INSTALLATION – SYSTEM DIAGRAMS
FLUSH WATER OPTIONS
FRESH WATER SYSTEM – All SeaLand macerator toilets can operate with an onboard pressurized freshwater system with a minimum ow 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
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 specic information on connecting the water
line to the toilet.
INSTALLATION NOTES
• Use cold water only.
• Water supply line: 1/2” (13mm) ID; toilet inlet
• Requires 2.8 GPM (10.6 LPM) demand water
• Include shut-off valve in water line for

maintenance purposes.
RAW WATER SYSTEM – SeaLand macerator toilets can ush 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.
INSTALLATION NOTES
• See Notes from Fresh Water System.
• Seacock must be full-ow, marine-quality valve (not
screw-to-close type).
• Use primary and secondary raw water lters.

WARNING!
HAZARD OF FLOODING – If toilet
uses raw water for ushing 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 ood the boat. Failure to comply with
this warning can cause loss of property and
life. See other WARNINGS (p. 3).

INSTALLATION – SYSTEM DIAGRAMS (cont’d)
DISCHARGE PIPING
SeaLand macerator toilets can be connected to
1-1/2-inch (38mm) ID exible 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 oor or out the rear of the toilet above the
oor.
Flexible hoses that contain sewage from any
marine toilet will create unpleasant odor that
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.
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
WARNING!
HAZAR D OF FLO OD
ING – 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 ttings, properly positioned ventilated (vented) loops
MUST be in stall ed in intake*

INSTALLATION – SYSTEM DIAGRAMS (cont’d)
HOLDING TANKS
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 sufcient to avoid the inconvenience of discharging it too frequently. The
average ush volume is .96 gallons (3.6 liters)
including ushwater and waste. A 30-gallon tank
(114-liter) will become full in about 30 ushes.
CAUTION: Overlling 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 the addition of a “Full”
tank safety shut-down relay to the toilet’s
electronic control module (a pre-wired base
is provided for this relay inside the box). The
“Full” signal from the holding tank can be
generated by any SeaLand TankWatch level
monitor system.
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 t the toilet
into the head compartment, seating height is
also important. A comfortable seating height is
about 20 inches (508 mm).
SEACOCKS
Seacocks are required by various marine regulations. Only full ow, marine quality valves are
recommended. Some regulations require the
seacocks be congured so they can be locked in
a closed position. Seacocks MUST be installed
according to the manufacturer’s instructions.
WARNING!
is connected to ANY through-the-hull ttings,
properly installed seacocks MUST be installed
in all piping connected to through-the-hull

DEODORANTS AND SPECIAL TISSUE
Your SeaLand 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.
Generally speaking, formaldehyde formulas control odor very effectively at all temperatures and
with all degrees of water hardness. Both SeaLand® Environment-Friendly and Clean ‘n Green™
brands, which are formaldehyde free, are similarly effective.
How Much Deodorant and How to Add It.
then ushed 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 efciency 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 bers from which the tissue is made. The adhesives prevent the
tissue from breaking apart, and their use in “ultra-low ow” 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 efciently.
SeaLand Brand versus Other Brands. We constantly strive to provide our system owners with
effective products that have minimal environmental impact and good value. Many deodorant
products do not measure up to our standards of performance and value.
Dometic manufactures both types of deodorants.
The deodorant is added directly into the toilet bowl,
