CHAPTER 6 - INSTALLATION GUIDE
1. Please refer to the "Troubleshooting and Installation Tips"
section in Chapter 7 for details on avoiding installation issues.
2. The installation consists of mounting the display inside the RV,
cutting and fastening the senders to the sides of the holding
tanks, connecting wiring, and programming the display. When
wiring DO NOT use spade connectors to join wires, only use
crimp on butt connectors or solder the wires together.
3. Mount the display by cutting a hole in the wall 3" wide by 1
high and bringing the wiring out through the hole to connect
to the display panel connector.
4. Connect the wiring according to the following table. It is
easier to connect the wiring to the display connector first, and
then plug the connector into the display panel. The senders
need to be grounded to a single ground wire from the display.
Make sure that the system ground is connected to the breaker
panel ground.

5. Determine where to mount the senders on the tanks. They
will need to have a flat area on the side of the tank large
enough so the whole width of the sender is in contact with
the side of the tank, all the way from the top to the bottom of
the tank. Make sure that any metal is at least an 1" away from
either side or the top and bottom of the sender, and at least 2"
away from the face of the sender. Clean the area well so that
there is no dust, grease, oil, water, etc., that would prevent the
adhesive on the sender from sticking.
6. Measure the height of the tank to determine which sender
configuration to use and how long the senders should be.
Refer to the following table.
