Warnings

The following cautionary statements must be read and understood before i n s t a l l i n g , s e r v i c i n g a n d / o r o p e r - ating this product. Modification of this product may result in property damage.

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 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 – 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.

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 MUSTbe checked

frequently for integrity. Failure to comply can result in flooding which can cause loss of property and life.

WARNING!

HAZARD OF FLOODING – If toilet rim is below the waterline atANY 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.

* 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.

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 – 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.

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 the addition of a “full” tank safety shutdown relay to the toilet’s electronic control module (a pre-wired base is provided for this relay inside the module). The “full” signal from the holding tank can be generated by the optional Tank “Full” FloatAssembly, or a TankWatch Level Monitor Kit (see page 19) A “Power/Tank Full” lighted panel is also available (see page 19).

Toilet Start-up

1.Open maintenance water valve completely to assure good bowl rinse.

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.

3.Toss several sheets of toilet paper into bowl and repeat the cycle. The bowl should completely clear.

4.LOW Flush – Press LOW button twice. After about 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:

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 SeaLand 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!

D O N O T F L U S H F O R E I G N 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.

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 14 regarding “Extended Periods of Non-Use – Laying Up Toilet.”

INSTALLATION – System Diagrams

Flush Water Options

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

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.

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.

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.

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. 3).

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.

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
