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.

operation locate the unit indoors

unit is in operation.

All electrical connections must be in
accordance with local electrical codes and
any other applicable codes. Connections

electrician.

WARNINGS

To avoid any injury, turn the power switch
OFF, and allow to cool completely before

spill onto the Heated Glass Overshelf.

Some exterior surfaces on the unit will get

to avoid injury.

To avoid any injury, do not clean Heated
Glass Overshelf when unit is energized or
hot.

shock or personal injury DO NOT submerge
in water. Do not operate if it has been
submerged in water.

To avoid electrical shock or personal injury,
do not steam clean or use excessive water on
the unit.

distances are not maintained, discoloration or
combustion could occur.

For safe and proper operation do not place
food product directly onto glass surface.
Food product must be wrapped or boxed.

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

The fluorescent light fixtures used have
plastic safety shields covering the
fluorescent bulbs to meet N.S.F. standards.
To avoid personal injury and/or food
contamination always operate the unit with
the plastic safety shield properly installed.

After installing a fluorescent light bulb make

IMPORTANT SAFETY INFORMATION

NOTICES

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.

Use of excessive force when tightening
mounting screws may damage unit or
countertop.

Do not use food pans, ceramic dishes, or
abrasive materials on Heated Glass
Overshelves. 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 overshelves be
used for food products contained in
disposable paper or plastic containers or
wrapping.

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

Damage to countertop material such as
Corian

®

and similar products caused by heat
generated from Hatco equipment is not
covered under the Hatco warranty.
Recommended for use over metallic
counters. For other surfaces, verify that the
material is suitable for temperature up to
180°F (82°C).

The Remote Mounted Control Box must be
installed outside of the heat zone. Locating
the control box inside the heat zone will
cause the switches to overheat, malfunction,
and fail. See Figure 6 for minimum mounting
distances.
