EXTERNAL WATER SUPPLY
The external water source will supply
your motorhome water system with water
at city pressure when the water pump is
switched off.
1.
Connecting:
a.
Turn water pump switch to off.
b.
Attach garden hose to city water
connection. Turn the water
selector valve to city water.
c.
Turn on external water supply.
IMPORTANT
After connecting to the external
water supply, open the faucets in
your motorhome slowly and
cautiously. Air trapped in the line
can cause the water to splash
into the sink. You may want to
drape a wash cloth over the
faucet to prevent excessive
splashing.
IMPORTANT
Some campgrounds have an exces-
sively high water pressure which can
cause problems. It is a good idea to
get a pressure reducer from your RV
center and attach it to your incoming
external water supply hose to ensure
safe pressure for your unit.
3.
Disconnecting:
a.
Turn off the external water tap.
b.
Relieve water pressure on the line by
opening a faucet in the motorhome.
c.
Disconnect hose from the motorhome.
d.
Replace the protective plug back over the
water connection.

2.
Turn the water heater by-pass valves to
normal to be sure that water enters the
heater and hot water is available for
motorhome use.
Water from the external supply is pre-
vented from entering the water tank and
the water pump by means of a check-
valve.
