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.

General

Heated Zone Merchandisers are setup at the factory for energy­saving, automatic operation (Auto Mode
Setpoints” in the SPECIFICATIONS section for factory setpoint
information. Use the following information and procedures to
operate a Heated Zone Merchandiser.

Read all safety messages in the IMPORTANT SAFETY
INFORMATION section before operating this equipment.

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

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.

Theory of Operation

The Heated Zone Merchandiser is designed for efficient and
environmentally-friendly operation by heating specific “zones”
only when product is present. The operation of the Heated Zone
Merchandiser is controlled by a series of optical sensors and
the LCD controller. The sensors are located along the sides of
each hardcoat shelf. Larger units have additional sensors
located in zone dividers that separate each shelf into multiple
overhead heat zones.

For all sizes of units, each hardcoat shelf is equipped with
separate front and rear heating elements. These two elements
operate independently in Auto Mode

The number of overhead ribbon heating elements is determined
by the size of the unit. The overhead elements above each
hardcoat shelf are considered individual heat zones. This means
that the number of zones on each shelf is either two, four, or
six—depending on the size of the unit. Each overhead element
operates independently in Auto Mode

NOTE: Each shelf on a Heated Zone Merchandiser can be set

Auto Mode Operation
At startup in Auto Mode operation, all shelf heating elements

and overhead heating elements in an empty Heated Zone
Merchandiser will be in Stand-By. The front and rear shelf
elements will heat at their Stand-By power percentage to the
setpoint temperature. All overhead elements remain off. When
product is placed on a shelf, the optical sensors signal the LCD
controller, and the controller activates the appropriate shelf
elements and overhead elements. Each of the shelf elements
affected by the placement of product will heat at full wattage to
the setpoint temperature. Each of the overhead elements
affected by the placement of product will heat at its setpoint
power percentage. All affected elements will remain activated
until all product is removed from the “zone.” Anytime a zone is
emptied of product, the zone will return to Stand-By.

On Mode Operation
At startup in On Mode operation, all shelf heating elements will

heat at full wattage to the setpoint temperature, and all
overhead heating elements will heat at their setpoint power
percentage. All shelf elements will remain at full wattage and
all overhead elements will remain at their setpoint power
percentage the entire time the unit is on.
