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 75ºF 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 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 all accessories are installed (shelves, shelf clips, etc…) before plugging in the unit.
• Do not attempt to remove or repair any component of the unit. Consult an authorized service technician for servicing / repair.
• Do not stand inside the unit.
• Please read through this manual in its entirety.
• This refrigerator is designed to perform in a temperature-controlled environment at 65% relative humidity. The unit should be located away from doors, air ducts, and fans that could disrupt airflow and negatively impact performance.

Cabinet Location Guides

• 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 away from doors, air ducts, and fans.
  • For best performance, maintain 6” of clearance on the back of the unit at all times.
  • Do not use outdoors. For indoor use only.
  • 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.

Position the Merchandiser at its final location before removing the shipping skid. There are four bolts at the bottom of the merchandiser that secure the shipping skid. Keep the unit lifted, remove all four bolts to remove the skid

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 or freezer 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 +4 degrees 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.

Refrigerator Control

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 (snowflake symbol and 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 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. Freezer coils are defrosted electrically. Automatic defrost timers automatically initiate at pre-set intervals and for a pre-determined duration. To use the merchandiser more safely and energy efficiently, the drainage pipe behind the unit
is strongly recommended to a physical drainage line. The drip tray may flood at high humidity circumstance! If you find the unit is leaking water, please check if the drip tray floods. Please connect with the drainage outlet to avoid flooding.

Operation/Maintenance

NOTE: We strongly recommend that any servicing be performed by an authorized service technician.

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. Do not block return air flow in the front of the unit.

• 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, 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.

A dusty condenser may lead to high energy consumption, less cooling effectiveness, and compressor damage.

Condenser Coil Cleaning Instructions:
The condenser coil is located at the bottom behind the panel.

1. Disconnect the electrical power from the unit.
2. Remove the front cover and base cover with screwdriver.
3. Brush the dirt, lint, etc. from the finned condenser coil.
4. When finished, be sure to reinstall the front cover and base cover.
5. Reconnect the electrical power to the unit.

• The air curtain is being disturbed by strong air flow.
  Make sure the cabinet is located away from doors, windows, and other air vents.

• High ambient temperature or humidity.
  This refrigerator is designed to perform in temperature-controlled environment up to 75°F and 65% relative humidity.

Cabinet Temperature is Fluctuating

• Condenser coil is dirty.
  Clean the condensor coil.

• Unit has improper air flow.
  Make sure the unit has at least 6″ of clearance on the back and that the front vents are not obstructed.
