INTRODUCTION

Hatco Glo-Ray®Max Watt Strip Heaters ensure maximum food holding and minimize the risk of foodborne 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 over-cooked 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, Glo-Ray 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.

Form No. GRAMM-0508

IMPORTANT SAFETY INFORMATION

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:

• Do not install Glo-Ray Max Watt strip heaters above or around combustible surfaces. Discoloration or combustion could occur. Glo-Ray Max Watt strip heaters must be installed in non-combustible surroundings only.

• 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.

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.

Light-equipped strip heaters that require a circuit breaker 20 amps or larger must be installed with a remote control enclosure containing a fuse rated at 20 amps or less for the light circuit.

To ensure safe and proper operation, refer to the “Minimum 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.

MODEL DESIGNATION

Figure 1. Model Designation

Form No. GRAMM-0508

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 and switch locations. Optional infinite control switches, electronic infinite control switches, remote control enclosures, incandescent lighting, and halogen lighting are available.
