PLEASE READ THE MANUAL THOROUGHLY PRIOR TO
EQUIPMENT SET-UP, OPERATION AND MAINTENANCE.

INSTALLATION/ OPERATION
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 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 efficiently in a well-ventilated area
-for best performance, please maintain clearance of 30 mm 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 temperatures 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 requirements 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 0 C in
refrigerators. To maintain a different temperature, simply adjust the thermostat is located
at the control panel on the basis of operation manual inside of cabinet.
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 50 mm to 100
mm 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 (0 C). 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.
PLEASE NOTE: Excessive door openings should be avoided in order to maintain
cabinet temperature and to eliminate the possibility of coil freeze-up.
All electrical work must be carried out by suitably qualified persons

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 when the unit is required to be 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 least 10 minutes before re-plugging it. 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.
PROPER GROUNDING REQUIRED
■To minimize shock and fire hazards, make sure that the unit is properly grounded.
PROHIBITION
■Do not attempt to remove or repair any component unless instructed by factory.
■Make sure that the unit is not resting on or against the electrical cord and plug.
■To minimize personal injury, do not hang on the doors.
■Do not store any flammable and explosive gas or liquids inside the unit.
■Do not attempt to alter or tamper with the electrical cord.

REGULAR MAINTENANCE
CLEANING THE CONDENSER COIL
■For efficient operation, it is important that the condenser surface be kept free of dust,
dirt, and lint.
■We recommend cleaning the condenser coil and fins at least once per month.
■Clean with a commercial condenser coil cleaner, available from any kitchen
equipment retailer. Brush the condenser fins from top to bottom, not side to side.
■After cleaning, straighten any bent condenser fins with a fin comb.
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 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, first 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.
