Triple E 1999 Class C - FRESH WATER TANK FILLING PROCEDURE

CLASS C MOTORHOME
12.1.1 FRESH WATER TANK FILLING PROCEDUR E
The water tank is not a pressure vessel. The
filling procedure is done via a water pressure
system and cannot be done without available
water under pressure. Make sure the vent/
overflow drain located underneath the tank area is
open, free and clear of any obstruction before
attempting to fill the tank. A blocked vent during
filling could cause serious damage to the tank and
even the underfloor structures.
When filling fresh water tank:
1. City Water Supply:
a. Connect water hose to the city water inlet
connection.
b. Set pump switch, for the motorhome
system, to the off position.
c. Open source of water supply valve.
d. Check the Monitor System inside the
motorhome for levels as the tank is filling.
When the tank is close to full, check for
overflow at the above-mentioned drain.
e. Turn the supply off as soon as water flows
from the drain.
f. Turn pump switch back on and the sys-
tem is ready to be used.

2. Non-Pressurized Water Supply:
a. Set pump switch to the off position.

IMPORTANT
If you are starting from a dry system
or if some faucets have been open
during the tank filling procedure, you
may want to slowly open all faucets
one at a time to allow any trapped air
to escape from the system.
