Frequently Asked Questions - Masterflush MF7200 DOMETIC

How to start the flush system?

Open the water supply, then press the Flush button (2) for at least 10 seconds. Throw in toilet paper to test discharge.

How to perform a normal flush?

Press the Flush button (2) until complete discharge (10-20 seconds). For liquids, press less to save water.

How to add water to the bowl?

Press the Water addition button (1) until desired level. Do not press too long to avoid overflow.

How to use sea water flush?

Open the sea water inlet and drain valves. Use the Flush button (3) the same way as for fresh water.

What to do if water drains slowly or not at all?

Check that the drain pipe is not compressed or bent (max height 1.2 m). Unclog the pump or pipe if necessary.

The macerator pump is making unusual noise, what to do?

Close the valves, then remove any foreign object from the pump chamber. If the problem persists, contact customer service.

The flush cycle does not activate, possible causes?

Check that the waste tank is not full (disconnect signal). Check the power supply, fuses, flush button, and motor.

Why is water intake insufficient or nonexistent?

Check the supply line, unclog the strainer or water filters. Replace water valve (fresh) or impeller (sea) if defective.

How to store the toilet for prolonged inactivity?

Flush, add 118 ml of biodegradable detergent (no bleach), flush 5 times. Turn off water and power. For sea water, use fresh water during flushing.

What type of toilet paper to use?

Use fast-dissolving toilet paper (e.g., SeaLand®). Test: dip a square in water and shake; it should tear apart and not remain whole.

MasterFlush Operation

Freshwater Flush

Toilet system start-up

1. Turn on fresh water supply to toilet.
2. Press "Flush" switch (2) and hold for at least 10 seconds.
3. Toss several sheets of toilet paper into bowl and repeat cycle. The bowl should completely clear.

Normal flushing

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.

FLUSHING TOILET

Press "Flush" switch (2) down and hold until waste drains from toilet bowl (about 10 - 20 seconds). This switch activates a macerator pump that siphons water and waste from the bowl, macerates, and propels the effluent to the discharge line/holding tank.

To use less water for liquid-only flushes, press "Flush" switch for shorter period of time.

Sea Water Flush

Toilet system start-up

1. Open sea water inlet and toilet discharge outlet seacocks.
2. Press "Flush" switch (3) and hold for at least 10 seconds.
3. Toss several sheets of toilet paper into bowl and repeat cycle. The bowl should completely clear.

Normal flushing

Press "Flush" switch (3) down and hold until waste drains from toilet bowl (about 10 - 20 seconds). This switch activates a macerator pump that siphons water and waste from the bowl, macerates, and propels the effluent to the discharge line.

To use less water for liquid-only flushes, press "Flush" switch for shorter period of time.

If toilet bowl does not completely flush and fills up with sea water during flush, partially close inlet valve until bowl clears and completely discharges effluent. Then, with inlet and discharge valves completely open, flush toilet for a few seconds to clear toilet and discharge system.

Caution! Hazard of Flooding

If toilet is connected to ANY through-the-hull fittings, ALWAYS close sea-cocks 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.

DO NOT FLUSH FOREIGN OBJECTS

CAUTION! Flush only water, bodily wastes and rapid-dissolving tissue paper. Do not flush wet wipes, sanitary napkins, condoms, diapers, razor blades, paper cups, cotton swabs, food, hair or liquids such as oils or solvents. Clogging or damage to the toilet system may occur.

Note

Make sure all guests understand toilet operation before use.

Use RAPID-DISSOLVING toilet tissue - avoid clogs

To avoid potential clogging problems with some household tissues, Dometic recommends the use of quick-dissolving tissue, such as SeaLand® Rapid-dissolving 1-ply or 2-ply Toilet Tissue.

IMPORTANT! NOT EVERY MARINE-GRADE TOILET PAPER DISSOLVES RAPIDLY

To determine any tissue's ability to dissolve, immerse one square of tissue in a jar of water and shake 5-10 times. The tissue sample should break up so that it is no longer in one piece.

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 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 directly into the bowl during the flush cycle.

1. Flush toilet at least five times.
2. Turn off water supply to toilet.
3. Flush the toilet without water very briefly to evacuate all water. (This procedure will minimize any remaining water in the macerator pump.)

Caution

During water evacuation process, do not operate sea water pump very long without water. Pump impeller may become damaged.

1. Turn off power to the toilet.
2. After extended periods of non-use, toilet and pump may dry. For easier re-start of toilet system, add one quart of water to bowl and let it stand for a few minutes before use.
