1. Connect a garden hose to the city water inlet (do not use your fresh water hose to win-
terize the water lines).
2. Set the color coded valves to the WINTERIZE setting:
(A) White handle pointing down
(B) Blue handle pointing left
(C) Black handle pointing right
(D) Red handle pointing left
(E) Green handle pointing up
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.
5. Antifreeze should begin owing into the plumbing lines and xtures (the pump will run
when a faucet or the toilet is in use). To aid in siphoning place the container on a surface
approximately (2) feet o the ground.
6. Open one plumbing xture, keeping it open until antifreeze
appears then close it. Repeat for each plumbing xture (in-
cluding the outside shower hot & cold lines).
7. Turn BLUE, GREEN and WHITE handles so they are at a 45°
angle for 10 seconds.
8. Turn the pump OFF when all xtures have been winterized.
9. Return all handles to the WINTERIZE setting.
10. 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).
11. Leave the valves set on WINTERIZE setting.
When your RV is new.
At the beginning and end of each season.
When the water system becomes contaminated or every three months of use.
1. Turn water heater power OFF. Both switches
(electric & LP gas). Set the valves to
as indicated on the utility center label. Setting
these valves bypasses the water heater automati-
cally.
2. Level the recreational vehicle and drain the fresh
water system. (see Draining the Fresh Water Sys-
tem).
For winterizing instructions, refer to the Winterizing
the Plumbing System section.
