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 11,8” (30cm). clearance from the walls and 31,5” (80
cm) from the ceiling. The room must be well ventilated.
Keep well away from sources of heat. Avoid direct sunlight
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.
Position the shelf runners in the holes in the uprights. Insert the shelves in the runners.
Note: the shelves included are n.04 of GN2/1 per each door.
The maximum load of each is 48 kg. (30kg for the 12 cu.ft)
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.
The power cord set included with the appliance meets the requirements for use in the
country of purchase. Use the power cord that shipped with the appliance (
Nema 5-15).
If this appliance is to be used in another country, purchase an AC power cord set that
is approved for use in that country
13
Use and Operational Manual
11
OPERATION
The power cord must be rated for the product and for the voltage and current marked
on the product's electrical ratings label. The voltage and current rating of the cord
should be greater than the voltage and current rating marked on the product.
Do not use reductions or multi-way adapters (Fig.1)
It is important to connect the equipment correctly to an efficient earth system
executed in compliance with the relevant legislation.
The equipment must be positioned so that plug can be easily reached (Fig. 1)
Fig. 1
If the SUPPLY CORD is damaged, it must be replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid a hazard.
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 gradually to allow correct refrigeration. Perform routine
maintenance regularly.
2.5 RE- INSTALLATION

3.2 REGULATION
Once set a desired temperature required for the products storage within the operational range of
each models, the regulation of the cooling system is controlled by the temperature measured by
the control probe with a positive differential from the set point: when the temperature rises up to the
set point plus differential the compressor starts to pull down the temperature and it turns off when
the desired set point is reached again.
In case of faulty probe the compressor activation is timed through the parameter “C4” and “C5”

Prohibited to remove the guards and safety devices: It’s strictly forbidden to remove
guards or safety devices when performing routine maintenance operation. The manufacturer
disclaims all liability that may arise this regulation is not observed.
In case of FIRE
:
- Disconnect the unit from the electrical power socket.
- Do not use water to extinguish the fire.
- Use powder or foam extinguishers.
4.1.1 Cleaning the interior and exterior of the appliance
The appliance is designed for the products storage so it is important to keep it clean. The
equipment is thoroughly cleaned at the factory before being shipped. We recommend, however, to
clean the interior cabinet before the first start up of the appliance. Before attempt any cleaning
operation make sure the power cord is disconnected.
-Cleaning product: use soft clean cloth wet with water and neutral detergent only.Do not use
solvent or bleach.
-Rinsing: use a cloth or sponge soaked with fresh clean water. Do not use water jet.
-Frequency: once a week or at different intervals in accordance with the type of product.
4.1.2 Sliding door’s rails cleaning.
Keep clean the sliding door housing to avoid the door can’t close completely. Use a soft clean cloth
or a soft brush in order to remove any residuals can block the door to slide in the full closure
position.
4.1.3 Condenser cleaning
The condenser is a heat exchanger. If it is dirty or clogged the air cannot circulate freely through
the same, it cannot discharge heat properly so reducing proportionally the performance and the
efficiency of the refrigeration system.
FOR THOSE REASONS IT IS IMPORTANT TO KEEP CLEAN THE CONDENSER COIL,
TYPICALLY MONTHLY.
Use and Operational Manual
28
Always switch off the unit and disconnect power cord before cleaning, it is dangerous
to do it with power ON: fan may start suddenly at any time.
Use a convenient ladder to reach the condenser. Use an air jet or vacuum with a soft dry brush if
necessary and remove any dust or fluff from the heat exchanger fins.
After cleaning, start the equipment.
During the cleaning operation wear gloves and safety glasses to protect yourself from any
injury
