INTRODUCTION

The Hatco Glo-Ray ® Heated Glass Merchandising Warmers, GR3SDH (Horizontal Shelf) and GR3SDS (Slant Shelf) are perfect for holding hot wrapped or boxed foods on a buffet line or customer serving points. A thermostatically controlled, hard-coated heated base and unique patented heated glass shelf hold hot-wrapped or boxed food products and keep them at optimum serving temperatures while maintaining product quality.
These warmers offer an additional heated shelf on the top, ideal for use of short-term holding of food for which serving temperature is not critical. The Glo-Ray Heated Glass Merchandising Warmers are guaranteed against breakage and burnout for one year. These units also feature LED display lights along with a cord and plug set.
Hatco Glo-Ray Heated Glass Merchandising Warmers 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 Heated Glass Merchandising Warmers. Hatco recommends all installation, operating, and safety instructions appearing in this manual be read prior to installation or operation of the unit.

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.
WARNING
ELECTRIC SHOCK HAZARD:

• Plug the unit into a properly grounded electrical receptacle 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 receptacle.
• Turn OFF the power switch, unplug the power cord, and allow the unit to cool before performing any cleaning, setup, or maintenance.
• Units with two power cords must have both power supply cords disconnected before performing any cleaning, adjustments, or maintenance.
• DO NOT submerge or saturate with water. The unit is not waterproof. Do not operate if the unit has been submerged or saturated with water.
• Unit is not weatherproof. Locate the 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 a jet-clean spray to clean this unit.
• Do not clean the unit when it is energized or hot.
• Do not pull the unit by the power cord.
• Discontinue use if the 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.
• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.
• 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: Install the unit with a minimum of 3″ (76 mm) of space from the rear of the unit to a back wall. If safe distances are not maintained, discoloration or combustion could occur.
Make sure food product has been heated to the proper food-safe temperature before placing them in the unit. Failure to heat food products properly may result in serious health risks. This unit is for holding pre-heated food products only.
Do not place food products directly onto the hard coat surface. The food product must be wrapped, boxed, or on a food pan.
Make sure all operators have been instructed on the safe and proper use of the unit.
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.
WARNING
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.
CAUTION
BURN HAZARD: Some exterior surfaces on the unit will get hot. Use caution when touching these areas.
Locate the unit at the proper counter height in an area that is convenient for use. The location should be level to prevent the unit or its contents from falling accidentally and strong enough to support the weight of the unit and contents.
The National Sanitation Foundation (NSF) requires that units over 36″ (914 mm) in width or weighing more than 80 lbs. (36 kg) either be sealed to or raised above the installation surface. If this unit cannot be sealed at the point of use, 2-1/2″ (64 mm) legs are included to allow for proper cleaning access below the unit.
Do not move or relocate the unit for cleaning. The unit is bulky and heavy.
NOTICE
Do not lay the unit on the front or backside. Damage to the unit could occur.
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 towels or glass cleaners to clean plastic surfaces such as sneeze guards and flip-up doors. Paper towels and glass cleaners may scratch the material. Wipe off plastic surfaces using a soft, clean, water- dampened cloth.
Do not use food pans, ceramic dishes, or abrasive materials on a heated glass shelf. Scratching of the glass surface may occur, marring its appearance and making it susceptible to soil accumulation. Damage to glass surface or breakage of glass caused by misuse is not covered under warranty.
Do not slide pans across the hard coat surface, use rough-bottomed pans, or drop anything on hardcoat surface. Scratching may occur. Damage to hardcoat surface caused by misuse is not covered under warranty.
Do not allow the glass shelf to overheat. Overheating may cause the food containers to melt or soften. Do not locate a unit in an area with excessive air movement around the 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).
Clean unit daily to avoid malfunctions and maintain sanitary operation.
