Note
Supplementary information for operating the device.
fig. 1 A, page 2 : This refers to an element in an illustration. In this example, item A in
gure 1 on page 2.
Caution!
Safety Instruction: Failure to observe this instruction can cause material damage and
impair the function of the device.
2 General safety instructions
The manufacturer will not be held liable for claims for damage resulting from the following:
• Faulty assembly or connection
• Damage to the unit from mechanical inuences, misuse or abuse
• Alterations to the unit without express written permission from the manufacturer
• Use for purposes other than those described in the operating manual
SeaLand MasterFlush Toilet Notes on using the manual
Caution! Hazard of Flooding
If toilet is connected to ANY through-the-hull ttings, 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
ooding which can cause loss of property and life.
Caution! Hazard of Flooding
If the toilet uses fresh water for ushing and is connected directly or indirectly to a shore-
side municipal water system at ANY time, shoreside water connections MUST be discon-
nected if the boat is unattended (even if boat is unattended for a brief period). Failure to do
so can result in ooding which can cause loss of property and life.
Caution! 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 ooding which can cause loss of property and life.

Caution!
Overlling 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 pos-
sibility, Dometic 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
Dometic DTM01C tank monitor or DTM04 four-level tank monitor system.
3 Intended use
The SeaLand MasterFlush toilet provides an electric-ush toilet that macerates waste and pumps
it to a holding tank or other efuent storage/disposal system. Operated by a wall-mounted ush
switch, the toilet allows the user to add water to the bowl (before using or ushing) and to ush the
toilet by pushing a button. The Dometic ush switch panel includes lights to indicate when electric
power to the toilet is activated, and when the holding tank (if applicable) is full.
3.1 Benefits
Convenient electronic flush. Add water or ush with the touch of a button.
Choice of two water consumption settings. “Normal” ush uses 0.85 gal. (3.2 liters) per ush and adds
water to bowl after ush; “Dry Bowl” setting uses only 0.45 gal. (1.7 liters) per ush and does not add
water to the bowl.
Versatile installation. Powerful macerator pump allows toilet to be located up to 98 ft. (30 m) away and
9.8 ft. (3 m) below holding tank or other discharge line destination.
“Power on” and “full tank” indicator lights. Dometic or other ush switch panel indicates when
electrical power to toilet is activated, and when holding tank is full (when connected to holding tank level
indication system).
Automatic “full tank” shut-down. When connected to a holding tank level indication system, the
MasterFlush toilet control module will shut off electrical power to the toilet when the holding tank is full.
This safety features prevents overlling the holding tank, which may cause damage to the boat.

Specifications SeaLand MasterFlush Toilet
6.1 Toilet system start-up
1. Turn on water supply to toilet.
2. Press “Flush” switch (g. 3 2) once. After nine seconds of water ow, macerator pump will start
and run for about six seconds to clear bowl. It will take about ve seconds to rell bowl.
3. Toss several sheets of toilet paper into bowl and repeat
cycle. The bowl should completely clear.
6.2 Normal toilet operation
ADDING WATER TO TOILET BOWL
Press “Add Water” switch (g. 3 1) until desired water level
is achieved. (Water ow will shut off automatically if switch
is pressed too long to avoid overow.) More water is usually
added only when ushing solids.
FLUSHING TOILET
Press “Flush” switch (g. 3 2) down, then release it. This activates a powerful macerator pump that
siphons water and waste from the bowl, macerates, and propels the efuent through the discharge
line to the holding tank.
6 Operation
Caution – Do Not Flush Foreign Objects!
Flush only water, bodily wastes and rapid-dissolving toilet
tissue. Do not ush wet wipes, sanitary napkins, condoms,
diapers, paper cups, cotton swabs, food, hair or liquids
such as oils or solvents as clogging or damage to the toilet
or toilet system may occur.
Note
Make sure all guests understand toilet operation before use.
Note
If toilet system is equipped with Vimar or Gewiss
ush switches and indicator lights supplied by
Dometic, ush control and indicator light graphics
are the same as those on the Dometic ush panel.

SeaLand MasterFlush Toilet Operation
6.4 Indicator lights
“POWER ON” INDICATOR
On the Dometic ush switch panel, a steady green “Power On” light (g. 3 3, p. 6) indicates when
electrical power to the toilet is activated. A momentary ashing green light indicates when ush
mode is changing.
“FULL TANK” INDICATOR
The Dometic ush switch panel includes a red “Full Tank” light (g. 3 4, p. 6) to indicate when the
holding tank is full and should be pumped out. When the red light is illuminated, electrical power to the
toilet automatically shuts off to prevent possible overlling of the holding tank.
6.3 Changing flush modes
MasterFlush toilets offer two ush settings to help manage water consumption:
Normal flush – Uses 0.85 gal. (3.2 liters) per ush. Adds water to bowl after every ush.
Dry Bowl flush – Uses 0.45 gal. (1.7 liters) per ush. Does not add water to bowl after ush.
To change from Normal to Dry Bowl ush setting, press “Flush” switch for about ve seconds. When
“Power On” light (g. 3 3, p. 6) begins ashing, release “Flush” switch. Flush mode has been
changed to Dry Bowl setting. Change mode to Normal ush by following the same procedure.
6.5 Bidet operation
(toilet models with
integrated bidet only)
1. Turn on bidet faucet by
turning handle away from
toilet (g. 4 ).
2. Adjust water temperature by
turning handle up for warm
water and down for cool
water (g. 5 ).
3. Use electronic “Flush” switch
to clear toilet bowl during
and after bidet use.
Caution! Hazard of Flooding
Be sure to shut bidet faucet off completely after use.

7.1 Cleaning the toilet
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.
7.2 Routine maintenance
MONTHLY
1. Inspect toilet, plumbing, and plumbing connections, wires, and wire connections.
2. Open and close all plumbing valves, including seacocks (for boat applications).
3. Check in-line water lters and vented loops for blockage.
YEARLY
Check water valve lter. Also check water valve lter if water ow into toilet becomes insufcient.
7.3 During extended periods of non-use
The macerator toilet and sanitation hoses should be protected if toilet will not be needed for an
extended period of time (more than two weeks, especially in hot 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
ushing, shut off power to sea water pump and add fresh water by pouring directly into the bowl
during the ush cycle.
2. Flush toilet with water at least ve 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.
If system will be subjected to freezing temperatures, please follow above procedure, and then
winterize system as described in next section.
7 Maintenance and winterizing
Caution
To avoid damaging internal seals, do not clean toilet with abrasive cleaners, caustic
chemicals, or lubricants and cleaners that contain alcohols or petroleum distillates.

7.4 Winterizing
At the end of each season, the SeaLand MasterFlush macerator toilet should be winterized for
storage by using potable water-safe antifreeze (if boat or vehicle will be exposed to freezing
temperatures).
Caution
Never use automotive-type antifreeze (ethylene glycol) in freshwater systems.
