Section 8: Plumbing System
12-volt Water Pump
There must be sufficient 12-volt DC power to run the water pump when your recreation ve-
hicle is not hooked up to city water. Once activated, the water pump (also known as the de-
mand pump) will self-prime, and provide water. The water pump continues to run until
maximum pressure is achieved and shut off. The water pump will automatically re-start
when it senses a drop in the water pressure. The pump is designed for . Using the pump
continuously or with high pressure will shorten the life of the pump and is not covered in
your warranty.
Some cycling may occur, depending on the volume of wa-
ter being released. The water pump is engineered with a
check valve to prevent water from back flowing into the
fresh water supply tank.
™ NOTE: The water pump switches should be in
the OFF position when the recreation for any
amount of time.
Maintenance
Periodically check the in-line water pump strainer for accumulated debris. To clean, shut
off the water pump, unscrew the clear cap, remove the re-useable metal strainer, clear any
debris, then reinstall.
Normal pump maintenance consists of checking and cleaning of the strainer, normal sanitiz-
ing and winterizing and occasionally checking all plumbing hardware and fittings for tight-
ness. Lack of sanitizing can lead to premature pump failure and poor performance over time.
Scale build-up on the diaphragm and valves, can cause low flow and leak back (occasional
pump cycling with no faucets open or tank filling up when hooked up to city water).
For additional information on the care and operation of the pump, read the safety and operat-
ing information in the pump manufacturer's owner's manual.
Water Pump Switch
Most water pump switches illuminate when the water pump is activated. Typical switch
locations are in the back of the unit or on the monitor panel, or the switch may be art of a
touchscreen system (if so equipped). When the water pump switch is ON the pump runs until
45 lbs. of pressure has been achieved. The red light will stay on.
Water Purification System
The canister filter is the primary filter used for the complete water system. If the water sup-
ply has not been used for some time, allow the water to flow for several minutes to flush the
system.
Do not allow water in the canister housing to freeze.
Remove the filter before using anti-freeze to winterize the system or
chlorine solution to sanitize the system.
Flush canister housing thoroughly before it is put back into service after
winterizing or sanitizing.
For best results replace filter every 6-12 months.
Do not use carbon cartridges where water is microbiologically unsafe or
of unknown quality.
Maximum operating pressure is 125 psi (8.75 bar).
Maximum water temperature is 125° F (52° C).
