Installation
CABINET LOCATION GUIDELINES
• Install the unit on strong and leveled surfaces.
- Unit may make unpleasant noises if surface is uneven.
- Unit may malfunction if surface is uneven.
• Install the unit in an indoor, well-ventilated area.
- Unit performs more efficiently in a well-ventilated area.
- For best performance, please maintain clearance of 6” on the back of the unit.
- Outdoor use may cause decreased efficiency and damage to the unit.
• Avoid installation in a high humidity and/or dusty area.
- Humidity could cause unit to rust and decrease efficiency of the unit.
- Dust collected on condenser coil will cause unit to malfunction. Clean the condenser at least once a
month with a brush or clean cloth.
- Malfunction due to dirty condenser will void warranty.
• Select a location away from heat and moisture-generating equipment.
- High ambient temperature will cause the compressor to overwork, leading to higher energy bills and
gradual breakdown of the unit.
- Malfunction due to high ambient temperature will void warranty.
ELECTRICAL
Please ensure that the required voltage of the compressor is being supplied at all times. Low or high voltage
can detrimentally affect the refrigeration unit. All units should be plugged into a grounded and properly-sized
electrical outlet with appropriate overcurrent protection. Please refer to the electrical requirement on the
nameplate of the unit. Please make sure that your unit has its own dedicated outlet. Do not use an extension
cord.
TEMPERATURE CONTROLS
The temperature controls are factory-set to maintain an average temperature of 38°F in refrigeration. To
maintain a different temperature, adjust it on the temperature controller– see manual of temperature controller.
CAUTION
Setting the temperature control to the coldest setting may cause the evaporator coil to freeze and ice up. This
will eventually result in a warmer cabinet temperature.
LOADING PRODUCT
Shelves have been factory-installed for your convenience. Before loading shelves, please be sure that all shelf
clips are completely fastened in their correct locations. It is important that all shelves rest completely level
before stocking your cabinet with product. In order to maintain correct air flow inside the unit, please be sure
to leave two to four(2 to 4) inches of space between the back wall and stored product. Blocking the evaporator
fans will result in a warmer cabinet temperature, and ultimately compressor failure.
