Loosen the clamp screw to allow the mounting system to be  
removed from the unit (fig.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).

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).  
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).  
Fig. 3 Disassembling the  
mounting system  
Note:  
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.

sink drain hole  
Connecting to a dishwasher  
If you are connecting to a dishwasher, please continue with  
steps 5 & 6.  
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.

engaging with the mounting assembly.  
Fig. 8 Lubricate the rubber  
splash guard  
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.  
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.  
Fig. 9 Engage the waste disposer  
13 Connect the discharge elbow up with the waste pipe (fig.11)  
and tighten the slip nut on the drain pipe.  
Note:  
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. 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.

Operating instructions  
Operating instructions  
1
Remove the sink stopper and turn on a medium flow of cold water.  
Note:  
Do not use hot water. Only cold water should be run through the waste disposer.  
2
3
Press the air switch or the wall mounted switch to activate the waste disposer.  
Feed food items through the sink opening of the waste disposer gradually.  
Note:  
Overloading the waste disposer with too much food waste at once may cause the blades to jam  
and the disposer to shut down. The overload button may be required to be reset. Refer to the  
Overload Reset button section on page 9.  
Caution!  
Do not put hands or fingers into the waste disposer.  
4
Before turning the waste disposer off, let the water and the disposer run for approximately half a  
minute after shredding stops. This assures that all the food waste is thoroughly flushed through  
the trap and drain.  
Helpful Hints  
If a dishwasher drain hose has been connected to the waste disposer, be sure that the waste  
disposer’s chamber is empty before using the dishwasher to ensure the dishwasher is able to  
drain properly.  
It is recommended to leave the stopper in the drain when the disposer is not in use to prevent  
utensils and foreign objects from falling into the waste disposer.  
The waste disposer is designed to give you years of trouble-free service. The grind mechanism is  
built to handle all normal food wastes, but WILL NOT grind and dispose of items such as tin cans,  
bottles, bottle caps, glass, china, leather, large bones, mussel or oyster shells. These are waste  
materials that should be collected with your household rubbish.  
We recommend cutting or breaking up items which require considerable grinding time, such  
as melon rinds, grapefruit skins, bones and corn cob husks or dispose of these items with your  
household waste collection.

Cleaning and maintenance  
Your waste disposer is self-cleaning and scours itself with each use. Under normal usage, your  
waste disposer will not require any special care.  
Note:  
Always run cold water into the chamber before, during and after using the waste disposer.  
Do not use hot water.  
Removing an odour  
Grinding up a tray of ice cubes will help to clean the shredding plate.  
Running orange or lemon rinds through the waste disposer will help to freshen up the  
grinding chamber.  
Note:  
Do not pour bleach or drain cleaners, into the waste disposer  
Never put corrosive substances or chemicals into the waste disposer.  
Unblocking a jam  
Before investigating a blockage, you MUST disconnect the power supply.  
The waste disposer is magnetic. ALWAYS use non-magnetic tools, such as a wooden spoon  
or long handled plastic tongs when attempting to loosen a jam or remove an object from the  
waste disposer.  
1
2
After clearing the blockage or jam, turn the power back on , turn on a medium flow of  
cold water and run the waste disposer for half a minute to ensure that all the food waste is  
thoroughly flushed through the trap and drain.  
3
Note:  
If the motor does not start when activated, refer to the Overload Reset Button section below or  
the Troubleshooting guide on page 9.  
Overload Reset button  
The waste disposer is fitted with an overload control which prevents the motor from operating  
should overloading occur. Overloading occurs when the motor is unable to turn, usually caused  
by a foreign object falling in to the chamber or too much food waste being fed through into the  
chamber at once, jamming the shredding plate.  
When overloaded the motor will stop automatically. To restart the motor the overload reset  
button must be pressed.  
The reset overload button is a small red button located opposite the power cord outlet, near the  
bottom of the waste disposer. Before resetting the overload button, you MUST disconnect the  
power supply.  
Important!  
The motor is permanently lubricated for life. Do not attempt to lubricate your waste disposer.
