The Sanistar is a combination
of a vitreous china toilet bowl and macerator/pump built into one compact
unit. The Sanistar needs no gravity flow tank as the flushing action and
macerating pump cycle is automatic after pressing a push button on top of
the bowl. The flushing mechanism is electrically timed to allow water to
pass through the toilet.
the push button, this activates a timer and a solenoid valve in order to
fill and wash the sides of the bowl. The motor starts and the waste and
paper are sucked inside, where it is macerated and pumped away. The motor
stops after approximately 10-15 seconds and the timer programs the refill of
the bowl with fresh water.
The standard dual flush version uses 1.28
gpf (4.8 lpf) and 1 gpf (3.8 lpf). To choose either option, the unit is
provided with a dual push button. This option allows using less water than
any regular toilet but with the same efficiency.
The inside of the Sanistar comprises of a
pressure switch and circuit board assembly, which starts and stops the unit,
and the motor, which drives the blade and the pump. The motor is sealed for
life in an oil filled enclosure. A common spindle/shaft drives the impeller
and the macerator blades. The moving parts therefore are kept to an absolute
minimum. Water and organic waste matter, enter the chamber and are reduced
to slurry as the macerator blades rotate at 3600 RPM. The reduced solids are
picked up and the impeller mounted beneath the motor ejects the waste. The
unit pumps the effluent upward to 9 feet and/or 100 feet horizontally (with
The discharge elbow on the back of the
Sanistar can be rotated 360 degrees to fit any type of installation
required. A non-return valve, which comes already assembled on the discharge
elbow, prevents back flow into the unit.
The Sanistar is a forced main and does not
need to vented and connected to a vent stack. Other fixtures may need to be
vented as per local plumbing codes.
It is also highly recommended for the
macerator/pump to be connected to a Ground Fault Interrupter (GFI) circuit.
The Sanistar is composed of a
toilet bowl and motor assembly. It comes with the toilet seat and metal
frame to mount the toilet bowl to the wall.
