USE OF THE MACHINE
4.1.
Preliminary inspections
Before starting to use the compressor, a few
preliminary inspections are necessary:
-
install the suction filter on the compressor if this is not
installed;
-
instal the taps and the safety valve by simply screwing
them in their fittings;
-
check that the mains voltage is the same as shown on
the identification plate (fig. 1), its tolerance range is ±
5%;
-
if the compressor is not provided with an electrical plug,
connect a plug to the cable coming out from the
pressure switch. It must be suitable and proportionate
to the absorption of the motor as per tab. 2;
-
any prolongation of the feeding cable must be of a cross
section proportionate to its length for a max. length of
20 m. Please refer to tab. 2.
The electrocompressors must be connected to
a socket with a differential switch or a set of 3
delayed fuses AM (tab. 2).
4.2.
Starting and stopping the electrocompressor
Lower the pressure switch knob on "0" position (fig. 4),
insert the plug in the socket (fig. 5) and start the
compressor by lifting the pressure switch knob on "1"
position(fig. 4).
The first time a 3-phase compressor is switched on, check
its rotation direction by watching the arrow on the motor
cooling flywheel (fig. 6).
The fan works fully automatic: it is controlled by the
pressure switch which stops it when pressure inside the
tank has reached its max. level and starts it again when it
goes below its min. level.
During the first 5 working hours, check if the head screw
is will fixed.
To stop the electrocompressor, lower the pressure switch
knob on "0" position (off).

ADJUSTMENTS
5.1.
Adjusting the working pressure by the reducer
Unlock the reducer knob by pulling it upwards, adjust the
pressure at the desired value by turning the knob in a
clockwise direction to increase it and in a counterclockwise
direction to decrease it.
Once the optimal pressure has been reached, lock the
knob downwards (fig. 7).
6.
SAFETY GUARDS
The electrocompressor in its standard version is equipped
with all mechanical and electrical guards to safeguard the
operator's safety. In particular, it is fitted with a safety val-
ve which discharges the air in excess in the tank in case
of a non-authorised intervention on the pressure switch.
7.
MAINTENANCE
Before starting any maintenance or cleaning
operation, it is absolutely necessary to isolate the
machine from any source of energy. To do this,
set the pressure switch knob on "0" position and
unplug the machine.
7.1.
Descharging the condensate
Descharge the condensate from the tank at least once
per week by opening the exhaustion tap (fig. 8) below the
tank.
7.2.
Maintenance of the suction filter
Every 50 working hours, remove the suction filter and clean
the filtering element by blowing a jet of compressed air
from the contrary position (fig. 9 and 10). The filter must
be replaced every 500 working hours.
7.3.
Particular precautions
If the electrocompressor remains inactice for more than a
few days, empty the tank from its condensate. Do not
transport the tank under pressure.
