Information for the installation
technician
Before starting up the machine, check that
it has been correctly installed and commis-
sioned (test report).
1. Check that there are no gas leaks from
weldings or joints made during installa-
tion works.
2. Check that the pipes connecting the
condenser to the remote condensing
unit have been well insulated.
3. Check all wiring connections.
4. Check electrical input.
5. Check the standard pressure in the
refrigerant system.
6. Check the water connections and effi-
ciency of the pressure switch valve dur-
ing operation, as well as the flow of con-
densing water (in water-cooled units).
7. Perform at least one blast freezing cycle
(to the SET temperature) and one manu-
al defrosting cycle.
In the event that the appliance or the
remote condensing unit have not been
transported in a vertical position (e.g. on
the back) or have been overturned during
installation works, allow at least 4 hours
before starting up the equipment.
• Inform the customer of the exact purpose
of the appliance, with specific reference
to the use and requirements of the cus-
tomer.
The appliance must be installed and put
into service by a technician authorised.

Safety and control systems
• Door microswitch: shuts down fan opera-
tion in the cell when the door is opened.
• General fuses: protect the power circuit
against short circuiting and overloads.
• Compressor heat relay: intervenes in the
event of overloads or operating faults.
• Safety pressure switch: intervenes in the
event of excessive pressure in the refrig-
erant circuit.
• Plug fuses: intervene in the event of over-
pressure or operating fault in the safety
pressure switch (see above).
• Chamber temperature control: operated
by the electronic board by means of a
probe inside the cell.
• Temperature control end defrost cycle:
controlled by the electronic board by
means of the probe in the evaporator.

Disposal of waste electronic
and electrical equipment (WEEE)
Fulfilling
Directives
2002/95/CE,
2002/96/CE and 2003/108/CE on the dispo-
sal of waste electronic and electrical
equipment.
The crossed out wheeled bin sym-
bol indicates the product must be
collected separately from other
waste when it has become redun-
dant. Differentiated collection of
this equipment is arranged and
handled by themanufacturer.
Consequently, the user who is wanting to
dispose of this equipment must contact the
manufacturer and follow the method the lat-
ter has adopted to allow separate collection
of the redundant equipment.
Appropriate differentiated collection for the
subsequent recycling, treatment and eco-
friendly disposal of the dismantled equip-
ment prevents possible negative effects on
the environment and health and facilitates
the recycling of materials used in manufactu-
ring the equipment.
Administrative sanctions foreseen by the
regulations in force shall be applied for any
abusive disposal of the product by the hol-
der.
