INTRODUCTION
Hatco Glo-Ray® Max Watt 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 Max Watt 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 Max Watt 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.
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 Max Watt 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 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 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.
• Turn OFF power switch, 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 jetclean spray to clean this unit.
• Do not steam clean or use excessive water on 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: Do not install MaxWatt strip heaters above
or around combustible surfaces. Discoloration or
combustion could occur. Max Watt strip heaters must be
installed in non-combustible surroundings only.
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. Failure to heat food product
properly may result in serious health risks. This unit is for
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 800-690-2966; or
International fax 414-671-3976.
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 and will void warranty.
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 enclosures 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.
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).

All Models
Hatco Glo-Ray®Max Watt Strip Heaters keep hot 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 Max Watt strip heaters are constructed with aluminum
housings in lengths of 18″ (457 mm) to 144″ (3658 mm).
Dual models allow for side-by-side mounting of two heating
elements to provide a wider holding area (dual models are
constructed with a standard 3″ [76 mm] or optional 6″ [152 mm]
spacer between heating elements).
All Glo-Ray Max Watt Strip Heaters have several mounting
options. Optional electronic infinite control switches,
incandescent lighting, and halogen lighting are available.

General
Use the information in this section to prepare for and install a
Max Watt Strip Heater. Make sure to locate the specific
information in this section for the type of installation. Strip
heaters are shipped with most components pre-assembled.
Dual units are supplied with a required 3″ (76 mm) or
6″ (152 mm) spacer pre-assembled at the factory.
Optional mounting equipment and remote control enclosures
must be installed on location.
FIRE HAZARD: Do not install MaxWatt strip heaters above
or around combustible surfaces. Discoloration or
combustion could occur. Max Watt strip heaters must be
installed in non-combustible surroundings only.
To ensure safe and proper operation, refer to the “Minimum
Clearance Requirements” listed in the Installation section
of this manual.
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.
To prevent unit failure from excessive heat, do not add a
decorative soffit to hide a pass-through mounted strip
heater.
NOTE: Contact the countertop manufacturer of the base
material for application information and surface
temperature limits before installing the unit.
1. Remove the unit from the shipping carton and remove all
packing materials.
NOTE: To prevent delay in obtaining warranty coverage,
complete online warranty registration. See the
IMPORTANT OWNER INFORMATION section for
details.
2. Remove tape and protective packaging from all surfaces
of the unit.
NOTE: If unit is equipped with optional equipment, see the
OPTIONS AND ACCESSORIES section near the back
of this manual.
3. Install/mount the unit in an appropriate location.

clearance requirements are met for the appropriate
model. Refer to “Recommended Mounting Heights” and
“Minimum Clearance Requirements” in this section.
c. For permanent unit installation, refer to “Installing
Permanent Units” in this section.
b. For chain suspension installation, refer to “Installing
Chain Suspended Units” in this section.
Dual Mounting
When mounting units side-by-side, a space not less than 3″
(76 mm) must be maintained between units. Dual units ordered
from the factory are shipped with a pre-assembled 3″ (76 mm)
or 6″ (152 mm) spacer.
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 and will void warranty.
Under Shelf Mounting
When mounting a unit under a shelf, use adjustable angle
brackets to assure proper spacing. Remote control enclosures
are required to keep switches out of the heat zone and prevent
premature failure.
Pass-Through
If pass-through area is 12″ to 16″ (305 to 406 mm) deep, a
single unit can be used. For a 20″ to 24″ (508 to 610 mm) deep
pass-through area, a dual unit is recommended. Installation of
multiple units must have a minimum spacing of 3″ (76 mm)
between heaters.

Adjustable Angle Bracket Mounting
Mounting a strip heater with adjustable angle brackets
permanently attaches the unit to the underside of a shelf. Units
can be mounted to a flat shelf or a shelf with rolled/flanged
edges. A minimum gap of 1″ [25 mm] is required between the
unit and the bottom of the rolled or flanged edge to prevent heat
damage to the electrical system of the unit.
To ensure safe and proper operation, refer to the Clearance
Requirements listed in the Installation section of this
manual.
If the shelf has a rolled or flanged edge, use the appropriate
screw hole locations on the adjustable angle brackets to mount
the unit 1″ (25 mm) below the lowest edge of the rolled or
flanged shelf. The adjustable angle brackets can provide a 1″
[25 mm], 1-1/2″ [38 mm], or 2″ [51 mm] gap between the unit
and the underside of the shelf.
Do not conceal unit. Unit must be installed below the
lowest edge of a rolled or flanged shelf. Failure to mount
unit properly may result in premature failure of
components and void the product warranty.

Installing Chain Suspended Units
Chain suspension mounting attaches a strip heater to an
overhead surface with the use of “S” hooks. Chain suspended
units are available for single housing models only.
NOTE: Units ordered with the “S” hook option come with two
hanger tabs mounted to each end of the unit, two “S”
hooks, and two 6″ (152 mm) pieces of connecting chain.
Additional chain (P/N 05.03.020.00) can be ordered from
Hatco for the overhead mounting system or another
option can be determined by a qualified installer.
Flanged Shelf Installation
1. Position the unit on a flat surface with the heating element
facing down.
2. Remove the two center screws from the end plate at one
end of the unit. These screws do not need to be replaced.
3. Remove the two upper end plate screws.
4. Align the appropriate holes on the adjustable angle bracket
with the end plate mounting holes on the unit. Secure the
angle bracket with the end plate screws.

using appropriate fasteners (not supplied by Hatco).
NOTE: Two pairs of brackets will be needed for dual units.
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.
To ensure safe and proper operation, refer to the “Minimum
Clearance Requirements” listed in the Installation section
of this manual.
NOTE: The strength of the chain supplied by Hatco is sufficient
to hold the weight of the unit securely only when
mounted properly.
NOTE: Dual units cannot be mounted using the “S” hook and
chain system.
1. Prepare the overhead mounting system for the “S” hooks.
Make sure the system is secure and is set up so the unit
will be suspended at a level, safe, and proper distance from
walls, counter, and food.
2. Loosen, but do not remove the screws securing the hanger
tabs on each end of the unit. Rotate the tabs up, then
tighten the screws securely.
3. Securely attach one of the 6″ (152 mm) connecting chains
between each pair of hanger tabs.
4. Attach an “S” hook to the center of each connecting chain.
5. Carefully lift the unit and attach the “S” hooks on each end
of the unit to the overhead mounting system. Make sure
the unit is level.
