INTRODUCTION

Hatco Heated Zone Merchandisers with Spot On®technology
are perfect for holding hot packaged food in convenience
stores, on a buffet line, or at temporary serving areas. Instant­on, individually-zoned overhead ribbon elements are combined
with heated shelves that have separate front and rear heating
elements to significantly reduce energy consumption. Hot
wrapped products are kept at optimum serving temperatures
without affecting quality. These units feature an LCD controller,
LED lighting on each shelf, and come with a cord and plug set.

Hatco Heated Zone Merchandisers are products of extensive
research and field testing. The materials used were selected
for maximum durability, attractive appearance, and optimum
performance. Every unit is inspected and tested thoroughly prior
to shipment.

This manual provides the installation, safety, and operating
instructions for Heated Zone Merchandisers. Hatco
recommends all installation, operating, and safety instructions
appearing in this manual be read prior to installation or
operation of the warmer.

Safety information that appears in this manual is identified by
the following signal word panels:

WARNING indicates a hazardous situation which, if not
avoided, could result in death or serious injury.

CAUTION indicates a hazardous situation which, if not
avoided, could result in minor or moderate injury.

WARNING

WARNING

Read the following important safety information before using this equipment to avoid

serious injury or death and to avoid damage to equipment or property

.

ELECTRIC SHOCK HAZARD:

• Plug unit into a properly grounded electrical receptacle
of the correct voltage, size, and plug configuration. If
plug and receptacle do not match, contact a qualified
electrician to determine and install proper voltage and
size electrical receptacle.

• Turn OFF power switch, unplug power cord, and allow
unit to cool before performing any cleaning, setup, or
maintenance.

• DO NOT submerge or saturate with water. Unit is not
waterproof. Do not operate if unit has been submerged
or saturated with water.

• Unit is not weatherproof. Locate unit indoors where
ambient air temperature is a minimum of 70°F (21°C).

• Do not steam clean or use excessive water on unit.

• This unit is not “jet-proof” construction. Do not use jet­clean spray to clean this unit.

• Do not clean unit when it is energized or hot.

• Do not pull unit by power cord.

• Discontinue use if power cord is frayed or worn.

• Do not attempt to repair or replace a damaged power
cord. Cord must be replaced by Hatco, an Authorized
Hatco Service Agent, or a person with similar
qualifications.

• This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.

• Use only Genuine Hatco Replacement Parts when
service is required. Failure to use Genuine Hatco
Replacement Parts will void all warranties and may
subject operators of the equipment to hazardous
electrical voltage, resulting in electrical shock or burn.
Genuine Hatco Replacement Parts are specified to
operate safely in the environments in which they are
used. Some aftermarket or generic replacement parts
do not have the characteristics that will allow them to
operate safely in Hatco equipment.

FIRE HAZARD: Install unit with a minimum of 3″ (76 mm) of
space from rear of unit to a back wall. If safe distances are
not maintained, discoloration or combustion could occur.

Make sure food product has been heated to the proper
food-safe temperature before placing in unit. Failure to
heat food product properly may result in serious health
risks. This unit is for holding pre-heated food product only.

Do not place food product directly onto hardcoat surface.
Food product must be wrapped, boxed, or on a food pan.

Make sure all operators have been instructed on the safe
and proper use of the unit.

This unit is not intended for use by children or persons
with reduced physical, sensory, or mental capabilities.
Ensure proper supervision of children and keep them away
from the unit.

This unit has no “user-serviceable” parts. If service is
required on this unit, contact an Authorized Hatco Service
Agent or contact the Hatco Service Department at
800-558-0607 or 414-671-6350; fax [phone]; or
International fax [phone].

BURN HAZARD: Some exterior surfaces on unit will get
hot. Use caution when touching these areas.

Locate unit at proper counter height in an area that is
convenient for use. Location should be level to prevent
unit or its contents from falling accidentally and strong
enough to support the weight of the unit and contents.

Do not move or relocate unit for cleaning. Unit is bulky and
heavy.

Do not lay unit on front or back side. Damage to unit could
occur.

Use non-abrasive cleaners and cloths only. Abrasive
cleaners and cloths could scratch finish of unit, marring
its appearance and making it susceptible to soil
accumulation.

IMPORTANT—DO NOT use paper towel or glass cleaner to
clean plastic surfaces such as sneeze guards and
flip-up doors. Paper towel and glass cleaner may scratch
the material. Wipe off plastic surfaces using a soft, clean,
water-dampened cloth.

Do not slide pans across hardcoat surface, use rough­bottomed pans, or drop anything on hardcoat surface.
Scratching may occur. Damage to hardcoat surface caused
by misuse is not covered under warranty.

Clean unit daily to avoid malfunctions and maintain
sanitary operation.
