IMPORTANT ADDITIONAL INFORMATION
INTRODUCTION
I
This drain pump is manufactured in a factory which
is quality certified to ISO 9001 (2000) accredited
by AFAQ. To benefit from the advantages provided
by this new generation system, it is important to
comply with the installation instructions.
GENERAL DESCRIPTION
II
The drain pump unit is a residential/commercial
pumping system for gray water fixtures. It can
simultaneously receive gray water from sanitary
fixtures such as a sink, shower, bathtub ,washing
machine, etc.
Note that the washing machine must be connected
to the pump via an indirect connection (such as
laundry tub or utility sink).
Installed and used correctly, this system will give
consistent and reliable service.
This system must discharge into a minimum 1"
sanitary drain pipe. The systems includes a fitting
that can adapt 1-1/4" and 1-1/2" discharge pipe.
The discharge diameter cannot be larger than
1-1/2" pipe. This system will pump up to 16 feet
vertically and/or 150 Ft horizontally, with a minimum
1/4" per foot gravity fall constantly throughout the
horizontal run to the point of discharge.
INSTALLATION ADVICE
III
1. The unit shall be positioned on the same level
and adjacent to the fixtures.
2. All discharge pipe work must be connected
to the soil stack by an appropriate and approved
connection (a "wye" fitting is preferable). Note that
the connection into a horizontal soil stack shall be
through the top of the pipe.
3. The discharge pipe from the system shall be an
independent line as no other drain pipe shall tie into it.
4. Any initial horizontal pipe run from the unit, prior
to the vertical lift, should not exceed 18 inches.
Note : After the first vertical run, any run afterwards
should be in a horizontal manner with the required
slope. Therefore, you cannot change directions in
an upward vertical manner.
5. Use long sweeping 90 degree elbows or two
45 degree elbows back-to-back to create the 90
degree turn.
6. When the point of discharge into the soil stack
is lower than the base of the unit, a vacuum relief
valve may need to be fitted at the highest point of in
the pipe run in order to avoid siphonage.
7. The unit cannot accept without damage the
disposal of sanitary items such as condoms,
tampons, sanitary pads, cottons swabs, etc.
8. Any drain pipe leading into the pump shall have
a minimum 1/4" per foot gravity fall. Any horizontal
discharge pipe shall also have this minimum pitch.
9. The total run on the discharge pipe shall be no
less than 3 ft (combined) before it drains into a
larger stack.
10. The discharge pipe work should not be installed
with a diagonal upward slope.

NORMAL OPERATING CYCLE
V
As the bath, shower and lavatory discharge, the
water 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
waste water is picked up by the impeller and
discharged through a 1", 1-1/4" or 1-1/2" outlet
pipe to a sanitary sewer or soil stack.
CONNECTION OF THE
VI
DISCHARGE PIPE
These systems are provided with a discharge
elbow which has a built-in check valve (A) and a
step-down rubber connection (A). 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 (B).
For 1" PVC (32 mm)
3. Connect the step-down rubber connection (A) to
the other end of the plastic coupling ; secure with a
clamp (B).
4. Cut off the end of the step down rubber
connection to fit the diameter required (1", 1-1/4"
or 1-1/2"). Note that 1" diameter is preferable.
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 UNIT
VII
Follow steps on page 3.
CONNECTION TO A VENT
VIII
SYSTEM
The 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 rubber connection (J) on this
inlet to connect to the vent pipe and secure with
clamps (B). Note that all fixtures connected to the
system must also be vented.
Warning : Do not use an air admittance valve
or a mechanical spring-loaded venting de-
vice, as these devices are one-way valves.
The air pressure in and outside the unit must
be equal.
