to obey the following warnings could result in death or serious injury.

• 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.

• If the 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 frequently for integrity.

• If the toilet rim is ever less than 8 in. (20 cm) above the highest possible 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 (if connected to raw water) or discharge piping to prevent potential back siphonage of seawater into the boat. Vented loops must be equipped with integral check valve that permits air into line to prevent siphoning.

• 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.

• Do not connect raw water flush toilet (models 7160, 7260) to an onboard pressurized water system.

• Before beginning any work on this product, be sure that all electrical power to the unit has been turned off and that the seacocks are in the closed or off position.

WARNING: Electrical shock and/or

fire hazard. Follow all local regulations for electrical installations. NOTICE: Overfilling the holding tank can cause serious damage to the sanitation system, such as rupturing the holding tank and releasing tank contents into the bilge. To prevent this possibility, Dometic recommends using a full tank shut-down relay. The full signal from the holding tank can be generated by an optional Dometic DTM01C tank monitor or DTM04 four- level tank monitor system. Follow all local regulations for waste tank discharge. 3 Intended use The Macerator toilet (hereinaer referred to as toilet or product) provides an electric-flush toilet that macerates waste and pumps it either to a holding tank or other effluent storage/ disposal system, or overboard. Operated by a remote flush switch, the toilet allows the user to add water to the bowl (before or aer flushing) and to flush the toilet by pushing a button. This toilet is designed for use in marine applications and is only suitable for the intended purpose and application in accordance with these instructions. This manual provides information that is necessary for proper installation of the toilet. Poor installation and/or improper operating or maintenance will result in unsatisfactory performance and a possible failure.

Do not connect sea water flush toilet inlet line to a pressurized freshwater system. This will result in a continuously running freshwater pump, which can possibly overflow the toilet bowl, and flood the boat. Failure to obey this warning could result in death or serious injury.Installation Macerator Toilet

WARNING: Contaminated water

hazard. Do not connect sea water flush toilet inlet line to an onboard potable water system in any way. This can cause contamination of the potable water system. If fresh water is desired, purchase the freshwater-flush version of the toilet, or provide a separate freshwater tank that supplies water only to the toilet. Failure to obey this warning could result in death or serious injury. Be sure to install a vented loop that will not prevent the required water flow to the toilet when it is flushed. An electric solenoid type is recommended.
