Water Pump Switch
The Water Pump switch provides power to the water pump for times when the coach is not connected
to city water. The water pump pulls water from the fresh water holding tank and pumps it through the
plumbing using the same lines that city water follows. The pump has a pressure sensor that detects the
drop in pressure that occurs when a faucet is opened. If the pump has 12V DC power, when the
pressure drops, the pump begins pumping water. When you close the faucet, pumping continues for a
short time until the pressure sensor detects that normal pressure has been restored in the lines.
Note that when using fresh tank water, in addition to having the pump turned ON, the 4-way Anderson
Valve in the Universal Docking Center (UDC) must be set to NORMAL. This setting enables water from
the fresh tank to flow through the 4-way valve to the faucets and other fixtures. If not in NORMAL
mode, the pump will run for a short time but no water will come through the faucets.
When using city water, it’s a good practice to leave the Water Pump switch OFF. It’s also a good
practice to leave the switch OFF when towing and when leaving the coach for long periods.
Note that pets have been known to jump onto kitchen counters and rub against the faucet controls,
turning water on. If you leave the pump turned on with gray tank valves closed, you could return to find
the interior of your RV flooded.
Awning Switches
The Awning switch extends or retracts the main patio awning. The Awning Light switch turns on the LED
strip mounted on the coach sidewall, along the awning. With the optional exterior TV, a separate patio
awning is provided for the TV area outside the coach. A separate awning switch for the TV awning is
usually located inside, near the entrance door.
Awning Receptacle Switch
The Awning Receptacle switch turns on 120V AC power to an exterior outlet located near the front of
the main awning. This allows you to hang lights on the awning or nearby and turn them on and off
without going outside.
Inverter Remote Switch
When towing, your batteries supply power to an inverter that converts 12V DC into 120V AC to power
the Residential Refrigerator. Any time that 12V power is turned off, either by removing batteries for
service or when in storage, or by turning the battery cutoff switch(es) to OFF, the inverter will turn off
and stay off when power is reconnected. The remote switch may be used to turn the inverter ON,
provided the battery cutoff switches are ON.
CAUTION:
If you hear the water pump running when faucets are closed, it’s critical to find the cause
without delay. While it could be due to a malfunctioning pressure switch, it’s more likely there is a
water leak somewhere in the plumbing system. If not corrected, water leaks can lead to extensive
damage. If you are unable to resolve the problem, the pump switch should be turned OFF to prevent
damage to your coach.
