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 automatical-
ly supply water pressure as it is needed. It is rec-
ommended 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.
Pump Strainer Filter
The pump is equipped with a cleanable strain-
er filter to capture any possible tank borne parti-
cles that could damage pump components.
Note:
We recommend that you check and clean
this filter after each tankful of water dur-
ing the first few uses of the water pump
system. Thereafter, remember to check it
at least yearly, such as during winteriza-
tion 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.
•
Lower valve handle to lock filter and restore
water flow.
See “Winterizing Procedure”.
DISINFECTING FRESH WATER

To assure complete disinfection of your fresh
water system, it is recommended that the
following procedure be followed on a new
system, one that has not been used for a period of
time, or one that may have become contaminated.
This procedure is also recommended before long
periods of storage such as over winter.
