INTRODUCTION
1.1 - GENERAL DESCRIPTION
The macerating unit is a residential pumping system for toilet
and bathroom fixtures. The system is comprised of three major
components :
- the macerating unit, which connects to the outlet of a
rear spigot outlet toilet
- The toilet bowl
- The toilet tank
The macerating unit also consists of three major parts: the
container which houses the operating mechanism; a pressure
chamber which automatically activates and deactivates; the
induction motor which drives the cutting blade and the impeller.
The macerating unit can simultaneously receive wastewater
from several sanitary fixtures, e.g. bidet, hand basin, shower,
bathtub, urinal, but only one water closet per unit.
Macerating units are designed for the disposal of human
waste, toilet paper and water. They are not intended to be
used for the disposal of kitchen waste, neither are they
intended to be used for the disposal of waste water from such
pump appliances as dishwashers and clothes washers.
However these appliances can be connected to the Sanibest
(not to a Saniplus), provided that they drain first into a laundry
sink Sanitary fixtures connected to the macerating system
must be located on the same level.
Macerating system must discharge into a minimum 3/4-inch
sanitary drainage pipe. The macerating system will pump up
to 15 feet for Saniplus, 18 feet for Sanibest vertically, with
a / " 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 cannot change
directions in a vertical manner.
SANITARY INLETS
The macerating unit is equipped with two additional 1
(SANIBEST) or 2" (SANIPLUS) 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.
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.
BATHTUB
Any regular bathtub can be used, as only the drainpipe
connects to the macerating unit. When installing a
bathtub, we recommend to build a platform out of
2 x 8-inch lumber, on which the tub is placed. This gives
enough space for a p-trap and slope toward the
wastewater inlets.
SHOWER STALL
When installing a shower a special raised shower base
may be purchased, This eliminates the building of a
platform. Alternatively, you may want to purchase a
regular shower and also build a platform for it. We
recommend to build a platform out of 2 x 8-inch lumber.
Note: Platform height. 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 / -inch per foot.

1.2 - 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 pump and discharged through a
/ " outlet pipe to a sanitary sewer or soil stack.

Safety note: For safety the macerating unit should never be
activated with the lid removed.

INSTALLATION
2.1 - PREPARING THE MACERATING UNIT
Push the elbow into opening, in the same direction as the
outlet. Push rubber elbow onto the shoulder and secure with
a gearclamp.
2.2 - CONNECTION OF THE OTHER SANITARY
APPLIANCES
Saniplus : See page 3 drawing 7b
Sanibest : See page 6 drawing 7b
• To connect to the side entries of the case, use the side
connector. Secure with clamps.
• Plug the unused inlet with blanking plug after greasing the joint.
Warning: Ensure when connecting a shower to the macerating
unit that the underside of the shower tray is raised by at least
7 inches from the floor.
2.3 - WATER CLOSET ASSEMBLY
The tank comes with the fill and flush valve assembled, however,
please ensure that all screws, nuts, etc. are tightened
2.4 - SYSTEM ASSEMBLY
Saniplus : See page 3 drawing 7a
Sanibest : See page 6 drawing 7a
1. Place the macerating unit in the desired spot and connect
all inlet and outlet waste piping to the unit. (See Connection to
discharge pipe work).
2. Place the spigot outlet of the toilet bowl firmly against the
white accordion connector and mark the floor through the
holes in the bowl.
3. Remove bowl and bore two holes approximately 2
with a / " masonry drill bit. Insert plastic plugs into holes. If

the floor is wood, bore a pilot hole with a
4. Place the bowl in front of the macerating unit and pull the
accordion gasket all the way onto the rear spigot outlet. Attach
with supplied gear clamp. Check that gasket and clamp are
even all around.
5. Move the bowl over the holes in floor. Slip the plastic china
protectors over the lag screws.Tighten lag screws (do not over
tighten) and snap plastic cover caps in place.
6. Locate the tank to bowl kit and place foam gasket on the
spud of the flush valve and over nut. Place tank on top of the
bowl. Insert screws and gasket through the tank and tighten
nuts underneath. Do not overtighten as this may damage the
china.
2.5 - CONNECTION TO WATER SUPPLY
Connect the water supply hose to the fill valve.
2.6 - CONNECTION TO THE DISCHARGE PIPE WORK
These macerating units have an elbow, and a "step-down"
bushing simply cut off the appropriate portion of the bushing 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.
Use / " discharge pipe.

Optional : install a "full-port" ball or gate valve and a union in
the discharge pipe in order to facilitate the removal of the
macerating unit. Place the union or hose connector then the
valve at the lower portion of the discharge pipe.
If you wish the unit to pump vertically and horizontally you may
calculate that 3 feet of vertical lift is equivalent to 30 feet of
"horizontal" run.
Each bend or change of direction causes minor losses, which
must be deducted from the discharge performance figures in
accordance with the usual head loss practice. (Rough guide:
reduce discharge height by 3 feet for each 90° bend).
