INTRODUCTION Hatco Intelligent Heated Display Cabinets are designed to hold prepared foods for prolonged periods of time while maintaining that “just-made” quality. Intelligent Heated Display Cabinets provide the best environment for food products by regulating the air temperature while at the same time balancing the humidity level. The use of controlled, moisturized heat maintains serving temperature and food texture longer than conventional dry holding equipment. The air flow pattern is designed to maintain consistent cabinet temperature without drying out foods. The precise combination of heat and humidity creates a “blanket” effect around the food. The air flow rate enables the cabinet to recover temperature rapidly after opening and closing a door. Hatco Intelligent Heated Display Cabinets 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 Intelligent Heated Display Cabinets. Hatco recommends all installation, operating, and safety instructions appearing in this manual be read prior to installation or operation of a unit. Safety information that appears in this manual is identified by the following signal word panels: WARNING WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury. CAUTION CAUTION indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
