IMPORTANT Indicates important information about the use and care of the appliance.
WARNING, continued • Do not use an appliance with a damaged power cord. The power cord should not be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result in electric shock or fire. To unplug the appliance, be sure to pull the plug, not the cord, and do not jerk the cord. • The GREEN ground wire in the factory-installed power cord is connected to the appliance. If it becomes necessary to remove or replace the power cord, be sure to connect the power cord's ground wire.
WARNING, continued • Do not put warm or hot foods in the cabinet. Let them cool first, or they will raise the cabinet temperature and could deteriorate other foods in the cabinet or overload the appliance. • All foods should be wrapped in plastic film or stored in sealed containers. Otherwise foods may dry up, pass their smells onto other foods, cause frost to develop, result in poor appliance performance, or increase the likelihood of cross‑contamination.

II. Operating Instructions A. Important Notes About Usage WARNING • Only qualified service technicians should install and service the appliance. • Failure to install, operate, and maintain the appliance in accordance with this manual 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. • Do not splash, pour, or spray water directly onto or into the appliance.
WARNING, continued • Do not put warm or hot foods in the cabinet. Let them cool first, or they will raise the cabinet temperature and could deteriorate other foods in the cabinet or overload the appliance. • All foods should be wrapped in plastic film or stored in sealed containers. Otherwise foods may dry up, pass their smells onto other foods, cause frost to develop, result in poor appliance performance, or increase the likelihood of cross‑contamination.
B. Startup WARNING All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. 1) Plug the appliance into the electrical outlet. WARNING! To reduce the risk of electric shock, do not touch the plug with damp hands. At startup, there is a slight delay before the compressor starts. 2) Allow the appliance to cool down prior to loading it with food products.
D. Defrost 1. Undercounter and Worktop Refrigerators Off-Cycle Defrost: Undercounter and worktop refrigerators defrost naturally between run cycles. 2. Prep Table Refrigerators and Undercounter and Worktop Freezers Prep tables and freezers use a heated, time-initiated, temperature-terminated defrost. • Prep tables and freezers have a defrost interval of 6 hours. The defrost timer starts when power is supplied to the appliance. The minimum defrost time is 5 min. The maximum defrost time is 25 min.
E. Food Storage WARNING • 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.
F. Safety Devices 1. Compressor External or Internal Protector If combined temperature/amperage value is above the limit specified by the compressor manufacturer, the compressor protector operates independently to turn off the compressor. The compressor protector de-energizes the compressor until the temperature/amperage value returns to an acceptable level. 2. Short-Cycle Protection There is a 2-minute minimum off-time and on-time for the compressor.
III. Cleaning and Maintenance Instructions A. Cleaning WARNING • Unplug the appliance before cleaning to prevent electric shock by unexpected entrance of water into the appliance or injury by moving parts.
