•
Check the voltage and frequency net values which
must be within the limits:
220/240 ~50HZ +/- 6%
Check that the phases unbalancing must be lower than
2%
The operating out of the limits can cause irreversible
damages and makes decay the warranty.
Voltages
Check that the air and water temperatures are within
the operating limits.
With unit at steady state, i.e. in stable and close-to-
work conditions, check:
•
supply voltage
•
unit total absorption
•
absorption of each electric load.
Remote controls / consents
Check that the used remote controls are wired and
enabled with the respective parameters :
•
ON-OFF
•
Summer-Winter
•
Silent
•
Ventilation
General
•
The indicated operations should be done by
qualified technician with specific training on the
product.
•
The service centres shall perform by request the
start-up; the electrical, hydraulic connections and
the remaining work on the system are provided by
the installer.
• Agree upon the start-up date with the service centre
sufficiently in advance .
Before checking, please verify that :
• the unit should be installed properly and in
conformity with this manual.
•
the electrical power supply line should be sectioned
at the beginning.
•
the line sectioning device is open, locked and
equipped with the suitable warning signs.
•
ensure no voltage is present .
After turning off the power, wait at least 5 minutes
before accessing to the electrical panel or any other
electrical component.
Before accessing check with a multimeter that there
are no residual stresses.
Refrigerant circuit
•
Use the pressure taps only if you need to load
or unload the refrigerant circuit.
Aeraulic system
Verify that:
• the rooms are clean (free from dirt)
• possible dampers are opened and calibrated
• the air filters are not removed from unit and are
cleaned (possible ventilation checks and the
operating starting period determinate a ducting
“cleaning” with consequent filter precocious
clogging, filters that must be cleaned and replaced)
•
ducting are completed, connected and without
obstructions
• Grilles, outlets, and diffusers must be free of
obstructions (furniture, shelves, etc.), open and pre-
calibrated, so as to ensure proper air distribution,
which is essential to comfort in the room
Electrical circuit
•
Verify that the unit is connected to the ground
plant .
•
Check tightening of the conductors: the vibrations
caused by handling and transport might cause
loosing .
•
Feed the unit by closing the sectioning device, but
leave it on OFF

PRELIMINARY INFORMATION
STARTING REPORT
Identifying the operating objective conditions is useful
to control the unit over time.
With unit at steady state, i.e. in stable and close-to-
work conditions, identify the following data :
•
Total voltages and absorptions with unit at full load
• Absorptions of the different electric loads
(compressors, fans, pumps etc)
• Temperatures and air flow of the different fluids
(water, air) both in input and in output from the unit
• The measurements must be kept and made
available during maintenance interventions.
2014/68/UE PED DIRECTIVE
DIRECTIVE 2014/68/UE PED gives instructions for
installers, users and maintenance technicians as well.
Refer to local regulations; briefly and as an example,
see the following:
Compulsory verification of the first installation:
•
only for units assembled on the installer’s building
site (for ex. Condensing c direct expansion
unit)
Certification of setting in service:
• for all the units
Periodical verifications:
• to be executed with the frequency indicated by the
Manufacturer (see the “maintenance inspections”
paragraph)
