FRESH WATER SYSTE M
GENERA L
Fresh water for your unit is supplied either b y
the vehicle's fresh water tank or an external pres-
surized source . Both supply water to the kitche n
sink, tub/shower, lavatory, toilet and water heater .
WATER TAN K
Unlock the door to expose the gravity water fil l
(Figure 6) . Use a hose or vessel to fill the water tank .
Water will flow out the fill opening when the tan
k
is full .
WATER PUM P
Your water pump is a 12-volt DC appliance ,
activated by a switch on the Monitoring Panel . Yo u
may leave the switch ON while camping . This arrange -
ment is known as a demand system . When you want
water, simply open a faucet ; the pump will run onl y
as long as needed . If the pump fails to start whe n
the switch is ON, check the fuse located in th e
fuse panel . If the pump continues to operate, whethe r
the faucets are opened or closed, check the wate r
tank, it is probably empty .
SANITIZING WATER TAN K
Sanitize your unit's water tank before initia l
use, after a period of nonuse, and whenever th
e
tank is suspected of being contaminated . Open th
e
water tank drain valve . When the tank is empty ,
close the valve . Mix 3 gallons of water with 3/4 cu p
liquid household bleach . Pour the solution into th e
tank through the gravity fill . Wait 3 hours, drain an d
flush with fresh, potable water . If chlorine tast e
lingers, pour 1 quart of vinegar and 5 gallons of wate r
into the tank
. Wait several days before drainin g
water
. Flush tank with fresh, potable water
.
CITY WATE
R
Connect a hose to a "city" pressurized wate r
faucet and to the vehicle's water inlet (Figure 7) .
When using the city water hookup, the water tan k
and pump are bypassed . You cannot fill the wate r
tank through the city water inlet .
Although a common garden hose can be use d
to fill water tanks and to connect to city water ,
longtime RV'ers recommend a hose specificall y
manufactured for this purpose .
CAUTION : In areas where city water pressur
e
exceeds 60 psi, you should use a pressur
e
regulator . Excessive water pressure may damag
e
lines and connections
. See your GMC deale r
for further details .
WATER PURIFIE R
The optional water purifier is designed to provid e
clear, good-tasting, bacteria-free drinking water . I t
is connected to the cold water line below the sin k
and attached to a special faucet on the sink ledge .
Push down on the lever for a restricted flow of wate r
or lift the lever for an unrestricted, continuous flow .
See the manufacturer's instruction booklet fo r
backflushing the purifier element and maintenance .
