INTRODUCTION

Hatco Glo-Ray®Infrared 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 from being over­cooked in the middle and cooling off around the edges by
concentrating higher temperatures to the outer edges of holding
surfaces where heat loss is the greatest. Utilizing specially
designed reflectors to direct the heat from the element, Glo­Ray Strip Heaters safely maintain peak serving temperatures
longer without cooking the food beyond the point of excellence.

Glo-Ray Infrared Strip Heaters are available from the factory
with or without shatter-resistant incandescent lights to illuminate
the warming area. These bulbs have a special coating that
guards against injury and food contamination in the event of
breakage.

Glo-Ray Infrared Strip Heaters are a product 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 Glo-Ray Infrared 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 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.

NOTICE

NOTICE is used to address practices not related to
personal injury.

WARNING

IMPORTANT SAFETY INFORMATION

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:

• Units supplied without an electrical plug require a hardwired
connection to on-site electrical system. Connection must be
properly grounded and of correct voltage, size, and
configuration for electrical specifications of unit. Contact a
qualified electrician to determine and perform proper electrical
connection.

• 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/turn off power at
circuit breaker, and allow unit to cool before performing any
cleaning, adjustments, 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.

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

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

• 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.

• 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 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, GRL, and GRAL Series) less than 10″ (254 mm) above
combustible surfaces.

b. Do not install high wattage strip heaters (GRH, GRHL,

GRAH, GRNH, GRAHL Series) less than 13-1/2″ (343 mm)

above combustible surfaces.
c. Do not install dual strip heaters above combustible surfaces.
e. Install all single strip heaters with a minimum distance of 3″

(76 mm) from a combustible wall or adjacent surface.

EXPLOSION HAZARD: 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.

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.

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

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.

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.

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 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.

NOTICE

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.

Units are voltage-specific. Refer to specification label for electrical
requirements before beginning installation.

Do not add a decorative soffit to hide a pass-through mounted strip
heater. Excessive heat can cause unit failure.

To prevent premature failure of components due to excessive
heat, remote mounted control switches must be installed outside
the strip heater heat zone.

Damage to any countertop material caused by heat generated
from Hatco equipment is not covered under the Hatco warranty.
Contact the manufacturer of the countertop material for
application information.

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

IMPORTANT—DO NOT use paper towel or glass cleaner to clean
plastic surfaces. Paper towel and glass cleaner may scratch the
material. Wipe off plastic surfaces using a soft, clean, water­dampened cloth.

Do not locate unit in area with excessive air movement around
unit. Avoid areas that may be subject to active air movements or
currents (i.e., near exhaust fans/hoods, air conditioning ducts, and
exterior doors).
