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%
Note: The reduction of air density in relation with altitude H is directly proportional to the reduction
of Outlet Air efficiency of the compressor.
Calculating formula for loss of efficiency (l/min) in relation with altitude:
Consider ρ_0=1,226 Kg⁄m^3
H [Km]= Operating altitude of the compressor
ρ_H [Kg⁄m^3 ]= Air density at altitude H
ρ_0 [Kg⁄m^3 ]= Air density at sea level

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 compressor, 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 pressure 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.
