connection (D) to the other end of the

plastic coupling (C); secure with a clamp

(M).

6. Cut off the end of the step-down

rubber connection to ﬁt the 1” pipe;

secure with clamp (M).

Note : Install a ball valve in the discharge

line in order to facilitate the removal of

the unit.

If you want the unit to pump vertically

and horizontally, you may calculate that

3 Ft of vertical lift is equivalent to 30 Ft

of horizontal run. Note that all horizontal

runs require a 1/4" per foot gravity fall.

Each bend or change in direction causes

minor losses which must be deducted

from the discharge performance (i.e.

reduce discharge height by 3 Ft for each

90 degree turn). Use long sweeping 90

degree elbows or two 45 degree elbows

back-to-back to create the 90 degree

turn. Do not use 90 degree elbows.

PREPARING THE

MACERATING UNIT

Follow steps on page 3.

CONNECTION TO

A VENT SYSTEM

The macerating unit must be vented. It

has a 1-1/2” inlet on the top of the cover

meant for this connection. It must be

connected to a vent system according

to your local plumbing codes.

Install the provided 90 degree rubber

elbow (K) on this inlet to connect to the

vent pipe and secure with clamps (N).

Note that all ﬁxtures connected to the

system must also be vented.

Warning : Do not use an air ad-

mittance valve or a mechanical

spring-loaded venting device, as

these devices are one-way valves.

The air pressure in and outside the

macerating unit must be equal.

CONNECTION OF

SANITARY FIXTURES

The macerating unit is equipped with

two additional 2” inlets, one on either

side of the case. These inlets, which

incorporate an internal check valve, are

used to connect the drainpipe of other

sanitary ﬁxtures to the macerating unit.

Use the pvrovided 2” x 2” coupling (J)

when connecting a shower/bathtub

or the 1-1/2” x 2” coupling (I) when

connecting a sink. Secure these

connections with clamps (O, N) once

they are installed.

Note : In case one of the inlets is not

used by a ﬁxture, you will need to block

off this inlet with the plugs provided (R).

Any standard shower stall or bathtub

may be used as only the drainpipe

connects to the macerating system.

Note that when installing either one of

these ﬁxtures, a platform would need to

be built in order to raise the shower or

bathtub.

It is required that when connecting a

shower or bathtub to the macerating

unit, the base of the shower tray

or bathtub, be raised by at least 6”

(recommended 8”) from the ﬂoor. A

platform can be build out of 2” x 8”

lumber on which the tub or shower

tray would be placed.

Note : The actual distance between

the p-trap of the additional ﬁxture

and the macerating unit determines

the necessary clearance to install the

p-trap and elevation required to ensure

a minimum gravity ﬂow of 1/4-inch per

foot. Therefore, the further the pump

is away from the connecting ﬁxture,

the higher the platform would need to

be raised considering the gravity fall

required.

CONNECTION TO THE

ELECTRICAL SUPPLY

All wiring should be in accordance

with the applicable electrical code in

your territory. The macerating system

requires a single-phase 120-volt,

15 amp. supply. When installed in a

bathroom, the receptacle should be 40

inches away (in a straight line) from a

shower or bathtub. Connect only to a

receptacle protected by a ground fault

circuit interrupter (GFCI).

Warning : Risk of electric shock - this

pump is supplied with a grounding

conductor and grounding type at-

tachment plug to reduce the risk of

electrical shock. Be certain that it is

connected only to a properly grounded -

type receptacle.

NORMAL OPERATING

CYCLE

As the ﬂush is operated or as the bath,

shower and lavatory discharge, the water

and waste enter the unit and the water

level begins to rise, triggering the micro-

switch in the pressure chamber. This in

turn activates the motor. The shredded

waste is picked up by the impeller and

discharged through a 3/4" or 1" outlet

pipe to a sanitary sewer or soil stack.

Safety note : For safety, the macerating

unit should never be activated with the

lid removed.

VII

CONNECTION OF THE

DISCHARGE PIPE

These systems are provided with a

discharge elbow which has a built-in

check valve (A), a ﬂexible discharge

hose (B), a plastic coupling (C) and

a step-down rubber connection (D).

Follow these steps to connect to your

discharge pipe.

1. Insert the larger end of the plastic

discharge elbow (A) into the rubber

discharge hose coming out from the top

of the pump.

2. Rotate the discharge to any direction

and secure the base of the elbow with a

clamp (N).

3. Connect the ﬂexible hose (B) to the

smaller end of the discharge elbow and

secure with a clamp (L).

For 3/4" CPVC (22 mm)

4. Insert the discharge pipe inside the

ﬂexible hose (B) and secure with a

clamp (L).

For 3/4" PVC (28 mm)

4. Insert the smaller end of the plastic

coupling (C) inside the ﬂexible hose (B);

secure with clamp (L).

5. Connect the step-down rubber
