ADVICE
PIPE SUPPORTS
All sanitary pipe work must be
supported, in accordance with the pipe
manufacturer's recommendations.
Avoid dipping or trapping, which may
cause the build up of residual "solids"
and sub- sequent blockage.
BENDS
Where possible long sweeping bends
should be used. Do not use short
elbows. If sweeping 90° elbows are not
available use two 45° elbows to make a
90° turn.
VERTICAL INSTALLATION FIRST
If vertical lift is required, this must
precede the horizontal pipe run.
DIRECTLY VERTICAL
All vertical lifts should rise as directly
above the unit as possible, allowing
only for the need to clear the toilet tank.
Any initial horizontal pipe run from the
unit, prior to a vertical lift should not
exceed 12".
EASY ACCESS
The unit should be accessible and
removable in the event of maintenance
being required. During the installation a
full-port ball valve should be installed at
the base of any vertical discharge pipe
work from the unit to allow easy service
of the unit.
GRAVITY FALL
The unit accepts wastewater by gravity;
it does not "vacuum" in water. All inlet
pipe work must have a positive gravity
fall, ( " per foot). All horizontal piping
/

from the macerating unit must also have
a positive gravity fall to allow free
drainage when the pump stops.
THREE FEET MINIMUM
The macerating unit must be installed at
least 3 feet from the soil stack. This will
allow the macerator to operate for an
adequate period of time to ensure
efficient waste reduction.

SOIL STACK CONNECTION
All discharge pipe work must be
connected to the soil stack by an
appropriate and approved connection.
A "tee" or "y" fitting as shown is
preferable.
NO DIAGONAL "UPHILL" PIPE
RUNS
All discharge pipe work from the unit
should run either directly vertical
upwards from it or in a horizontal plane
(with a small gravity flow) to the point of
discharge. Pipe work should not be
installed with diagonal upward slope
from the unit to the point of discharge.
PIPE WORK
All pipe work should be either copper,
PVC or CPVC (Do not use flexible
pipes). Hangers should not be less than
four feet apart to prevent pipe rattling.
FLUSHING
Macerating systems requires a
minimum of 6 liters (1,6 gallons) of
water to operate satisfactorily.
DISCHARGE
Never discharge directly into an open
drain, fixture, manhole or rainwater
drainpipe. It is illegal for it constitutes a
health hazard. Direct connections into
sanitary waste systems only, shall be
acceptable.
FREEZING
Ensure all pipe work susceptible to
freezing is adequately insulated or
heated. In unheated buildings, the toilet,
piping and macerating unit must be
properly winterized with "RV or
plumbers" anti-freeze or drained
completely.
ELECTRICITY
Before attempting any maintenance or
servicing, the unit must be disconnected
from the power source. The macerating
system must be connected to a Ground
Fault Circuit Interrupter.
