Dometic Tank Monitor System Notes on using the manual
2 General safety instructions
The manufacturer will not be held liable for claims for damage resulting from the following:
• Faulty assembly or connection
• Damage to the unit from mechanical inuences, misuse or abuse
• Float switches fouled with tissue paper
• Alterations to the unit without express written permission from the manufacturer
• Use for purposes other than those described in this manual
3 Intended use
3.1 OPTION 1: DTM04 tank monitor system
DTM04 Tank Monitor System provides electronic monitoring of the liquid level inside a holding tank.
Three oat switches inside the tank activate a set of four lights on an indicator panel. The lights indicate
Empty, Low, Mid and Full levels. The Full level indicates when the liquid level is within 51 mm (2 in.) of
the top of the holding tank. The other oat switches are connected to adjustable probe stems which
can be positioned according to the tank height and the desired indicator panel readings.
3.2 OPTION 2: DTM04 tank monitor system with “full tank” shut-down relay
When the optional “Full Tank” Shut-down Relay (available separately) is connected to the DTM04 panel,
and the holding tank reaches the Full level, the relay shuts off power to the electric toilet. This prevents
use of the toilet and the possibility of overlling the holding tank. See Components for “Full Tank” Shut-
down Relay item numbers. The relay handles a maximum electrical current of 30 amps.

1. Select panel location away from direct contact with water
and oil.
2. Conrm clearance for wire connections behind wall, hull liner
or bulkhead.
3. Using control panel template (g. 8 , page 5), cut out
panel access hole (E, F) and drill fastener holes (G).
4. With electrical power off, route 18-gauge stranded copper
wire from power source, through circuit breaker or fuse (not
provided), to panel location. Route additional wire according
to diagram (g. 4 , page 3 – see wiring diagram key
below), depending on your application, to panel location.
Make sure wires extend out through access hole.
5. Make proper wiring connections to wires extending from
bottom of circuit panel (g. 3 A 2, page 3).
6. Remove panel cover (g. 3 A 1, page 3) from circuit panel/
mounting frame (A 2), if necessary, by carefully pulling them
apart.
7. Install mounting frame to wall with four fasteners (g. 3 A 3).
8. Push panel cover onto mounting frame until it locks into
place.
1. At step 4 (above), route and connect 14-gauge stranded copper wires according to wiring diagram
(g. 4 , page 3) and wiring diagram key (see below).
2. Insert “Full Tank” shut-down relay into receptacle on back of circuit panel.

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
numbers printed on top of probe cap, slide the “1” probe (g. 3 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 shoulder of the oat, or the letters “NO”, should be facing down (B 5).
2. Remove probe cap from tank and adjust the “2” probe (g. 3 B 6, page 3) for one-half full level
for black or gray water tanks. 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 oat, or the letters “NO”, should be facing
up (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 oat switch wires to prevent twisting wires when remov-
ing the cap. With cap removed from tank, connect the wires according to the wiring diagram
(g. 4 , page 3), turn on electrical power to system, and test the oats by moving them up and
down and monitoring the DTM04 panel. Disconnect the wires and install the probe cap and O-
ring into the tank. Reconnect the wires.
