into a tank that contains anything other than fresh water, gray water or waste water.
1. Loosen compression nuts on adjustable probes and install probe cap into tank. Following num-
bers printed on top of probe cap, slide the “1” probe (g.

B4,page3)downuntiltheoat
touches the bottom of the tank. Tighten “1” compression nut and mark the probe tube at 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. The recessed
