lower the number that is selected on the
temperature control knob, the lower the
internal temperature will be.

The LCD will display the selected

The unit will continue heating until the
selected temperature has been reached
and then cycle off and on to maintain the
selected temperature. Meanwhile the LCD
will display the fluctuating temperatures.

MAINTENANCE

Cleaning

Disconnect
electrical power to the
machine and follow Lockout/
Tagout procedures before
cleaning.

The cabinet and its parts
are hot. Allow it to cool before cleaning or
servicing the unit.

Daily

1. Disconnect electrical power and follow

Lockout/Tagout procedures.

2. Allow unit to cool before cleaning.

3. Remove tray slides or plate racks, and

with a soft cloth, wash and rinse in a sink
as you would any utensil.

4. With a mild soap solution, soft cloths and

fresh water, wash, rinse and dry the interior
of the cabinet.

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: Never leave any food
products or salt on the surface. Many
foods are acidic. Salt contains chloride!

For routine cleaning, use warm water, mild
soap or detergent and a sponge or soft cloth.

For heavy-duty 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

5. Place tray slides or plate racks in the

cabinet.

6. To clean and maintain stainless steel

surfaces, see STAINLESS STEEL CARE .

STAINLESS STEEL CARE
Cleaning

Stainless steel contains 70-80% iron, which
will rust if not properly maintained. It also
contains 12-30% 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), which will mar the surface!

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
heavy-duty cleaning.

To reduce heat tint, limit the exposure of
equipment to excessive heat.
