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

2.1 Warnings – marine and recreation vehicle applications

The following statements must be read and understood before installing, servicing and/or

operating this product on a boat. Modiﬁcation of this product may result in property damage.

Dometic recommends that a qualied marine or RV technician or electrician install or service this

product. Equipment damage, injury to personnel or death could result from improper installation.

DOMETIC ACCEPTS NO RESPONSIBILITY OR LIABILITY FOR DAMAGE TO EQUIPMENT, OR PERSONAL

INJURY OR DEATH THAT MAY RESULT FROM IMPROPER INSTALLATION, SERVICE OR OPERATION

OF THIS PRODUCT.

Dometic 8700 Series MasterFlush ToiletGeneral safety instructions

Caution! Hazard of Flooding

If toilet uses raw water for ushing at ANY time, a raw water pump controlled by an auto-

matically 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 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! Hazard of Shock or Fire

Always use recommended fuse, circuit breaker and wire size. Failure to do so can result in

re that can cause the 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.

Caution! 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 ttings, 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 ooding which can cause loss of

property and life.

* if connected to raw water

Caution! Hazard of Flooding

If toilet is connected to ANY through-the-hull ttings, ALL exible hoses must be of marine

sanitation quality and must be secured to ANY ttings (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. Failure to comply can result in

ooding which can cause loss of property and life.

Caution! Hazard of Flooding

If the toilet is connected to ANY through-the-hull ttings, properly installed seacocks MUST

be installed in all piping connected to through-the-hull ttings. Seacocks MUST be easily

accessible to all users of the toilet or secondary valves tted 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 ooding which can cause loss

of property and life.

Notes

Use cold water only. Include shut-off valve in water line for maintenance purposes.

Use primary and secondary raw water lters.

Raw water pump MUST NOT be demand-type. Pump is controlled by control module.

Install vented loop as shown. It must be equipped with integral check valve that permits air into line to

prevent siphoning.

Dometic 8700 series 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 fresh-water

demand systems include a water pump that

automatically draws water from a water

Dometic 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. If the raw water pump draws more than 18 amps of

current, a 12 or 24 V DC electrical relay must be installed.

piping system is opened. Dometic toilets are

equipped with an electrically operated water

valve and a backow preventer to prevent

contamination of onboard potable supplies.
