INTRODUCTION

Hatco Glo-Ray® Heated Display Cases are designed to hold prepared foods for prolonged periods of time while maintaining that “just made” quality. Hatco Display Cases provide the best environment for food products by regulating the air temperature. Display models equipped with humidity control also balance the humidity level. The use of controlled heat maintains serving temperature and texture longer than conventional holding equipment.
Hatco Glo-Ray Heated Display Cases 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 Hatco Glo-Ray Heated Display Cases. Hatco recommends all installation, operating, and safety instructions appearing in this manual be read prior to installation or operation of a unit.

• Turn OFF the power switch, unplug the power cord, and allow the unit to cool before performing any cleaning, adjustments, or maintenance.
• unit is not weatherproof. Locate the unit indoors where the ambient air temperature is a minimum of 70°F (21°C).
• DO NOT submerge or saturate with water. unit is not waterproof. Do not operate if the unit has been submerged or saturated with water.
• 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 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: Locate the unit a minimum of 1″ (25 mm) from combustible walls and materials. If safe distances are not maintained, discoloration or combustion could occur.
EXPLOSION HAZARD: Do not store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance.
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.
Hatco Corporation is not responsible for the 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.
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.
WARNING
Do not place food products directly onto shelves. 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.
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.
• Hot water in the unit may cause scalding injury. Allow the unit to cool before draining or cleaning.

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 the unit cannot be sealed at the point of use, 4″ (102 mm) legs are included to allow for proper cleaning access below the unit.
NOTICE
Do not lay the unit on the side with the control panel or in front of a curved glass unit. 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.
The use of distilled water in the water reservoir of humidified units is recommended to preserve the life of electrical and mechanical components. If non-distilled water is used, the reservoir will require periodic cleaning and deliming (refer to the MAINTENANCE section for the cleaning procedure). unit failure due to lime or mineral deposits is not covered under warranty.
Clean unit daily to avoid malfunctions and maintain sanitary operation.
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).
