NOTE: To fill the fresh water tank without a pressurized water
source, refer to SANITIZE (Siphon Fill) section, and use a
container holding fresh potable water and a hose. Water will be
drawn into the tank by the pump. There is no gravity fill inlet on the
recreation vehicle.
"CITY WATER" (Pressurized fresh water source)
1.
Connect the fresh water hose to the city water inlet.
2.
Set the color coded valves to the CITY WATER setting:
(A) White handle pointing down
(B) Blue handle pointing left
(C) Green handle pointing left
(D) Red handle pointing right
3.
Connect other end of the hose to the pressurized fresh
water source.
4.
Turn ON the pressurized water source.
Water should now be available to all fixtures.
5.
To disconnect: Turn off water at the pressurized source first, disconnect hose from the
water source, (to release pressure off the system) then disconnect the hose at the city water
connection on utility center last.
"WINTERIZE" (plumbing lines and fixtures via pump)
NOTE: For complete winterizing instructions refer to the
Winterizing the Plumbing System section.
1.
Connect a garden hose to the city water inlet (do not use your fresh water hose to
winterize the water lines).
2.
Set the color coded valves to the WINTERIZE setting:
(A) White handle pointing right
(B) Blue handle pointing left
(C) Green handle pointing left
(D) Red handle pointing right
The water heater is bypassed automatically on this setting.
3.
Insert the other end of the hose in a container holding RV antifreeze.
4.
Turn the pump switch ON.
Antifreeze should begin flowing into the plumbing lines and fixtures (the pump will
5.
run when a faucet or the toilet is in use). To aid in siphoning place the container on a
surface approximately (2) feet off the ground.
Open one plumbing fixture, keeping it open until antifreeze appears then close it.
6.
Repeat for each plumbing fixture (including the outside shower hot & cold lines).
Turn the pump OFF when all fixtures have been winterized.
7.
8.
Disconnect the hose from the city water connection inlet (it is normal for some
antifreeze to exit the inlet hose as it is being disconnected).
