clips through the aligned holes in the lid and locking the clip.
• At this stage walk around the OPUS® and inspect the tent to ensure that the canvas is properly located within the
aluminum channels and that no part of the tent is caught or snagged. Fit each corner of the canvas over the corner of
each bed tray. The seam on the canvas should line up with each corner of the bed lid.
Step 3 - Inate your tent
• Ensure all ve of your quick release valves on the driver’s side are closed.
• Open the control panel door and if not already connected, insert and turn the red turn-key to power-on your OPUS.
• Press the Air Inaon buon on your control panel to acvate your compressor.
• Wait for the tent to inate to its full height before entering the camper. The compressor may sll be running aer
the tent has extended to its full height; this is normal and is simply the compressor increasing the PSI to the required
seng to make the Air Poles appropriately inated. Once the correct air pressure is achieved the compressor will shut
o automacally. There is no need to press the buon again.
IMPORTANT: Do not set up the interior of the camper unl the tent has inated to its full height. This can be
idened by the visual ‘popping-up’ movement of the camper and by the straightening of the air poles. For informaon on seng up your water system, propane system, kitchen, accessories and electrical
system please see the relevant chapters of this manual.

PACKING DOWN YOUR OPUS
Step 1 - Pack down the interior
• Aer stowing your personal items, close all both layers of all windows, making sure no water, dirt or debris is trapped
between the layers.
• Ensure maresses are secure using the straps provided
• Remove LED lights from the 12v mini sockets
• Tear down the sofa and fold away the table; stow the back cushions and table as shown in the below picture to
opmize foot well storage space for other items and to ensure your table and cushions are stowed to prevent damage.
Step 2 - Deate the tent
• Ensure that all users are outside of the tent and zip the front door closed.
• Open all 5 quick release valves, located externally on the oside of the
camper on each of the vercal air poles. Make sure you release the valves
using the middle ring as shown in the image. Allow the tent to deate.
SET-UP TIPS
• Ensure all ve of your quick release valves are closed prior to inang your camper.
• While inang, check that the OPUS® is stable and level prior to opening the two lids.
• IMPORTANT: Do not place or load anything on top of the tent whilst it is inang.
• IMPORTANT: Ensure children or frail adults maintain a distance of 5 from the air poles whilst it is inang.
• Should you need to switch o the compressor for any reason whilst the tent is inang, this should be done using the
main power switch. Please note that the Air OPUS switch is not a 2-way on/o switch (meaning that pressing this twice
will not turn the compressor o).
Step 3 - Fold away the bed-lids
• Li the canvas o of the bed-end corners and fold the tent inside the seals of the trailer. Try to fold the tent into the
main body of camper as much as possible; this will help to make closing the camper easier.
• Retract the steps and fold up and latch the door.
• Disconnect the bed-end supports and latches and fold over rst the rear lid, then the front lid. Do not try to latch down
the bed lids yet
• Walk around the camper to make sure that all of the tent is folded away within the seals. Pull more of the tent away
from the bed-end hinges and into the main body of the camper. Make sure that no part of the tent is trapped outside
of the hinge seals.
• Push the bed lids down to allow air to escape. Twist open the triangle bolt latches to the maximum and push down on
the bed lid so that the latches are over the hook. Do not try to close the latches unl you have done this for each latch;
the easiest and most ecient way to close the bed lids is to do it gradually.
• Push down on the bed lids enough to allow you to close the latches closest to the hinges rst. IMPORTANT! Do not use
the latches as a lever to close the bed lid as this may cause damage to the camper and is not covered under warranty.
Once you have closed the latches at the maximum extension of the triangle bolts, move around the trailer and ghten
each latch. Each latch should be checked for a ght t several mes as ghtening one can loosen others. Make sure
that no tent is outside of the seal.
• Fold away your bed-leg supports, hot water shower arm (if required) and then fold up your spare re carrier. Ensure
bolt spring bolts are locked in place fully.
Step 4 - Stow your Kitchen
• Disconnect your water & gas quick connects from the kitchen as well as the 12v kitchen light.
• Ensure the water hoses are stowed in the drawer and that the drawers are closed on the catches properly. Stow the gas
and waste water hose up through the aperture in the kitchen.
• Stow your kitchen support leg using the push-buon retaining pin under the kitchen.
• Slide the kitchen back inside the camper and lock in place using both spring bolts. Close and Lock the kitchen storage
door. IMPORTANT! Do not stow your kitchen whilst hot.
Step 5 - Prepare for travel
• Fold over your cargo rack and secure with the latches. Twist down the triangle bolts to ensure a secure latch and secure
the closed latch with the safety pin.
• Retract and fold up your stabilizer legs.
• Ensure all compartments are properly latched and locked.
• Connect to your tow vehicle making sure you lock the lock’n’roll securing pin in place using the locking pin and ensure
the vehicle side of your hitch is properly secure and locked to your tow vehicle.
• Retract your tongue jack wheel and hold up. Connect your safety chains, breakaway cable and
7-pin to your vehicle and complete your pre-trip checks to make sure your connecon is sound.

ABOUT YOUR AIR TENT
TROUBLESHOOTING AIR TENT ISSUES
Inaon issues
• Make sure all of ve quick release valves are properly closed.
• Make sure there are no extreme folds or kinks in the air beams (parcularly the main air beam where the AIR compressor
hose connects to) that could prevent air being transferred to the other air beams. The compressor will be able to
overcome most folds but in some cases you may need to make a minor adjustment to the tent to allow air through more
extreme folds that could be trapping air. If this happens, gently push on the middle air pole from the outside to help it
straighten and allow the pole to inate.
• Make sure all of the isolaon valves are in the OPEN posion otherwise AIR cannot pass between beams.
• Make sure your AIR Compressor hose is securely in the AIR tent inlet valve
• Should you experience issues with your compressor, you can use the included manual pump to inate your tent. This will
take around 5 minutes.
Deaon Issues
• We recommend opening each quick release valve and re-closing it in case you have cross-threaded the valve.
• Ensure you are removing the AIR compressor hose and capping the valve once you are inated.
• If you suspect an AIR leak, use the isolaon valves to close o each air beam so that you can idenfy which leak the beam
is on. Take care not to over-ghten the isolaon valves as this can damage the valve and in itself cause a leak. Remember
to open up the valve again when you need to re-inate your tent.
Should you idenfy a leak in your air beam or valve, please use the following map and contact OPUS HQ for a replacement
beam. For eld repairs, you can use the patch kit included with your OP4. We also recommend keeping the isolaon valves
closed unl the air beam is replaced to help prevent tent collapse. For instrucons on replacing the beam, please see the AIR
beam replacement secon of this user manual under Care & Maintenance.
AIR TENT DESIGN
Your OP4 AIR tent is made of 9 connected AIR beams in the main tent (and 9 beams in the annex if you choose that addion).
The tent is inated by the compressor that is mounted in the cabinet to the right of the door. The hose from the AIR compressor
is threaded up through the cabinetry to the main AIR tent inlet valve. The compressor is acvated by the buon on the
control panel, which also has a breaker switch should this be required. The air compressor is preset to the opmum pressure
of 6.5psi and will automacally shut o when the pressure in the AIR tent reaches this pressure. Occasionally you may wish
to adjust the psi to account for variaons in outside air pressure (caused by altude, temperature and extreme wind). Our
recommendaon is to rst check the suitability of the air poles at the preset pressure. If you then decide you require more or
less pressure in the tubes the psi may be adjusted using the dial located on top of your compressor. Turn the dial to increase
or decrease the pressure as desired, however you must not increase the pressure over 9psi and we recommend returning the
pump back to 6.5 psi for normal camping.
Once your AIR tent is fully inated and the compressor shuts o, please remove the hose from the valve and cap the valve.
This will stop any air leaking out around the compressor hose. Failure to remove the hose and cap the valve may result in
tent deaon.
Each Air Beam is connected to the beams next to it by an AIR transfer hose which has an isolaon valve on each end where
it connects to the AIR beam. Each AIR transfer hose has a spring inside it to protect it from kinks and bends that could
damage the hose or prevent air passing between the beams. We recommend regular inspecon of the AIR transfer hoses
and isolaon valves to ensure they are in good condion. You can nd the AIR Transfer hoses by zipping open the semi-circle
zippers in the roof of your tent. Should you need to close o the valve, the back secon is turnable. There are markings on the
valve to show which direcon to turn for open and close. IMPORTANT! If you close o a valve, please remember to re-open
it before trying to re-inate your tent to ensure air can reach each AIR beam.
The AIR Beams are housed inside
two protecve layers; an inner thick
protecve layer and an outer layer
built into the main tent. You should
aim to keep the AIR beams enclosed
inside the layers unless you suspect
an issue with the air beam. Should you
need to access the AIR beam, ensure
that no part of the AIR beam is caught
in the zip when you close it back up.

SLIDE-OUT KITCHEN
SETTING UP YOUR KITCHEN
Your OP4 kitchen is located on the door-side of the trailer in a slide-
out compartment. The compartment is secured with lockable push-
buon latches. The kitchen slide-out is held in place with spring-bolt
locking pins. To open up the kitchen, pull the spring bolts in and turn
them so they catch and stay open then slide the kitchen out to its
full extension. You can then access the kitchen side quick connects for
your gas and water connecons (please see the kitchen sink and Gas
system secons of this user manual)
OP4 KITCHEN FEATURES:
Kitchen Sink: please see the water system secon for informaon on seng up your kitchen sink with water.
Kitchen Stove : please see the propane system secon for informaon on seng up your kitchen stove with propane and use.
Slide-Out Surface: The kitchen has an addional slide out surface tucked under the stove. We recommend placing only lighter
items such as oven mis or cooking utensils on this slide out
Stove Wind Protectors: The stove has two wind protectors that fold out to each side of the stove and secure in place with pins
that slot into a hole on the kitchen surface. See the Propane Gas System for details on lighng the stove.
Dish/ Spice Rack: fold this up to vercal and set the rubber stand foot on the kitchen surface for stability.
LED Light: Posion the exible light to the desired posion. Plug the power cord for this light into the small 12v socket on the
exterior of the OP4. Ensure that the *Lights* switch is turned on so that the socket is receiving power. Be sure to disconnect
the light from the outlet BEFORE sliding away your kitchen.
Support legs: Folded underneath the slide out kitchen is a swing-down support leg. Push the buon catch to release the leg.
You can adjust the height of the leg as appropriate by loosening the wing nut pins to release the telescoping leg and then
ghtening them to hold it in place. To fold the leg away, retract the extendable leg fully and push the black end of the buon
catch to re-secure. There is also a secondary removable support leg pole which has a groove in the top that the underside of
the kitchen ts into. This pole is also adjustable. We recommend using these support legs each me you set up the kitchen.
WARNINGS
WARNING! Ensure the spring-bolt locking pins are locked in place AND that
the pushbuon locks on the door of the compartment are correctly closed and
locked prior to travel. Failure to do so could result in serious injury and damage.
WARNING! Please make sure the spring-bolt locking pins are in the extended
posion at all mes when the kitchen is set up so that the spring is not
compressed. Failure to do so could result in serious injury. Take care to compress
the locking pins again when closing the kitchen.
WARNING! Please ensure that all cords and hoses are disconnected and
retracted prior to closing your kitchen to avoid damage.
IMPORTANT! Do not posion the light over the stove. Always make sure that
the power cord is removed from the outlet BEFORE sliding the kitchen away for

• We recommend reading the manufacturer’s user manual that comes with your fridge in full to understand how this
appliance works and to assist in troubleshoong should this be required. We have also compiled a few quick ps that
are OPUS-specic:
• Your Fridge can be run on either 120v or 12v however we have designed the OP4 so that only 12v is supplied to the
fridge compartment to enable the most energy ecient usage.
• The Fridge appliance is energy ecient and works well with minimum amperage draw. Please ensure that your fridge
is set to ‘low’ or eco-mode to ensure you get the most ecient use and least impact on your 12v power consumpon
• We recommend turning your fridge on and allowing it to come down to temperature 24 hrs before your trip and whilst
connected to shore power as this is the me when your fridge will need to use the most energy
• You can leave the fridge turned on when you are traveling; simply ensure it is plugged in to the 12v socket in the storage
compartment and that the fridge switch on the main control panel is turned on.
• Your fridge compartment is ed with a fan-vent to help keep the temperature down in the compartment and so
reduce the power consumpon of the fridge. On hot days, you can also open the fridge compartment door but we
recommend keeping the fridge inside the compartment when not in use to keep it shaded from the sun.

ELECTRICAL SYSTEM
120V SHORE POWER - SAFE OPERATING PROCEDURES
The OPUS® comes ed with a 120 volt power system. This 120 Volt power system complies with NFPA and NEC
regulaons.
• The main circuit breaker and panel is located inside the OPUS in the oor well. Always
ensure you have clear access to the panel and it is not blocked at any me.
• The exterior shore power hookup is located on the driver’s side on the main body of
your OP4. With your OP4 we supply a 30ah shore power cable and yellow dog-bone
connecon for both campsite and home outlet connecon. The power cable connects
directly to the side of your OPUS. The dog-bone can be used to adapt the cable to plug
in to your 3-pin socket at home.
• This shore power connecon will provide your OPUS with 120v power to the two 3-pin
sockets in your OPUS and provide power to your NOCO baery charger to charge your
baeries.
• Take care to ensure proper maintenance of the power cord and pigtail accessory items.
Always use a Listed and approved 30ah cable and adapter and a grounded power
source. Never use an extension cord.
• DANGER! Due to potenal danger in failing to heed this warning, the recreaonal
vehicle manufacturer cannot be held responsible should damage, injury or death result
from failure to connect the power cord to a properly grounded power source.
OP4 internal 120v power points:
1. In the long bench storage compartment directly opposite the door. This socket should have your NOCO baery charger
plugged in and is designed to supply the baery.
2. In the storage compartment to the right of the main door.
3. In the storage compartment behind the seang area next to the front bed.
12 VOLT - SAFE OPERATING PROCEDURES
The OP4 has two 100ah deep cycle marine baeries installed as well as a fully automac baery charge controller. You
will need to charge your baeries for at least 24hrs prior to each trip using a 120v shore power connecon to ensure that
they are fully charged. The main control panel has a baery volt-meter that will provide an indicaon of the charge level
of your baeries. A fully charged baery bank will be indicated by a full baery symbol and the voltmeter reading around
13.7volts. If you are at a campsite with shore power then we recommend connecng for the duraon of your stay to keep
your baeries fully charged. If you are camping o-site without 120volt power then the length of me that your baeries
will last will depend on how much 12volt energy you use, the ’health’ or condion of your baeries and in some cases the
ambient temperature. Your control panel will show you how much power you are using and how much remaining power is
in your baeries to help you manage your power consumpon.
Your 12v system is controlled by the main control panel (as shown on page 12) which is located behind the exterior panel
to the le of the door. On the panel you will nd the main 12v switch (the big red key). There are separate switches for the
Front water tank pump, Rear water tank pump, lights, 12v sockets, Fridge and Heater (Oponal). To supply power to these
features, use the red main power key and turn the 12v power on your unit and choose the associated switch.
12V POWER - CONT.
The OP4® has many 12v outlets that are a combinaon of standard 12v sockets, mini 12v sockets and USB sockets. There are
also a range of 12v features included with the OPUS, all controlled by the main control panel, the locaons of which are listed
below. All switches have their own reseable breaker located above the switches.
Outlets
• The internal 12v sockets and external 12v socket will operate on 12v power from the leisure baery; heavy usage and
power-hungry appliances will deplete the baery’s charge quickly.
• Inside the OPUS® there are four 12v mini sockets. These are for the 12v LED light strips.
• There are two 12v outlets located a) by the main AIR hose inlet and b) inside the storage compartment behind the
seang area next to the front bed. There is also a 12v/ USB outlet to the le of the door.
• On the exterior, there is one 12v outlets on the main control panel and one by the slide-out kitchen. There are also two
addional 12v mini sockets and a standard 12v socket. The two mini sockets are designed to operate the 12v LED light
on the kitchen and a small annex light.
• In the front tool box / fridge compartment here is a standard 12v socket intended for use with the fridge. In the same
area there is a small switch that operates the fan located in the door (if ed on this model)
Lights
• In both exterior tool box/ fridge compartments there is an LED work light. This has an automac on/o photo sensor.
• Just inside the door by the 12v stereo there is a dimmer light switch that will control the interior foot well lights.
• There is also a rocker switch that controls the light for the exterior light mounted to the side of the OPUS by the kitchen.
Other 12v features
• There are two water tank gauges on the control panel which will display the water level when the ‘water’ buon is
pressed. For more informaon on your water tanks please see the water system secon.
• The OP4 features a 12v stereo/ CD player with two speakers in the foot well
• The trailer lights and electric breaks are wired to a standard 7 pin trailer plug. The OPUS® is ed with electric breaks
with need an in-car electric break controller installed to operate.
• The baery charger is fully automac and will recharge the leisure baery if the OPUS® is connected to an electric hook-
up. The baery will also charge whilst in transit if the tow vehicle has the 7-pin connecon.
BATTERY TIPS!
• The baery indicator on your control panel will show how much energy is le in your baery bank. It is important to note
that it does NOT explicitly show how much usable power is le in your baeries.
• You have a 200 amp baery system. AGM baeries are able to reliably put out over 12.0v of power for 50% of their
capacity. Most 12v appliances will require a 12volt output from the baeries to work. This means you 100 usable amp
hours from a fully charge set of baeries. The indicator on your control panel will show you how much total energy you
have in your enre baery bank. This means that when your indicator shows 50% you have used all of the usable power
within your baery bank. If you connue to drain power from your baeries beyond this point can and will most likely
cause damage to your baery bank.
• AGM baery lifespans are longer when they remain at full charge. Frequently discharging your baeries and leaving
them empty will accelerate the degradaon process of your baeries and reduce their lifespan. The NOCO Genius char-
ger installed in your OP4 will control the amount of charge delivered to your baeries so that they do not over charge,
therefore you can leave your OP4 plugged in at all mes when at home.
• If you are not keeping your OP4 plugged in whilst at home we recommend that you disconnect your baeries to maintain
good baery health. Please see the *care and maintenance secon for more informaon on this topic.
• The CO/LP alarm is wired directly to the baeries. This means that turning the power to the OP4
o on the control panel will NOT shut power o to the CO Alarm. Please follow the winterizaon
process for baery care to ensure you are fully disconnecng the baeries during long periods
of storage.
• Always set your fridge to ‘LOW’ before heading out on your trip. This will use less power from
your baery and allow you longer o-site camping.

4. Open up the main secon of your annex. Idenfy the zip & Velcro line which is how your will aach the annex to your
main tent and layout lay out your annex with the two front door secons furthest from the camper.
5. Our recommendaon is to then stand between the OPUS and the annex and start zipping at the door side, walking
backwards between the OPUS and the annex as you close the zip. This will assist in locang both the Cross Filling Tube
that you installed on the main OPUS tent as well as the receiving valve on the annex-side about half-way along the zip
line. The receiving valve is located on the central air pole of your annex.
6. Once located, connect the Cross Filling Tube to the receiving valve on the side of the annex. Take care to ensure that the
spring is inside the grey tube to help protect the hose from geng kinked. Install the tube to the receiving valve in the
same way as in step (2) except you will need to thread the top of the valve on to the Cross Filling Tube before you push
the tube on to the valve. Twist the top of the valve on, to secure the tube in place.
7. Open the valve on the annex-side. Finish zipping the annex to the side of the OPUS and fold the Velcro ap over the zip.
8. Ensure all 7 quick-release valves are closed on the annex and all 5 on your OPUS main tent then press the AIR compressor
buon on the control panel and wait for the annex to inate.
9. Keep an eye out for obstrucons and when the annex is starng to form, feel free to help guide the air beams to assist
in easy owof air through them and form nal annex structure.
10. Once your annex has inated, you may nd that the posion of the AIR poles needs adjusng so that the annex is fully
tensioned. There are black straps between the oor-ends of the beams on the main tent secon, which will help to
ensure the opmal placement of the beams. You can then peg the corners and guide ropes of the AIR annex to the
ground to secure your posion.
11. Lay your oponal ground sheet and aach this to the main tent using the zippers provided. There are zip-open secons
of your ground sheet to allow the kitchen and fridge to slide out. You can also then zip on your side walls.
12. Aach Velcro seals between canopy and annex
AIR OPUS® TIP: You may nd that the AIR annex is easier to shape with the side walls and front doors zipped closed, as this helps to create more structure
to prevent the annex poles from distorng by over-extension when inang.
AIR OPUS® TIP: If your annex takes longer than usual to inate check that your quick-release valves are all fully closed and that none of the AIR poles are
pinched, prevenng AIR moving through. If this happens, you can easily move the air pole to allow AIR ow through and allow the pole to inate.

CARE & MAINTENANCE
CARING FOR YOUR CANVAS
The tent and annex of your OPUS® are made from poly-coon, a canvas type material. This has many benets as it is breathable
and results in a cooler interior in warm/ hot weather and a warmer interior when in use in cooler weather condions. In order
for the OPUS® to give you years of camping pleasure, the tent secon needs to be cared for and MUST NOT be le wet/damp
when packed away. It is, of course unavoidable at mes that you will have to pack down your OPUS® when the canvas is
wet. It is very important that the OPUS® is opened up to dry o as soon as possible and should be done within 24 hours.
• Except for the supplied gas hob, do not use a gas appliance or open ame inside the OPUS® and do not subject the tent
to re.
• Maintain adequate venlaon in the camper at all mes, especially when sleeping.
• Allow condensaon to clear and dry before packing/storing the camper.
• Regularly check the seams of the tent and if required apply some seam sealer such as Kampa Seam Sealer or suitable
alternave. Follow the product instrucons and allow to fully dry before packing.
• Regularly check the Velcro straps and seams, along with the clips on the inner tents.
• Never force the zips of the tent to open or close; inspect for any issues and recfy as necessary.
• Ensure the zips are used and cared for properly, if needed a zip lubricant can be used to allow for smooth operaon.
• Regularly inspect the tent for holes, rips/tears and damages and have a suitable tent repair kit for use in emergencies.
• Take care when seng up and packing down the camper to ensure the tent, and the annex beading is not caught or
snagged, should this occur retrace the steps and retry making sure the issue is reced.
Should a rip/tear occur assess the damage before taking acon. If unsure contact us on 925 215 7315 for advice. Small rips/
tears can be repaired using the appropriate repair kit and procedure and may not require a professional or return to us for
repair; should the damage be signicant or exceed your capacity, please contact us.
• Clean the tent with warm water and a so sponge (without a scourer), this may require complete set up of the camper
(fully tensioning the tent) depending on the locaon/severity of the stain; allow the tent to completely dry before packing.
• Do not use washing up liquid, detergent or anything stronger as this could adversely aect the tent or result in some
damage.
• The tent is NOT machine washable.
• AVOID sharp objects near the tent canvas; sharp/pointed objects and poles should be stored on the oor away from the
tent to avoid damage.
• When the camper is packed, ensure nothing is scking out and a proper seal is achieved around the periphery and the
center (seal to seal contact).
• AVOID strain on the inner tents by loosening the aachment straps when necessary
WEATHERING
Your Air OPUS® tent has been manufactured using a polyester/coon fabric. Before a polyester/ coon canvas is used for
the rst me, it is important that the tent is weathered. Inate the Air tent following the inaon instrucons when rain is
expected. When the coon becomes wet for the rst me, the weave of the coon will close. There is no predetermined
me for weathering so please do not be surprised if there is leakage through the canvas and seams the rst few mes it rains.
• Your OPUS® Air tent is made from the best available materials. On rst examinaon, you may nd some slight variances
in color, thick threads, pigment stains and changes due to the weather and the environment. These are all normal and
will not aect the connuing performance of the product and are not faults or errors.
• When your Air OPUS® is not inated, the window material may pick up some impressions from zips, etc., this is quite
normal and some of these impressions will disappear over me but some may remain. This is not a fault.
• Please ensure your Air Tent is only packed away when completely dry. A wet/damp canvas will develop mildew/mold
very quickly and damage your canvas.
• The inside and outside of your tent can be cleaned but only with fresh clean water and a damp cloth.
UNDER NO CIRCUMSTANCES MUST DETERGENTS OR CHEMICAL CLEANERS BE USED AS THESE WILL
DAMAGE YOUR CANVAS.
You may also experience, depending on the weather and use, condensaon. This should not be confused with leakage.
To reduce the risks of condensaon, please ensure your product is adequately venlated. Please note that under certain
condions, all tents will suer from internal condensaon depending on atmospheric condions, the weather, the amount
of moisture in the air/ ground, evening and night me temperatures etc. Condensaon can be quite severe causing a lm of
water on the inside of your tent (roof and sides) which may drip onto items in your tent and in severe condions can leave
puddles of water.
Zips should be treated with care, use two hands when closing and opening and do not step on them during set up or take
down. Never force a zip. If a zip opening is ght it is more than likely because your tent is not aligned correctly. Candle wax
may be used to help a zip run more smoothly.
Please remember that your air tent is a temporary structure made from natural bers. Please note that in ber products
used in outdoor applicaons, product life may be lower because of aack from UV or acid rain. Discoloraon of the fabric
may be an early indicaon that your tent has been aacked. To limit damage by UV, where ever possible, please site your
air tent in a shaded area avoiding direct sunlight. Please be aware that connuous exposure is a more serious problem than
intermient exposure, since UV aack is dependent on the extent and degree of exposure. Fabrics can be weakened by
prolonged exposure to sunlight and use for extended periods in strong sunlight will soon cause deterioraon. UV degradaon
is not covered under the air tent’s warranty. The Warranty does not cover air tents used permanently or for display purposes.
WEATHERING OF SPECIAL THREADUSED FOR SEWING
Your OPUS® Air tent has been manufactured using a special sewing thread which expands and swells to close the holes made
when stching the product. The thread swells and expands when wet. It may take a few mes for the holes to completely
close.
ACCESSING AND REPLACINGAN AIR BEAM
If you suspect your AIR tent has a leak and you have tried 1) removing and capping the main AIR inlet valve and 2) opening
and re-closing your AIR quick-release valves, we recommend closing o your isolaon valves for each beam. These are located
behind the quarter-circle zips in the roof of your air tent. Twist the rear ring towards the “closed” posion as indicated on
the valve. The Air beam with the leak can be idened by a soening or complete deaon of the beam or a hissing sound
of air escaping.
If you are in the eld and can locate the source of the leak, you may be able to use the patch kit provided to patch the leak
as a short-term x in the same way that you would patch a bicycle re. When you return home, contact OPUS HQ or your
dealership and use the AIR Beam map in this manual to order your replacement AIR beam. All AIR beams and valves are
covered under warranty for two years.
In some cases, you may nd that simply by closing the isolaon valves your tent stops deang; this is an indicaon that the
issue is in the valve or transfer hose and air is escaping when the valve is open. You can make sure that the gray transfer hose
is correctly seated on the valve by unscrewing the front part of the valve that holds the gray hose in place. Push the gray
hose back over the valve and screw the front part of the valve back on. If this does not resolve the leak then it is likely that
the valve will need replacing. As the isolaon valves are integral to the AIR Beam, the whole beam will likely need replacing.
To inspect or replace an AIR Beam, follow the below instrucons to disconnect from the main tent. Depending on which
beam you are replacing and its locaon, you may nd it easier to keep your isolaon valves closed with your AIR tent inated
to replace the beam.
1. Ensure all LED lights are o & unplugged whilst replacing the AIR Beam and that 12v power is turned o and shore
power is disconnected. Carefully locate the faulty beam and deate it enough so that you can manipulate the beam.
Depending on the locaon of the beam, this may cause the tent to collapse parally which can cause a trip hazard if
you are working from inside the tent. We recommend having a second person help to hold the tent up and maintain
access to the exits.
2. Unzip the beam from the outer layer protecve layer and remove Velcro straps.
39
3. Disconnect the faulty beam from the AIR transfer hoses connecng it to the rest of the tent. Make sure the isolaon
valves are in the closed posion on both sides of the AIR transfer hose. Unscrew the front part of the isolaon valve unl
you can slide it along the gray hose. Pull the gray hose o of the valve. It is not screwed or glued in place, just a ght t.
Take care not to damage or stretch the gray hose and do not use tools to pry it o.
4. If the air beam you are replacing is 1T through 5T then you will need to disconnect the exterior quick release valve.
Unscrew the valve including the larger retaining nut at the back of the valve. This will allow you to push the rubber part
of the valve connected to the air beam through the main tent and disconnect it from the inner protecve layer.
5. You should now be able to remove the faulty AIR beam inside the inner protecve sheath. Please note that it may be held
in place by Velcro at the ends. You can now unzip this and remove it for inspecon and patching or replacing.
6. Next, take your repaired or replacement AIR Beam and insert it back into the inner protecve sheath. Take care to avoid
damaging the exposed rubber beam and do not catch the beam in the zip. Make sure there are no twists in the air beam
and that the valves properly t through the apertures in the sheath.
7. Re-insert the beam into the main tent. If the beam is 1T through 5T you can start by feeding the quick release valve back
through to the exterior of the tent and replace the retaining nut and valve.
8. Re-connect the AIR transfer hose on the main tent to the new beam. Push the gray transfer hose over the isolaon valve
on the new beam and screw the front part of the valve back in place on the valve. Please note that you may nd this part
on the isolaon valve on your new AIR beam too - of so, please retain this as a spare.
9. If you are sased the replacement AIR beam has been inserted correctly and the tube is fully inserted into the valve,
zip the new beam inside the outer protecve layers aached to the tent and replace the Velcro straps. Posion the ends
against the Velcro on the other beams or the interior furniture as required.
10. Open your isolaon valves on the new beam and on the connecng AIR beams. You should hear and see the new beam
ll with air quickly. Depending on which beam you are replacing, you may need to open the rest of the isolaon valves
and press the AIR compressor buon to fully inate the tent.
CUSTOMER’S RESPONSIBILITIES
In order to ensure you get the most out of your OP4 and that warranty claims may be processed in a swi and mely
manner, we ask that our customers adhere to the following guidelines:
1. Regular and proper maintenance of your OP4, including but not limited to the steps outlined in this user manual. If
you have maintenance or service quesons not covered by this manual OR you noce something out of the ordinary
with your camper please contact your dealership for more informaon This includes scheduled maintenance of
your OP4 and addressing any issues as they arise and without delay
2. Get to know your OP4 well. By learning about your camper and its components you will get an enhanced user
experience and avoid issues arising from mis-handling as well as become more likely to spot if something requires
addional servicing
3. It is the responsibility of the OP4 owner to ensure all warranty work is completed by an approved OPUS dealership.
Failure to do so may result in incomplete or refusal of warranty claim repair cost reimbursement.
Any modicaons without wrien consent from OPUS Camper could result in loss of warranty coverage. Contact us or
your dealer before compleng any work.
EXTERNAL CARE FOR YOUR OP4
• Closer and more thorough inspecon of your OPUS exterior will be required aer extended trips and a higher amount
of tough, o-road runs. Inspect the outside panels of your OPUS® including the roof (bed lids) for any damage, cracks
or wear. Proper maintenance of seals is necessary to keep moisture from entering and causing severe damage such as
rot, mold or mildew. If you nd missing, damaged, dry, cracked or weathered seals, reseal or replace as necessary by
contacng your purchasing dealership. Check with your dealer for the type of caulking required for and correct methods
of resealing or replacing.
• Inspect the sealant around the panels to verify that there is adequate bonding around the body panels and exterior
features such as the front storage box/fridge cabinet. This is especially important aer an impact/accident to the camper
to ensure the integrity of the body’s resistance to water ingress.
• Regularly check the seals (inner and perimeter) of the camper, to ensure there has been no damage. Ensure your OPUS®
is packed properly on level ground to seal the camper and prevent water ingress. Failure to properly maintain your seals
may be classed as neglect of maintenance and result in a decrease in coverage under your warranty
• Keep the body and the roof of the camper clean, it is best to clean any mud and dirt o the camper immediately aer
every journey to maintain its clean nish.
• Prolonged exposure to mud, dirt and salt may deteriorate the nish of the camper.
• Extended exposure to sunlight, air pollutants and excessive moisture can also negavely impact the nish of the camper.
We recommend regular washing and protecon during storage to maximize the lifespan of the nish.
• Inspect the condion of the frame, under-body, suspension and chassis regularly to keep it clean and address any damage
that may lead to rust. This is parcularly important to complete aer each tough o-roading run or when driving during
winter when road salts are in use. Always clean down your trailer fully if you have driven in snow, mud or wet condions
and is road salt use is suspected.
• The body of the camper can be washed with soap and water using a so sponge. Rinse the camper thoroughly aer
washing. A damp cloth may be preferred especially for small spots and dirt. Do not use a pressure washer as this can
damage the nish. Avoid spraying water into vents and seals.
• Specialist products such as ‘Waterless Wash and Shine’ products may be used where/when adequate water is not readily
available. Read and follow the instrucons carefully and it is advisable to try any product to be used on the camper on a
small inconspicuous spot to ensure/verify it is suitable before full use.
• Any form of damage or scratch to the paint work or nish of the camper on the body may be repaired or cleaned by using
a suitable ‘touch up’ sck/paint. Contact OPUS® camper directly for further informaon.
• If your camper has been vinyl wrapped to a custom color care must be taken to prevent peeling of the wrap if a scratch or
tear has occurred on the body panel.
