DO'S AND DON'TS

DO …

• First turn on a moderate to strong ﬂow of cold water

and then turn on the disposer. Continue running cold

water for a few seconds after grinding is completed

to ﬂush the drain line.

• Grind hard materials such as small bones, fruit pits,

and ice. A scouring action is created by the particles

inside the grind chamber.

• Grind peelings from citrus fruits to freshen up

drain smells.

Important – The model LC-50 is designed speciﬁcally for light commercial use. Examples of these applications

include: grocery/convenience store delis, fast food restaurants, ofﬁce/church kitchens, and bed and breakfast inns.

Use of this disposer in applications other than those named above may void your warranty.

• Use a disposer cleaner, degreaser, or deodorizer as

necessary to relieve objectionable odors caused by

grease build-up.

OPERATING THE DISPOSER

1. Remove stopper from sink opening and run strong flow of cold water.

2. Turn on wall switch to start disposer.

3. Slowly insert food waste into disposer and position stopper to minimize possible ejection of material while

grinding. After grinding is complete, turn disposer off and run water for a few seconds to flush drain line.

DON'T …

• Don't pour grease or fat down your disposer or any

drain. It can build up in pipes and cause drain

blockages. Put grease in a jar or can and dispose in

the trash.

• Don't use hot water when grinding food waste. It

is OK to drain hot water into the disposer between

grinding periods.

• Don't ﬁll disposer with a lot of vegetable peels all at

once. Instead, turn the water and disposer on ﬁrst

and then feed the peels in gradually.

• Don't grind large amounts of egg shells or ﬁbrous

materials like corn husks, artichokes, etc., to avoid

possible drain blockage.

• Don't turn off disposer until grinding is completed and

only sound of motor and water is heard.
