Installation

Please read this manual thoroughly prior to equipment set-up, operation and maintenance.
Important!!! Please Read Before Installation

• I f 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 precooled to the proper temperature before loading the unit with product.
• 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

• I nstall 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.

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 degrees fahrenheit). 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.The refrigeration units contain an automatic defrost system.

Use
High liquid content foods should be limited to 50% capacity of the machine’s total cooling capacity.To avoid surpassing the internal pressure limit of the compressor, and extend the life of the compressor, allow the unit 2 minutes in between cycles. After 2 minutes, press start/stop button, the compressor will start, and after another 2 minutes the evaporator fan starts.

In the quick freeze modes, if the start/stop button in pressed, and the temperature of the cabinet is less than the set temperature, the compressor will not start until the temperature is greater than or equal to the set point.

Cabinet probe high Temperature Alarm (Temperature over 113°F)

| Press the START/STOP button to start the cooling. After 2 hours, check the temperature inside the cabinet. If the cabinet temperature is greater than or equal to the high temperature alarm temperature of 45 °C / 113 °F, the temperature display column alternately displays the cabinet temperature and HI until the temperature is lower than the alarm temperature. At this time, check whether the door of the machine is closed, or stop the machine to check whether the temperature probe or compressor is faulty.

LO

| __

Cabinet probe low Temperature Alarm. (Temperature under -49°F)

| Press START/STOP to START the refrigeration, and test the temperature inside the cabinet 2 hours later. If the temperature of the cabinet is less than or equal to the low temperature alarm temperature of -45°C/-49°F, the temperature display bar will alternately display the temperature of the cabinet and LO until the temperature is higher than the alarm temperature. At this time to stop the cabinet temperature probe and other devices to check whether there is a fault.

• Do not use trays or containers deeper than 25/8″.
• Do not stack food. The thickness of the food product should not be more than 15/8″.

Cleaning the Condenser Coil and Filter

• For efficient operation, keep the condenser surface free of dust, dirt, and lint.
• We recommend cleaning the condenser coil and filter at least once per month.
• Clean the condenser with a commercial condenser coil cleaner such as Noble Chemical Tech Line Evaporator/Condenser coil cleaner.

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 such as Noble Chemical Sunbright and Sani-512 to sanitize/disinfect.
• 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.
