FAULT
G
B
During operation, the
compressor stops for no
apparent reason.
When operating, the compressor
vibrates and the motor emits
an irregular buzzing sound.
If it stops, it does not restart
although the sound of the motor
is present.
Irregular presence of oil in the
network.
Leaking of condensate from the
vent cock.
Any other type of operation must be carried out by authorized Service Centers, requesting original parts.
Tampering with the machine may impair its safety and in any case make the warranty null and void.
CAUSE
Tripping of the thermal cutout of
the motor.

One of the phases of the
3-phase power supply is missing
