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.

• Caution! 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.

• Caution! Hazard of Flooding
  If the toilet uses fresh water for flushing 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 flooding 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 flooding which can cause 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 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.

Intended use

The Dometic 8700 series MasterFlush toilet provides an electric-flush toilet that macerates waste and pumps it to a holding tank or other effluent storage/disposal system. Operated by a wall- mounted flush switch or electronic flush handle, the toilet allows the user to add water to the bowl
(before using or flushing) and to flush the toilet by pushing a button. The Dometic flush switch panel includes lights to indicate when electric power to the toilet is activated, and when the holding tank (if applicable) is full.

Benefits

• Convenient electronic flush. Add water or flush with the touch of a button or electronic flush handle.
• Choice of two water consumption settings. “Normal” flush uses 0.85 gal. (3.2 liters) per flush and adds water to bowl after flush; “Dry Bowl” setting uses only 0.45 gal. (1.7 liters) per flush 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 flush 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 8700 series toilet control module will shut off electrical power to the toilet when the holding tank is full. This safety features prevents overfilling the holding tank, which may cause damage to the boat.

Operation

Toilet system start-up

1. Turn on water supply to toilet.
2. Press “Flush” switch (fig. 4 2) once. After nine seconds of water flow, macerator pump will start and run for about six seconds to clear bowl. It will take about five seconds to refill bowl.
3. Toss several sheets of toilet paper into bowl and repeat cycle. The bowl should completely clear.

Normal toilet operation – Dometic touchpad or other wall switch

• ADDING WATER TO TOILET BOWL
  Press “Add Water” switch (fig. 4 1) until desired water level is achieved. (Water flow will shut off automatically if switch is pressed too long to avoid overflow.) More water is usually added only when flushing solids.

• FLUSHING TOILET
  Press “Flush” switch (fig. 4 2), then release it. This activates a powerful macerator pump that siphons water and waste from the bowl, macerates, and propels the effluent through the discharge line to the holding tank.
  Caution – Do Not Flush Foreign Objects!
  Flush only water, bodily wastes and rapid-dissolving toilet tissue. Do not flush 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.

Changing flush modes
Dometic 8700 series MasterFlush toilets offer two flush settings to help manage water consumption: Normal flush – Uses 0.85 gal. (3.2 liters) per flush. Adds water to bowl after every flush. Dry Bowl flush – Uses 0.45 gal. (1.7 liters) per flush. Does not add water to bowl after flush. To change from Normal to Dry Bowl flush setting, press “Flush” switch for about five seconds. When “Power On” light (fig. 4 3) begins flashing, release “Flush” switch. Flush mode has been changed to Dry Bowl setting. Change mode to Normal flush by following the same procedure.

Indicator lights

• “POWER ON” INDICATOR
  On the Dometic flush switch panel, a steady green “Power On” light (fig. 4 3) indicates when electrical power to the toilet is activated. A momentary flashing green light indicates when flush mode is changing.

• “FULL TANK” INDICATOR
  The Dometic flush switch panel includes a red “Full Tank” light (fig. 4 4) to indicate when the holding tank is full (if connected to a tank monitoring system) and should be pumped out. When the red light is illuminated, electrical power to the toilet automatically shuts off to prevent overfill of the holding tank.

2. Open and close all plumbing valves, including seacocks.
3. Check in-line water filters and vented loops for blockage

• YEARLY
  Check water valve filter. Also check water valve filter if water flow into toilet becomes insufficient.

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 flushing, shut off power to sea water pump and add fresh water by pouring directly into the bowl during the flush cycle.
2. Flush toilet at least five 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 below.

Winterizing
At the end of each season, the Dometic macerator toilet should be winterized for storage by using potable water-safe antifreeze (if boat or vehicle will be exposed to freezing temperatures).
Note
Use nontoxic antifreeze designated for potable water systems. (See boat or vehicle owner’s manual.)
Caution
Never use automotive-type antifreeze in freshwater systems.

PRESSURIZED FRESH WATER SYSTEM

1. Drain potable water tank and empty holding tank.
2. Add freshwater antifreeze to potable water tank.
3. Flush potable water antifreeze and water mixture through toilet(s) and into entire system, including the waste holding tank, diverter valve connections, discharge pumps, etc. Turn off power to toilet.
   Each installation is different, so amounts may vary. User discretion is required to assure adequate protection.
