Installation

Please read this manual thoroughly prior to equipment set-up, operation and maintenance. This unit is intended for use in a temperature-controlled environment less than 75°F and 55% relative humidity. Malfunction due to improper conditions is not covered under warranty.

Important!!! Please Read Before Installation

• If the unit has recently been transported on its side, please let the unit stand upright for a minimum of 24 hours before plugging it in.
• Make sure all accessories are installed (shelves, shelf clips, etc...) before plugging in the unit.
• Make sure the unit has reached the desired temperature before loading the unit with products.
• Do not attempt to remove or repair any component of the unit. Consult an authorized service technician for servicing / repair.
• Do not hang on doors or stand inside the unit.
• Please read through this manual in its entirety.

Cabinet Location Guidelines

• Install the unit on a strong and leveled surface.
  • If the surface is uneven, the unit may be noisy.
  • The unit may malfunction if the surface is uneven.
• Install the unit in an indoor, well ventilated area.
  • For best performance, maintain 6" of clearance on the sides and the back of the unit at all times.
  • Outdoor use may cause decreased efficiency and damage to the unit.
  • Avoid direct sunlight.
• Avoid installation in a high humidity and / or dusty area.
  • High humidity can cause the unit to rust and may decrease efficiency.
  • Dust collected on the condenser coil may cause unit to malfunction.
  • Malfunction due to high ambient temperatures, humidity, or improperly maintained condenser coil will void the warranty.
• Select a location away from heat and moisture-generating equipment.
  • High ambient temperatures may cause the compressor to malfunction.
  • Malfunction due to high ambient temperatures and humidity will void the warranty.
• If your model is refrigerated, the unit is designed to perform in a temperature-controlled environment less than 75°F and 55% relative humidity. The unit should be located away from doors, air ducts, and fans that could disrupt airflow and negatively impact performance.

Electrical

• Please ensure that the required voltage is being supplied at all times.
• The unit should be plugged into a grounded and properly-sized electrical outlet with appropriate over-current protection. Please refer to the electrical requirements on the unit's nameplate.
• The unit should have its own dedicated outlet.
• Do not use extension cords.
• Ensure the unit is not resting on or against the electrical cord.
• If the unit is not in use for a long period of time, please unplug the unit from the outlet.
• To avoid shock and fire hazards, do not plug in or unplug the unit with wet hands.
• After unplugging the unit, wait at least 10 minutes before plugging it back in. Failure to do so could cause damage to the compressor.

Defrost System

Refrigeration units contain an automatic defrost system. Refrigeration coils are kept below the freezing point (32 °F). During compressor downtime, 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.

Loading Product

• Do not block the air vents.
• 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 Condenser 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, available from any kitchen equipment retailer.

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.
• Periodically remove the shelves and shelf brackets from the unit, and clean them with a mild soap and warm water.
