OPERATION

The Quiet-Flush Toilet Conversion provides both quiet
operation and user control of water levels in the toilet
bowl. A single large pushbutton switch provides a simple
flush mode by activating both the rinse water supply and
the macerator discharge pump simultaneously. An addi-
tional rocker switch offers independent control of the
rinse water supply and discharge pump separately so
the bowl water level can be easily raised or lowered by
the user. This provides a method of minimizing water
use, when desired, as well as a means of raising the
Model 37255-Series
water level in the bowl when appropriate for user com-
fort. It also allows for complete evacuation of the bowl
water while underway in rough sea conditions.

INSTALLATION

The 37255-Series Quiet-Flush Toilet Conversion is com-
plete with a dedicated PAR-MAX 4 pump to provide either
sea or lake water to rinse the toilet bowl when flushing the
toilet. This pump is intended to be located remotely from
the toilet but will function best if the distance from the toi-
let is kept to a minimum. Because it is self-priming, it may
be located above the vessel's waterline. It must be
installed with the Pumpgard strainer (provided with the
toilet) located somewhere in the inlet plumbing to the
pump. The toilet also includes a multi-function flush con-
trol which should be installed in a bulkhead location that
is convenient to the toilet and allows access for wiring to
run from the power source and to both the toilet dis-
charge pump and the PAR-MAX rinse water pump.
Before beginning the conversion, close all seacocks con-
nected with the toilet's plumbing system and take pre-
caution to ensure they remain closed until the conver-
sion is complete. If the toilet being converted is an elec-
tric toilet, disconnect the electrical power to the toilet and
take precaution to ensure it is not restored until the con-
version is complete.
Disconnect both inlet and discharge hoses from the old
toilet and remove the toilet from its mounting surface. If
the toilet being converted is an electric model, discon-
nect the electrical wiring from the toilet. Remove the
hose connected to the back of the toilet's china bowl and
remove the china bowl and seat & lid assembly from the
old toilet base assembly. Ensure the bottom surface of
the china bowl is clean.The waste pump can be oriented
in any of the four possible mounting positions that pro-
vides the best clearance from surrounding obstructions
but is generally best positioned so it points to the rear of
the toilet bowl. The four 6 mm machine screws must be
