MARINE SANITATION REGULATIONS
IMPORTANT INFORMATION BEFORE OPERATION
1. Fill freshwater tank and add deodorant to holding tank through toilet bowl.
(See System Start-Up Section, page 5.)
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 dealer or see the Parts Distributor section of
this manual.
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 until contents
clear bowl. A sharp popping noise is
normal when the vacuum seal is broken
and flushing action begins. Be sure to
hold lever down for three (3) seconds.
If flush lever is accidentally released
before waste clears bowl, do not at-
tempt 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. Refer to the Deodorants and
Special Tissue section in this manual
for more information.
All boats with fixed toilets in U.S. waters and in the waters of some other countries are required to be equipped
with an operable marine sanitation device (MSD). The VacuFlush system is a holding tank or Type III system
as defined by the U.S. Coast Guard.
Type III systems are designed to permit operation of the toilet without the direct discharge of untreated waste
after every flush. This means onboard toilet facilities can be used when the boat is near swimmers, beaches
or shellfish beds.
Type III systems can be discharged at marina dockside pump-out stations or, if in coastal waters, a minimum
of three miles offshore. Overboard discharge capability must remain secured while within the three-mile
limit. The overboard discharge pump is activated by a keyed switch located in the toilet compartment. This
key should be removed at all times except when discharge pump is operating.
Sewage from any source should not be discharged directly into our waters. If you are interested in learning
more about this issue, please contact Dometic at the phone number or address listed on the back page of this
manual. Request Clean Water Notebook, Volumes 1 and 2.
NORMAL OPERATION

4
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 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.
VacuFlush toilets are equipped with an integral vacuum breaker which prevents the possible contamination of the
potable water supply.
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 min-
ute. In a properly operating system, the stored vacuum will slowly dissipate between flushes, permitting the vacuum
pump to quickly renew the vacuum.
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
prevent backflow of waste and vacuum.
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. Its compact size makes
it especially well-suited to smaller crafts.
Holding Tanks: Holding tanks from Dometic are made of super-strong, 3/8" (9.5mm) thick polyethylene — 50% thicker
than most other holding tanks. Each unit has a solid, one-piece construction with no seams for unmatched durability.
Tanks come in several capacities and shapes. Contact Dometic for details. A deodorant additive is required to keep
the holding tank odor-free. See Deodorants and Special Tissue section for further information.
TankWatch® Level Indicator: The TankWatch unit utilizes micro-float switches which activate an indicator panel. The
inspection cap in the holding tank contains the micro-float switch units. The adjustable probe assemblies are flexible
polybutylene tubing and are designed to flex when tank contents move.
In-Line Vent Filter: Our SaniGardTM vent filter has special odor-removing filter materials to help keep your boat smelling
clean and pleasant. Heavier-than-air malodors accumulate in the holding tank. The SaniGard vent filter has a special
type of activated filter media to remove these odors before they offend. Each cartridge is good for an entire season,
and is easily replaced for a fresh start. Replacement cartridges are available from your local marine dealer.
Dockside Discharge Deck Fitting: The holding tank is connected to a deck discharge fitting. This fitting, in turn,
can be connected to a dockside pump which may have a rubber, cone-shaped nozzle or a cam lock fitting. Refer
to Accessories section for further information on the NozAll™ fitting which makes using a dockside pump easy and
convenient.
Discharge Pump: Our T-series SaniPumpTM discharge pump can run dry without harm and draws just 6 amps at 12
VDC. The discharge pump has a flow rate of just over 5.25 gallons per minute (11.4 liters per minute). Emptying an
onboard tank usually takes four to six minutes. The T-pump is connected to a through-hull fitting. Check the section
on Marine Sanitation Regulations for information on areas where discharge is allowed.

5
SYSTEM START-UP
1. Turn on inlet water supply.
2. Turn on electrical power to system.
3. Flush water into system by depressing flush lever until water starts flowing to the vacuum pump, approxi-
mately 15 seconds. The vacuum pump will run for approximately 60 to 90 seconds until system reaches
operating vacuum level and then will shut off.
WINTERIZING
At the end of each season, the SeaLand toilet should be winterized for
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. C).
Do not remove brass 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.
The SeaLand toilet should be cleaned regularly for maximum sanitation and
operational efficiency. You can clean it just as you would a household toilet.
Do not use caustic chemicals, such as drain-opening types, as they
will damage the seals.
BOWL CLEANING: For stubborn stains, use SeaLand® Bowl and Seal
Cleaner (Fig. A). It’s manufactured especially for use with SeaLand toilets.
In certain locations where water is hard, a build-up of lime may dull the toilet
bowl finish. Restore the shine with this SeaLand cleaner. If you cannot find
it in your area, contact Dometic for your nearest dealer. If the cleaner is not
available, you can also use Bar Keepers Friend® cleanser. It is not necessary
to vigorously scrub with either product. Please follow label instructions.
SEAL CLEANING: After an extended time, mineral deposits from hard
water can build up under the edge of the rubber bowl seal, resulting in a
slow leakdown of water from the bowl. To prevent this mineral build-up,
periodically clean under the bowl seal with SeaLand Bowl and Seal Cleaner
(Fig. B).
1. Shut off water supply.
2. Apply cleaner onto the seal cleaning tool (supplied with new toilet),
open the flush ball by pressing on flush lever, and scrub under the seal.
Make sure to push bristles between bottom of seal and top of flush ball
surface to scrub all parts of seal that come into contact with flush ball.
3. Close ball and wait 2-3 minutes.
4. Open flush ball. Use brush and water to rinse away cleanser and loosened deposits.

DEODORANTS AND SPECIAL TISSUE
Your VacuFlush sanitation system requires the regular addition of a deodorant product to reduce malodors
and to help break down holding tank contents. Several factors should be considered in selecting a deodorant
product.
Liquid or Granulated: Liquid products obviously work more quickly by readily going into solution. Granulated
powder formulations, on the other hand, have the advantage of requiring less storage space and are less likely
to leak if the package is inadvertently damaged.
Formaldehyde versus Non-Formaldehyde: Dometic manufactures both types of deodorants. Generally
speaking, formaldehyde formulas control odor very effectively at all temperatures and with all degrees of water
hardness. SeaLand Environment-Friendly brand, which is formaldehyde free, is similarly effective.
Environmental Hazards: If you would like further information on the impact of holding tank deodorants, call
or write Dometic at the number and address listed on the back page of this manual. Request a copy of Clean
Water Notebook, Volume 5, which provides complete information in this regard.
How Much Deodorant and How to Add It: The deodorant is added directly into the toilet bowl, then flushed
into the holding tank. Follow bottle or package instructions. Conditions of extremely warm weather, longer waste
holding time and larger tank capacities may require more deodorant treatment. Also, to maintain optimum
efficiency in odor control, the waste holding tank should be cleaned thoroughly at least once or more each
season depending on use.
Why Not Use Household Toilet Paper in Your SeaLand Toilet. Household tissues often contain adhesives
which bond together the paper fibers from which the tissue is made. The adhesives prevent the tissue from
breaking apart, and their use in “ultra-low flow” systems can cause system clogging. SeaLand tissue is especially
designed for use in low water toilet systems. Its rapid dissolving properties minimize the amount of residual
paper in the holding tank and allow deodorizers to work more efficiently.
SeaLand versus Other Brands: Dometic constantly strives to provide our system owners with effective prod-
ucts that have minimal environmental impact and good value. Many other deodorant products do not measure
up to our standards of performance and value.

ACCESSORIES
NozAllTM Pumpout Adapter: The NozAll pumpout adapter
provides an airtight seal between your boat’s deck waste
fitting and the pumpout station nozzle. Just screw your
personal NozAll adapter into your deck fitting, and be as-
sured of an airtight connection for pumping out holding tank
contents. Each item contains a glass-filled nylon NozAll
adapter, gasket and vinyl cap. Item number 343502 (1-1/2"-
11.5 tpi), 343503 (1-1/4"-11.5tpi), or 343504 (1-1/4"-16tpi).
VacuFlush Status Panel: An ideal add-on to any
VacuFlush system. The Status Panel is mounted in the
bathroom compartment. A green light indicates sufficient
vacuum is available for the next flush. A red light indicates
the vacuum level is building and the pump is running.
Each panel has an integral circuit breaker which allows the
system to be shut down at night. Order part number 500012
(12VDC) or 500024 (24/32VDC).
Optional Vacuum Generator Shut-down Relay: This
relay can be added to automatically shut down power
to the VacuFlush toilet system to prevent overfilling of
the onboard holding tank. Order part number 310289
(12 VDC) or 310290 (24 VDC).
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
530002) or as part of the complete system mainte-
nance kit (Part Number 310228).
SERVICE TIP
Checking for water 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 tis-
sue 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.
