COMMISSIONING AND MAINTENANCE
3 COMMISSIONING AND MAINTENANCE
3.1 Preparation for first commissioning
Prior to commissioning, it is necessary to check that:
—
all the safety conditions have been met
— installation distances and gaps have been respected
— the indoor units have been connected to the respective
refrigerant and electric circuit
— the electrical connections have been properly completed
— power supply values are correct.
— the earthing has been carried out correctly
— all the connections have been properly tightened
— the shut-off valves are open

The device must always be powered electrically in order to
allow for the compressor's oil to be properly pre-heated.
If the device is installed in very cold areas, the device should
be under voltage for at least 12 hours before starting it up
for the first time.

— position the system's main switch in the "ON" position.
— carry out the verification procedure of the electrical con-
nections
Verification procedure of the electrical connections
The device can perform an automatic procedure to check the
correct electrical connection between the outdoor unit and the
internal units. The procedure is activated by the signal panel.

• To verify:
—
access to the terminal panel
— check chapter "Electrical connection" p. 30
— operate on the signal panel
— set the microswitch "ON"
— position the system's main switch in the "OFF" position.
— wait few second
— position the system's main switch in the "ON" position.
After 3 minutes, the system enter into verification mode.
After 30 to 50 minutes, the verification ends and the result is
displayedthrough the signal LEDs:
Led off: connection missing
flashing LED: incorrect connection
Led on: correct connection

If there is a wrong connection, will flash the LEDs of the units
involved. In this case, check carefully connections and re-
verse the wrong ones.

If only one LED flashes, there may be a malfunction of the
signal panel.
3.2 Putting into service
After having completed all the operations required to prepare
