and life.
WARNING!
HAZARD OF FLOODING – If toilet rim is
below the waterline at ANY time (during any conditions of heel, load or trim) and is connected to
ANY through-the-hull fittings, properly positioned
ventilated (vented) loops MUST be installed in
intake* or discharge piping to prevent potential
back siphonage of seawater into the boat. Failure
to do so can result in flooding which can cause
loss of property and life.
Warnings
The following cautionary statements
must be read and understood before
installing, servicing and/or operating this product. Modification of this
product may result in property damage.
* if connected to raw water
WARNING!
HAZARD OF FLOODING – If the toilet
uses fresh water for flushing and is connected
directly or indirectly to a shoreside municipal
water system at ANY time, shoreside water connections MUST be disconnected if the boat is
unattended (even if boat is unattended for a brief
period). Failure to do so can result in flooding
which can cause loss of property and life.
Dometic Sanitation Corporation recommends that
a qualified marine technician or electrician install
or service this product. Equipment damage, injury
to personnel or death could result from improper
installation. DOMETIC SANITATION CORPORATION ACCEPTS NO RESPONSIBILITY OR
LIABILITY FOR DAMAGE TO EQUIPMENT,
OR INJURY OR DEATH TO PERSONNEL THAT
MAY RESULT FROM IMPROPER INSTALLATION, SERVICE OR OPERATION OF THIS
PRODUCT.
WARNING!
HAZARD OF FLOODING – If toilet uses
raw water for flushing at ANY time, a raw water
pump controlled by an automatically operating
demand switch MUST NOT be installed. If the
onboard water valve or any plumbing connections
were to leak, the automatically operated pump
would start and could flood the boat. Failure to
comply can cause loss of property and life.
WARNING!
HAZARD OF FLOODING – If the toilet
is connected to ANY through-the-hull fittings,
properly installed seacocks MUST be installed
in all piping connected to through-the-hull fittings. Seacocks MUST be easily accessible to
all users of the toilet or secondary valves fitted
in hoses where they are easily accessible. All
valves MUST be full bore valves and of marine
quality. Screw-to-close gate valves are not recommended. Failure to do so can result in flooding which can cause loss of property and life.
WARNING!
HAZARD OF FLOODING – Before
beginning any work on this product, be sure that
all electrical power to the unit has been turned
off and that seacocks are in the CLOSED or OFF
position. Failure to do so can result in flooding
which can cause loss of property and life.
WARNING!
HAZARD OF SHOCK OR FIRE –
Always use recommended fuse, circuit breaker
and wire size. Failure to do so can result in fire
that can cause the loss of property and life.
WARNING!
HAZARD OF FLOODING – If toilet
is connected to ANY through-the-hull fittings,
ALWAYS close seacocks when toilet is not in use
(even if boat is unattended for a brief period). All
passengers MUST be instructed on how to close
valves when the toilet is not in use. Failure to do
so can result in flooding which can cause loss of
property and life.
CAUTION: Overfilling the holding tank
can create serious damage to the sanitation system, such as rupturing the holding tank
and releasing tank contents into the bilge. To
prevent this possibility, Dometic strongly recommends using the “full” tank shut-down relay in
the toilet’s electronic control module. The “full”
signal from the holding tank can be generated
by an optional Tank “Full” Float Assembly, or a
TankWatch Level Monitor Kit (see page 19). A
“Power/Tank Full” lighted panel is also available
(see page 18).
WARNING!
HAZARD OF FLOODING – If toilet is
connected to ANY through-the-hull fittings, ALL
flexible hoses must be of marine sanitation quality and must be secured to ANY fittings (such as
those at seacock, vented loop or toilet) with two
stainless steel, worm-drive hose band clamps at
each connection. Connections MUST be checked
Toilet Start-up
3. Toss several sheets of toilet paper into
bowl and repeat the cycle. The bowl should
completely clear.
1. Turn on water supply line to toilet.
2. NORMAL Flush – Press NORMAL button once. After about 9 seconds of water
flow, macerator pump will start and run for
about 6 seconds to clear bowl. It then takes
4 seconds to refill the bowl.
4. LOW Flush – Press LOW button. After 3
seconds of water flow, the macerator will
complete the discharge within 6 seconds. It
then takes 4 seconds to refill the bowl.
Toilet Operation
SeaLand macerator toilets are flushed by pressing one of three flush mode buttons:
CAUTION!
DO NOT FLUSH FOREIGN
OBJECTS – SeaLand toilets are designed to
flush only water, bodily wastes and rapiddissolving toilet tissue. Do not flush wet
wipes, sanitary napkins, condoms, diapers,
razor blades, paper cups, cotton swabs,
food, hair or liquids such as oils or solvents
as clogging or damage to the toilet or sanitation system may occur.
NORMAL – Flushes solids. Uses only
.82 gal. (3.1 L) per flush. Flush cycle lasts
19 seconds.
LOW – For liquid-only flushes. Uses only
.42 gal. (1.6 L) per flush. Flush cycle lasts
13 seconds.
EMPTY – Empties water from bowl to avoid
splashing during travel.
Electronic touchpad
The Dometic touchpad activates a powerful
turbine macerator pump in each toilet. The
high-speed turbine siphons water and waste
from the toilet bowl, through the macerator
pump, and into the discharge line/holding tank.
CAUTION!
TURN OFF ELECTRICITY AND
WATER TO TOILET IF IDLE FOR LONG
PERIODS OF TIME – If people will not be
using the boat for a long time (vacations,
maintenance, off-season, etc.), or in the
event of a long interruption in electricity,
electrical power and water supply to the
toilet should be shut off. See additional
instructions on page 15 regarding “Extended
Periods of Non-Use – Laying Up Toilet.”
INSTALLATION – System Diagrams
Flush Water Options
an electrically operated water valve that opens
during Normal and Low flushing modes.
SeaLand toilets are equipped with an in-line
check valve or air gap to prevent contamination
of onboard potable supplies. See later sections
for specific information on connecting the water
line to the toilet.
FRESH WATER SYSTEM – All SeaLand macerator toilets can operate with an onboard pressurized freshwater system with a minimum flow rate
of 2.5 gpm (9.5 lpm) at the toilet. Onboard freshwater demand systems include a water pump that
automatically draws water from a water storage
tank when a valve anywhere in the piping system
is opened. SeaLand toilets are equipped with
INSTALLATION NOTES
• Use cold water only.
• Water supply line: 1/2” (13mm) ID; toilet inlet
fitting is 1/2” (13mm), 14 TPI.
• Requires 2.8 GPM (10.6 LPM) demand water
pump or greater, depending on line restrictions.
• Include shut-off valve in water line for
maintenance purposes.
RAW WATER SYSTEM – SeaLand macerator toilets can flush on seawater but require a
separate pump for this purpose. The pump is
activated by the signal from the toilet’s electronic
control module that would operate the integral
water valve in a fresh water system. Since raw
water pumps operate at a higher amperage than
the freshwater water valve, a 12 or 24 volt DC
electrical relay must be inserted into the electrical
cables connected to the pump. A kit is available
to convert the standard freshwater toilet to raw
water. The kit contains the electrical relay, hose
insert adapter and related hardware.
Please contact your nearest Dometic Sanitation
sales office or distributor for complete details.
WARNING!
HAZARD OF FLOODING – If toilet
uses raw water for flushing at ANY time, a
raw water pump controlled by an automatically operating demand switch MUST NOT
be installed. If the onboard water valve or
any plumbing connections were to leak, the
automatically operated pump would start and
could flood the boat. Failure to comply with
this warning can cause loss of property and
life. See other WARNINGS (p. 4).
INSTALLATION NOTES
• See Notes from Fresh Water System.
• Seacock must be full-flow, marine-quality valve (not
screw-to-close type).
• Use primary and secondary raw water filters.
• Raw water pump must not be demand type. Pump
is controlled by signal from Control Module near toilet.
• Position vented loop as shown between discharge
side of water pump and toilet. Must be equipped
with integral check valve that permits air into line to
prevent siphoning.
INSTALLATION – SYstem Diagrams (cont’d)
Discharge piping
SeaLand macerator toilets can be connected to
1-1/2-inch (38mm) ID flexible sanitation hose or
adapted to 1-inch (25mm) ID hose with a 1-1/2”
x 1” adapter available from a SeaLand product
dealer. Connections can be made either through
the floor or out the rear of the toilet above the
floor.
permeates through the wall of the hose. Avoid
this condition by installing the tank in the lowest
position in the boat so that hose contents will drain
into the holding tank. Rigid PVC pipe can also be
installed in runs that hold trapped sewage. The
marine sanitation hose most resistant to odor
permeation is OdorSafe Plus® hose, available
from your local SeaLand product dealer.
Flexible hoses that contain sewage from any
marine toilet will create unpleasant odor that
note: Vertical loops in discharge line of toilet are additive.
Total upward vertical distance must not exceed 9.8 ft. (3 m).
Vented loops
Ventilated or vented loops are intended to
prevent back siphonage of seawater into the
toilet. If the toilet rim is below the waterline at
ANY time in ANY conditions of heel, load or
trim, a vented loop MUST be installed in the
hose run at a point at least 8-inch (20.3 cm) above
the waterline in all such conditions. See vented
loop fitting manufacturer’s recommendation for
further information.
WARNING!
HAZARD OF FLOODING – If toilet rim is below the
waterline at ANY time (during any
conditions of heel, load or trim)
and is connected to ANY throughthe-hull fittings, properly positioned ventilated (vented) loops
MUST be installed in intake*
or discharge piping to prevent
potential back siphonage of
seawater into the boat. Failure
to do so can result in flooding
which can cause loss of property
and life.

INSTALLATION – System Diagrams (cont’d)
Holding Tanks
Seacocks
SeaLand macerator toilets operate with most
holding tank or treatment systems. If installed
with a holding tank, however, the capacity of
the tank should be sufficient to avoid the inconvenience of discharging it too frequently. The
average flush volume is .96 gallons (3.6 liters)
including flushwater and waste. A 30-gallon tank
(114-liter) will become full in about 30 flushes.
Seacocks are required by various marine regulations. Only full flow, marine quality valves are
recommended. Some regulations require the
seacocks be configured so they can be locked in
a closed position. Seacocks MUST be installed
according to the manufacturer’s instructions.
WARNING!
HAZARD OF FLOODING – If the toilet
is connected to ANY through-the-hull fittings,
properly installed seacocks MUST be installed
in all piping connected to through-the-hull
fittings. Seacocks MUST be easily accessible
to all users of the toilet or secondary valves
fitted in hoses where they are easily accessible. All valves MUST be full bore valves and
of marine quality. Screw-to-close gate valves
are not recommended. Failure to do so can
result in flooding which can cause loss of
property and life.
CAUTION: Overfilling the holding
tank can create serious damage to
the sanitation system, such as rupturing the
holding tank and releasing tank contents into
the bilge. To prevent this possibility, Dometic
strongly recommends using the “full” tank
shut-down relay in the toilet’s electronic control module. The “Full” signal from the holding tank can be generated by any SeaLand
TankWatch level monitor system.
Refer to the dimensional drawings on page 3
and the chart below to determine the optimum
toilet for a given installation.
Riser Step or Plinth
installations (seat height)
SeaLand macerator toilets are available in
three models to accommodate various spaces.
While the major factor in selecting a model for
a boat is the space provided to fit the toilet
into the head compartment, seating height is
also important. A comfortable seating height is
about 20 inches (508 mm).

Routine Toilet Maintenance
MONTHLY:
1. Inspect toilet, plumbing and plumbing connections, wires and wiring connections.
2. Open and close all valves, including seacocks.
3. Check in-line water filters and vented loops for blockage.
YEARLY:
1. Check internal filter in water valve. Also check filter when water flow into toilet bowl becomes
insufficient.
14
Extended periods of non-use
– Laying up toilet
The macerator pump and sanitation hoses should be treated if toilet will not be needed for an
extended period of time (more than two weeks and especially in hotter weather).
1. Flush toilet in “Normal” mode and add 4 oz. (118 ml) of liquid biodegradable laundry detergent
(should NOT contain bleach or environmentally harmful substances). Note: If using sea water
for flushing, shut off power to sea water pump and add fresh water by pouring directly into the
bowl during the flush cycle.
2. Flush toilet at least five times.
3. Turn off water supply to toilet.
4. Flush the toilet without water. Repeat three times. (This procedure will minimize any remaining
water in the macerator pump.)
5. Turn off power to the toilet (and water supply pump if flushing with sea water).
6. Close all seacocks.
If system will be subjected to freezing temperatures, please follow above procedure, and then
winterize system as described below.
Winterizing
At the end of each season, the SeaLand macerator toilet should be winterized for storage by using
potable water-safe antifreeze (if boat or vehicle will be exposed to freezing temperatures).
NOTE: Use nontoxic antifreeze designated for potable water systems. (See boat or vehicle
owner’s manual.)
CAUTION: Never use automotive-type antifreeze in freshwater systems.
PRESSURIZED FRESH WATER SYSTEM
1. Drain potable water tank and empty holding tank.
2. Add freshwater antifreeze to potable water tank.
3. Flush potable water antifreeze and water mixture through toilet(s) and into entire system,
including the waste holding tank, diverter valve connections, discharge pumps, etc. Turn off
power to toilet.
Each installation is different, so amounts may vary. User discretion is required to assure
adequate protection.
RAW WATER SYSTEM
Parts required:
• 1-1/2-inch (38mm) ID hose, about 3-feet (1m) long
• 5/8-inch (16mm) ID hose, about 3-feet (1m) long
• two containers
1. Close intake and discharge seacocks. See Hazard of Flooding risks on page 4.
2. Turn off power to toilet.
3. Disconnect and drain intake hose, discharge hose, and in-line filters.
4. Connect 5/8-inch (16mm) ID hose to raw water pump intake and 1-1/2-inch (38mm) ID hose to
toilet discharge.
5. Place one container under hose connected to toilet’s discharge.
6. Place hose connected to intake pump into bucket with antifreeze and pour antifreeze in other
container.
7. Turn on power to toilet and flush until antifreeze is removed from toilet.
8. Disconnect power to toilet and reconnect all intake and drain hoses.

Deodorants and Special Tissue
Your SeaLand MasterFlush toilet 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 work more quickly by readily going into solution.
Granulated powder formulations 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. Both SeaLand® NATURAL Environment-Friendly and Clean ‘n
Green™ brands, which are formaldehyde-free, are similarly effective.
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 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.
