KEY SYSTEM COMPONENTS
Vacuum Toilet: The VacuFlush toilet operates in a way different from
other marine toilets. VacuFlush systems use a small amount of water (a
little more than a pint) 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. VacuFlush toilets are equipped
with an integral vacuum breaker which prevents the possible contamination
of the potable water supply.
Vacuum Generator: The vacuum generator combines a vacuum tank and
vacuum pump in one unit. It greatly reduces installation time and elimi-
nates the hose run between the tank and pump. Its compact size makes
it especially well-suited to smaller crafts.
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. In a properly operating
system, the stored vacuum will leak down between flushes, causing the
vacuum pump to run for a short period.
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 12VDC. This unique pump design is both an efficient air
and liquid pump, and handles solids without a problem. It has two duckbill
valves on each side of the pump chamber.
Vacuum Holding Tank: A vacuum holding tank combines the vacuum tank,
vacuum pump and holding tank. Refer to the Vacuum Holding Tank Owner’s
Manual (part no. 600343026) for installation and other information.
