IMPORTANT SAFETY INFORMATION

CAUTIONS

Some exterior surfaces on the unit will get
hot. Use caution when touching these areas
to avoid injury.

To avoid any injury or damage locate the unit
at the proper counter height, in an area that is
convenient for use. The location should be
level to prevent the unit or its contents from
accidentally falling, and strong enough to
support the weight of the unit and food
displayed.

The National Sanitation Foundation (NSF)
requires units over 36" (914 mm) in length or
weighing more than 80 lbs. (36 kg) to be either
sealed or raised on the installation surface. If
this unit cannot be sealed at the point of use,
2-1/2" (64 mm) legs are included to allow for
proper cleaning access below unit.

Unit is not weatherproof. For safe and proper
operation locate the unit indoors where the
ambient air temperature is constant and is a
minimum of 70°F (21°C).

To avoid any injury, do not come in contact
with the heated glass shelf while unit is in
operation.

For safe and proper operation, the top side of
the upper most shelf is intended for short
term holding of food for which serving
temperature is not critical.

To allow for proper cleaning and operation
the lower vented side covers must be
removed before installing legs.

CAUTIONS

Use only non-abrasive cleaners. Abrasive
cleaners could scratch the finish marring its
appearance and making it susceptible to dirt
accumulation.

Only soft cleaning cloths, mild soap and
water should be used to clean breath
protector(s). Breath protector(s) are made of
shatterproof polycarbonate and will scratch
or crack if proper care is not taken.

Do not allow the glass shelf to overheat.
Overheating may cause the food containers
to melt or soften.

Do not lay unit on the side with the control
panel or damage to unit could occur.

Do not use food pans, ceramic dishes, or
abrasive materials on heated glass shelves.
Food pans, ceramic dishes, and abrasive
materials may scratch the glass shelf marring
its appearance and making it susceptible to
dirt accumulation. It is recommended that
glass shelves be used for food products
contained in disposable paper or plastic
containers or wrapping.

IMPORTANT! Read the following important safety instructions to avoid personal injury
or death, and to avoid damage to the equipment or property.
