User Manual
Defrost System
Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). During compressor
down-time, the evaporator fan continues to circulate air through the evaporator coil. This air
circulation raises the coil temperature above the freezing point, melting any accumulated frost.
Run-off water is drained into the evaporator pan and evaporated.
Operation/Maintenance
NOTE: We strongly recommend that any servicing be performed by an authorized service technician.
Unplug the unit from the elecrical outlet before cleaning or making repairs.
Loading Product
• Do not block the air duct / fan at the top of the unit. Maintain a minimum of 4” of clearance
between products and the fan at all times.
• Ensure all shelves are sitting level and properly secured before loading products.
• Do not store flammable and explosive gas or liquids inside the unit.
Cleaning the Condensor Coil
• For efficient operation, keep the condenser surface free of dust, dirt, and lint.
• We recommend cleaning the condenser coil at least once per month.
• Clean the condenser with a commercial condenser coil cleaner and a soft brush, available from
any kitchen equipment retailer, or vacuuming the consenser with a shop vac or use Co2.
Cleaning the Fan Blades and Motor
• If necessary, clean the fan blades and motor with a soft cloth.
• If it is necessary to wash the fan blades, cover the fan motor to prevent moisture damage.
Cleaning the Interior of Unit
• When cleaning the cabinet interior, use a solvent of warm water and mild soap.
• Do not use steel wool, caustic soap, abrasive cleaners, or bleach that may damage the interior finish.

frame of the door, soak it in warm water and soap for thirty (30) minutes, then dry with soft cloth
and replace.
