FAULT
After an attempt to start the
compressor, it stops due to tripping
of the thermal cutout caused by
forcing of the motor.
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
Start-up with head of the
compressor charged.
Low temperature.
Voltage too low.
Incorrect or insufficient lubrication.
Inefficient electrovalve.
Tripping of the thermal cutout of
the motor.
Electric fault.
One of the phases of the 3-phase
power supply is missing due
probably to blowing of a fuse.
Too much oil inside the unit.
Wear on segments.
Presence of dirt/grit inside the
cock.
