7 Operation
7.1
Vacuum status monitor
(fig .

, page 2)
1. When power switch is turned ON, the
green light indicates that there is sufficient vacuum in the
VacuFlush system to flush the toilet (A).
2. When power switch is turned ON and the
red light glows, this indicates that there is NOT sufficient
vacuum in the system to flush the toilet (B). Do not flush toilet, or blockage may occur in system.
Notes 
If	green	and	red	light	constantly	cycle	on	and	off	between	flushes,	there	is	a	possible	
vacuum	leak	in	the	system.	(An	idle	VacuFlush	system	should	not	cycle	more	frequently	
than once every three hours .)
If green light is ON but there is no vacuum in system, a blockage has likely occurred 
between	the	toilet	and	vacuum	tank.	Open	flush	ball	in	toilet	bowl	and	use	standard	toilet	
plunger to unblock .
After a period of time, if red light seems to remain lit longer than when toilet system was 
new, duckbill valves in vacuum pump may require replacement .
Caution! 
If	DVS02	is	connected	to	a	“full	tank”	sensor	and	holding	tank	is	empty,	a	continuous	red	
light may indicate extensive vacuum loss due to blockage, pump failure or leak . Turn off 
vacuum system and repair as soon as possible.
7.2
“Full tank” monitor
(only when connected to “full tank” sensor in waste holding tank)
1. When power switch is turned ON, the red light glows, and the vacuum pump is not running, this
indicates that the holding tank is full and needs to be pumped out . Do not flush toilet, or blockage 
may occur in system. 
7.3
Circuit breaker control

, page 2)
1. Turn the power switch to the ON position (A, B) for normal toilet operation. One light will always be lit
to	indicate	there	is	power	to	the	VacuFlush	toilet	system.		Allow	system	vacuum	to	fully	recharge	and	
green light to illuminate before turning power OFF for any reason .
2. During the night or other extended periods when the toilet or vacuum system is not needed to
operate, turn the power switch to the OFF position (C).
