prepared foods for prolonged periods of time while maintaining
that “just made” quality. Hatco Display Cases provide the best
environment for food products by regulating the air temperature.
Display models equipped with humidity control also balance the
humidity level. The use of controlled heat maintains serving
temperature and texture longer than conventional holding
equipment.
Hatco Glo-Ray Heated Display Cases 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 Hatco Glo-Ray Heated Display Cases. Hatco
recommends all installation, operating, and safety instructions
appearing in this manual be read prior to installation or
operation of a unit.
Heated Display Cases are designed to hold
Safety information that appears in this manual is identified by

• Do not attempt to repair or replace a damaged power
cord. The 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.

• Some exterior surfaces on unit will get hot. Use caution
when touching these areas.
• Hot water in unit may cause scalding injury. Allow unit
to cool before draining or cleaning.
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 weight of unit and contents.
The National Sanitation Foundation (NSF) requires that

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.
Use of distilled water in the water reservoir of humidified
units is recommended to preserve the life of electrical and
mechanical components. If non-distilled water is used, the
reservoir will require periodic cleaning and deliming (refer
to the MAINTENANCE section for cleaning procedure). Unit
failure due to lime or mineral deposits is not covered under
warranty.
Clean unit daily to avoid malfunctions and maintain
sanitary operation.

WARNING
CAUTION
NOTICE
General
Glo-Ray®Heated Display Cases are shipped with most
components pre-assembled. Care should be taken when
unpacking shipping carton to avoid damage to unit and
components enclosed.
ELECTRIC SHOCK HAZARD: Unit is not weatherproof.
Locate unit indoors where ambient air temperature is a
minimum of 70°F (21°C).
FIRE HAZARD: Locate unit a minimum of 1″ (25 mm) from
combustible walls and materials. If safe distances are not
maintained, discoloration or combustion could occur.
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 weight of unit and contents.
The National Sanitation Foundation (NSF) requires that
units over 36″ (914 mm) in width or weighing more than 80
lbs. (36 kg) either be sealed to or raised above the
installation surface. If unit cannot be sealed at the point of
use, 4″ (102 mm) legs are included to allow for proper
cleaning access below unit.
Transport unit in upright position only. Before moving or
tipping unit, secure all glass surfaces, doors, pan rails,
and/or skirts with tape, and drain water from humidified
units. Failure to do so may result in damage and injury.
Assembling GRCD Models
Position the unit upright on the counter near the location it will
be used. Installation of the following items is required before
operating the unit.
1. Remove plastic bag containing the 4″ (102 mm) adjustable
legs from inside the unit.
2. Remove the pan rail (GRCD units); or pan skirts and water
reservoir (GRCDH units).
3. Remove the front curved glass by rotating it partially forward
and lifting straight up and off. Discard the rubber packing
strips.
4. Remove rear doors on 2-pan and 3-pan models by grasping
the door edges then lifting up and out of the bottom channel.
Discard the protective cardboard from top of each door.
NOTE: Do not remove the plastic glides from the top of the door
glass before completing assembly.
NOTE: Models GRCD-1P and GRCDH-1P have a single,
hinged door that does not need to be removed.
Do not lay unit on the side with control panel or on front of
a curved glass unit. Damage to unit could occur.
5. Carefully lay the unit on its side. Two people are required
for this step.
6. Install the 4″ (102 mm) legs to the bottom of the unit. Hand
tighten the legs until snug. Do not over-tighten.
Do not remove rubber shipping tabs or tape from glass
surfaces until legs have been installed. Damage to glass
could occur.
NOTE: Unit must be transported in the upright position.
1. Remove the unit from the carton. Two people are required
for this step.
NOTE: To prevent delay in obtaining warranty coverage,
complete online warranty registration. See the
IMPORTANT OWNER INFORMATION section for
details.
2. Perform either “Assembling GRCD Models” or “Assembling
GRHD Models” in this section, depending on the unit.
3. Place the unit in the desired location.
• Locate the unit in an area where the ambient air
temperature is constant and a minimum of 70° F (21° C).
Avoid areas that may be subject to active air movements
or currents (i.e., near exhaust fans/hoods and air
conditioning ducts).
• Make sure the unit is at the proper counter height in an
area convenient for use.
• Make sure the countertop is level and strong enough to
support the weight of the unit and food product.
• Make sure all the feet on the bottom of the unit are
positioned securely on the countertop.
Installing the 4″ (102 mm) Legs—GRCD Models
NOTE: The feet on the 4″ legs are adjustable for leveling the
unit. Use a 9/16″ (14 mm) open-end wrench to make
leveling adjustments once the unit is placed in its final
position.
7. Return the unit to the upright position. Two people are
required for this step.

the correct voltage, size and plug configuration. See the
SPECIFICATIONS section for details.
GRCD and GRHD (Non-Humidified) Models
1. Move the Power ON/OFF (I/O) switch on the base to the
ON (I) position.
2. Turn the BASE HEAT CONTROL to the desired temperature
setting.
3. Turn the TOP HEAT CONTROL and the CENTER HEAT
CONTROL (dual units only) to the desired temperature
setting.
NOTE: On dual shelf models, the TOP HEAT and CENTER
HEAT indicator lights will illuminate when controls are
in the ON position.
BURN HAZARD: Some exterior surfaces on unit will get
hot. Use caution when touching these areas.
