6. HANDLING AND STORAGE (SPECIALIST TECHNICIAN)
6.1 HANDLING
The loading and unloading operations must be performed by qualied sta,
who will verify the exact weights and lifting points; they will use lifting
equipment which is safe and with a suitable carrying capacity. There must be
no individuals who are not involved in the operation close to the lifting points.
Fig. 1
The package must be lifted by inserting
the forks of the lift truck into the space
between the legs of the pallet or crate.
The weight of the equipment must be
divided so that the centre of gravity of
the package remains balanced (Fig.1-A).
Do not tip the equipment over.
PROHIBITED LIFTING MEANS
Lifting means or equipment which do not respond to the safety requirements must not be used.
These include:
• lifting capacity lower than the weight of the equipment;
• unsuitable construction features of the forklift truck (e.g. short forks);
• construction features altered by use;
• non-compliant ropes or cables;
• worn-out ropes or cables.
Any other handling procedure dierent to those described in this
chapter are prohibited.
Before inserting the forks of the lift truck, verify that these cover
the entire depth of the package (Fig. 1-B).
If not, install appropriate extensions.

6.2 STORAGE
The equipment must be stored in a dry humidity-free environment.
It must be covered with a sheet before storage to protect it from dust or dirt.
The maximum storage temperature is
55°C.
If the appliance (only packages with

7. AMBIENT CONDITIONS FOR INSTALLATION
The equipment must be installed in a closed environment, covered
and safe from atmospheric agents.
The equipment must not be installed in areas containing explosive
substances.
25°C
60%
Position the equipment far from draughts (fan-coil,
fans, windows, air outlets).
Avoid exposing the equipment to direct sunlight,
to concentrated light units or to sources of heat
such as radiators, stoves or ovens.
Ensure there is sucient air circulation on all sides
of the cabinet.
It is absolutely forbidden to position objects
around the counter which can in some way hinder
the circulation of air over the condensing unit.
Failure to comply with the above requirements
can, in addition to the fast deterioration of the
materials composing the cabinet, cause poor
operation of the cabinet, including:
• Higher energy consumption.
• Mist formation on the cold surfaces (glazing or countertop).
• Poor preservation of the foods of the counter and the risk of making the displayed goods
deteriorate.
The ambient temperature must fall within the temperature limits established by the class of
equipment (25 °C - 60% of humidity). If these limits are exceeded the performance of the
equipment will be lower.

8. FIRST START-UP (OPERATOR)
8.1 PRELIMINARY CLEANING
Wear protection gloves when carrying out the jobs explained in this
chapter.
Clean the display unit thoroughly prior to starting it up.
Cleaning instructions are provided in chapter “CLEANING”.
8.2 FIRST START-UP
• Counter with Temperature electronic controller or Electronic control valve
1Unscrew to
lower the
protection
In order to turn on the refrigeration function, please push the switch identied by the symbol
in g. 1.
Cabinet functions (defrosting, cooling, etc..) are controlled by the electronic thermostat, if this
is provided.
The cabinet is pre-set to provide an air temperature at inlet specied in the set para-
meter table.
To program a dierent temperature, refer “SET POINT MODIFY”.
Defrost-related settings are pre-set for standard conditions.
In case of other conditions such settings must be adjusted.
The foods must be loaded onto the cabinet only when the temperature
et point has been reached.

Before loading the foods in the cabinet, remember to adjust the thermal-
expansion valves
• Counter without Temperature electronic controller or electronic control valve.
In this case, the refrigeration function is turned on in remote type by the store
control device.
8.2.1 ADJUSTMENT OF THE EVAPORATOR FANS
The change in speed of the evaporator fans, in the sections where this is allowed, to values
dierent to those set in the factory (see technical specications), compromises the correct
operation of the cabinet.
The operations described in this chapter must be carried out by
qualied sta.
Pay close attention: presence of electric voltage.
To adjust the speed of the fans it is necessary to access the interior of the electric board.
For the methods to access the electric board, refer to what is specied in the chapter
“ELECTRIC CONNECTIONS”
With the electric board open, identify the speed regulator (REG) and the terminal box X21 (see
g. 1)

The regulation is necessary for the correct operation of the cabinet, in particular with the remo-
te or centralised condensing unit.
Regulate only when the temperature inside the cabinet has stabilised. To avoid the cabinet
cycling (on/o) set a SET temperature of -1°C (see instructions of the electronic Thermostat).
To regulate the valve it is necessary to measure the expansion temperature (T1) and the
evaporator outlet temperature (T2).
• To measure the expansion temperature (T1) connect a pressure switch (A) to the
charge/discharge valve under the cabinet in correspondence of the valve.
If the cabinet is not equipped with a charge/discharge valve, position the thermometer probe
(B) in the rst bend of the evaporator after the expansion valve (Fig. 5) (see g. 3 and 4 on
the xing methods).
• To measure the outlet temperature (T2) position the thermometer probe (B) on the
pipe next to the valve bulb, as specied in g. C and D.
Check that the dierence of temperature (T1 –T2) is between 4°C and 5.5°C; in this case, the
valve does not need to be regulated.
• If T1-T2 is greater than 5.5°C (example 8°C), the valve must be open.
• If T1-T2 is less than 4°C (example 2°C), the valve must be closed.
Once the regulation is made, check that the expansion temperature is lower than -9°C (exam-
ple -10°C…12°C).
CAUTION: expansion temperatures that are too low can dry out the product on display.
