lines and to the water heater. When ready, gradually open the hot and cold water at the sinks
and tub to clear air from the lines (it can be normal to see water "spit" from the faucets until
the system is pressurized). Close the faucets when the water is owing freely.
Water Pump
When you are not connected to city water (e.g., campsite water) and want to use water in your
motorhome you will need sucient 12 volts DC power to run the water pump. Once turned
ON at the monitor panel, the water pump (also known as an on-demand pump) will self-
prime and provide water.
OPERATION
e water pump is designed for use on an as needed basis. Using the water pump continuously
or with high pressure will shorten its operational life and is not covered by warranty. e
water pump has a check valve that prevents water from back owing into the fresh water tank.
Before operating the water pump:
1. Make sure there is adequate water in the fresh water tank.
2. Be sure the water heater bypass valves are set correctly according to your water system
label.
3. Open all the faucets (rst hot, then cold) including your interior and exterior shower
faucets.
4. Turn the pump switch ON, and allow the water pump to ll the water lines and hot water
tank. Aer water is owing in a steady stream from all your faucets, turn the faucets OFF.
e water pump should stop operation automatically when all faucets are closed. e
pump should now run "on-demand" when a faucet is opened, and stop when the faucet is
closed.
WATER PUMP STRAINER
If so equipped, periodically check the in-line water pump strainer for accumulated debris. To
clean the water pump strainer shut OFF the water pump, unscrew the clear cap, remove the
reusable metal cartridge, clear any debris, and reinstall the strainer and cap.
NOTE: Do not turn the water pump ON
if the fresh water tank is empty. Doing so
could cause damage to the water pump, or
blow a fuse.
NOTE: Do not turn ON the water pump
when using water from an external source.
Only run the water pump if using potable
water stored in your fresh water tank.
NOTE: The water pump should be
turned OFF when the motorhome is left
unattended for any amount of time. This
may help limit potential damage should
something fail within the water system.
