Hatco Glo-Ray Heated Display Cases are designed
to hold 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.
Glo-Ray Heated Display Cases keep all foods
at optimum serving temperatures without affecting
quality. These Glo-Ray warmers have prefocused
infrared heat from above and a thermostatically
controlled heated base to extend the holding times
of most foods.
This manual provides the installation, safety
and operating instructions for the Glo-Ray Heated
Display Cases. We recommend all installation, operating
and safety instructions appearing in this manual be read
prior to installation or operation of your Hatco Heated
Display Case. Safety instructions that appear in this
manual after a warning symbol and the words
WARNING or CAUTION printed in bold face are very
important. WARNING means there is the possibility
of serious injury or death to yourself or others.
CAUTION means there is the possibility of minor
or moderate injury. CAUTION without the symbol
signifies the possibility of equipment or property
damage only.
Your Hatco Glo-Ray Heated Display Case is a product
of extensive research and field testing. The materials
used were selected for maximum durability, attractive
appearance and optimum performance. Every unit
is thoroughly inspected and tested prior to shipment.

IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT! Read the following important safety instructions to avoid personal injury or death,
and to avoid damage to the equipment or property.
CAUTIONS
Some exterior surfaces on the unit will get hot.
Use caution when touching these areas
to avoid injury.
For safe and proper operation, the unit must
be located a reasonable distance from
combustible walls and materials. If safe distances
are not maintained, discoloration or combustion
could occur.
To prevent 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 unit must be transported in an upright
position. If laid on its side, all glass surfaces,
pans rails and skirts must be secured with
tape, and water must be removed from
humidified units.
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,
4" (102 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 on GRCD-PDG
and GRCDH-PDG series units do not come
in contact with the heated glass shelf while unit
is in operation.
WARNINGS
To avoid any injury, turn the power switch OFF,
unplug the unit from the power source and allow
to cool before performing any maintenance.
Plug unit into a properly grounded electrical
outlet of the correct voltage, size and plug
configuration. If the plug and receptacle do not
match, contact a qualified electrician to determine
the proper voltage and size and install the proper
electrical outlet.
Only light bulbs which meet or exceed N.S.F
standards, specifically designed for food holding
areas must be used. Breakage of light bulbs not
specifically coated could result in personal injury
and/or food contamination.
Unit is not waterproof. To avoid electrical 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.
To prevent any injury or damage to the unit
do not pull unit by power cord.
To prevent any injury, discontinue use if power
cord is frayed or worn.
To prevent any injury, do not place food directly
on glass or stainless steel surfaces. Food product
must be wrapped or boxed.
To avoid any injury, on GRCD-PDG
and GRCDH-PDG series units do not allow
liquids to spill onto the heated glass shelf.
To avoid any injury, on GRCD-PDG
and GRCDH-PDG series units do not clean
heated glass shelf when unit is energized or hot.

or the front of a curved glass unit, damage to unit
could occur.
To avoid damage to glass do not remove rubber
shipping tabs or tape from glass until legs have
been installed.
Use only non-abrasive cleaners. Abrasive cleaners
could scratch the finish of your Glo-Ray Heated
Display Case, marring its appearance and making
it susceptible to dirt accumulation.
Do not allow the glass shelf to overheat
on GRCD-PDG and GRCDH-PDG series units.
Overheating may cause the food containers
to melt or soften.
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.
