Section 3
Installation
Part Number: 9291000 06/22 15
The electric connecting cables must be dimensioned
in accordance with the rules in force in the country
of installation. In cases where the power cord of the
appliance is damaged, it must be replaced with another
with characteristics that comply with the rules in force in
the country of installation and performed by a qualified
personnel in order to prevent any risk to persons.
The earthing conductor must be correctly connected to
an efficient earthing system.
The manufacturer declines any responsibility and any
warranty obligation in the event of damage to the
equipment, to persons and property caused by incorrect
installation and/or failure to respect the applicable laws.
Remote group refrigerator connection (if applicable)
The diameters of the supply lines of the equipment
are sized for distances of up to 10 meters. Contact the
manufacturer for longer distances.
Condensate drainage connection (if applicable)
It is necessary to provide a drainage pipe for the
condensation and washing water of a minimum diameter
of 1”. It is advisable to dispose of the condensate through an
open drain at ground level and fitter with a siphon with a
minimum diameter of 1/2”.
Notes for the installer
• Verify the correct installation and system testing before
starting up the machine (test report).
• Check for any gas leaks from the welds or joints made
during the installation phase.
• Check the efficient insulation of the connecting pipes
between the condenser and the remote condensing
unit.
• Check the electrical connection
• Check the electrical input
• Verify the standard pressures of the refrigerating system
• Check the water connections with adjustment of the
pressure valve during operation and good circulation of
the condensation water (water cooled groups).
Commissioning
,
Commissioning must be carried out by
authorized and qualified personnel.
Perform at least one complete cycle of rapid storage
freezing (to reach the SET temperature), and a manual
defrost cycle. If the equipment or the remote condensing
units were not delivered in an upright position (e.g. on
their back) or were overturned during installation, do not
turn on immediately but wait at least 4 hours before use.
Inform the customer of the exact use of the equipment
with specific reference to the use and to customer
requirements.
Safety and control systems
• Door micro switch: this locks operation of the fans in the
cell when the door is opened.
• General protection fuses: they protect the entire power
circuit against short circuits and possible overloads.
• Compressor thermal relay: this intervenes in case of
overloads or malfunction.
• Safety pressure switch: this operates in the case of
excess pressure in the refrigerant circuit.
• Fusible plug: this intervenes in the case of overpressure
and failure of the afore-mentioned safety pressure
switch.
• Chamber temperature control: this is operated by the
electronic card via the probe positioned inside the cell.
• Defrost termination temperature control: this is
managed by the electronic card via the probe located
on the evaporator.
Stop modes
In an emergency, to stop the machine remove power from
the main panel using the earthing switch or by removing
the plug from the socket making sure hands are not wet or
damp.
