Caution! Hazard of Flooding

If the toilet uses fresh water for ushing and is connected directly or indirectly to a shore­side 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 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 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 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 wall­mounted 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 0.83 gal. (3.1 liters) per ush and adds

water to bowl after ush; “Dry Bowl” setting uses only 0.21 gal. (0.79 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”, “3/4” and “full tank” indicator lights. Dometic ush switch panel indicates when
electrical power to toilet is activated, and when holding tank is 75% and/or 100% full (depending on
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.
