3-2-1 Place the macerating pump unit in the desired location and connect all inlet and outlet waste piping to the unit. The
non-inlet side of the tank should be up against the wall to ensure proper toilet placement.
3-2-2 Assemble the toilet in accordance to the installation manuals provided with it.
3-2-3 Place the toilet in front of the macerating tank and slide the accordion style flapper over the discharge port on the
toilet. Do not install a hose clamp yet. Position the toilet such that the toilet tank is about 1 inch from the wall. Mark
the floor through the two holes in the toilet bowl.
3-2-4 Remove toilet and bore 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.
3-2-5 Place the toilet over the holes in the floor. Slip the plastic china protectors over the lag screws. Tighten lag screws (do
not over tighten) and snap plastic cover caps in place. Connect the accordion style grommet on the macerating tank
to the toilet using a hose clamp to secure it.
3-2-6 Connect the toilet to the fill valve using a water supply hose.
3-3 CONNECTION TO THE DISCHARGE PIPE WORK
3-3-1 The macerating unit has a "step-down" coupler. Simply cut off the appropriate portion of the coupler in order to fit it to
the discharge pipe. Use ridged wall pipe, not flexible pipe or hose, as flexible pipe may distort over time. ¾" or 1" pipe
may be used.
3-3-2 Install a "full-port" ball or gate valve and a union in the discharge pipe in order to facilitate the removal of the
macerating pump unit. Place the union or hose connector then the valve at the lower portion of the discharge pipe.
3-4 CONNECTION TO THE SOIL-STACK OR SEWER
3-4-1 The macerating system will pump up to 15 feet, with a ¼" per foot gravity fall (minimum) constantly throughout the
horizontal run to the point of discharge. If you require a vertical lift it should precede any "horizontal" run and should
commence as near as possible to the discharge elbow. Once you have started the horizontal run, you may not
change directions in a vertical manner.
3-4-2 If you wish the unit to pump vertically and horizontally you may calculate 3 feet of vertical lift is equivalent to 30 feet of
"horizontal" run. Each bend or change of direction gives a pressure drop, which must be deducted from the discharge
performance figures in accordance with the usual head loss practice. As an estimate, reduce discharge height by 3
feet for a 90° bend.
3-4-3 The discharge pipe work 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.
3-5 CONNECTION TO ELECTRICAL SUPPLY
3-5-1 All wiring should be done in accordance with the applicable electrical codes. The macerating system requires a
single-phase, 120 volt, 15 amp supply. When installed in a bathroom, the GFCI (ground fault interrupter circuit) outlet
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.
Risk of electric shock. This pump is supplied with a grounding conductor and ground plug type
attachment plug to reduce the risk of electrical shock. Be certain that it is connected only a properly
grounded-type receptacle.
