OWNER’S MANUAL
Series

Thank you for choosing a Helio ultralight trailer. We are happy to
welcome you to your new lifestyle, which will allow you to travel
everywhere, hassle-free. At Helio, we are proud of our products
and have invested much time in their conception, especially in the
R&D and ergonomics departments. We use quality equipment
and components in order to oer you a trailer that meets all of
your expectations.
Your Helio trailer is conforms to all applicable Canadian and U.S.
federal motor vehicule safety standards in eect. The equipment
contained in your new trailer must be used in accordance with
the Helio manufacturer’s specications as well as the other
manufacturers’ terms of use for the equipment and accessories
included in your trailer. In order to ensure the longevity and
durability of your Helio trailer, some maintenance work must be
attended to.
Before using your trailer, we therefore suggest that you read
attentively all of the dierent documents included in your
trailer for you to become more familiar with it. Should you have
any questions, do not hesitate to contact your Helio dealer.
Please read all the documents provided with your new trailer,
including all the Helio warranty information and appliance
warranty registrations by lling out and returning by post
all the individual warranty cards for each of the respective
manufacturers.
Please follow and observe all the instructions and warnings
regarding the use of your trailer. Remember that accidents are
generally caused by omitting to observe basic and fundamental
safety instructions and precautions. Accidents can be prevented
by recognizing the cause of the accident and avoiding the action
or inaction that may cause them. An attentive owner is the best
insurance against accidents.
Your Helio trailer has been thoroughly inspected before delivery.
However, to ensure your complete satisfaction, an inspection
of the dierent components will be conducted with you before
delivery. Use this time to ask your questions about the product.
This introduction will help you become more familiar with your new
Helio trailer and its components, while giving you the assurance
that everything is working well.
If you are not familiar with towing a trailer, ask all of your questions
at this time. Your Helio has been built for recreational and short-
term use. It is not meant to be used as a permanent residence.
If you encounter a problem for which you need assistance, contact
your Helio dealer. If there is a problem with one of the appliances,
check the appliance manufacturer’s information in the envelope or
on the USB ash drive.
If you encounter a problem with your trailer while you are traveling
and the trailer is still covered by the warranty and you cannot nd
a dealer nearby, contact your Helio dealer as soon as possible
BEFOREHAND in order to have the cost estimate approved and
the repairs done by an independent RV center. Your dealer can
let you know what the warranty covers. If a component covered
by the warranty needs to be replaced, return it as well as your bill
to your Helio dealer. This will allow your dealer to take note of
the problem and ensures your expenses will be aptly reimbursed.
Alterations made to your trailer without Helio’s written
authorization can lead to a warranty reduction or loss of
coverage. Make sure you contact your dealer before such
alterations are made.
We reserve the right to alter the make or material of any component
at any time, without incurring any obligation to make any such
modications in trailers previously sold.
We wish you a pleasant time in a peaceful state of mind and hope
your Helio will help you create some great memories.

Propane gas containers must not be placed or stored in an RV living
space. Propane gas containers are equipped with safety devices
that get rid of extra pressure by releasing gas into the atmosphere.
Propane is a very ammable gas. Failure to conform to these
guidelines may cause a re or explosion resulting in severe personal
injury or death.

For cooking appliances to operate safely, it is important to let in
fresh air. Before turning them on, open the roof air vent, door
and/or window. Propane gas ames consume oxygen that must be
replaced for there to be adequate combustion. Improper use can
result in severe personal injury or death.
Warning labels are located in the cooking area to remind you to
let in enough fresh air for combustion. Unlike houses, the amount
of oxygen is limited in the smaller space of an RV. Adequate
ventilation when using cooking appliances will prevent the risk
of asphyxia.
Make sure your propane gas tank has been well installed. Check
that the connection with the propane gas collector has been made.
For any questions, ask your dealer to explain how to ll up your
propane gas tank and check the system’s sealing.

Note:
Leave the emergency exits unobstructed, and make sure everyone
in your RV knows the location of all exits, including the window exits.
Make sure everyone in your RV knows how to use and where
to locate the re extinguishers.
Familiarize yourself and all the other RV occupants with the
following procedure (PASS):
• Pull: pull the pin (some re extinguishers may have a cartridge
you have to push)
• Aim: point the nozzle toward the base of the re
• Squeeze: press the handle to release the extinguishing agent
• Spray: spray the base of the re (If you aim for the ames,
you will not put out the re.)
Testing laboratories classify res into three classes:
• Class A: res arising from wood, paper, fabric, rubber,
and certain types of plastic
• Class B: ammable liquids, such as grease, cooking oils,
gasoline, or kerosene
• Class C: electric re caused by a live electric wire or a
short-circuited engine or switch

Tire safety
Use the following information to make tire safety a regular and
integral part of your vehicle maintenance routine.
Evacuate everyone from the recreational vehicle immediately.
DO NOT ATTEMPT TO PUT OUT A FIRE WITH WATER.
Water can spread certain types of res and cause electrocution. Exit
the vehicle immediately and call the re department. Propane gas
regulators must always be installed with the vent directed downwards.
Regulators that are not in compartments have been equipped with
a weather cover. Make sure the regulator vent faces downwards and
the weather cover is placed so as to minimize the blocking of the vent
(this can lead to excessive gas pressure resulting in a re or explosion).

TIRE PRESSURE AND LOAD LIMITS
Your vehicle’s recommended tire pressure and load limits
Tire information placards and vehicle certication labels contain
information on tires and load limits. These labels indicate
the vehicle manufacturer’s information, including:
• Recommended tire size
• Recommended tire ination pressure
• Vehicle capacity weight (VCW – the maximum occupant and cargo
weight a vehicle is designed to carry)
• Gross Axle Weight Rating (GAWR – the maximum weight the axle
systems are designed to carry).
When taking the trailer out of storage, inspect the tires carefully
and make sure there are no cracks in the grooves and no cord
is apparent. Cracks in the sidewall may indicate internal damage
or separation in the tire.
Tires and load limits
Tire ination pressure is the level of air in the tire that provides it
with load-carrying capacity and aects the overall performance of
the vehicle. The tire ination pressure is a number that indicates
the amount of air pressure – measured in pounds per square inch
(psi) – a tire requires to be properly inated. This number can also
be expressed in kilopascals (kPa), which is the metric measure used
internationally.
Vehicle manufacturers determine this number based on the vehicle’s
tire size and the vehicle’s design load limit, that is, the greatest amount
of weight a vehicle can safely carry. The proper tire pressure for your
vehicle is referred to as the “recommended cold ination pressure.”
To get an accurate tire pressure reading, you must measure tire
pressure when the tires are cold. A cold tire is one that has not been
driven on for at least three hours. When you drive, your tires get
warmer, causing the air pressure within them to increase. Therefore,
you can only get an accurate tire pressure reading if the tires are cold.
Checking tire pressure
Given that tires are designed to be used on several types of
vehicles, tire manufacturers provide the maximum permissible
ination pressure on the tire’s sidewall. This number represents
the maximum ination pressure to which a tire may be inated
under normal driving conditions.
Note:
It is important to check your vehicle’s tire pressure at least once
a month for the following reasons:
• Most tires may naturally lose air over time.
• Tires can lose air suddenly if you drive over a pothole or if you strike
the curb when parking.
•
With radial tires, it is usually not possible to determine underination
by visual inspection. For convenience, purchase a tire pressure
gauge to keep in your vehicle.
TIRE SAFETY TIPS
Preventing tire damage
• Slow down if you have to go over a pothole or other object in
the road.
• Do not run over foreign objects in the roadway, and try not to
strike the curb when parking.

Tighten each lug nut in the order shown in the diagram below.
Start by tightening all the lug nuts by hand to prevent cross
threading. Torque requirements for lug nuts vary according to
the size and manufacturer of the wheel. Always follow the wheel
manufacturer’s recommendations. The nal tightening torque
must be 85 to 95 ft-lbs.

Practical tips regarding tires:
• Make sure all wheel lug nuts are securely tightened. Use a torque
wrench.
• This is the only way to ensure the nuts are tightened.
• Inspect tires for uneven wear patterns on the tread, cracks,
foreign objects, or other signs of wear or trauma.
• If you are towing a trailer, remember that part of the trailer’s
weight is transferred to the tow vehicle.
• A trailer’s hub bearings must be greased after a long storage
period.

• Remove bits of glass and foreign objects wedged in the tread.
• Make sure your tire valves have valve caps.
• Check tire pressure before going on a long trip.
• Do not overload your vehicle. Check the Tire Information Placard
for the maximum recommended load for the vehicle.
• When towing your trailer, remember that part of the trailer’s

Air pressure
Remember that the air pressure inside your trailer’s tires is not
the same as that in your car or SUV’s tires. Always maintain proper
tire pressure. Avoid under or over ination.
Under ination can cause heat build-up in tires, which reduces
a tire’s useful life and lowers the trailer’s security load limit. Over
ination can lead to dicult and irregular driving, which can
damage the trailer or the load. Cold ination pressure refers
to a tire that has not been driven on for at least three hours or
has been driven on for less than 2 km (1,25 miles). A hot tire’s
ination pressure can indicate a 6 psi increase compared to that
of a cold tire.

Spare tire and tire change
Safety is the rst priority when a tire needs to be replaced during
your trip.
The Helio O Series trailers are equipped with a spare tire.
It is located under the trailer, in the back. Follow these steps
to use the spare tire:
1. If a at or damaged tire occurs while driving, stop your
vehicle and trailer gradually and in a controlled manner.
2. Slowly pull up on the side of the road.
3. Turn on your four-way ashers.
4. If a at or damaged tire occurs at night, use ares or warning
lights also.
5. Use a wheel chock to block the opposite wheel.
6. Slightly raise the trailer using a hydraulic or scissor jack
placed directly under the trailer’s aluminum frame.
7. Loosen hub bolts.
8. Use jack to raise the tire from the ground.
9. Remove hub bolts and keep them together somewhere easily
accessible.
10. Remove the wheel and replace it with the spare wheel
and tire.
11. Replace hub bolts and tighten them by hand.
12. Lower the wheel and tighten hub bolts by following
the sequence above.
13. Put away the at tire, jack and all safety tools and equipment.

After changing a at tire, have it repaired or replaced as soon as
possible. If you have a at tire but no spare tire or you are unable
to x it yourself, contact a towing company or support center.
If you must leave the trailer for any reason, make sure your trailer
is well stabilized so it doesn’t move.
3. WEIGHTS & LOADING
Denition of weight terms
GVWR (Gross Vehicle Weight Rating) – maximum allowable gross
weight of the trailer and its contents.
GAWR (Gross Axle Weight Rating) – maximum gross weight that
an axle can safely support.
Note:
Do not take for granted that it will be possible for you to ll all
the tanks and storage spaces and still be within the GVWR limits
shown on the compliance label.
Tow vehicle requirements
When buying a tow vehicle, keep in mind the following
requirements regarding safety and usability:
1. Transmission – The transmission can be manual or automatic,
but an automatic transmission better controls engine charges.
2. Power
– Make sure your vehicle has sucient power to
hitch your trailer on the type of roads you’ll be taking. Here
are the factors to take into account: engine power, cooling
capability, and axle ratio. Discuss your vehicle’s towing capacity
with your dealer.
3. Tires and suspension – It is important to make sure your
vehicle’s tires and suspension are designed to support the
additional capacity needed to haul a trailer. Refer to your
dealer and your vehicle’s owner’s manual for the type of tires
and pressure required.
4. Coupling – Your vehicle must be equipped with a hitch
whose rated towing capacity is equal to or greater than the
trailer GVWR. Make sure it is installed according to the hitch
manufacturer’s instructions and it satises the adaptation and
performance requirements of the tow vehicle. Also make sure
Never use the back stabilizer bar as a jack to raise the trailer at
any time or even for a at tire. Please refer to the manufacturer’s
recommendations.

to install the appropriate electrical cables providing a 12 V
electrical current to the trailer turn signals and brake lights.
5. Safety equipment – Install the appropriate safety equipment
such as side view mirrors on the tow vehicle. In most states or
provinces, these are required by law. Most available kinds are
not permanent and can easily be installed or removed.
Cables
In addition to the hitch, it is also necessary to install the appropriate
electrical connection between the tow vehicle and your trailer.
A exible connector at the end of the vehicle is provided with wires
long enough for it to connect to your vehicle’s electrical system.
Make sure you select the proper gauge for your length of cable, with
enough slack between the trailer and tow vehicle to permit tight
turns, but not be close to the road surface to drag. Ask your vehicle
dealer or hitch installer to help you with the installation.
Cable color code
The cable color code for connections is as follows:
White – grounding
Green – tail light, side marker light, and running light
Red – left turn signal and brake light
Brown – right turn signal and brake light
Blue – electric brakes
Black – interior lighting and accessories
Although your Helio trailer has been inspected at the manufacturing
plant, we recommend you visually inspect all the lights to make sure
they work before leaving the dealer’s.
Electrical hook-up (7 pin)
Place the trailer’s exible connector into the jack located on the tow
vehicle. Make sure you leave enough slack to avoid separation on
tight turns. Check that all lights work before setting out.

Brakes
Your trailer’s brakes are wired to the tow vehicle via a exible
electrical connection that allows the braking eect to be
uniformly distributed to the tow vehicle and trailer. Refer to your
electric connection installer for 7 pin wiring to know the types
of brake controllers available and the appropriate installation of
your vehicle’s controller.
Ask them to explain how the electric brakes work and how to use
them adequately, as well as the importance of the ballast resistor
and the breakaway safety switch.
Test the brakes and adjust them, if needed, according to the
brake controller manufacturer’s instructions. Adequate brake
adjustment can help prevent dangerous wandering or a jackknife
occurring on a slippery road or when making an emergency
stop. Before leaving on a trip, perform a short road test to check
that the brakes are working well. Press the brakes several times
at dierent speeds and pressures. In case of wheel lockup,

the brake shoe adjustment is too tight. If the trailer does not brake
adequately, the brake shoe adjustment is not tight enough. Do
not drive faster than 45 km/h (28 miles/h) during this road test.

adjustment, maintenance, and troubleshooting procedures.
Coupling the trailer to the tow vehicle
When attaching the trailer coupler to the tow vehicle’s hitch,
follow these steps:
1. Raise the coupler by rotating the operating lever of the rear
wheel clockwise.
2. Back up the tow vehicle until the hitch ball is aligned under
the coupler. Ask someone to help you by using predetermined
hand signals. Make sure this person is visible at all times and
proceed slowly and cautiously.
3. Raise the coupler locking bar.
4. Lower the coupler onto the hitch ball by rotating the operating
lever of the rear wheel counter clockwise. Allow the coupler to
fully engage the hitch ball.
5. Lower the coupler locking bar, and make sure it is locked in
place using a lock pin or safety lock.
6. Raise and lower the rear wheel against the tow vehicle’s hitch.
Safety chains
After attaching the trailer coupler to the hitch ball adequately,
the safety chains must be rigged. According to safety regulations,
safety chains must crisscross underneath the tow bar and hitch to
prevent the tow bar from falling to the ground in case of hitch or
coupler failure.
Connecting safety chains
1. Crisscross the chains underneath the tow bar and hitch.
2. Loop the hooks around a member of the frame of the tow
vehicle or attach them to holes provided in the hitch system.
3. Make sure the slack in the chain lengths is equal on both sides
and there is enough to permit tight turns, but not be close to
the road surface to drag.
Do not attach safety chains to the bumpers of the vehicle.

Before leaving on a long trip
Whether you are setting out from your home, a rest area, or a
camp site, you must check the following before leaving on a trip
inside or outside your trailer.
• Tires
These must be inspected before each trip. A tire must be
replaced when it is worn 1/16 inch deep in at least two adjacent
grooves, in three spots on the tire’s surface. Check for uneven
wear, foreign objects, bumps, or excessive chipping. When
buying new tires, make sure they are the same size and have
the same ply rating and load range as that of the old ones.
Do NOT mix radial tires with bias or belted bias tires.
Each morning, check the state and pressure of the tires of your
trailer and tow vehicle. The heat caused by surface friction
increases a tire’s air pressure by about 6 to 9 psi. Therefore, do
not drain a hot tire of its air. Inate the tire to its recommended
pressure, as indicated on the tire or in the tire manufacturer’s
instruction leaet.
• Wheel nuts
These must be tightened before you leave, then at every
100 km (62 miles) for the rst 300 km (187 miles) during your
initial voyage, and after each tire replacement. Afterwards,
tighten wheel nuts regularly, then again before using your trailer
after a storage period.
• Lubricate hub bearings
For more details, see the axle reference in the Section 6:
Maintenance & Troubleshooting for axle and electric brake. It is
generally recommended to lubricate hub bearings at least once
a year or at every 18,000 km (11,000 miles).
• Hitch
Check the hitch to ensure it has not loosened. The lock pin
or safety lock must be installed in the coupler.
• Front end
Make sure the front end is aligned horizontally with the hitch
and coupler is locked in this position. The recommended height
for the hitch is around 15 inches (38 cm) from the ground to
2 inches (5 cm) above the hitch ball.
• Propane gas tank
The connections must be tightly made and the service valve
turned on or o according to the following instructions. Certain
states or provinces prohibit vehicles equipped with a propane
gas tank from using tunnels. Other states or provinces prohibit
anyone from travelling if the service valve is turned on. Check
the regulations of the states or provinces you plan on visiting.
• Safety chains
Safety chains must be properly rigged to the tow vehicle.
• 7 pin exible connector
It must be correctly connected to the tow vehicle’s electrical
system.
• Tail, stop, and turn lights and headlights
Trailer and tow vehicle lights must be checked, including brake
lights, turn lights, four-way ashers, night lights, tail lights, and
tow vehicle headlights.
• Interior lighting and electrical panel
Make sure all interior lighting is turned o and the power supply
is turned “ON” to allow the recharging/maintaining of the
battery by the front vehicle.
• Power cord
The 120 V external power cord must be unplugged from its
external power source, placed in the storage box, and the ap
well shut.
• Water hose
The exible hose must be disconnected and placed in the
storage space with the cap well closed.

18
• Tanks
The freshwater, waste, and propane gas tanks are lled
adequately.
• Sewer drain hose
The sewer hose must be disconnected and stored in the sewer
hose compartment under the trailer. The waste tank valves
(Gray – Black) are closed, and the waste outlet cap is well
tightened. Please dispose of wastes in an authorized area.
• Roof air vent
Make sure the roof air vent/fan is well shut and the crank is in
locked position.
• Inside doors and drawers
Make sure the doors, windows, and drawers are well closed.
Loose objects must be secured or stored.
• Refrigerator door
The refrigerator door must be secured using the travel lock.
• Outside storage door
The access door to the inside storage must be closed and locked
using the appropriate key.
• Outside handspray
The access door to the outside handspray must be closed and
locked using the correct key.
• Step
Check that the integrated step is in stored position.
• Porch light
Make sure the outside light is turned o when traveling.
• Main door
Both door locks must be locked using your main key.

4. SYSTEMS & COMPONENTS
Propane gas (O2 & O3 Series)
Your trailer’s propane gas system supplies the fuel necessary for
cooking, optional heating, and water heating. Propane gas can
also be used as another energy source for your refrigerator.
When manipulation and safety precautions are observed, propane
gas can be a clean, ecient, and safe form of energy. It allows you
to benet from a comfortable lifestyle at a time when other forms
of energy cannot be used.
The propane gas is stocked in liquid form in a special storage tank.
This tank is xed on the chassis at the front of the trailer, next
to the hitch and coupler, and is protected by a berglass case,
which also contains the deep-cycle battery.
The propane gas is stored under extreme pressure in the tank,
with enough space to allow for expansion under vapor form.
The pressure of this vapor is reduced when it goes through a
regulator. This reduction of pressure is a two-step process that
ensures constant pressure in the propane gas used, no matter
the outside temperature, climate, or altitude.
Propane gas tank
Propane gas tanks are tested to sustain pressure levels exceeding
those usually met during expected normal use. Furthermore, all
propane gas tanks are equipped with an integrated safety device
that regulates the extent to which they should be lled. Propane
cylinders are designed to be lled with propane gas at only 80%
of their capacity. With the cylinder lled to only 80% of its capacity,
this leaves 20% of space left for vapor. This extra space allows
the vapor to recede via the Acme QCC1 connection while also
providing space for the liquid to expand. If the tank were
completely full, an increase in the outside temperature could
cause a propane gas discharge via the expansion valve.
Filling up your propane gas tank
Before removing a propane cylinder to ll it up or perform
work on the propane gas system, blow out all open ames and
discontinue the use of any fumigant.
1. Disconnect all devices running on propane gas and turn o all
pilots (water heater, refrigerator, heating (optional).
2. Shut o the service valve on the propane gas tank and remove
the Acme QCC1 connection, which is threaded left hand and
must be twisted clockwise to be removed. Never use a wrench
to shut o the service valve. If a leak occurs while shutting it o
manually, have the service valve repaired or replaced.
3. Install a cap or block the entrance of the service valve to prevent
any penetration of dust or dirt.
4. Untighten the bolt on the clamp ring, then remove the tank from
the trailer. Always transport the propane cylinder in a vertical
position. Never transport, install, or use a vertical tank in a
horizontal or upside down position.
5. Bring the tank to a qualied propane gas supplier who observes
the regulations in eect.
6. Ask the supplier to plug the nozzle to your tank’s lling up
connection.
7. Although the tank is equipped with an automatic stop valve
at 80%, which prevents the lling up of the tank past 80% of its
capacity, let the supplier check the 20% liquid tank level gauge
and stop the lling up process if liquid appears.
Propane gas regulator
The regulator reduces the pressure of the propane vapor inside the
tank to that required for household appliance use. The regulator
rarely requires maintenance. Always protect it from the elements
and extreme temperatures.
The regulator has been preregulated by the manufacturer,
and adjustments should not be necessary. However, should
