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, macer- ates, 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 .

Cleaning the toilet

To maintain the toilet’s original, lustrous appearance, use Dometic Toilet Bowl Cleaner or other non-abrasive bathroom and toilet bowl cleaners . Please follow label directions .

Caution

To avoid damaging internal seals, do not clean toilet with abrasive cleaners, caustic chemicals, or lubricants and cleaners that contain alcohols or petroleum distillates .

Routine maintenance

MONTHLY

1 . Inspect toilet, plumbing, and plumbing connections, wires, and wire connections . 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 .

RAW WATER SYSTEM

Parts required:   

• 1 .5 in . (38 mm) ID hose, about 3 ft . (1 m) long
