Installation

Please read this manual thoroughly prior to equipment setup, operation, and maintenance.

This unit is intended for use in a temperature-controlled environment less than 75°F and 60% relative humidity. Malfunction due to improper conditions is not covered under warranty.

Important! Please Read Before Installation

• If the shelf has a raised lip, the lip needs to be installed facing up towards the rear of the cabinet to promote proper airflow. Failure to install the shelves properly is considered user error and is not covered by warranty.
• 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 that the unit has reached the desired temperature before loading the unit with products. This unit is meant for keeping cold products cold, not chilling warm products.
• Make sure that there is proper ventilation around the unit in the area where it will operate.
• Make sure all accessories are installed (i.e., shelves, shelf clips, casters) before plugging the unit in.
• Do not attempt to remove or repair any component of the unit. Consult an authorized service technician for servicing/repair.
• Do not sit/stand on or inside the unit.
• Please read through the manual in its entirety.
• This unit is designed to perform in a temperature-controlled environment at 60% relative humidity. The unit should be located away from doors, air ducts, and fans that could disrupt airflow and negatively impact performance.

Cabinet Location Guidelines

• Install the unit on strong and leveled surfaces.
  – 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, always maintain 6″ of clearance on both sides and the back of the unit.
  – Do not use outdoors. For indoor use only.
  – Avoid direct sunlight.

• Avoid installation in a high humidity and/or dusty area.
  – Humidity above 60% can cause the unit to rust, collect condensation, and may decrease product efficiency.
  – Dust collected on condenser coil will cause unit to malfunction.
  – Malfunction due to temperatures above 75°F, humidity above 60%, or improperly maintained condenser coil will void the warranty.

• Select a location away from heat and moisture-generating equipment.
  – Ambient temperatures above 75°F may cause the compressor to malfunction.
  – Malfunction due to ambient temperatures above 75°F will void warranty.
  – Do not install the unit inside a closet or alcove.

Installation of Casters:

• Cut the two straps which attach the unit to the pallet.
• Adjust the unit on the pallet until the pre-drilled holes are exposed.
• Using wedges or team-lift, lift the unit high enough that there is enough clearance to affix the caster.

CAUTION! NEVER LAY UNIT ON ITS BACK! UNIT SHOULD ONLY BE PLUGGED IN WHEN IT HAS RESTED IN THE CORRECT UPRIGHT POSITION FOR AT LEAST 24 HOURS. Failure to meet the requirement will void warranty coverage if compressor damage ensues.

• For leveling, if dealing with a sloped or uneven floor, shims are provided. Insert any necessary shims between the caster and the frame rail. Make sure the slot of the shim is in contact with the treaded stem of the caster. If using more than one shim, it is necessary to place them in opposite directions. If multiple shims are placed side by side in the same direction, they may dislodge.
• Turn the bearing race clockwise to tighten and secure the caster. Use provided tool to secure all casters properly.

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.

Adjusting the Temperature:

• Your new refrigerator is already factory-set to run at optimum temperatures for food safety and should require no adjustments.
• Refrigerators are set to cycle between a minimum temperature of 33°F and a maximum temperature of 40°F
• Adjusting the temperature changes the minimum temperature your unit will run at. Your unit will not run constantly at this setting. To change it, follow these instructions:

Digital Control Units

• Hold “SET” for 1 sec. The display will flash the current minimum temperature.
• Use the arrow buttons to adjust the minimum temperature you want it to run at.
• Press “SET” again to save your settings.

Always remember to calculate the differential if you change the minimum temperature setting. The cabinet temperature will fluctuate up to +6°F over your set minimum temperature as the compressor runs and shuts off. Setting the temperature too high will result in unsafe maximum temperatures and possible health code violations.

Running a Manual Defrost Cycle

This unit is pre-programmed to run automatic defrost cycles at preset intervals. However, if you would like to run a manual defrost cycle at any time, please follow the steps below:

Refrigerators: Press the defrost button (down arrow) for approximately 3 seconds. Repeat to stop the defrost cycle.

Defrost System

Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). During compressor down-time, the evaporator fan continues to circulate air though the evarporator 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. Automatic defrost timers automatically initiate at pre-set intervals and for a pre-determined duration.

Safety/Warning

Please pay close attention to the safety notices in this section. Disregarding these notices may lead to serious injury and/or damage to the unit.

Attention

• To minimize shock and fire hazards, be sure not to overload outlet. please designate one outlet for your unit.
• Do not use extension cords.
• Do not put your hands under the unit while it is being moved.
• When the unit is not in use for a long period of time, please unplug the unit from the outlet.
• After unplugging the unit, wait at leaset 10 minutes before plugging it back in. Failure to do so could cause damage to the compressor.

Unplug Cord

• To minimize shock and fire hazards, please do not plug or unplug the cord with wet hands.
• During maintenance and cleaning, please unplug the unit.
