MONITOR PANEL
The monitor panel allows you to quickly check the levels in the fresh water and waste water tanks. Electrical
sensors at various points on the tanks send signals to the monitor panel. To check fluid levels, press and hold
the test switch designated for the tanks, and read the level indicators on the panel. The indicator is proportioned
in thirds with each light being lit up to the level that the tank contains.
Sometimes, residue on the sides of a tank, or water with a low mineral content will give a false reading. Check
the levels occasionally when you are sure of a tank’s contents to double check the accuracy of the monitor
panel.
Tank Capacities
The monitor panel allows you to quickly check the levels in
the fresh water and waste water tanks. Electrical sensors at
various points on the tanks send signals to the monitor panel.
To check fluid levels, press and hold the test switch designated
for the tanks, and read the level indicators on the panel. The
indicator is proportioned in thirds with each indicator light
illuminating to the level that the tank contains. Indicator lights
and their meanings:
Inaccurate holding Tank Level readings
The accuracy of two wire holding tank monitoring systems can be adversely affected by dirty tanks or unusual
mineral content in the water. These conditions can cause the monitoring system to have oversensitive (reads
higher than actual level) or under sensitive (reads lower than actual level) readings.
over Sensitive readings
Oversensitive readings can occur as a result of scum build up on the tank walls, or abnormally high mineral
content in the water. In these situations, the monitoring system indicates higher levels than are actually present
in the holding tank. Certain cleaning products and food by-products can build up on the inside walls of the
holding tanks, producing a layer of scum that can cause the monitoring system to read higher than the actual
level. To correct this problem, the holding tanks should be cleaned periodically (consult dealer for cleaning
instructions).
Under Sensitive readings
Under sensitive readings can occur if the mineral content of the water is abnormally low. In this case, the
monitoring system indicates lower levels than are actually present in the holding tank. This problem can be
corrected by moving the ground probe closer to the other probes.
WASTE WATER SYSTEM
The waste water system in the motor home can be described as two separate systems. A gray water system
that consists of the drain lines and holding tank for waste water from the sinks and tub, and a black water
system which includes the holding tank and drain for toilet wastes. In some cases the bathroom lavatory may
drain into the black tank to make sure there is adequate water to prevent solid build up. Each system is self-
contained, and allows disposal of waste water at designated dump stations at your convenience.
Components of the gray water system have drain traps, and both tanks are vented to equalize air pressure
and disperse odors caused by drain water and wastes outside. Sometimes, the rocking movement of the motor
home while driving may empty the drain traps of their water, and allow the odors of the gray water tank to come
into the coach. Residue in the drain water lines can also produce odors. To combat gray water holding tank
odors, an approved deodorizing agent should be used. An agent that dissolves grease and fats and contains
a detergent will help keep tank and drain lines clean and free-flowing.
