• To reduce the risk of electric shock, do not touch the plug with damp hands.
• Unplug the appliance before servicing.
• The appliance requires an independent power supply of proper capacity. See the nameplate for electrical specifications. Failure to use an independent power supply of proper capacity can result in a tripped breaker, blown fuse, damage to existing wiring, or component failure. This could lead to heat generation or fire.

• THE APPLIANCE MUST BE

GROUNDED. The appliance is equipped with a NEMA 5-15 three-prong grounding plug ☐ to reduce the risk of potential shock hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualified electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not remove the ground prong from the power cord and do not use an adapter plug. Failure to follow these instructions may result in death, electric shock, or fire.

• Do not use an extension cord.
• 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.
• Do not splash, pour, or spray water directly onto or into the appliance. This might cause short circuit, electric shock, corrosion, or failure.
• Do not make any alterations to the appliance. Alterations could result in electric shock, injury, fire, or damage to the appliance.
• The appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

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.

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 have a defrost interval of 6 hours and freezers have a defrost interval of 8 hours. The defrost timer starts when power is supplied to the appliance.
  The minimum defrost time is 5 min.
  The maximum defrost time is 45 min. for prep tables and 1 hour for freezers.

• When the defrost thermistor warms to 46^ (7.7°C) on prep tables and 50^ (10°C) on freezers, defrost terminates.

• On prep tables, the compressor energizes 1-min. after defrost heater de-energizes (drip time) and the evaporator fan motor(s) energize 30-sec. after the compressor energizes. Note that the 30-sec. evaporator fan motor delay time is a maximum; if the defrost thermistor cools to 40^ (4.4°C) before the 30-sec. evaporator fan motor delay timer terminates, the evaporator fan motor(s) will energize.

- On freezers, the compressor energizes 3-min. after defrost heater de-energizes (drip time) and the evaporator fan motor(s) energize 4-min. after the compressor energizes. Note that the 5-min. evaporator fan motor delay time is a maximum; if the defrost thermistor cools to 25^ (-3.8°C) before the 5-min. evaporator fan motor delay timer terminates, the evaporator fan motor(s) will energize.

To manually initiate or terminate a defrost cycle: Turn the cabinet temperature control dial to 7, pause for 3 to 10 sec., then return the cabinet temperature control dial to any position below 7. Defrost initiates or terminates within 5 sec.

Note: When defrost is manually initiated it continues through the normal defrost cycle unless manually terminated.
