INSTALLATION. Unit should not be installed in an area where adverse environmental conditions are present.
ELECTRICAL CHARACTERISTICS. 3 wire grounded tri-directional power cord and plug, corner mounted for safety. See electrical data chart above for amperage and receptacle configuration. See electrical chart for models that require a dedicated circuit.
COLD-TEMP SYSTEM/CONTROLS. A 1/4 HP Hi-torque condensing unit, air-cooled closed system has a three pound receiver charged with environmentally safe ANSI/ ASHRAE Standard 34-1992 Safety Group Classification (A1) 450A refrigerant. A thermal expansion valve (for pressure control) also a filter dryer. Controls shall include an easy to read digital display for cabinet temperature (with recall capability of temperature set point and actual cabinet temperature). Easy to read master ON/OFF button with power indicator light, cooling cycle indicator light, on-demand defrost with a defrost cycle indicator light. Adjustable temperature range from 33°F to 38°F (.5°C to 3.3°C) factory preset temperature is 38°F (3.3°C).
HEATING SYSTEM/CONTROLS. Top mounted, forced air blower system shall include one (1) Hi-Temp, self-lubricated, impedance protected, fan-cooled blower motor to distribute heat equally throughout cabinet interior. Heating element shall be located at top of cabinet to eliminate hot spots and to prevent overheating of lower trays and pans. Wall heat distribution tunnel shall be vented for balanced air circulation. Controls shall be up-front, recessed and shall include a full range thermostat adjustable to actual temperature. Thermostat shall include temperature scale marked in ten degree increments (F/C) from 90° to 190°F (30° to 90°C). An operational range thermometer, power supply light, thermostat cycling light, and 20 amp ON/OFF switch are also included.
TAMPER RESISTANT FEATURES. Cabinet shall have thermostat knob retention strap, and 1/4" thick plexiglass cover over the thermometer. Both shall be attached with tamper-proof fasteners to prevent unauthorized removal.
