Dometic Freshwater Tank Monitor Installation
6.3 Probe Cap (fig . 3 B, page 2)
Caution!
Do not install probe cap in fuel tank. Never install Dometic probe cap with float switches
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 (fig . 3 B 4, page 3) down until the float
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
shoulder of the float, or the letters “NO”, should be facing down (B 5).
2 . Remove probe cap from tank and adjust the “2” probe (fig . 3 B 6, page 3) for one-half full level
for freshwater tank. Tighten the compression nut and cut the probe tube off 10 mm (0.375 inch)
above the compression nut without damaging the wires . Slip the black wire cover onto the top of
the tube. The recessed shoulder of the float, or the letters “NO”, should be facing down (B 7).
3. Route 18-gauge stranded copper wires from monitor panel and DC ground source to the probe
cap. Use quick-disconnect terminals on float switch wires to prevent twisting wires when remov-
ing the cap . With cap removed from tank, connect the wires according to the wiring diagram
(fig .
4 , page 3), turn on electrical power to system, and test the floats by moving them up and
down and monitoring the DTMF04 panel. Disconnect the wires and install the probe cap and
O-ring into the tank . Reconnect the wires .
