KEY SYSTEM COMPONENTS (cont'd)
SaniGard Holding Tank Vent Filter: The vent
filter stops odors that escape from the holding tank
vent. It contains odor-removing filter media to keep
your boat smelling clean and pleasant. Each cartridge
is good for an entire season and is easily replaced for
a fresh start.
"Tank Full" Float Switch: The Tank Full Float Switch is mounted in top of the
holding tank or vent pipe, and shuts the vacuum pump or vacuum generator off when
the float switch is activated by the rising contents of the holding tank. This relay also
sends a signal to the status panel red light. This relay is prewired and mounted to the
pump on the vacuum generator. For systems using a vacuum tank and separate
pump, it is mounted separately during installation and wired accordingly.
SaniPump™ Discharge Pump: For thorough, trouble-free holding tank
pump-out, our discharge pump offers many benefits. Its specially designed bellows
diaphragm allows it to run dry without harm. It handles up to 315 gallons (1192
liters) per hour, while drawing only 6 amps at 12 volts DC.
NOTE: On/Off switch for discharge pump is supplied by installer.
Discharge Hose: Reinforced, 32 mm ID, 3-meter discharge hose. Includes
38 mm adapter to connect to discharge pump outlet.

IMPORTANT INFORMATION BEFORE OPERATION
SYSTEM START-UP
1. Turn on electrical power to sanitation system.
2. Flush water into system by depressing flush lever on toilet until water starts flowing through the vacuum pump and
into the holding tank (blackwater tank). This wets the pump interior for efficient operation. If the vacuum pump
does not run, check for loose electrical connections. Refer to the system Wiring Diagram.
3. The vacuum pump will run for approximately 30 to 90 seconds until the system reaches operating vacuum level
and then will shut off.
