Operation
To check tank capacities or battery condition, depress the corresponding button on the panel. In order to
obtain a true reading on the batteries, you must be unplugged from city power and disconnected from your
tow vehicle. Black is sewer and Gray is lavatory sink and kitchen water.
The range exhaust fan has an exterior door that must be unlatched to be effective. You'll see the two small
twist latches if you look at the fan from outside the motorhome. In most circumstances you can leave the
door unlatched. During storage or adverse weather conditions, latching the door is recommended.
Trouble Shooting Guide
Be sure the wiring to the panel is correct and that the house battery is well charged. All electrical
connections must be correct.
NOTE: RV's are subjected to a lot of vibration from traveling on the highways, so always look for broken
wires and loose or broken connections.
NOTE: If a RV has exposed holding tanks under the vehicle and the vehicle is operated in the rain, sleet or
snow, the panel may show incorrect tank levels due to electrical conductivity on the outside of the tanks.
Washing the tanks and sealing the connections on the outside of the well nuts with silicon sealer should
correct this condition.
When troubleshooting a problem with a Ventline monitor system, always remember that there are four
basic system components to consider.
1) The monitor panel assembly, which includes the circuit board, lights, and switching.
2) The wiring harness, which includes the wires and connectors that connect the monitor panel to 12-volt
DC power, ground, tank resistor harnesses, LP sensors and switching.
3) The tank resistor harness, which includes the wires, connectors, and encapsulated electronic components.
4) The holding tank sensors and fresh water probes.
In many cases a malfunction of one of the above components will be reflected in another, which can result
in misdiagnosis of the actual problem. Ventline recommends a consistent, methodical approach to
troubleshooting in order to diagnose and correct the problem with the minimum investment in time and
resources.
COMMON FIELD PROBLEMS
- Inaccurate Holding Tank Level Readings
- Some Or All Holding Tank Level Lights Not Coming On
- Some Or All Holding Tank Level Lights Continuously On - LP Gas Levels Not Reading Properly
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 (reads higher than actual level) or under sensitive (reads lower
than actual level) readings.
