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 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 eliminates the hose run between the tank and pump. Its compact size makes
it especially well-suited to smaller crafts.
Model 148
VacuFlush
Toilet
Vacuum
Generators
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 Tank
and Pump
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.

TOILET MODEL IDENTIFICATION
The toilet model identification label is located on the toilet base and will show
the model number and serial number.
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 flush lever until water starts flowing to the vacuum pump, about
15 seconds. This wets the pump interior for efficient 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 flushing
solids.
2. To flush toilet, press flush lever
sharply down to the floor. A sharp popping noise is normal when the vacuum
seal is broken. Hold lever down for
three (3) seconds. After flushing, let
flush lever snap back into original
position. If flush lever is accidentally
released before waste clears bowl, do
not attempt to flush toilet again until
vacuum pump stops running. A small
amount of water should remain in the
bowl after flushing.
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.
4
PROPER TOILET CLEANING
To maintain the toilet’s original, lustrous appearance, use SeaLand® Toilet
Bowl Cleaner or other non-abrasive bathroom and toilet bowl cleaners.
Please follow label directions.
Fig. A
Caution
To avoid damaging the toilet system’s seals and valves,
do not clean toilet with abrasive cleaners, caustic chemicals, or lubricants and cleaners that contain alcohols or
petroleum distillates.
WINTERIZING
At the end of each season, the SeaLand toilet should be winterized for
Fig. B
storage, by either draining or using potable water-safe antifreeze in the
system.
To drain:
1. Thoroughly flush system with fresh water.
2. Empty holding tank.
3. Shut off water supply to toilet(s), and remove inlet waterline (Fig. B).
Do not remove cap on bottom of valve.
4. Press flush lever until all water is drained from toilet(s).
To use antifreeze:
1. Drain potable water tank.
2. Add freshwater antifreeze to potable water tank.
3. Flush potable water antifreeze and water mixture through toilet(s) and into the waste holding tank. Each
installation is different, so amounts may vary. User discretion is required to assure adequate protection.
4. Empty holding tank.
NOTE: Use nontoxic antifreeze designated for potable water systems. (See vehicle owner’s manual.)
CAUTION: Never use automotive-type antifreeze in freshwater systems.
CLEARING DISCHARGE LINES
Sanitation hoses should be cleared if toilet will not be needed for an extended period of time (more than two weeks).
1. Fill toilet bowl with water and add 4 oz. (120 ml) of biodegradable laundry detergent (should NOT contain bleach).
2. Flush toilet, holding pedal down for about two minutes. Close flush ball.
3. Turn off water supply to toilet.
4. Flush the toilet without water, allowing the vacuum pump to shut off after the flush. Repeat three times.
(This procedure will minimize any remaining water in the sanitation hoses.)
5. Turn off power to the vacuum pump.
6. Completely pump out holding tank.
If system will be subjected to freezing temperatures, please follow above procedure, then winterize system.
5
MAINTENANCE
Maintenance intervals and normal parts replacement vary widely depending on numerous factors such as:
type of vessel, frequency of system use, quality of flushing water, etc. The chart below is intended strictly as a
general guideline. Owner discretion and consideration of actual usage must be the first basis for determining
proper maintenance levels.
Maintenance Procedure
Approximate Maintenance Level
Follow cleaning procedures above.
Tighten all clamps, including base clamp ring.*
Check all wire connections.
Check & tighten water valve mounting screws.
Clean filter screen in water valve.
Check vacuum pump and in-line duckbill valves.
Check toilet seals.
Check vacuum breaker.
Check water valve.

VACUUM TESTER
Dometic has developed a simple tool to assist in identifying
the location of vacuum leaks. The vacuum tester consists of a
vacuum gauge and a cone-shaped plug. Inserting the plug in the
inlet of the vacuum tank or generator isolates the toilet from the
system. In this way a troublesome leak can easily be located
in either system.
Order only the Vacuum Tester (part number 318530002) or
as part of the complete system VacuFlush® maintenance kit
(part number 385310228).
Vacuum Tester
SERVICE TIP
Checking for leaks behind or under toilets or other appliances can make it difficult to locate the source. Dripping
water at room temperature makes it difficult to feel wetness. Taking four or five sheets of toilet tissue and wiping
all seams and waterline connections offers a simple means of locating the general area of the leakage. Start at
the top of the unit since gravity will cause a leak to run downward. When the tissue comes in contact with the
leaking water, it will immediately change texture.
