I did the install of the Seelevel II-P3. Here are my notes and observations. I will add photos later when I get back out to the trailer. I orderd two of the 710-JS 6" sensors as the one side of the tank available on the Gray & Black were 4". I also ordered 1 12″ 710-ES for the Fresh water tank.
- The hole in the wall for monitor panel must be enlarged due to back of monitor being slightly larger. The Monitor panel will cover the rough hole if you don't make it too large.
- Wiring for pump switch on the monitor panel ( the wire in the wall matches up):
white - top of switch
violet - middle of switch
red bottom of switch.
3. Wiring for monitor:
Wires in Wall - Monitor Panel
Red - Red
White (ground) - Black
Grey, Brown, & Blue (tank wires) - Blue
Unknown or Unused - White (Tank Ind)
4. Tanks are located as follows:
Fresh water - inside under left closet (panel unscrews).
Black tank - Under the back in front of the trailer skids.
Grey - Under the back in front of the Black tank.
5. All wires from the tanks must be connected ( I don't know why, this was the only way it worked) - Orange, Green, Yellow to the Blue sensor wire. White to the Black ground sensor wire on the sensor.
I would recommend putting the Black & Grey sensors on the opposite side of the tank (door side) as there is a bigger area for the sensor. Extra wire would be needed to run to old tank wiring.
