functioning properly and, if necessary, contact an Authorized Service Centre.
23. Spare Parts
Use only original spare parts which can be purchased from our distributors. Use of non original
spare parts voids the warranty and can lead to compressor malfunction. Repairs must be carried out
by an Authorized Service Centre.
24. Pneumatic Circuit
Use hoses, connections and pneumatic tools rated to handle pressures above the operating pressure.
25. Tank
Never unscrew any tank connections without first checking to ensure that the pressure has been
vented. Never make holes, welds or modifications on the tank.
26. Compressor Modifications
Never make any unauthorized modifications to the compressor. Such modifications can cause
damage and serious injury. Consult an Authorized Service Centre for any operations.
27. Using the Compressor for Painting
Never use the compressor in confined spaces or near open flames. Make certain that the work area
is adequately ventilated. In addition, wear a special mask to protect nose and mouth.

2.2 OPERATING PRINCIPLE
During the initial phase of start up, the electric motor ref. 29 (with "star" power supply),
rotates slowly. The solenoid valve ref. 4 is not powered and thus the suction valve ref. 1 it
controls remains closed. The length of this phase can be set.
During the second phase, the "delta" power supply accelerates the motor to reach the set
operating r.p.m. The solenoid valve ref. 4 is powered and the suction valve ref. 1 is opened,
thus allowing air to pass through the suction filter ref. 16 and enter the screw compressor
ref. 2. This starts the compression phase.
The air/oil mixture delivered by the screw compressor ref. 2 is conveyed into the air/oil
separator tank ref. 15.
An initial portion of the oil is separated from the air mechanically and deposits at the bottom
of the tank while the air collects at the top.
By force of pressure the air is forced to flow through the oil separator filter ref. 13 and, after
further separation of the oil, it is sent on to the low pressure valve ref. 9. This allows passage
of the air only after the pressure set point has been reached. When this happens, the air
passes through the air radiator ref. 8, where it is cooled, and then continues on to the
operating tank ref. 35.
The oil removed from the air inside the oil separator filter is sent, through the oil return from
separator line ref. 12, into the screw compressor. The amount of oil can be monitored
through oil recovery window ref. 22.
In the model with drier, the air passes through the drier before reaching the operating tank.
Unless the unit has an automatic drainage, the condensate accumulated inside the tank must
be eliminated manually through the condensate drainage ref. 36.
The pressure sends oil at the bottom of the tank to the thermostatic valve ref. 25. This valve
sends the oil with a temperature above the set point to the oil radiator ref. 7 where it is
cooled. Once cooled, the oil returns to the thermostatic valve, is mixed with hot oil coming
from the tank and is again checked by the thermostatic valve. Once the temperature set point
(low) is exceeded, the oil is sent to the oil filter ref. 17 and then into the screw compressor.
When the set maximum working pressure is reached, the pressure switch ref. 11 remove
power from the solenoid valve ref. 4 and trips the circuit. The suction valve ref. 1 closes air
flow and the compressor enters in "no-load" operating mode. This situation remains in force
until the system minimum pressure setting is reached.
If consumption is low or has stopped unit will continue operate in no-load mode for a set
amount of time and then reverts to stand-by mode. (see chapter 7).

5.1 CHARACTERISTICS AND STORAGE CONDITIONS
During periods of inactivity, before being unpacked (storage), the compressor must be kept at a
temperature of between +5 °C and +45 °C and in a dry place sheltered from the weather.
Once unpacked, when the unit is not going to be used (prior to start-up or when production is
interrupted), the compressor should be protected with a tarpaulin to protect dust from gathering on
the mechanical and electric mechanisms.
If the compressor has remained inactive for a long period of time, before starting it up again, change
the oil and check function.
5.2 TRANSPORT
To ensure that the unit is protected and does not incur shipping damages, the compressor is screwed
onto a wooden pallet and covered with a cardboard box.
All shipping information is printed on the compressor package (data and pictograms).
5.3 UNPACKING
When unpacking the unit, carefully check that the contents match what is indicated in the shipping
documents.
The user must dispose of packaging in compliance with current national regulations.
The machine must be unpacked by qualified personnel using suitable tools.

5.4 HANDLING
The compressor is to be lifted with a fork lift truck rated for the weight of the unit.
Check that the outside packaging is intact.
Unpack the machine carefully.
Check that the outside of the machine is intact.
Dispose of the packaging in compliance with current environmental regulations.
The compressor should be handled as indicated in figures 2

5.5 LOCATION
Install the compressor at the site point indicated at the time the order was placed. If the unit is
installed at a different site, the manufacturer cannot be held responsible for any ensuing
problems.
Unless specified otherwise at the time the order is placed, the compressor must run normally under
the environmental conditions indicated below.
The room where the compressor is installed must comply with current accident prevention
standards and must meet the following requirements:
Protected from rain and frost.
Relatively free of dust. In time, a dusty environment can lead to damage and operating problems.
Adequately ventilated and of such size that environmental temperature remains steady (min. 5°C,
max. 45°C) when the machine is running. At the maximum admissible environmental temperature
(45°C) and with a relative humidity above 80% machine performance can reduce. Likewise,
machine performance may be reduced when the unit is installed at an altitude of 1000 m above
sea level.
If hot air exhaust is inadequate, install exhaust fans at the highest position possible (see figure 4).
Lighting: the compressor is built considering current standards and seeking to reduce shadow
zones to the barest minimum, thus facilitating operator intervention; as the compressor room
lighting system is deemed important for personnel safety, there must not be any shadows, glaring
lights or stroboscopic effects due to the lighting.
Potentially explosive and/or flammable atmospheres: in its standard configuration, the compressor
is not designed to work in environments where there is the risk of explosion and/or fire;
5.6 FOUNDATIONS
Once the position for the compressor has been identified, check that it is set on a flat surface. The
machine does not require foundations or any specific preparation of the support surface
(foundation works).

CAUTION!!
Do not insert any check valves between the compressor and the tank.
The ducting must not exceed 3 metres in length; if this proves necessary, install
a fan on the outlet side (see figure 4).
The ducting must have a uniform section of 0.3 m².
Condensation must not be discharged into the environment or into the sewers.
The well must be fit with a valve and removable container, or it must be
connected to a special unit to separate the air from the water.
