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 condi-
tion.
The LEDs on the panel indicate the following:
C = C harge at 12.7 volts
G = G ood at 12.1 volts
F = F air at 11.6 volts
L = L ow at 6.0 volts
Tank monitors on the touch screen have
a constant readout. There are no but-
tons to push. Tank levels are displayed
by percentage from 0% to FULL.
The
water pump switch (if so
equipped) may be located on the moni-
tor panel, the utility center, or both. On
certain RVs the water pump control may be on one of the selectable screens for the touch
screen.
When the water pump switch is ON (lit), 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.
Water heater switch(s) (if so equipped) are located on the monitor panel, or in the case of a
touch screen system, on one of the selectable screens of the touch screen. Switches 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.
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).
