If dust goes inside, it may reach the air filter, causing rapid clogging
and part will be deposited over the components thereby preventing heat
exchange. It is therefore evident that the cleanliness of the in- stallation
location is extremely important for the proper operation of the machine, as
this will avoid excessive operation and maintenance costs.
To facilitate maintenance operations and create favorable air circulation compressor must have a good amount
of free space surrounding it (Min. 30 cm). The room should be equipped with openings towards the outside
placed in proximity of the floor and the ceiling, which will allow the natural circulation of the air. If this is not
possible, fans or extractors must be installed
It is not necessary to provide for special foundations or bases. The machine may be simply placed on a level
floor. Compressors fitted on fixed standing tanks should not be secured to the ground.
Climatic operating conditions:
• Temperature: from +5°C to +40°C
• Air relative humidity: max 70%
8. Pressure gauges installation
For safety reasons some models are provided with pressure gauges not installed. To correctly fix them on the
pressure regulator and the pressure switch, always use teflon material to avoid any air leak risk.
9. Electrical connection
The electrical supply line must stand the load indicated on the motor rating. Earthing must always be used for
installer safety.
Earth connection is necessary. Before connecting the compressor to the control
panel, a high sensitivity switch should be installed on the wall. Never connect the
earthing wire to the neutral pole.
If any electric cable or air hose is damaged it must be immediately replaced.
Electric cable may not contact hot parts of the compres- sor, insulation could
be damaged!
10. Compressor running
Connect the electric line by plug and the to the air line connecting it to the outlet placed on the filter (position
number 19 - see exploded view). Turn the switch of the pressure switch (18) in position "1".
Running of the compressor is fully automatic and controlled by the pres- sure switch, which stops it when
pressure in the tank (14) reaches a maximum value (approximately 7 bar), allowing compressor to start again
when it descends under a fixed pressure value (~5 bar). Read the receiver pressure value on pressure gauge
(21). When compressor receiver is under pressure, operator may regulate operating pressure acting on the
pressure regulator situated on the filter (19 – if present): to fix pressure required is necessary to rotate the hand-
grip regulator in clockwise direction to increase pressure, in counter clockwise direction to reduce it and read
the value on its pressure gauge (20). When delivery air pressure required is reached, push on the handgrip in
order to block it.
