Electric Circuit
Verify that the unit is connected to the ground plant.
Check the conductors are tightened as: the vibrations caused by
handling and transport might cause these to come loose.
Connect the unit by closing the sectioning device, but leave it on
OFF.
Check the voltage and line frequency values which must be within
the limits: 400/3/50 +/- 10%
Check and adjust the phase balance as necessary: it must be
lower than 2%
NOTE

Working outside of these limits can cause irreversible
damages and voids the warranty.
Compressor crankcase heaters
Power the compressor oil heating resistors for at least 8 hours before starting the compressor itself:
 upon unit commissioning

after every prolonged stop period with unit not powered
1 Power the resistors by closing the unit isolator.
2 Check electric absorption of the resistors to be sure they are working.
3 Execute start only if the temperature of the compressor casing on the lower side is at least 10°C higher
than the outdoor temperature.
4 Do not start the compressor with carter oil not in temperatureTensioni
Voltages
Check that the air and water temperatures are within in the operating limits.
Start-up the unit.
With unit operating in stable conditions, check:

Voltage
 Total absorption of the unit

Absorption of the single electric loads
Scroll compressor
The Scroll compressors have only one rotation direction.
In the event it is reversed, the compressor is not immediately damaged, but increases its noise and
jeopardises pumping.
After a few minutes, the compressor blocks due to intervention of the thermal protection.
In this case, disconnect power supply and invert 2 phases on the machine power supply.
Avoid the compressor working for a long time with contrary rotation: more than 2-3 of these anomalous
start-ups can damage it.
To ensure the rotation direction is correct, measure the condensation and suction pressure.
The pressures must significantly differ: upon start-up, the suction pressure decreases whereas the
condensation one, increases.
The phase monitor optional, controlling the phases sequence, can also eventually be installed subsequently.
Remote controls
Check that the remote controls (ON-OFF etc) are connected and, if necessary, enabled with the respective
parameters as indicated in the “electrical connections” section.
Check that probes and optional components are connected and enabled with the respective parameters
(“electrical connections” section and following pages).
