Plumbing Systems
Operation
Press only one switch at a time:
1. As you push either the “FRESH”, “BLCK,” “GRY1” or
“GRY2” switch, one or more LED lights will illuminate
indicating that holding tank content level.
2. When pushing the “BAT” switch, the highest LED light
illuminated indicates the estimated auxiliary battery
condition.
Water pump switch
When the water pump switch is ON the water pump runs until
45 pounds of pressure has been achieved. The red light will
stay ON. Turn the water pump switch OFF when it is not in
use.
Water heater switch
The "GAS" water heater switch enables propane operation of
the water heater. The "ELECTRIC" water heater switch en-
ables electric operation of the water heater.
FRESH WATER HOLDING TANK
The fresh water tank can be pressure filled using the fresh
water inlet or gravity filled using the gravity fill inlet. Plastic
overflow tubes are plumbed into the fresh water holding tank
to allow water to flow out of the water tank. Occasionally, you
may see water coming from the overflow tubes (located un-
derneath the RV) when the fresh water holding tank is filled.
This is normal, and is caused by external circumstances,
including the RV being parked on an incline, or the motion
caused by starting or stopping the RV during travel.
Do not cap, block or modify the fresh water tank overflow
tubes in any way. Enough water pressure can build up during
the filling process to damage the plumbing system if the over-
flow tubes are obstructed.
WATER PRESSURE REGULATOR (CUSTOMER SUPPLIED)
Excessive pressure from water supply systems may be en-
countered in some parks, especially in mountain regions. Wa-
ter pressure regulators can protect your system against such
high pressure. Water pressure regulators are available for
purchase from your RV dealer to protect the plumbing system
against such high pressure.
