ELECTRICAL LOCKOUT/TAGOUT PROCEDURE
1. In electrical box, place appliance circuit breaker
into OFF position.
WARNING
Before performing any service that involves
electrical connection or disconnection
and/or exposure to electrical components,
always follow the Electrical LOCKOUT/
TAGOUT Procedure. Disconnect all circuits.
Failure to comply can cause property
damage, injury or death.
2. Place a lock or other device on electrical box
cover to prevent someone from placing circuit
breaker ON.
3. Place a tag on electrical box cover to indicate
that appliance has been disconnected for
service and power should not be restored until

The Electrical LOCKOUT/TAGOUT Procedure is
used to protect personnel working on an electrical
appliance. Before performing any maintenance
or service that requires exposure to electrical
components, follow these steps:
4. Disconnect appliance power cord from
electrical outlet.
5. Place a tag on the cord to indicate that unit
has been disconnected for service and power
should not be restored until tag is removed by

Stainless Steel Care
Cleaning
Stainless steel contains 70-80% iron, which will
rust if not properly maintained. It also contains 1230% chromium, which forms an invisible passive,
protective film that shields against corrosion. If the
film remains intact, the stainless steel will remain
intact. However, if the film is damaged, the stainless
steel can break down and rust.To prevent stainless
steel breakdown, follow these steps:
CAUTION
Never use any metal tools. Scrapers, files, wire
brushes or scouring pads (except for stainless
steel scouring pads) will mar the surface.
CAUTION
Never use steel wool, which will leave behind
particles that rust.
CAUTION
Never use acid-based or chloride-containing
cleaning solutions, which will break down the
protective film.
CAUTION
Never rub in a circular motion.
CAUTION
For routine cleaning, use warm water, mild soap or
detergent and a sponge or soft cloth. For heavyduty cleaning, use warm water, a degreaser and a
plastic, stainless steel or Scotch-Brite pad. Always
rinse thoroughly. Always rub gently in the direction
of the steel grain.
Preserving & Restoring
Special stainless steel polishing cleaners can
preserve and restore the protective film.
Preserve the life of stainless steel with a regular
application of a high quality stainless steel polishing
cleaner as a final step to daily cleaning.
If signs of breakdown appear, restore the stainless
steel surface. First, thoroughly clean, rinse and
dry the surface. Then, on a daily basis, apply a
high-quality stainless steel polish according to
manufacturer’s instructions.
Heat Tint
Darkened areas, called heat tint, may appear
on stainless steel exposed to excessive heat,
which causes the protective film to thicken. It is
unsightly but is not a sign of permanent damage.
To remove heat tint, follow the routine cleaning
procedure. Stubborn heat tint will require heavyduty cleaning.
To reduce heat tint, limit the exposure of equipment
to excessive heat.
Never leave any food products or salt on the
surface. Many foods are acidic. Salt contains
chloride.
