SANITATIoN SYSTem CompoNeNTS
Vacuum Toilet: VacuFlush all-ceramic vacuum toilets with
Flush and Forget ® technology operate differently compared
to other toilets. The vacuum system uses a small amount of
water (a little more than a pint or .5 liter) per flush in addition
to a simple vacuum. The toilet is connected to a pressurized
freshwater system. Fresh water is the key to an odor-free
bathroom compartment. Most VacuFlush toilets are
equipped with an integral vacuum breaker which prevents
the possible contamination of the freshwater supply.
Flush/Add Water Switches (3100, 3400 models only):
Wall-mounted push-button switches provide electronic
operation of flushing and adding water to the toilet bowl.
Models include two-light vacuum status panel indicating the
toilet is “OK to Flush” or “Do Not Flush”. Models vary.
Vacuum Generator: The vacuum generator combines
the vacuum tank and vacuum pump in one unit. It greatly
reduces installation time and eliminates the hose run
between the tank and pump. Their compact size makes them
especially well-suited to smaller installation spaces.
Vacuum Tank: The vacuum tank stores vacuum energy.
System vacuum level is monitored by a vacuum switch
located on the vacuum tank. When this switch senses
a drop in vacuum in the system, it automatically signals
the pump to energize and bring the vacuum to operating
level. This process is normally completed in less than one
minute.
Vacuum Pump: The vacuum pump is an electric,
straight-through bellows type. It is manufactured of long-
lasting polypropylene and draws only 4 to 6 amps of current
at 12 VDC. This unique pump design is both an efficient air
and liquid pump that handles solids without a problem. It
has two duckbill valves on each side of the pump chamber
to maintain vacuum and prevent backflow of waste.
“Tank Full” Shut-Down Switches (RV option only):
These “Tank Full” micro-float switches shut down the
vacuum generator when the waste holding tank is full.
We offer three styles to accommodate various installation
requirements.
Sealing grommet style – Item number 900101
MPT style – Item number 900100
Vent style – Item number 900102
(NOTE: Requires relay mounted on vacuum generator.)
