2. Other wire can be 18 gauge stranded copper wire

or larger.

Caution!

Operator must know local regulations for emptying a holding tank.

Caution!

Do not install probe cap in fuel tank. NeverinstallDometicprobecapwithoatswitches

into a tank that contains anything other than waste water, grey water or fresh water.

6.3 Probe Cap (g.3B,page2)

1. Loosen compression nuts on adjustable probes and install probe cap into tank. Following

the top of the nut. Do not cut the probe tube at this mark. Loosen the compression nut, slide

theprobeup,andcarefullycutthe“1”probetube42mm(1.625inches)belowthemarkwithout

damaging the wires inside the tube. Pull the wires through the black wire cover and push the

probe down into the compression nut until the black wire cover touches the compression nut.
