1 Notes on using the manual

Caution!

Safety Instruction: Failure to observe this instruction can cause material damage and impair the function of the device.

Note

Supplementary information for operating the device.

fig. 1 A, page 2: This refers to an element in an illustration. In this example, item A in figure 1 on page 2.

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 influences, 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 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 qualified 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 INJURY OR DEATH TO PERSONNEL 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 disconnected 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 possibility, 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 8100 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, the toilet allows the user to add water to the bowl (before or after flushing) and to flush the toilet by pushing a button.

3.1 Benefits

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

Choice of two water consumption settings. “Normal” flush adds water to bowl while button is pushed; “Dry Bowl” does not use water during a flush – it only operates the macerator pump.

Versatile installation. Powerful macerator pump allows toilet to be located up to 98 ft. (30 m) away or 9.8 ft. (3 m) below holding tank or other discharge line destination.

Automatic “full tank” shut-down (Optional installation - tank level monitor and shut-down relay required. Available separately). When connected to a holding tank level indication system, the 8100 series toilet system will shut off electrical power to the toilet when the holding tank is full. This safety feature prevents overfilling the holding tank, which may cause damage to the boat.

6 Operation

6.1 Toilet system start-up

1. Turn on water supply to toilet.
2. Press "Flush" switch (2) and hold for at least five seconds.
3. Toss several sheets of toilet paper into bowl and repeat cycle. The bowl should completely clear.

6.2 Normal toilet operation

ADDING WATER TO TOILET BOWL

Press “Add Water” switch (1) and hold until desired water level is achieved. (Do not press “Add Water” switch too long or overflow may occur.) More water is usually added only when flushing solids.

Close-up of a black industrial control panel with three labeled buttons (1, 2, 3) and icons, no readable text or symbols beyond labels.

FLUSHING TOILET

Press “Flush” switch (2) down and hold for a few seconds after waste drains from toilet bowl (about five seconds). This switch activates a powerful macerator pump that siphons water and waste from the bowl, macerates, and propels the effluent through the discharge line/holding tank. To use less water for liquid-only flushes, press “Flush” switch for shorter period of time.

During periods of rough travel, water in a toilet bowl can splash out and into the bathroom area. To avoid this situation, press "Dry Bowl" switch (3) to drain water completely from toilet bowl. Water is not added to bowl during or after pressing the "Dry Bowl" switch.

Caution – Do Not Flush Waste with "Dry Bowl" Switch!

To maintain proper cleanliness and operation of the toilet and macerator pump, water should be used with every flush.

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.

6.3 Toilet operation when connected to "full tank" shut-down relay and tank monitor system

When a Dometic 8100 series macerator toilet system uses a “full tank” shut-down relay, electrical power to the toilet is shut off when the holding tank level reaches “full”. To restore electrical power to the toilet for flushing, holding tank contents must be emptied or discharged until the “full” tank indicator is not activated.

7 Maintenance and winterizing

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.

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.

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 filters and vented loops for blockage.

YEARLY

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

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 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.

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).

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: • Hose that fits raw water pump, about 3 ft. (1 m) long

- one container

1. Close intake and discharge seacocks. See Hazard of Flooding risks in this manual.
2. Turn off power to toilet.
3. Disconnect and drain intake hose and in-line filters.
4. Connect hose to raw water pump intake.
5. Place hose connected to pump intake into bucket with antifreeze in it.
6. Turn on power to toilet and flush until antifreeze is removed from toilet.
7. Disconnect power to toilet and reconnect all intake and drain hoses.
