OPERATING INSTRUCTIONS
The Anti-Jam Swivel Impellers make a clicking sound as they initially swing into place. This
indicates normal operation.
»Remove sink stopper. Turn on a medium flow of cold water.
»Turn switch to ON position; your motor is turning at full speed and ready to use.
»Scrape in food waste. Down the drain go table scraps, peelings, rinds, seeds, pits, small bones
and coffee grounds. To speed up food waste disposal, cut or break up large bones, rinds
and cobs. Large bones and fibrous waste require considerable grinding time and are more
easily thrown away with other trash. Do not be alarmed that the disposer slows down while
grinding. The disposer is actually increasing torque (grinding power) and is operating under
normal conditions.
»Before turning disposer off, let water and disposer run for approximately 15 seconds after
shredding or grinding stops. This assures that all waste is thoroughly flushed through trap and
drain.
»It is not recommended to use hot water while running disposer. Cold water will keep waste
and fats solid so disposer can flush away particles.
TIPS FOR SUCCESSFUL OPERATION:
»Be sure disposer is empty before using your dishwasher so it may drain properly.
»You may want to leave the stopper in the drain when not in use to prevent utensils and
foreign objects from falling into the disposer.
»Your disposer is ruggedly built to give you many years of trouble free service. It will handle all
normal food wastes, but it will NOT grind or dispose of such items as plastic, tin cans, bottle
caps, glass, china, leather, cloth, rubber, string, clams and oyster shells, aluminium foil
or feathers.

Instruction manual WDU12514 Please keep this instruction manual for future reference
CLEANING AND MAINTENANCE
DO NOT ATTEMPT TO LUBRICATE YOUR DISPOSER
The motor is permanently lubricated. The disposer is self cleaning and scours its internal parts with
each use.
WARNING:
Never put bleach or chemical drain cleaners into the disposer, as they cause serious corrosion of
metal parts. If used, resulting damage can be easily detected and all warranties are void. Mineral
deposits from your water can form on the stainless steel turntable, giving the appearance of rust.
Do not be alarmed, the stainless steel turntables used will not corrode and can be cleaned
accordingly.
