GRAVITY FALL
Horizontal discharge pipe work must also
have a positive gravity fall to allow free
drainage when the pump stops.
THREE FEET MINIMUM
The macerating/pump must have at least
3 feet of total pipe run in between the
pump and soil stack. This will cause the
macerator to operate for an adequate
period of time to ensure waste reduction.
SOIL STACK CONNECTION
This unit must discharge into a minimum
3-inch sanitary drainage pipe.All discharge
pipe work must be connected to the soil
stack by an appropriate and approved TY
connection. Please note: the use of a
Saddle Clip may be prohibited in your
area.
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.
VII
ADVICE
PIPE SUPPORTS
All sanitary pipe work must be
supported, in accordance with the
pipe manufacturers recommendations,
to avoid dipping, which may cause
the build up of residual water and
subsequent blockage.
BENDS
Where possible long sweeping bends
should be used. Do not use short
straight elbows. If sweeping elbows are
not available, use two 45 degree elbows
back-to-back to make a 90 degree turn.
VERTICAL INSTALLATION FIRST
If vertical lift is required, this must
precede the horizontal pipe run. The
vertical discharge pipe should first bypass
the bowl, do not extend the horizontal
portion of the pipe for more than 12-18
inches.
EASY ACCESS
The unit should be accessible and
removable in the event of maintenance
being required. During the installation a
full-port gate valve should be fitted at the
base of any vertical discharge pipe work
from the unit to allow easy removal of the
unit without flooding.
PIPE WORK
All pipe work should be either copper or
solvent weld plastic (PVC, CPVC). Do not
use flexible pipes.
DISCHARGE
Never discharge directly into an open
drain, manhole or rainwater drain pipe.
It is illegal.
FREEZING
Ensure all pipe work susceptible freezing
is adequately insulated. The toilet and
macerating/pump unit must be properly
winterized in unheated buildings.
ELECTRICITY
Before attempting any maintenance
or servicing, the unit must be
disconnected from the power source.
The SANICOMPACT® 4 must be connected
to a Ground Fault Circuit Interrupter and
be supplied with 120V, 60Hz.
