Air leakage from the valve under the pressure switch:
This could be caused by imperfect tightness of the check
valve.
(4).
Discharge all pressure from the tank.
Unscrew the hexagonal head of the valve and thorough-
ly clean both the element and its seat. Reassemble the
valve.
Air leaks:
These can be caused by poor tightness of a union.
Check all the unions, wetting them with soapy water.
The compressor runs but does not load:
This may be due to failure of the valves or a seal. Contact
a service centre.
If the compressor has difficulty starting up, check the
following:
Does the mains power match the power on the data
plate. Are power cable extensions of adequate diameter
or length?
Is the work environment too cold? (under 0°C)
Has the motor protection tripped? (see 2.4).
Is the electrical line powered and is the system is correct-
ly dimensioned?
If the compressor does not stop when maximum
pressure is reached, the tank safety valve will enter into
operation.
In this case, you must contact your nearest authorised
service centre to arrange a check.
5.1 TECHNICAL DATA
• Refer to the label on the compressor.
• For the European market, the compressor tanks are
manufactured to meet Directives CE 2006/42 e CE
2009/105 (tank).
• The sound pressure level measured in a free range at
a distance of 1 m ±3dB(A) at the maximum operating
pressure.
• The sound level value can increase from 1 to 10 dB(A)
depending on the environment in which the compres-
sor is installed.
5.2 STORING THE PACKED AND
UNPACKED COMPRESSOR
For as long as the compressor remains idle before
unpacking, store it in a dry place with a temperature
b 5°C and + 45°C and sheltered against the
weather.
For as long as the compressor remains idle after unpack-
ing, waiting for commissioning or due to production
stoppages, protect it with tarpaulins to prevent dust
from settling on the mechanisms.
If the compressor is idle for long periods of time, the oil
must be replaced and the operational efficiency of the
compressor needs to be checked.
5.3 PNEUMATIC CONNECTIONS
Make sure to always use pneumatic tubes for com-
pressed air with maximum pressure characteristics that
are adequate for the compressor.
Never attempt to repair faulty tubes.
