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.
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.
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.
VERTICAL INSTALLATION FIRST
If vertical lift is required, this must precede the horizontal pipe
run.
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,
(
1
/
4
» per foot). All horizontal piping from the macerating unit
must also have a positive gravity fall to allow free
drainage when the pump stops.
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.

MAINTENANCE
A visual check of the lift station must be made once a month
to make sure it is operating correctly, and the installation must
be inspected regularly (once a year) by a qualified person.
Meanwhile if encounter technical problems, please ask our
after-sales service for advice. If the power supply cable of the
unit is damaged, it must be replaced by the manufacturer or its
after-sales service to avoid all danger.
