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 influences, 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 float 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 float 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 overfilling the holding tank . See Components for “Full Tank” Shut-
down Relay item numbers . The relay handles a maximum electrical current of 30 amps .
