WATER SYSTEMS — 6
The water pump can be off or on. It does
not affect the water pump to leave it on.
CAUTION:
Some outside water sources develop
high water pressure, particularly in
mountainous regions. High water
pressure is anything over 55 psi (pounds
per square inch). Excessive water pressure
may cause leaks in water lines and/or
damage the water heater. An additional
pressure regulator can be connected to the
city water faucet to regulate the pressure
to the potable water hose. Excess pressure
on a hot day can cause the water hose to
swell and burst.
NOTE:
When connecting the motorhome
to fresh water be sure to use a hose
manufactured and labeled for potable
water to ensure that the hose will not
flavor the water.
Fresh Water Tank Fill
Connect a potable water hose to the
City/Fresh water hook-up located in
the service center on the roadside of the
motorhome.
Place the AutoFill/
City Water switch
in the
up
position
to engage the
fresh tank auto-
fi
ll feature. A
valve behind the
plumbing manifold
will automatically
shut off the
incoming water
supply when the fresh
tank is 98% full.
Turn the motorhome water pump on
(switches located in service center, galley
and bathroom) to access water from the
fresh water tank. When the water level in
the fresh water tank is depleted to 80%,
the valve will automatically open and
re
fi
ll the tank to 98%.
NOTE:
Cycle the AutoFill/City Water switch to
fill the fresh water tank at any time.
NOTE:
If the tank fails to fill while in Automatic
Fill mode (perhaps because an external
water valve is inadvertently shut), the fill
solenoid valve will deactivate after one
minute to prevent heat damage.
HOSE REEL (Optional)
The water hose reel eliminates the need to
store a potable water hose in the bay. Use the
hose reel for city water hook-up or to
fi
ll the
fresh water tank. The reel is equipped with
a 35' hose and a 12 Volt DC motor that will
retract the hose after use. The water reel is
located in the service bay.
City Hook-Up
Remove hose plug and install a water
pressure regulator to the water hose.
Pull hose from reel and connect the
water hose to a City Water hook-up.
Place the AutoFill/City
Water switch in the
down
position.
Turn on the water
supply.
