•
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
•
Check the voltage and frequency net values which
must be within the limits:
230 / 1 / 50 +/- 10%
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
•
Visually check the refrigerating circuit: the presence
of oil stains can mean leakage (caused, for
example, by transport, handling or other).
•
Use the pressure taps only if you need to load
or unload the refrigerant circuit.
Hydraulic circuit
If the humidifier is present:
•
Before realizing the unit connection make sure that
the hydraulic system has been cleaned up and the
clearing water has been drained .
•
Check that the water circuit has been charged and
pressurised .
•
Check that the cut-off valves on the circuit are in
the "OPEN" position.
•
Check that no air is present in the circuit, if
required, evacuate using the air bleeding valve
placed at the system's high points.
Aeraulic system
Verify that:
•
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
7 - START-UP
7.1 PRELIMINARY INFORMATION
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
•
Electric resistances
•
Humidifier
Check that the phases unbalancing must be lower than
2%
