COMMISSIONING AND TESTING

COMMISSIONING PROCEDURE
Arm the cutout in the auxiliary circuits;
Arm all the cutouts on the electrical panel;
Power up the air-conditioner electrical panel and close the main
disconnecting switch on the unit (position 'I');
Check that the control board is powered; Check that both the
LEDs relating to the phase sequence relay (RSF) are on; the yel-
low LED indicates power, the green LED indicates that the
sequence of phases is correct.
If the green LED is off, disconnect power supply from the units,
reverse two phases of the power cable and restart the commis-
sioning procedure. (In the units with sump heaters)
After having powered up the air-conditioner, wait at least 12
hours before starting so as to suitably heat the oil in the com-
pressors. During extended shutdown there may be spontaneous
migration of refrigerant to the compressor sump, which at the
start may cause the oil to foam and consequent damage due to
insufficient lubrication.
As a result, do not disconnect power during weekly pauses;
Open the on-off valves in the refrigerant circuits and check that
the air-cooled remote condensers are connected (air-cooled
models); Check that the external radiators are connected and
make sure there is water flow for cooling (water-cooled models);
Check that the sections of corrugated pipe with the function of
drain trap (both inside and outside of the air-conditioner) have
been filled with water during installation.

AT LEAST 12 HOURS AFTER POWER UP:
Start the air-conditioner using the buttons on the user terminal;
If an alarm is activated refer to the controller instruction
manual.
