Caution! Safety Instruction: Failure to observe this instruction can cause material damage and impair the function of the device.

Table of contents 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.8 Dometic Tank Monitor SystemIntended use System Voltage Amp 12 V DC without shut-down relay with shut-down relay

“Power on” indicator. One Tank Monitor panel light is always lit to assure system operation. Long-lasting, foul-proof tank probes. Semi-exible probe stems move with tank contents to reduce stress. Integral sensor delay prevents false readings. Probe cap fits Dometic DHT-L series holding tanks. Also ts other tanks equipped with 76 mm (3 in.) NPT opening in top of tank. For holding tanks up to 56 cm (22 in.) deep. Flexible probes can be adjusted to t many tank sizes. 12 or 24 V DC operation.

5.2 Electrical Current Draw

Panel frame and mounting frame: ABS Panel surface: Polycarbonate resin Circuit breaker or fuse required for DTM04 panel: 1 amp Maximum shut-down relay rating for 12 or 24 V DC toilet system: 30 amps Probe cap: PVC Floats: Nitrile rubber ebonite9

1. Select panel location away from direct contact with water

2. Conrm clearance for wire connections behind wall, hull liner

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

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.

1. Heavy line indicates 14 gauge or larger stranded

copper wire is required.

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

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.

Dometic Tank Monitor System Operation

7.2 OPTION 2: DTM04 tank monitor system with “full tank” shut-down relay

1. When the Dometic Tank Monitor panel reads “Full” (4), electrical power to the toilet system will be

automatically turned off to prevent possible overlling of the holding tank.

2. Electrical power is restored to the toilet system when the “Full” level indicator light turns off during

light of the Dometic Tank Monitor indicator panel is on.

2. When holding tank contents rises above the lowest level oat switch (2), but is below the middle level

oat switch, the yellow “Low” light turns on, and the “Empty” light turns off.

3. When holding tank contents rises above the middle level oat (3), but is below the high level oat

switch, the amber “Mid” light turns on, and the “Low” light turns off.

4. When holding tank contents rises to the high level oat (4), the amber “Full” light turns on, indicating

that it is time to pump-out the holding tank. The toilet system should not be used until the holding tank is pumped out to avoid potential damage that may occur due to overlling the holding tank.
