SYSTEMS MONITOR PANEL

The systems monitor panel incorporates controls for
the water and holding tank levels, battery condition
and water pump. It may also control the water heater.

WATER PUMP CONTROL SWITCH

This rocker switch controls the demand water pump.
The water pump is pressure sensitive and starts (with
the switch ON) when a faucet is open, causing pres-
sure in the line to drop. When the faucet is closed,
pressure builds in the line and the pump stops.

MONITOR PANEL - LEVEL INDICATOR SWITCH(S)

When depressing the monitor switch, indicator lights
for the black (waste), grey (sink), fresh water tank and
battery condition will illuminate, indicating the existing
condition of each component.

Erroneous indications when checking water levels
can be caused by water with low mineral content.
Level is measured by a very low electrical signal
traveling through the liquid. Some water that is low
in mineral content may not conduct the signal prop-
erly. This condition may be infrequent, but can exist.
Check the panel reading when the fresh water tank
is filled. Material trapped on the sides of the holding
tanks may give a full reading when the tank is actually
empty. Use of a spray to wash out the tank following
dumping should help prevent this condition.

NOTE:

If the sensor probes mounted in the tanks get

coated with grease, the monitor panel may indicate
falsely or not at all. Avoid pouring grease, oils, or
similar substances down drains or the toilet. If this is
unavoidable, the holding tank(s) should be washed
out with a soapy water solution.

WATER HEATER IGNITION SWITCH

Your trailer may be equipped with a dual power (pro-
pane/120 volt) water heater with direct spark ignition
(DSI). It will have a DSI switch to ignite the propane
heater and a 120 volt switch to turn on the electric
heating element in the water heater.

INTERIOR FUSE PANEL

A 12-volt interior fuse panel is installed in the Power
Distribution Center to protect the interior circuits.
Circuit titles and fuse sizes are marked inside the
access door. If a fuse blows, locate and correct the
cause. Turn off all lights and motors, and then install
a fuse with the same rating. If fuses continue to blow,
a short circuit is indicated. Have the system checked
by qualified personnel.

FUSES

All the electrical circuits in your trailer have fuses to
protect them from short or overload. If something
electrical in your trailer stops working, the first thing
you should check for is a blown fuse. Determine from
the chart or the diagram on the fuse panel, which
fuse or fuses control that component. Check those
fuses first, but check all fuses before deciding that a
blown fuse is not the cause. Replace any fuses and
check the component’s operation.

Do not install fuses with amperage ratings greater
than that specified on the label. Replacing a fuse with
one that has a higher rating greatly increases the
chances of damaging the electrical system. If you do
not have a replacement fuse with the proper rating for
the circuit, install one with a lower rating until you can
replace it with the proper rated fuse.

If the replacement fuse of the same rating blows in
a short time, there is probably an electrical problem
with your trailer. Leave the blown fuse in that circuit
and have your trailer checked by your Lance dealer.

INTERIOR LIGHTING

The interior lighting operates on 12-volt DC power
only. When connected to a 120-volt source or us-
ing the generator, the power converter transforms
120-volts to 12-volts. However; when not connected
to 120-volts, the entire load of lights, water pump,
exhaust fans, etc., is on your 12-volt battery(s). Use
conservatively to minimize battery discharging.
