12 QUICK TIPS TO
SET UP AND PACK UP
YOUR Air OPUS®
12 Handy tips that will make you a
PRO at setting up an Air OPUS!
Invest in a cordless drill and
19mm hex head bit to adjust

12 QUICK TIPS TO
SET UP AND PACK UP
YOUR Air OPUS®
When folding the bed lids away,
always fold the rear bed lid first and
ensure all canvas is tucked in.
TIP 2
Take special care to ensure all canvas is
tucked away on all sides especially around
gas struts, hinge points and where the two
folding lids meet in the centre of the
camper.
TIP 3
To avoid placing too much pressure
on the latches and breaking the latch
hook, make sure you latch down the
overcentre catch that is closest to the
center first.
TIP 4
You can adjust the latch by turning it along the
thread, thus extending it to avoid excessive
pressure on the latches and breaking the latch
hook.
TIP 5
When using your key to open
and unlock the door, push the
door inwards on the seal to
take pressure off the lock and
it will open easier for you.

12 QUICK TIPS TO
SET UP AND PACK UP
YOUR Air OPUS®
During canopy inflation make sure
all external air valves are closed off
and the main air valve is open
before turning air pump on.
TIP 7
Before you set off on your first trip, do a couple of full set ups and while you have all the
canopy and annexe up, remember to weather-in the canvas and allow to dry completely
before packing up!
TIP 11
Remember to turn the MAIN INFLATION
valve in the camper to the horizontal
CLOSED position when inflation is
complete otherwise the canopy may
slowly deflate over time.
TIP 9 TIP 10
During annexe inflation make sure the external
air valves are closed off before turning air
pump on BUT MAKE SURE the annexe linking
tube valves are both OPEN so the air from the
canopy can flow through to the air beams.
TIP 8
If the beams are losing air slightly you can turn
the inbuilt air pump ON and that will top up
the air pressure in all air beams back to the
desired pressure, the pump will turn OFF
automatically.
External deflation valve To OPEN valve turn counter clockwise. To CLOSE valve turn clockwise until firm.
Remember to
open the main
valve while
inflating.

HITCHING & TRAILER
ELECTRICS
About your Coupling
7 PIN FLAT PLUG
The Air OPUS® is fitted with a 7-pin flat plug
that connects all the exterior trailer lighting
and the electric brakes to the towing vehicle.
A standard 7 pin plug is required on your tow
vehicle for this to connect to.
ANDERSON PLUG
The Air OPUS® is also fitted with a standard 50
amp Anderson Plug which is connected to the
Air OPUS® batteries. If you have an Anderson
plug on your towing vehicle that is connected
to your vehicle battery then you can attach
these two together whilst towing. Disconnect
these plugs when the engine of the towing
vehicle is not running, as it will continue to
draw current and you may end up with a flat
battery on your towing vehicle.
You can also use this Anderson plug to attach
a solar panel which will also charge your Air
OPUS® batteries. Your solar panel must have
a built in regulator. The Anderson Plug runs
through its own fused system located in the
battery box.
About your Electrical Plugs
The Air OPUS® comes with a DO35
off-road coupling.
When hitching the Air OPUS® to your towing
vehicle you must ensure that someone is close
to the handbrake in order to maintain control
of the trailer, particularly when manoeuvering
on uneven ground or a slope.
IMPORTANT
Wheel nuts should be checked
after first 100km and then
every 1000km.

Air OPUS®
BRAKE SET UP
About your Brakes
The Air OPUS® is fitted with electric trailer
brakes. You need an electric brake controller
fitted to your car in order to tow the Air OPUS®
and operate the electric brakes safely.
Before towing, check that the Air OPUS®
brakes are on. Refer to your vehicles brake
controller user manual. To test brakes,
connect to running car and use the electric
brake controller manual over ride
switch/button lever.
As part of the annual service check you
should have completed by an accredited
industry service agent, the brakes will be
checked and maintained.
IMPORTANT
Failure to tow with a brake
controller in your vehicle is both
dangerous and illegal and will
void warranty.

SETTING UP YOUR
Air OPUS® CAMPER
Once you have positioned your Air OPUS® level
in the desired location, engage the handbrake.
Levelling ramps may be required (not supplied).
STEP 1STEP 2STEP 3STEP 4
Using the leg winder supplied, gently lower
corner steady legs until each touches the ground
with enough pressure to stop any rocking.
Unclip the spare wheel carrier and lower it down
gently to the horizontal position, 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 5
Removed bed support legs.
Raise or lower the jockey wheel to level your
Air OPUS® lengthways.
Initial Steps
IMPORTANT
Corner support legs are only to
support the Air OPUS® NOT to
be used to level or lift.

opuscamper.com.au 13
SETTING UP YOUR
Air OPUS® CAMPER
Unlatch & open the front lid completely.
Gas struts are fitted to aid the process and
support the weight of the lid at this stage.
Secure the front lid to the front toolbox with
the over-centre latch and retaining pin.
STEP 6
Repeat the process with the rear lid and fit the
two rear bed support legs into place. Ensure
that the D-pin clips are fully secured on the rear
bed end section by inserting them through the
holes and securing them with the clip.
STEP 7
Walk around the Air OPUS® and inspect the tent to ensure that the canvas is properly
located within the aluminium channels and that no part of the tent is caught or snagged.
STEP 8
Turn the power key ON. Turn the pump master switch ON. Push the pump button and watch
your camper inflate!
STEP 11
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. If your camper is
fitted with corner straps, secure to hook. Make sure
that the door is zipped (closed) before inflation.
STEP 9
Ensure the main internal air valve is open
(vertical/in line). Tighten all external air valves on
each air beam (5 on tent and 7 on annexe).
STEP 10
Once pump shuts off, CLOSE the main internal valve to lock off air system. You may also wish to
close some cross linking valves to retain constant pressure over an extended stay.

Air OPUS®
WATER SYSTEM
The Air OPUS® is fitted with two 80L freshwater tanks. With one unit mounted in front of the axle
and the other unit mounted behind the axle. Each water tank has its own lockable fill point
located on the driver side of the body of the Air OPUS® and is plumbed to a 12V switchable water
pump located on the circuit board.
The two tanks are both plumbed to the same water pump via a 3-way valve located next to the
water fittings on the drivers side. This valve is used to switch between the two tanks or to draw
from both equally.
The plumbing system is connected to the kitchen, the shower and the outlet on the drivers side.
This outlet can be used to plumb into an external hot water service which is plumbed back into
the adjacent inlet supplying hot water to both the kitchen and shower.
- Red plugs / dust caps must be removed before turning pumps on.
Water System Set up

opuscamper.com.au 17
Air OPUS®
WATER SYSTEM
The kitchen has a drain hose attached to the sink drain. This is designed to drain cold water to a
waste container/bucket. As the Air OPUS® is a cold-water unit.
The water pumps are pressure operated, so once the main 12 Volt power switch is turned on at the
circuit board, the pump will prime the system and as soon as you turn the tap on the water will
flow. Once the tap is closed the pump will turn off until the tap is turned back on.
When the water system is not required Air OPUS® recommends switching off the pump when
not in use.
When packing away the Air OPUS® follow the procedure below to drain the system of any excess
water before disconnecting the water inlet and internal waste pipe:
IMPORTANT
A SMALL AMOUNT OF WATER
MAY BE PRESENT FROM THE
CONNECTORS AND WASTE HOSE,
SO A CLOTH IS USEFUL TO
REMOVE ANY EXCESS WATER.
A. Switch off the pump at the mains power switch.
B. Open the tap & allow the excess water in the pipe to drain.
C. Close the tap once all the water has drained.
D. Disconnect either side of the male-to-male hose coupler.
E. Place the bottom wastewater outlet pipe away under sink.

Air OPUS®
GAS SYSTEM
IMPORTANT
CHECK THE INSTRUCTIONS FOR CORRECT
FITMENT AND SAFE USE WITH THE GAS
CYLINDER MANUFACTURER/SUPPLIER.
The Air OPUS® is fitted with a mount for two 9kg
gas bottles. The bottle is to be connected to gas
regulator and must be turned off when the gas is
not in use.
PLEASE refer to the information located on the rear of your
OPUS® gas certificate.
STEP 1
To install a gas cylinder, ensure the gas cylinder is placed correctly with J-clamp, continue
with attaching the gas hose to bottle ensuring that’s its been tightened so no leaks occur.
Eg. like getting a gas bottle and attaching it to your BBQ at home. First connect the gas hose
onto the cylinder. It is advisable to keep an adjustable spanner with jaw opening up to 30mm
for this use.
STEP 2
The gas tap/valve on the top of the gas bottle can now be opened.
STEP 4
Turn on the yellow gas tap (situated underneath the rear of the OPUS behind each of the gas
outlets unit) by turning 90°.
STEP 5
Lift up lid of the gas hob, turn on one of the burners (push in, hold the knob down until flame
is lit and stays on. Keep pressing the button until the gas has had time to fill up the system
and the burner will ignite.
STEP 6
Ensure that the gas bottle valve is closed prior to packing up the Air OPUS® for transit or
storage. The Air OPUS® has two gas outlet bayonet fittings. At each point there is an on/off
valve located right behind the gas outlet. Each valve must be turned off when not in use.
The outlet on the driver’s side is a gas BBQ (not supplied) while the outlet on the passenger side
is to supply the 4 burner cook top in the slide-out kitchen. This hose is fitted to the cook top and
is located under the sink. Both of these points should have the protective plugs inserted when
not in use.
For use when Annex is set up, make sure both ventilation points are clear and not covered, one
on the drop skirt and the other on the roof of the rear pod.
When the gas is not in use the shut off valve and gas bottle should be in the off/closed position.
Gas fumes inside a camper trailer tent could result in unconsciousness, brain damage or even
death. Follow safe operating procedures with gas at all times:
• Ensure good ventilation throughout, at ALL times
• Do not use any other gas systems than those provided with the Air OPUS® camper
inside the tent
• Always turn off the shut off valve IMMEDIATELY after use.
STEP 7
Once kitchen has been pulled out full you can fit the gas bayonet hose to the outlet. This is a
simple push and twist to install.
STEP 3
