PLUMBING
NOTE:Ensure 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.
UTILITY LIGHT
A light is located on the sidewall to illuminate
the utility hook-up area when needed.
The switch is located in the water service
center compartment.
WATER PUMP
When your motorhome 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 waterline 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 Waterline
Priming” for instructions on using the water
system for the first time.
Water Pump Strainer
The pump is equipped with a cleanable
strainer to capture any possible tank-borne
particles that could damage pump components.
NOTE: We recommend that you check and clean
the strainer after each tankful of water
during the first few uses of the Water
Pump system. Thereafter, remember to
check it at least yearly, and be sure to
empty water from it if using the blowout
winterization procedure.
To Clean Pump Strainer
•
Ensure all Water Pump switches are OFF.
•
Twist the inlet cap (bowl) “counter-
clockwise” to unscrew from the strainer
assembly.
•
Remove the bowl and pull the strainer screen
out of the bowl to tap out any particles and
rinse clean.
•
Insert the strainer screen back into the bowl,
then screw the bowl back onto the strainer
assembly.
Water Pump Switch
The Water Pump switch is located on the
monitor panel (some models may have an
additional switch in the water service center, near
the exterior shower, or within the bathroom area
for your convenience).
While the switch is “ON”, the pump will
automatically supply water as it is needed.
