COMPRESSOR OPERATION
The operation of the compressor is directly controlled by the pressure switch, which
immediately terminates the energy supply when the pressure in the tank reaches the
determined value and connects again, when the pressure reaches a value, 2 bar bellow the
maximum allowed pressure. That special function is set-up in the testing phase and is
predetermined by the client. All the electric motors are equipped with a safety system,
which terminates the energy supply in case of an excessive electric surge.
ATTENTION!
A proper compressor use means an exchange procedure of about 60%
of the active time;
The compressor has a safety valve integrated, which is set up to
pressure, higher of the maximum working pressure of the pressure
switch. It activates in case of a fault on the pressure switch and opens an
exhaust for excess air;
The client may never set the compressor up in any way to exceed the
pressure, stated on the pressure vessel;
In the operation time and a few minutes after stopping do not touch any
wires, connectors, compressor parts, valve or other parts, which may be
subjected to excessive heat and avoid burns;
Pressure in the compressor
The pressure is pre-set on a value, determined by the client when ordering. To change that
value, contact our service team.
Compressor maintenance
ATTENTION!
Before and during any intervention follow the safety instructions.
Disconnect the compressor from the power supply, before any interventions on
moving or rotating parts;
Before any intervention or disassembly of pneumatic parts empty the pressure tank
and void the pressure of the inner pneumatic circle with the exhaust valve.
Carefully unscrew the exhaust valve to release the air out of the system slowly. Check
if there is any air left in the pneumatic circle with the help of the manometer.
