Pressurized Water Supply (Water System); Transporting Water When Traveling; Water Pump - Helio O Series Owner's Manual

Pressurized water supply (water system)

To use water from a pressurized external source (city water),
follow these steps:
1. Make sure the sink and shower faucets are turned off.
2. Remove the city water connection cap, located on the outside
wall.
3. Connect a good-quality pipe to the trailer connection and the
city hydrant connection. Use a regulator to ensure pressurized
flow (max 45 psi). Remember to use different-colored
collapsible hoses for the filling up and emptying of the tank
to avoid possible contamination of your water system.
4. Open the city hydrant. Turn on the kitchen faucet. Make sure
the collapsible hose is not bent, as this could limit water flow.
Note:
A check valve in the system prevents the water from filling up
the interior water storage tank.

Transporting water when traveling

When traveling, you may want to empty the tank or only keep the
minimum water amount. This will reduce the trailer's total weight
while traveling. The fresh water tank's blowdown valve is located
at the back of the unit, next to the drinking water tank.
Note:
• When emptying the tanks, make sure the water pump is turned off.
• When emptying the entire on-board fresh water system, make
sure to turn on the faucets, the water heater drain, and the drains
located at the bottom of the system to remove all the fresh water
from the system.
• If the trailer is not used for a prolonged period, it is strongly
recommended to cut the water supply to the hose connection.

Water pump

When using water from the fresh water tank, the system must
be pressurized. A self-priming 12 V pump has been provided for
this purpose. The on/off switch for the pump is located in the
control panel located above the fridge. Turn on the switch to
activate the pump. Once activated, the pump automatically
starts every time a faucet or valve is turned on, which creates
a demand in water. When the water flow is cut, the pump stops
as well.
When using the pump for the first time after filling up the fresh
water tank, water may spray out of the faucet until the air is
completely emptied from the water pipe. This is a perfectly
normal situation and does not indicate an irregularity in regards
to the pump. When using the internal water supply, leave the
pump activated because it only works when the system has a
demand for it. The water pump is equipped with a screen to catch
debris and must be cleaned regularly.
CAUTION
CAUTION
Do not activate the water pump when using water from a
pressurized external source.

CAUTION
Filling up the system
If your trailer is equipped with a shower, let the entire system
(water tank, water heater, and water pipes) fill itself up before
using the water heater. When using water from an internal or
external source, turn on the faucets to allow the water to circulate
in the system. Once the water flow is regular and free of air, turn
off the faucets. Make sure the water heater is filled before turning
on the pilot.
