4. Use the level display on the monitor panel to
oversee filling of the tank, or when the tank is
full, water will flow from tank vent tube
beneath motorhome.
5. Turn OFF city water supply and disconnect
from the Fresh Water Inlet.
6. Turn Fresh Water valve to Normal position to
use the water pump.
The Tank Fill position is
only for pressure filling the water tank from
the city water hose connection.
Using City Water
When connected to an outside source of water,
the water bypasses the water pump and storage
tank and supplies pressure directly to individual
faucets and toilet. A check valve built into the
pump prevents water from entering the pump and
filling the storage tank.
1. Connect hose to Fresh Water Inlet as
described in previous steps.
2. With the Fresh Water valve in the Normal
position, turn the Water Pump switch(es)
OFF.
NOTE: Always keep the Fresh Water valve in
Normal position unless you are filling the
tank. If this valve is left in the Tank Fill
position while using the city water, water
will keep flowing into the tank and out
the tank vent tube onto the ground and
the water pump will run without
delivering water to faucets.
Disconnecting from City Water
1. Turn the city water supply OFF.
2. Open a faucet on the motorhome (such as the
exterior wash station, if equipped) to relieve
line pressure.
3. Disconnect hose from the motorhome and
replace the cap on the Fresh Water Inlet.
NOTE: Ensure the Fresh Water valve is in
NORMAL position to use the water
pump. If the valve is in Tank Fill
position, the pump will run continuously
without delivering water.
WATER PUMP
When your motorhome is not connected to a
city water supply, water is supplied from the
fresh water tank by a water system demand
pump. A demand pump is designed to run only
when you are using water. When you open a
faucet, the waterline pressure drops and the pump
begins to run, and it will continue to run as long
as the faucet is open. When you close the faucet,
the line pressure backs up to the pump, and it
shuts itself off.
The pump is self-priming and will run briefly
to build up line pressure when the Water Pump
switch is first turned on. See “Initial Waterline
Priming” for instructions on using the water
system for the first time.
Water Pump Strainer
The pump is equipped with a cleanable
strainer to capture any possible tank-borne
particles that could damage pump components.
NOTE: We recommend that you check and clean
the strainer after each tankful of water
during the first few uses of the Water
NOTICE
Do not leave fresh water connection
unattended when filling tank. Failure to
comply may result in tank expansion and
property damage.
