3-3 SYSTEM ASSEMBLY
3-3-1 Schematics: Typical Installation Diagrams. Refer to these diagrams when needed during the assembly process. Installations may
vary per local plumbing and electrical codes. Also, discharge and vent pipe routing can vary per installation.
3-3-2 Place the macerator in the desired location and connect all inlet and outlet waste piping to the unit. The non-inlet side of the tank
should be towards the wall to ensure proper toilet placement.
3-3-3 Assemble the toilet in accordance to the installation manual(s) provided with it. Be careful when tightening fasteners as to not crack
the porcelain.
3-3-4 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 ¼" drill bit.
3-3-5 Place the toilet in front of the macerating tank and apply silicone grease to sealing lip of macerator. Then slide the discharge hub of
the toilet into the rubber sealing ring of the macerator.
3-3-6 Place the toilet over the holes in the floor. Slip the plastic china protectors over the lag screws ensure proper orientation. Tighten lag
screws (do not over tighten) and snap plastic caps in place.
3-3-7 Connect the water supply line to the fill valve, located directly below the flush lever, on the bottom of the toilet tank.
3-4 CONNECTION TO THE DISCHARGE AND VENT FLANGES
3-4-1 The Macerator has a PVC discharge flange with an integrated check valve that can be configured in a vertical or horizontal
orientation. Standard 1" schedule 40 PVC pipe can be solvent welded directly to the flange. Excessive amounts of glue should be
avoided. The check valve can be removed from the flange if required. Replacement flanges can be ordered.

3-4-2 A "full-port" ball or gate valve and a union should be installed in the discharge pipe to facilitate the removal of the macerator or to
perform maintenance if required. In addition, a drain off point is also recommend to allow the discharge piping to be drained if
required.
3-4-3 The macerator is equipped with a PVC vent flange, which can be configured in a vertical or horizontal orientation. Standard 1-1/2"
Schedule 40 PVC pipe can be solvent welded directly into the flange.
3-4-4 The macerator must be vented to allow for proper toilet flush performance. Depending on the installation, the product should either
be connected to the stack vent of the dwelling or vented (plumbed) directly outside.
***Do not use an air admittance valve or a mechanical spring-loaded venting device
3-4-5
valves. The air pressure in and outside the macerating pump unit must be equal, a "cheater" vent will obstruct the airflow in one
direction and prevent proper toilet function.
3-4-6 The Macerator is not designed to support the discharge and vent piping; proper pipe hangers are required.
3-5 CONNECTION TO THE SOIL-STACK OR SEWER
3-5-1 The macerator has a shut-off head of 36 feet. All frictional losses from horizontal runs and elbows need to be accounted for. The
minimum flow rate for 1" PVC sch. 40 pipe is 5 gal/min compared to 3 gal/min for ¾" PVC pipe. If you require a vertical lift, it should
precede any "horizontal" run and should commence as near as possible to the discharge of the macerator. Once you have started
the horizontal run, you may not change directions in a vertical manner.
NOTE: Friction losses from horizontal runs without ¼" per foot pitch will reduce the amount of vertical lift
the system is capable of handling. See sections 3-5-2 and 3-5-3. Consult factory for proper sizing if you
have long runs or multiple elbows. Phone: 1-800-543-2550.
3-5-2 The discharge piping can be made from ¾" or 1" diameter CPVC or PVC pipe. Use long turn bends and not elbows where possible.
The connection to the soil-stack or sewer pipe should be made with an approved wye fitting.
