Fault
The motor and/or the
compressor overheat
irregularly.
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
Insufficient ventilation.
Closing of air ducts.
Insufficient lubrication.
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.
Single-phase motors:
faulty capacitor.
3-phase motors:
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.

Remedy
Improve ambient conditions.
Check and if necessary clean the air filter.
Top up or change oil.
Release the compressor head by using
the pressure switch push button.
Improve ambient conditions.
Check that the mains voltage matches that
of the dataplate. Eliminate any extensions.
Check level, top up and if necessary
change the oil.
Call the Service Center.
Check level oil.
Single-stage, mono-phase versions:
operate on the button of the pressure
switch returning this to the OFF position
(par. 5.5.1).
Reset the thermal cutout (fig. 19) and
restart (par. 5.5.1).
If the fault persists, call the Service Center.
Versions with delta-star starter:
operate on the button of the thermal cutout
located inside the box of the electric panel
(fig. 20) and restart (fig. 2b).
If the fault persists, call the Service Center.
Other versions:
Operate on the button of the pressure
switch returning this to the OFF position
and then to ON again.
If the fault persists, call the Service Center.
Call the Service Center.
Have the capacitor replaced.
Check the fuses inside the electric panel
or the electric box and if necessary
replace those that have been damaged
(fig. 23).
Check oil level.
Call the Service Center.
Clean the cock.
