below:

valve BEFORE removing the water heater drain plug.
Otherwise, if there is any water pressure present the
water will spray out of the opening when the drain plug
is removed.

When you are finished draining the fresh water system re-
verse these steps, turn the water heater bypass valves back
to the normal camping use positions, and dump the grey and

in the fresh water tank after drainage procedure.
SANITIZING THE POTABLE WATER SYSTEM
To assure complete sanitation of your potable water system,
the following procedures are recommended for a new system,
for one that has not been used for a period of time, and for
one which may have become contaminated:
Prepare a chlorine solution using one (1) gallon of water and
one-quarter (1/4) cup of household bleach (5% sodium hy-
pochlorite solution). Prepare approximately one (1) gallon of
solution for each fifteen (15) gallons of holding tank capacity.
Note: as an option, several commercial solutions are avail-
able, and should be used as directed on the package.
To sanitize the fresh water system, including the fresh water
tank:
1. Pour the chlorine/water mixture into the gravity water fill
inlet.
2. Turn the water pump ON.
