to run as long as the faucet is open. When you
turn the faucet off, 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.
Water Pump Switch
Water pump switches are located on the
systems monitor panel and in the water center
compartment (See Section 6). While the switch is
in the “ON” position, the pump will
automatically supply water pressure as it is
needed. It is recommended that the pump switch
be turned off whenever you are away from the
vehicle or not using the water system. A slow
leak in a faucet could drain the water system and
discharge the coach battery.
Initial Water Line Priming
1. Make sure that all water drain valves are
closed, including water heater valve.
2. Turn water pump switch to “OFF” position.
3. Fill water tank.
4. Open all faucets, hot and cold.
5. Turn on pump switch.
6. Close each faucet as it begins to deliver a
steady stream of water (close cold water first).
Leave hot water faucets on until they also
deliver a steady stream of water. This will
ensure that the water heater is filled with
water.
7. Check to be sure pump stops soon after all
faucets have been closed.
8. Pump is now ready for automatic operation.
Pump will start when a faucet is opened and
stop when the faucet is closed.
Pump Strainer Filter
The pump is equipped with a cleanable
strainer filter to capture any possible tank borne
particles that could damage pump components.
Note:We recommend that you check and clean
this filter after each tankful of water
during the first few uses of the water
pump system. Thereafter, remember to
check it at least yearly, such as during
winterization procedures.
To Clean Pump Strainer
Be sure all water pump switches are OFF.
•
Twist the inlet cap (bowl) counterclockwise to
unscrew from the filter 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 filter
assembly.
