precautions should be adhered to, including the following:
p Before unit is used, it must be properly installed and operated in accordance with the
installation instruction.
p Before the unit is plugged in, ensure the rated voltage corresponds to the voltage of the
electrical system in your operation. The power plug should have its own independent socket.
Using adapters may cause overheating or burning.
p If the supply cord is damaged, it must be replaced by the manufacturer, or its service agent
or a similarly qualified person, in order to avoid a hazard.
p Connect to properly grounded outlets only. Avoid the use of extension cords. Do not run cord

3. Use of Equipment
The unit is for preserving fresh perishable food, with a built-in refrigerated unit. Do not utilize the
equipment to store medical supplies. The optimum operational temperatures are between
33°F to 40°F in refrigerators and -8°F to 0°F in freezers.
4. Technical Features
The unit is a ventilated system; the evaporator is in a separate insulated box on the top. All the materials
used in the manufacture of this unit are guaranteed to be suitable for use with food. Eco-friendly R290
hydrocarbon refrigerant. The refrigerating circuit is in compliance with the current normative
5. Operation
The gas in the refrigerating circuit is compressed, liquefied and evaporated in the ventilated evaporator,
which is situated on the top of the container.
This cycle involves the absorption of heat from the air in the refrigerator compartment and the reason is
cooled. The heat produced is dissipated to the outside environment by a condenser unit located on the
top of the unit.

6. Control Unit
The unit is operated from a digital control unit and a main switch pilot light in the top panel of the unit. The
main switch pilot light is for turning on the power supply. The green pilot light turns on to indicate that the
unit is connected to the main electricity and to start work. The green pilot light comes off to indicate that
the unit is disconnected and will not work. The digital control unit is for the regulation of all parameters to
provide the correct working of the unit. Please consult all parameters in the manual of the digital control
unit.
This manual is part of the instruction manual and is very important in case of service.
7. Handling
The unit arrives in PET film and is packed in a cardboard box on a wood pallet. The unit must be
transported and handled with care to avoid posing a hazard to persons or property. Never place unit on
its side or turn it upside down, as this may damage or impair operation of the refrigerated unit. Culitek
cannot be held liable for any damage or defects arising directly or indirectly from improper handling of the
equipment or non-compliance with the safeguards noted above.
8. Installation Procedure
Place the unit in the coolest and best ventilated part of the room. Do not install near heat sources or in
direct sunlight. Remove the straps securing the cardboard packing, the cardboard covering and the PET
protection film before installation. Clean the unit with mild detergent and then dry it with a soft cloth.
9. Connecting to Main Power Supply
This operation must be carried out by professionally and only by qualified persons. The unit is supplied
with a power supply cable for the connection to the main power supply. A thermomagnetic circuit breaker
(not supplied) must be installed between the main power point and the power supply cable of the unit.
Before proceeding make sure:
▲ The main voltage corresponds to the voltage on the unit 115V/60Hz/1Ph; to ensure proper operation
it is essential for the power supply voltage to come within a range of +/- 10% of the unit’s rated voltage.
▲ The electrical system to which the unit is sized to cater for the rated electric output of the buffet unit
being installed.
▲ The electronic system to which the unit is connected is made in compliance with current standard
requirements.
▲ The electric connections and the installation of the thermomagnetic circuit breaker have been done
by a qualified person.
Connecting steps:
▲ Install a thermomagnetic circuit breaker suited to the rated output of the unit being installed.
▲ Connect the refrigerator unit to the thermomagnetic circuit breaker outlet.
▲ Check that refrigerator unit is in order as demonstrated by the pilot light incorporated in the main
switch coming on.
