Inaccurate Holding Tank Level Readings:
The accuracy of two wire holding tank monitoring systems can be adversely affected by dirty
tanks, unusual mineral content in the water, or improper holding tank probe location. These
conditions can cause the monitoring system to have oversensitive (read higher than actual
level) or under sensitive (read lower than actual level) readings.
Oversensitive Readings:
To correct this problem, the holding tanks should be cleaned periodically (consult dealer for
cleaning instructions). If the problem persists after cleaning the holding tank, the ground probe
can be moved farther away from the other tank probes. The increased distance between the
ground probe and the other probes will decrease the sensitivity of the monitoring systems.
Under Sensitive Readings:
This problem can be corrected by moving the ground probe closer to the other probes. Moving
the ground probe closer increases the sensitivity of the monitoring system.
Water Pump:
Turns the water pump ON or OFF (Refer to the “ Water Pump ” section under the heading
“Fresh Water System” for more information).
Level Test:
Press and hold to check tank levels as well as the LP Gas (Propane) level.
Water Heater LP Gas:
Switches the water heater to the LP Gas (Propane) mode.
Water Heater 120 Volt:
Switches water heater to 120 Volt A/C mode.
NOTE: The red indicator light between the two switches will illuminate when the water heater
has failed to ignite after three attempts. The water heater will then go into a lock-out state.
Turn the switch to the OFF position and the water heater will reset automatically.
Coach Disconnect:
Connects or disconnects house batteries during usage or storage.
Slideouts:
Slideout #1 operates the main living room slideout and Slideout #2 operates the kitchen
slideout.
NOTE: For more information regarding the proper use of the slideout switches refer to the
“Slideouts” section of this manual.
