OPERATION
The Quiet-Flush toilet provides both quiet operation and
user control of water levels in the toilet bowl. A single
large push button switch provides a simple flush mode
by activating both the rinse water supply and the macer-
ator discharge pump simultaneously. An additional 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 water level in the bowl when
appropriate for user comfort. It also allows for complete
evacuation of the bowl water while underway in rough
sea conditions.
INSTALLATION
PLUMBING
The toilet can be plumbed to any pressurized water system
that can provide a minimum of 3-1/2 GPM (13.5 LPM).
This may be a fresh water system including the vessel’s
potable water system or a washdown system utilizing
either fresh or salt water. However, it must be connected
to a pressurized system that normally remains on at all
times while the vessel is in use.
To make the water connection, shut off the water system
pump and open one of the systems faucets or fixtures to
drain the pressure from the system. Select an appropriate
tee type fitting that can be installed in the existing
pressurized water system and will provide a 1/2"
(13mm) hose barb to feed water to the toilet. Install the
tee fitting at a location on the pressurized water system
that provides convenient connection to the toilet’s
solenoid valve/ siphon breaker assembly. If the toilet is
being connected to the vessel’s fresh water system and
the vessel may be connected to an unregulated city
water supply, it is recommended that a valve be installed
in the toilet water supply line ahead of the solenoid
valve/siphon breaker to regulate the flow rate of
incoming pressurized city water.
