INTRODUCTION
Hatco Glo-Ray®Strip Heaters ensure maximum food
holding and minimize the risk of food-borne illness.
Optimum safety and quality is the result of food held
at the proper serving temperatures, using Glo-Ray’s
pre-focused heat patterns. The pre-focused heat
pattern prevents foods frombeing over-cooked in the
middle and cooling off around the edges by
concentratinghighertemperaturesto the outer edges
of holding surfaces where heat loss is the greatest.
Utilizing specially designed reflectors to direct the
heat from the element, Glo-Ray Strip Heaters safely
maintain peak serving temperatures longer without
cooking the food beyond the point of excellence.
Glo-Ray Strip Heaters are available from the factory
withor without shatter-resistantincandescentlightsto
illuminate the warming area. These bulbs have a
special coating that guards against injury and food
contamination in the event of breakage.
Glo-Ray Strip Heaters are a product of extensive
research and field testing. The materials used were
selected for maximum durability, attractive
appearance,and optimumperformance.Every unit is
inspected and tested thoroughly prior to shipment.
Additional information can be found by visiting our
web site at www.hatcocorp.com.
This manual provides the installation, safety, and
operating instructions for Glo-Ray Strip Heaters.
Hatco recommends all installation, operating, and
safety instructions appearing in this manual be read
prior to installation or operation of the Strip Heaters.
Safety information that appears in this manual is
identified by the following signal word panels:
WARNING indicates a hazardous situation

IMPORTANT SAFETY INFORMATION
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:
• For hard-wired units, all electrical
connections must be in accordance with
local electrical codes and any other
applicable codes. Connections should be
made by a qualified, licensed electrician.
• Units equipped with a cord and plug supplied
by Hatco must be plugged 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 and install
the proper voltage and size electrical outlet.
• Unplug the power cord or turn the power OFF
at the fused disconnect switch/circuit
breaker and allow the unit to cool before
performing any maintenance or cleaning.
• Discontinue use if power cord is frayed or
worn.
• 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.
• DO NOT submerge or saturate with water.
Unit is not waterproof. Do not operate if unit
has been submerged or saturated with water.
• This unit is not “jet-proof” construction. Do
not use jet-clean spray to clean this unit.
• 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:
• Locate the unit the correct distance from
combustible walls and materials. If safe
distances are not maintained, discoloration
or combustion could occur. Refer to specific
installation and mounting information in this
manual for proper clearances.
• Make sure to follow the installation
information listed below for specific strip
heaters. If safe distances are not maintained,
discoloration or combustion could occur.
a. Do not install standard wattage strip
heaters (GR, GRA, GRN, GRAL Series)
less than 10″ (254 mm) above combustible
surfaces.
b. Do not install high wattage strip heaters
(GRH, GRAH, GRNH, GRAHL Series) less
than 13-1/2″ (343 mm) above combustible
surfaces.
c. Do not install dual strip heaters (GRA-
XXD, GRAH-XXD, GRAL-XXD, and GRAHLXXD Series) above combustible surfaces.
e. Install all single strip heaters with a
minimum distance of 3″ (76 mm) from a
combustible wall or adjacent surface.
• Do not store or use gasoline or other
flammable vapors or liquids in the vicinity of
this or any other appliance.
Use only light bulbs that meet or exceed
(National Sanitation Foundation (NSF)
standards and are specifically designed for food
holding areas. Breakage of light bulbs not
specially coated could result in personal injury
and/or food contamination.
For installation with chains, make sure the
chains have sufficient strength and are securely
fastened to both the unit and the mounting
location. Poorly installed chains may cause the
unit to loosen and fall. Do not place anything on
top of units installed with chains.

BURN HAZARD: Some exterior surfaces on the
unit will get hot. Use caution when touching
these areas.
Standard and approved manufacturing oils may
smoke up to 30 minutes during initial startup.
This is a temporary condition. Operate unit
without food product until smoke dissipates.
Strip heaters equipped with incandescent lights
that require a circuit breaker larger than 20 amps
for the heat element must have a separate circuit
breaker for the incandescent lights that is 20
amps or less.
To ensure safe and proper operation, refer to the
Clearance Requirements listed in the Installation
section of this manual.
Installation of two or more separate units with
less than 3″ (76 mm) between housings may
result in premature failure of component parts.
Failure to provide proper spacing may result in
heat damage to electrical components.
To prevent unit failure, do not add a decorative
soffit to hide a pass-through mounted strip
heater.
To prevent premature failure of components due
to excessive heat, remote mounted control
boxes must be installed outside the strip heater
heat zone.
Heat damage to countertop material such as
Corian®and similar products (other than
stainless steel) is not covered under the Hatco
warranty. Contact the manufacturer of the base
material for temperature limits and application
information before installing the unit.
Use non-abrasive cleaners only. Abrasive
cleaners could scratch the finish of the unit,
marring its appearance and making it
susceptible to dirt accumulation.

foods at optimum serving temperatures longer.
Foods do not dry out or become discolored; even
the most delicate dishes hold that “just-prepared”
look. The Glo-Ray pre-focused heat pattern directs
heat from a tubular element to bathe the entire
holding surface.
Glo-Ray strip heaters can be ordered in standard or
high wattage configurations, aluminum housings in
lengths of 18″ (457 mm) to 144″ (3658 mm),
stainless steel housings in lengths of 24″ (610 mm)
to 96″ (2438 mm), or narrow design housings in
lengths of 18″ (457 mm) to 72″ (1829 mm).
Glo-Ray dual models allow for side-by-side
mounting of two or more strip heaters to provide a
wider holding area (dual models are constructed
with a required 3″ [76 mm] or 6″ [152 mm] spacer
between heating elements).

NOTE: GRAL & GRAHL Models that have multiple voltages listed, such
as 120/208, 120/240 or 100/200, have multiple circuits. For
example a 120/208 volt unit utilizes 120 volts for light circuit and
208 volts for the heat circuit(s). Consult Electrical Diagram
supplied with the unit for specific information.
CAUTION! Strip heaters equipped with incandescent lights
that require a circuit breaker larger than 20 amps for the
heat element must have a separate circuit breaker for the
incandescent lights that is 20 amps or less.
