the waste disposer
2. Turn the mounting assembly over and remove the flange
ring from the track on the sink flange. Undo the three
screws holding it together. This will allow the sink flange,
mount ring, and protector ring to separate (fig 3).
Use the flat blade screwdriver as a lever if required.

3. Apply a small amount of plumbers putty to the lip of the sink
flange and position the sink flange into the sink drain hole
ensuring that the rubber gasket on the underside of the
sink flange is firmly in place (fig.4).

4. Approaching from under the sink, slide the protector ring
and mount ring onto the underside of the sink flange. Fit
the flange ring into the track on the sink flange, then tighten
the 3 mounting screws evenly and securely (fig.5).
Ensure that the mounting assembly
connection is fixed securely and
tightly.
No dishwasher connection required
If a dishwasher is not being connected to the waste disposer,
please proceed to step 7.
Connecting to a dishwasher
If you are connecting to a dishwasher, please continue with steps
5 & 6.

underside of the sink
5. Using a blunt instrument (steel punch or wooden dowel),
knock out the entire plug at the end of the dishwasher drain
inlet (as shown in fig.6). Do not use a screwdriver or sharp
instrument. When the knockout plug falls into disposer, you
may remove it or simply grind it up when the disposer is
used. This will not damage the disposer in any way, but
may take some time to grind, over the course of several
uses.

6. Connect the dishwasher drain hose to the dishwasher inlet
pipe on the waste disposer (fig. 6). Use a clamp to ensure a
tight seal. A stepped rubber adaptor (not supplied with the
product) may be required if the diameter of the drain hose
is larger than the diameter of the waste disposer’s inlet
connection.

7. Connect the discharge elbow to the lower outlet on the
waste disposer (fig. 7).
8. Prior to connecting the waste disposer to the mounting
assembly, press firmly down on the rubber splash guard to
check that is firmly fitted onto the neck of the hopper.
9. Lubricate the top lip and angled surface of the rubber
splash guard with liquid soap or petroleum jelly (fig. 8 ).
Please do not remove clamp and
splash guard from hopper. Both
parts are factory installed and
installation ready.

10. Align the discharge elbow up with the waste pipe (refer to
fig.11) so that the waste disposer is correctly positioned,
prior to engaging with the mounting assembly.
11. Guide the waste disposer up to the sink flange (fig. 9).
Engage the groove of the splash guard around the ridge at
the bottom of the sink flange. A slight rocking motion may
be required to help ensure a proper fit.
Fig. 9 Engage the waste disposer
12. While still supporting the body of the waste disposer,
tighten the screw clamp around the rubber splash guard
(fig.10). The waste disposer will now hang by itself.
13. Connect the discharge elbow up with the waste pipe
(fig.11) and tighten the slip nut on the drain pipe.
If you need to rotate the waste
disposer to connect with the waste
pipe, it is important to make sure
the sink flange does not turn.
Movement of the sink flange will
break the seal created when
installed. If this occurs, disengage
the waste disposer from the
discharge elbow and mounting
assembly Return to step 10 to
realign the waste disposer before
repeating steps 11-13.
Ensure that the reset button is
readily accessible after installation
of the waste disposer.

Installing the air-switch (optional)
1. Select a location on the bench top for the air switch to be
positioned (recommended position is near the sink). Mark
and cut a hole, 33mm in diameter, in the bench top.
2. Remove the nut from the thread of the air switch (fig.12).
3. Feed one end of the PVC tubing up through the cutout,
from the underside of the bench top, and attach to the
underside of the push button.
4. Insert the push button into the bench top cut out (fig.12).
Feed the PVC tube through the nut. Screw the nut onto the
thread tightly (fig.13), securing the push button tightly onto
the bench top.
Do not use a wrench to tighten the
nut.
5. Connect the other end of the PVC tubing to the air switch
outlet, located on the underside of the waste disposer
(fig.14).

Controlling the waste disposer by a wall mounted switch
The waste disposer can be controlled by means of a wall mounted switch rather than the bench mounted air switch
supplied with the product.
To use an existing wall mounted switch:
1. Connect one end of the PVC tubing to the underside of the air switch button.
2. Connect the other end of the PVC tubing to the air switch outlet on the underside of the waste disposer (as
shown in fig.14).
3. Press the button on the air switch to activate the waste disposer.
4. Whilst the waste disposer is running, disconnect the PVC tubing from the air switch outlet on the underside of
the waste disposer.
5. Turn the waste disposer off using the wall mounted switch. The waste disposer can now be turned on and off
using the wall mounted switch.
