PLUMBING
Operated by a wall-mounted flush switch or electronic
flush handle, the toilet allows the user to add water to the
bowl (before using or flushing) and to flush the toilet by
pushing a button. The Dometic flush switch panel includes
lights to indicate when electric power to the toilet is
activated, and when the holding tank (if applicable) is full.
For information regarding the motion-sensor (hand wave)
switch panel installed on some Dometic 8000 and 9000
series toilets, refer to the Electronic Flush Switch Panel
article in Newgle.
Dometic macerator toilets use a Dometic control module
and a wall-mounted flush switch, which can be located in
a basement compartment, cabinet, or on the floor (behind
the toilet). The module will be located no more than 6 feet
from the toilet. The module has power, ground, two tank
level warning wires, and a communication cable.
Adding Water To The Toilet
Bowl
Press the “Add Water” switch until the desired water level
is achieved. The 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 The Toilet
Press “Flush” switch, then release it. This activates a
powerful macerator pump that siphons water and waste
from the bowl, macerates, and propels the effluent
through the discharge line to the holding tank.

Changing Flush Modes
Dometic 8700 series MasterFlush toilets offer two flush
settings to help manage water consumption:
1. Normal Flush: Uses 0.85 gallons per flush and adds
water to bowl after ever flush.
2. Dry Bowl Flush: Uses 0.45 gallons per flush and does
not add water to bowl after flush.
To change from Normal to Dry Bowl flush setting, press
the “Flush” switch for about five seconds. When the
“Power On” light begins flashing, release “Flush” switch.
The flush mode has been changed to Dry Bowl setting.
Change the mode to Normal flush by following the same
procedure.
Indicator Lights
•
“Power On” Indicator: On the Dometic flush switch
panel, as steady green “Power On” light indicates
when electrical power to the toilet is activated. A
momentary flashing green light indicates when flush
mode is changing.
•
Tank Level Indicator: The flush switch panel includes
a bi-color “3/4 Full” (amber) and “Full” (red) Tank
Level light to indicate when the holding tank is
approximately 75% or 100% full 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.
