2. Turn Fresh Water Valve to Normal position
and turn the water pump switches OFF.
NOTE: Always keep the tank fill valve in Normal
position unless you are filling the tank. If
this valve is left in the Tank Fill position
while using the city water, water will
keep flowing into the tank and out the
tank vent tube onto the ground and the
water pump will run without delivering
water to faucets.
Disconnecting from City Water:
1. Turn the city water source off.
2. Open a faucet on the coach (such as the
exterior wash station if equipped) to relieve
line pressure.
3. Disconnect the city water hose from the coach
and replace the cap on the fresh water inlet.
NOTE:Be sure the Fresh Water Valve is in
Normal position to use the water pump.
If the valve is in Tank Fill position, the
pump will run continuously without
delivering water.
Pressure Regulators
Because city water pressure varies from
location to location, we recommend obtaining an
in-line water pressure regulator to prevent
damage to any components, connections and
seals in your fresh water system.
We recommend a regulator that controls water
pressure to
50 psi . max .
These devices simply connect in-line between
the supply hose and the city water input on the
coach.
Water pressure regulators are commonly
available at any well stocked RV dealership and
many large retail discount or home supply
centers.
UTILITY LIGHT
A light is located up on the left sidewall to
illuminate the utility hook-up area when needed.
The switch is located in the water service
center compartment.
WATER PUMP
When your coach is not connected to a city
water supply, water is supplied from the fresh
water tank by a water system demand pump. A
demand pump is designed to run only when you
are using water. When you open a faucet, the
water line pressure drops and the pump begins to
run, and it will continue to run as long as the
faucet is open. When you close the faucet, the
line pressure backs up to the pump, and it shuts
itself off.
The pump is self-priming and will run briefly
to build up line pressure when the Water Pump
Switch is first turned on. See “Initial Water Line
Priming” for instructions on using the water
system for the first time.
