7.1 Vacuum status monitor (in VacuFlush system)
WhenelectricalpowertotoiletsystemisturnedONandtheDNFpanelred light glows, this indicates
thatthereisNOTsufcientvacuuminthesystemtoushthetoilet.Do not flush toilet, or blockage
may occur.
Notes

betweenushes,thereisapossiblevacuumleakinthesystem.(AnidleVacuFlushsystem
should not cycle more frequently than once every three hours.)
If red light is OFF but there is no vacuum in system, a blockage has likely occurred
betweenthetoiletandvacuumtank.Openush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DNFisconnectedtoa“full”tanklevelsensororshut-downrelay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 (in VacuFlush system)
Whenelectricalpowertotoiletsystem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.
