II. Operating Instructions WARNING, continued A. Important Notes About Usage DANGER Risk of Fire or Explosion Flammable Refrigerant Used • Do not use mechanical devices to defrost. • Do not puncture refrigerant tubing. Risk of fire or explosion due to puncture of refrigerant tubing; follow handling instructions carefully. • Do not place any potential ignition sources in or near the appliance.
WARNING, continued • The appliance is designed only for temporary storage of food. Employ sanitary methods. Use for any other purposes (for example, storage of chemicals or medical supplies such as vaccine and serum) could cause deterioration of stored items. • Do not block air inlets or outlets, otherwise cooling performance may be reduced. • Do not tightly pack the cabinet. Allow some space between items to ensure good air flow. Also allow space between items and interior surfaces.
B. Startup WARNING • All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. • To reduce the risk of electric shock, do not touch the plug with damp hands. IMPORTANT At startup, there is a slight delay before the compressor starts. 1) Plug the appliance into the electrical outlet.
2. Adjusting the Temperature Setpoint The temperature setpoint is the value for the average cabinet temperature. The temperature differential for the compressor to turn on and off is ±3°F (±1.7°C) of the temperature setpoint. For example, for a refrigerator temperature setpoint of 36°F (2°C), the compressor comes on at 39°F (3.7°C), and the compressor goes off at 33°F (0.3°C).
D. Control Module Buttons and Icons Control module icons inform you of energized components and if the appliance is in alarm. Control Module Icons Icon Meaning Compressor Compressor running. Defrost Appliance is in defrost cycle. See "II.E. Defrost" for details. Evaporator Fan Motor Evaporator fan motor is running. Evaporator fan motor de-energizes when door is open (except DT1A). Alarm Appliance is in alarm. See "II.G. Alarm Safeties" for details.
