Installation
IMPORTANT!!!PLEASE READ BEFORE INSTALLATION
• If the unit has recently been transported. Please let unit stand still for a minimum of 24 hours before
plugging it in.
• Make sure that the unit drops down to desired temperature before loading the unit with product.
• 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.
• Please read through the Operation / Owner’s Manual in its entirety.
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 efciently in a well-ventilated area.
- For best performance, please maintain clearance of 3” on the back of the unit.
- Outdoor use may cause decreased efciency and damage to the unit.
• Avoid installation in a high humidity and/or dusty area.
- Humidity could cause unit to rust and decrease efciency 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
7
Installation
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 ow 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.
DEFROST SYSTEMS
Refrigerator coils are kept below the freezing point(32°F). 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 are built-in to the refrigeration system and may
not be adjusted. The defrost timers automatically initiate at pre-set intervals and for a pre-determined duration.
PLEASE NOTE: Excessive door opening should be avoided in order to maintain cabinet temperature and to
eliminate the possibility of coil freeze-up.
LOADING FOOD PANS
Pizza prep units and sandwich prep units are designed to function with all pans in place, even if some pans are
to be left empty. For maximum food freshness, Fill the pans only with an amount that can be used in a specic
usage period. During non-use, please close the insulated lid cover.
Maintenance
CLEANING THE CONDENSER COIL
• For efcient operation, it is important that the condenser surface be kept free of dust, dirt, and lint.
• We recommend cleaning the condenser coil and ns at least once per month.
• Clean with a commercial condenser coil cleaner, available from any kitchen equipment retailer. Brush the
condenser ns from top to bottom, not side to side.
• After cleaning, straighten any bent condenser ns with a n comb.
CLEANING THE FAN BLADE 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.
8
Maintenance
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 stainless steel
surface.
• Wash door gaskets on a regular basis, preferably weekly. Simply remove door gasket from the frame of the
door, soak in warm water and soap for thirty (30) minutes, dry with soft cloth, and replace.
• Check door gaskets for proper seal after they are replaced.
• Periodically remove the shelves and pilasters from the unit and clean them with mild soap and warm water.
To remove the pilasters, rst remove the shelves and shelf brackets. Then, simply lift the pilaster up and
out.
WARNING
Disconnect power cord before cleaning any parts of the unit.
