INTRODUCTION

Hatco Glo-Ray®Narrow Halogen Strip Heaters keep hot foods
at optimum serving temperatures longer. The bright, halogen
heat lamps keep the focus on the food and the narrow housing
is ideal for installation in tight spaces. Foods do not dry out or
become discolored; even the most delicate dishes hold that
“just-prepared” look.

Glo-Ray Narrow Halogen Strip Heaters 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 Glo-Ray Narrow Halogen Strip Heaters. Hatco
recommends all installation, operating, and safety instructions
appearing in this manual be read prior to installation or
operation of a unit.

Additional information can be found by visiting our web site at
www.hatcocorp.com.

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 is used to address practices not related to personal
injury.

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:

• Unit must be installed by a qualified electrician.
Installation must conform to all local electrical codes.
Installation by unqualified personnel will void the unit
warranty and may lead to electric shock or burn, as well
as damage to unit and/or its surroundings.

• Consult a licensed electrical contractor for proper
electrical installation conforming to local electrical
codes and the National Electrical Code (N.E.C.).

• Turn power OFF at fused disconnect switch/circuit
breaker and allow unit to cool before performing any
maintenance, adjustments, or cleaning.

• 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 the
ambient air temperature is a minimum of 70°F (21°C).

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

• Control box must be mounted in a vertical surface.
Mounting control box in a horizontal surface may result
in the collection of liquids and lead to electric shock.

• Use only Genuine Hatco Replacement Parts when
service is required. Failure to use Genuine Hatco
Replacement Parts 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.

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.

The light fixtures in this unit have glass safety shields
covering the light bulbs to meet National Sanitation
Foundation (NSF) standards. To avoid personal injury
and/or food contamination, always operate the unit with
the glass safety shields properly installed.

Hatco Corporation is not responsible for actual food
product serving temperature. It is the responsibility of the
user to ensure that food product is held and served at a
safe temperature.

This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.

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

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.

Ensure safe and proper operation. Refer to the “Installation
Site Requirements” listed in the INSTALLATION section of
this manual.

FIRE HAZARD:

Form No. GRN4M-1109

• 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 halogen strip heaters. If safe distances are
not maintained, discoloration or combustion could
occur.

a. Do not install halogen strip heaters less than 10″

(254 mm) above combustible surfaces.

b. Do not install halogen strip heaters less than

7″ (178 mm) above non-combustible surfaces.

c. Install all halogen strip heaters with a minimum

distance of 2″ (51 mm) from any 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.

Do not touch halogen heat lamp bulbs with bare hands.
Use gloves, cloth, or paper towel when handling halogen
bulbs. Oil from skin will reduce bulb life and effectiveness.

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

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.

Remote mounted control boxes must be installed outside
strip heater heat zone to prevent premature failure of
components due to excessive heat.

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