3-6 CONNECTION TO ELECTRICAL SUPPLY
3-6-1 All wiring should be done in accordance with the applicable electrical codes. The macerating system requires a properly sized
single-phase GFCI (ground fault circuit interrupter) type receptacle. Receptacle should be installed in accordance with local and
state electrical codes. It is recommended that the receptacle be 40 inches away (in a straight line) from a shower or bathtub. If
installation is performed in a basement, the receptacle should be 48 inches from the floor.
3-6-2 If the electrical power receptacle (outlet) is in close proximity to the macerator, the "extra power cord" can be coiled and tucked
away in a large depression designed into the access cover that is located under the right decorative cover.
Risk of electric shock. This pump is supplied with a
grounding-type attachment plug. To reduce the risk of
electric shock, be certain that it is connected to a
properly grounded, grounding-type receptacle.
3-7 EXTENSION PIPE
3-7-1 To install the macerator behind a wall, a Liberty extension pipe kit # K001184 (sold
sperately) will be needed. Included in the kit are an 18.75" long extension pipe, a
decorative trim ring, and a grease packet. Rubber rings seal both ends of the extension
pipe. To prevent tearing, always grease both seals prior to installing the pipe. Slip
the decorative trim ring onto the pipe. To install the pipe, no fasteners are required, slip
the extension pipe over the toilet's discharge, and then insert the pipe into the
macerator. To finish the installation, fasten the toilet to the floor and secure the
macerator discharge and vent piping. For proper flushing performance, ensure that the
base of the toilet is not below the base of the macerator. Check the extension pipe with
a level, and verify that the pipe is either level or sloped towards the macerator unit and
away from the toilet.
3-7-2 Liberty recommends only one extension pipe be used.
3-8 INSTALLATION TIPS
3-8-1 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 buildup of residual "solids" and subsequent blockage.
3-8-2 BENDS: Wherever 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.
3-8-3 VERTICAL PIPING FIRST: If vertical lift is required, this must precede the
horizontal pipe run.
3-8-4 BATTERY: Battery must be installed AFTER the macerator is connected to the
AC power supply. Failure to follow this procedure could result in the unit not
functioning properly.
3-8-5 DIRECTLY VERTICAL: All vertical lifts should rise as close to the macerator
as possible, allowing only for the need to clear the toilet tank; the initial horizontal run should not exceed 12".
3-8-6 NO DIAGONAL "UPHILL" PIPE RUNS: All discharge piping from the unit should run either directly vertical or in a horizontal plane
(with a minimum ¼" per foot drop) to the point of discharge. Pipe work must not be installed with a diagonal upward slope from the
unit to the point of discharge.
3-8-7 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 near the discharge flange to allow easy service of the unit.
3-8-8 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 drop minimum). All horizontal piping from the macerator must also have a ¼" per foot drop to allow free
drainage when the pump stops.
3-8-9 SOIL STACK CONNECTION: All discharge pipe work must be connected to the soil stack by an appropriate and approved
connection like a "tee" or "y" fitting.
3-8-10 PIPE WORK: All pipe work should be copper, PVC, or CPVC. Do not use flexible piping. Hangers should not be less than 4 feet
apart to prevent pipe rattling.
3-8-11 FLUSHING: Macerator is designed to work with a low flow toilet (1.28 gallons per flush).
3-8-12 DISCHARGE: Never discharge directly into an open drain, fixture, manhole or rainwater drainpipe. It is illegal, as it constitutes a
health hazard. Direct connections into sanitary waste systems only shall be acceptable.
3-8-13 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. Use plumbers' anti-freeze or drain completely.
3-8-14 ELECTRICITY: The macerating system must be connected to a Ground Fault Circuit Interrupter (GFCI).
Before attempting any maintenance or servicing, the unit must be disconnected from the power source.
3-8-15 SHOWER: The water height will be 4.5" in the Macerator tank before the unit starts pumping. The shower stall floor must be well
above this level, Liberty recommends at least 6" - 8" to ensure proper shower drainage and prevent any backflow.
