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 .
