Dometic 8700 Series MasterFlush Toilet Notes on using the manual

2.1 Warning – recreation vehicle applications

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

operating this product on a recreation vehicle. Modiﬁcation of this product may result in property

damage.

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

regard to all applicable codes and regulations. Equipment damage, personal injury 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.

2.2 Warnings – marine 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 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.

Caution! Hazard of Flooding

If the toilet uses fresh water for ushing 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 ooding 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 ooding which can cause 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.

3 Intended use

The Dometic 8700 series MasterFlush toilet provides an electric-ush toilet that macerates waste

and pumps it to a holding tank or other efuent storage/disposal system. Operated by a wall-

mounted ush switch or electronic ush handle, the toilet allows the user to add water to the bowl

(before using or ushing) and to ush the toilet by pushing a button. The Dometic ush switch panel

includes lights to indicate when electric power to the toilet is activated, and when the holding tank (if

applicable) is full.

3.1 Beneﬁts

Convenient electronic ﬂush. Add water or ush with the touch of a button or electronic ush handle.

Choice of two water consumption settings. “Normal” ush uses 0.85 gal. (3.2 liters) per ush and adds

water to bowl after ush; “Dry Bowl” setting uses only 0.45 gal. (1.7 liters) per ush 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 ush 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 overlling the holding tank, which may cause damage to the boat.

General safety instructions Dometic 8700 Series MasterFlush Toilet

Caution! Hazard of Flooding

If toilet is connected to ANY through-the-hull ttings, 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

ooding which can cause loss of property and life.

Dometic 8700 Series MasterFlush Toilet Operation

6.1 Toilet system start-up

1. Turn on water supply to toilet.

2. Press “Flush” switch (g. 42) once. After nine seconds of water ow, macerator pump will start

and run for about six seconds to clear bowl. It will take about ve seconds to rell bowl.

3. Toss several sheets of toilet paper into bowl and repeat

cycle. The bowl should completely clear.

6.2.1 Normal toilet operation -

Dometic touchpad or other wall switch

ADDING WATER TO TOILET BOWL

Press “Add Water” switch (g. 41) until desired water level

is achieved. (Water ow will shut off automatically if switch

is pressed too long to avoid overow.) More water is usually

added only when ushing solids.

FLUSHING TOILET

Press “Flush” switch (g. 42), then release it. This activates a powerful

macerator pump that siphons water and waste from the bowl, macer-

ates, and propels the efuent through the discharge line to the holding

tank.

6 Operation

Caution – Do Not Flush Foreign Objects!

Flush only water, bodily wastes and rapid-dissolving toilet

tissue. Do not ush 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.

6.2.3 Indicator lights

“POWER ON” INDICATOR

On the Dometic ush switch panel, a steady green “Power On” light (g. 43) indicates when

electrical power to the toilet is activated. A momentary ashing green light indicates when ush

mode is changing.

“FULL TANK” INDICATOR

The Dometic ush switch panel includes a red “Full Tank” light (g. 44) 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 overll of the holding tank.

6.2.2 Changing ﬂush modes

Dometic 8700 series MasterFlush toilets offer two ush settings to help manage water consumption:

Normal ﬂush – Uses 0.85 gal. (3.2 liters) per ush. Adds water to bowl after every ush.

Dry Bowl ﬂush – Uses 0.45 gal. (1.7 liters) per ush. Does not add water to bowl after ush.

To change from Normal to Dry Bowl ush setting, press “Flush” switch for about ve seconds. When

“Power On” light (g. 43) begins ashing, release “Flush” switch. Flush mode has been changed to

7.1 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.

7.2 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 lters and vented loops for blockage

YEARLY

Check water valve lter. Also check water valve lter if water ow into toilet becomes insufcient.

7.3 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

ushing, shut off power to sea water pump and add fresh water by pouring directly into the bowl

during the ush cycle.

2. Flush toilet at least ve 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.

7 Maintenance and winterizing

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.

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.

7.4 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).

Caution

Never use automotive-type antifreeze in freshwater systems.

Note

Use nontoxic antifreeze designated for potable water systems. (See boat or vehicle

owner’s manual.)
