WINTERIZING PROCEDURE
1. Clean and dump holding tanks by following

A.
Add water to the sewage holding tank
by holding the toilet flush lever open
with the water pump running. Add
water to the waste water holding tanks
by opening the kitchen, shower and lav-
atory faucets. Tanks should be about 1/
4 to 1/3 full to rinse properly. Driving to
a disposal site will normally loosen and
rinse any waste material from the sides
of the tank.
B.
Completely drain the sewage and waste
water holding tanks at an approved
waste disposal site. Drain the sewage
tank first so the following waste water
can rinse any waste solids from the
dump outlet and sewer hose.

Close dump valves and refit the dust cap
onto the drain outlet.
