THIS MANUAL HAS BEEN PREPARED FOR PERSONNEL QUALIFIED TO INSTALL,
MAINTAIN AND REPAIR ELECTRICAL REFRIGERATION EQUIPMENT, WHO SHOULD
PERFORM THE INITIAL FIELD STARTUP AND ADJUSTMENTS OF THE EQUIPMENT
COVERED BY THIS MANUAL.
READ THIS MANUAL THOROUGHLY BEFORE OPERATING, INSTALLING, PERFORMING
MAINTENANCE ON, OR REPAIRING THE EQUIPMENT.
WARNING Failure to follow all the instructions in this manual can cause property
damage, injury or death.
WARNING Improper installation, adjustment, alteration, service or maintenance can
cause property damage, injury or death.
WARNING Electrical connections should be performed only by a certified professional.
Electrical and grounding connections must comply with the applicable portions of the
National Electric Code and/or all local electric codes. Failure to comply with this
procedure can cause property damage, injury or death.
WARNING Before connecting the unit to the electrical supply, verify that the electrical
and grounding connections comply with the applicable portions of the National Electric
Code and/or other local electrical codes. Failure to comply with this procedure can
cause property damage, injury or death.

2. INSTALLATION
2.1 TRANSPORTATION AND HANDLING
The equipment must be transported and handled exclusively in upright position, in
observance of the instructions printed on the packing.
This precaution is necessary to avoid contamination of the refrigerant circuit with compressor lube
oil with resulting valve and heat exchanger coil failure and problems starting the electric motor or
the risk of a gas leak. The manufacturer is not responsible for any problems due to transport
executed in conditions other than those specified herewith.
The equipment is secured to a wooden pallet base, wrapped in a plastic film and packaged into a
three waves carton box..
The equipment must be handled using a fork lift truck or a pallet truck with suitable forks (fork
length at least equal to 2/3 length of unit).
2.2 POSITIONING
Incorrect positioning can cause damage to the equipment and generate hazardous conditions for
personnel. The installer must therefore observe the following general regulations:
 Make sure you maintain a minimum of 11 13 16  inches (30 cm). clearance from the back wall,
19 43 54
” (50 cm) from the side walls and the ceiling. The room must be well ventilated.
 Keep well away from sources of heat. Avoid direct sunlight exposure.
 Remove packing material.
 Remove accessories from inside the unit.

 Cartoon box or Wood base removal: using a hammer, tilt the cabinet to one side and loosen
the two thread-forming screws, drag the cabinet from the back side holding the base still until
the four castors have gone out from the containing holes, slightly tilt the cabinet backward and
take the base away pulling it from the front side.
Use gloves when handling the 3 Waves cartoon box or the wooden base to protect the hands
from splinters.
 Position the equipment with the help of a level. Remove the protective PVC film from the
external surfaces of the unit.
2.3 WIRING AND ELECTRICAL HOOK-UP
Receptacle installation and electrical wiring operations must be performed by a qualified
electrician. For safety reasons adhere to the following indications:
 Check that the electrical plant is suitably sized for the absorbed power of the unit.
 If the electrical socket and the plug on the equipment power cord are incompatible, call
technical service or your local distributor.
 Do not use reductions or multi-way adapters
It is important to connect the equipment correctly to an efficient earth system executed
in compliance with the relevant legislation.
A switch or circuit-breaker must be included in the installation:
 it must be suitably located and easily reached;
 it must be marked as the disconnecting device for the equipment.
2.4 SET UP OPERATIONS
To avoid errors and accidents, perform a series of checks for possible damage sustained during
transport, installation and hook-up operations before starting up the unit.
PRELIMINARY CHECKS
 Check the condition of the power cord (no cut or chaffing). Check that the door hinges and
shelf support are stable.
 Check the door seals and shelves are not damaged (broken or scratched) and that the door
closes and seals properly.
 Make sure all copper tubing, unions are in perfect condition.
FOR OPTIMAL PERFORMANCE
 Do not block the motor compartment air vents. Do not lay objects on the top of the equipment
Before storing products wait until they are cold.
 Arrange the products on suitable shelves or in containers. Do not place products directly on
the base or against the walls, doors or fixed guards of the unit.
 Make sure doors are kept closed.
 Keep the defrost water drain outlet clear.


Limit the frequency and duration of opening; each time the door is opened the internal
temperature will alter.

Load products at ambient temperature
