When traveling, you may want to drain the tank, or keep the quantity of water in it to a
minimum. This reduces the total weight of the motorhome for travel. Make sure when
draining the tank, that the water pump has been turned off. The fresh water tank drain
valve is located below and near the fresh water fill spout. Water in the tank can be
drained by turning the drain cock perpendicular to the motorhome body. To close the
valve, turn the lever parallel to the motorhome body.
Note:
Always fill the tank with clean potable water from a
known safe source. Make sure to close the fill spout when
the tank is filled.
To fill the fresh water tank:
1.
Remove the water fill spout cap and fill directly to the tank.
2.
Use a clean hose or bucket from a clean, safe source of water.
3.
Be sure to replace the fill spout cap after the tank is filled.
Note:
Never leave the hose unattended while you are filling the fresh
water tank.
Note: Water will overflow through the vent located at the top of
the fresh water tank if the tank is filled beyond capacity.
The handle should remain in the local supply position until you are ready to fill the
fresh water tank.
To fill a fresh water tank:
1.
Attach a potable water hose to the inlet inside the water
systems panel area, and an outside water supply.
2.
Turn the lever on the valve to the fresh water tank position
and begin filling.
3.
When the tank is full turn off the water supply. View reading on
the monitor panel.
4.
Return the handle to the local supply position.
Note:
Never leave the hose unattended while you are filling the
fresh water tank.
Note:
There is an overflow vent located at the top of the fresh
water tank. If the tank is filled beyond capacity water will
flow out through this vent onto the ground.
When using water from the fresh water tank, the system must be pressurized. A self-
priming 12V DC pump is provided to handle this function. A pump ON/OFF switch is
located on the monitor panel.
When initially starting up the self contained water system, follow this
procedure:
1.
Make sure the tank is filled with water.
2.
Open all the faucets in the motorhome, both hot and cold.
