Waste Disposer Units – how do they work?
The waste disposers mechanism grinds and has no blades or sharp knives.
Impellers mounted on a spinning plate use centrifugal force to continuously force food waste against a stationary grinding ring.
The grind ring then breaks down the food waste into very fine particles – liquefying them.
Once they are ground down the running water flushes the particles through the grind ring into the wastewater pipe.
Important: With all machinery please be aware that only food waste should be placed into the chamber.
How to use your waste disposal unit
With your waste disposal unit installed, it only takes minimal effort to use it to dispose of unwanted materials. As with any machinery, however, it’s important to understand how to use a waste disposal unit and its inherent limitations.
First, remove the sink stopper or plug and turn on a slow flow of water. Cold water is best, since it keeps waste and fats in a solid form and allows the unit to dispose of them in a quick and easy fashion.
Turn the waste disposal unit’s switch to the ‘On’ position. At this point, the unit’s motor will power up to full speed, and is ready for use. Be aware that the unit’s anti-jam swivel impellers will make a clicking sound when the unit is turned on – this is just the sound of them swinging into place, and is no cause for alarm.
Once the machine is on, scrape any food waste into the plug hole. Matter such as leftover food, peelings, seeds, small bones and coffee grounds will be handled with no issues. Items such as large bones and fibrous waste are no problem for the unit, but they will be dealt with much more quickly if they are first broken down into smaller pieces. If the unit is dealing with something which is particularly hard to break down, it may audibly decrease in speed. This is necessary for the unit to increase the power, or torque, of its grinding process, and just means that everything is operating as it should.
The unit cannot dispose of items made of plastic, tin, glass, china, leather or rubber, and should not be used to dispose of aluminium foil, string or shells. Feeding such items into the unit may damage it, or lessen its ability to properly dispose of other materials. It is suggested that you leave the stopper or plug in the sink at all times when the disposal is not being used. This will lessen the chances of utensils and foreign objects accidentally falling into the unit.
Once the unit has stopped audibly shredding and/or grinding any foodstuffs, allow it to run for 15 seconds with a continuing supply of cold water. This is to allow the unit to clean itself of any remaining matter or particles left over from the main disposal process. After 15 seconds, all waste should have been thoroughly flushed through both trap and drain, and the unit will be clean and ready to use again whenever it is next needed.
We do recommend buying a Mr Scrappy Waste Disposer Tool to push the waste food in to the machine as it can be left in situ and acts as a plug.
