KEY SYSTEM COMPONENTS
VACUUM HOLDING TANK
SYSTEM
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 ush 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 eliminates 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 ushes, 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 efcient 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.

TOILET OPERATION
IMPORTANT INFORMATION BEFORE OPERATION
1. Fill freshwater tank and add deodorant to holding tank through toilet bowl.
(See System Start-Up section.)
2. Make sure all guests understand the operation of the VacuFlush system
and the instruction label is in plain sight and easy for guests to read. If
this label is not included in this manual, please contact the SeaLand
Product Customer Service Department immediately.
3. Remember the vacuum pump starts automatically. Shut off the system before servicing and do not leave
the boat with toilet system breaker on.
4. Never use drain openers, alcohol, solvents, etc. in the system.
5. If the system does not function properly, refer to the Troubleshooting section of this manual and repair as
necessary. If problem persists, contact your local SeaLand product dealer.
SYSTEM START-UP
1. Turn on electrical power to system.
2. Flush water into system by depressing ush lever until water starts owing to the vacuum pump, about
15 seconds. This wets the pump interior for efcient operation. If vacuum pump does not run, check for
loose electrical connections.
3. The vacuum pump will run for approximately 30 to 90 seconds until system reaches operating vacuum level
and then will shut off.
NORMAL OPERATION
1. To add water to the toilet before
using, raise flush lever until desired
water level is reached. Generally, more
water is required only when ushing
solids.
2. To flush toilet, press flush lever
sharply down to the oor. A sharp popping noise is normal when the vacuum
seal is broken. Hold lever down for
three (3) seconds. After ushing, let
ush lever snap back into original
position. If ush lever is accidentally
released before waste clears bowl, do
not attempt to ush toilet again until
vacuum pump stops running. A small
amount of water should remain in the
bowl after ushing.
3. Do not dispose of sanitary napkins
or other non-dissolving items in toilet,
such as facial tissue or paper towels.
These items can cause plugging of
the system.
NOTE: Make sure all guests understand the operation of the SeaLand toilet, and that the instruction label is
easy to read and in plain sight.
