Section 8: Plumbing System
Operation
Press only one tact switch at a time. As you push either the
FRESH, BLK GREY1 or GREY2 switch, one or more LED
lights will illuminate (from left to right) indicating the
content level for that tank. When pushing the "BATT"
switch, the LED lights illuminate from left (lowest) to right
(highest) to indicate the estimated auxiliary battery
condition.
NOTE:When using shore power
all 4 LEDs will light. If disconnected
from shore power, 3 LEDs will light
to indicate a full charge (4th LED
may blink).
The LEDs on the panel indicate the following:
C
= Charge at 12.7 volts
G
= Good at 12.1 volts
F
= Fair at 11.6 volts
L
= Low at 6.0 volts
The water pump switch (if so equipped) may be located on the monitor panel, the utility
center or both. When the water pump switch is ON (it will light up), the water pump will run
until it reaches 45 lbs. of pressure. It will recycle when pressure drops. Turn the switch OFF
when the water pump is not being used.
The water heater switch(s) (if so equipped) are located on the monitor panel, and will light
up when turned on. The "LP GAS" water heater switch (12V) enables propane operation of
the water heater, and the "ELECTRIC switch (120V) enables electric operation of the water
heater. Normally both switches should be turned on to provide the fastest hot water recovery
time. The water heater can be operated in electric only or gas only modes by pressing each
switch independently. If the RV is equipped with a tankless water heater, there will be only
an LP Gas switch on the command center panel.
DSI FLT - Direct Spark Ignition Fault (if so equipped): This light located between the
water heater switches will indicate a problem with the LP portion of the water heater. When
the LP GAS switch is turned on, the light will blink quickly 3 times and the water heater will
ignite. The light will then remain off. If the light comes on and stays on, it indicates the gas
side of the water heater has not fired and there is a problem with the igniter.
