Installation
The pump shall be plugged into a properly fused electrical
outlet with a ground fault circuit interrupter (GFCI) that
conforms to current National Electric Code (NEC) and all
applicable local codes. All wiring must be performed by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code
®
, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
Note to Installer:
During installation, it is best to cover the
macerating unit with plastic to protect it from potential leaks at
the toilet fill connection or tank to bowl gasket.
Refer to Figure 1 Typical Applications as needed during the
installation process. Installations may vary per local plumbing and
electrical codes. Also, discharge and vent pipe routing can vary
per installation.
1. Place the macerator in the desired location and connect all
inlet and outlet waste piping to the unit. The inlet side should
be facing the toilet to ensure proper placement. Refer to
2. Assemble the toilet in accordance with the installation
manual(s) provided with it. Be careful when tightening
fasteners as to not crack the porcelain.
Figure 4. Placement Options
Figure 5. Toilet Connections
1. To mount the toilet to a concrete floor, drill two holes
approximately 2-1/4” deep with a 5/16” masonry drill bit.
Insert plastic plugs into holes. If the floor is wood, bore a pilot
hole with a 1/4” drill bit. Fasteners not included.
2. Toilet to macerator connection:
a. Standard Installation:
Place the toilet in front of the
macerating tank and apply
silicone grease (supplied) to the
rubber sealing lip of macerator.
Then slide the discharge hub of
the toilet into the rubber
sealing ring of the macerator.
b. Behind Wall Installation:
To install the macerator behind a wall, an Extension Pipe Kit
(K001184, sold separately) is needed. Included in the kit
are an 18-3/4” 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 discharge, and then insert
the pipe into the macerator.
Liberty Pumps recommends using only one extension pipe.
