1.0 GENERAL CHARACTERISTICS
The compressor units use single-stage screw rotary air compressors with oil injection.
The system is self-bearing and does not require bolts or other devices to anchor it to the floor.
The unit is completely assembled in the factory; the necessary connections for setting it up are:
connection to the power mains (see installation chapter)
connection to the compressed air network (see installation chapter)
2.0 INTENDED USE
The compressor has been built to supply compressed air for industrial use.
The machine cannot be used in premises where there is a risk of fire or explosion or where work is carried out which releases
substances into the environment which are dangerous with regard to safety (for example: solvents, inflammable vapours,
alcohol, etc.).
In particular the appliance cannot be used to produce air to be breathed by humans or used on direct contact with foodstuffs. These uses
are allowed if the compressed air produced is filtered by means of a suitable filtering system (Consult the manufacturer for these special
uses.) This appliance must be used only for the purpose for which it was specifically designed.
All other uses are to be considered incorrect and therefore unreasonable.
The Manufacturer cannot be held responsible for any damage resulting from improper, incorrect or unreasonable use.
3.0 OPERATION
3.1 OPERATION FOR COMPRESSOR
The electric motor and the compressor unit are coupled by means of a gear transmission.
The compressor unit takes in the outside air through the suction valve. The air taken in is filtered the cartridge fitted upstream from the
suction valve. Inside the compressor unit, the air and the lubricating oil are compressed and sent to the oil separating tank where the oil is
separated from the compressed air; the air is then filtered again by the oil separating cartridge to reduce the amount of suspended oil
particles to a minimum. At this point the two flows (of oil and air) are sent to two separate coolers where they are cooled, using a flow of air
taken from the environment by a special fan inside the machine.
The cooled oil returns to the circuit while the compressed air passes the using network.
3.2 OPERATION FOR DRYER
Dryer operation is described below. The gaseous refrigerant coming from the evaporator (4) is sucked by the refrigeration compressor (1)
and it is pumped into the condenser (2). This one allows its condensation, eventually with the help of the fan (3); the condensed refrigerant
passes through the dewatering filter (8) and it expands through the capillary tube (7) and goes back to the evaporator where it produces the
refrigerating effect. Due to the heat exchange with the compressed air which passes through the evaporator against the stream, the
refrigerant evaporates and goes back to the compressor for a new cycle. The circuit is equipped with a bypass system for the refrigerant;
this intervenes to adjust the available refrigerating capacity to the actual cooling load. This is achieved by injecting hot gas under the control
of the valve (9): this valve keeps constant the pressure of the refrigerant in the evaporator and therefore also the dew point never decreases
below 0 °C in order to prevent the condensate from freezing inside the evaporator.
The drier runs completely automatically; it is calibrated in the factory for a dew point of
5 °C and therefore no further calibrations are required.

4.0 GENERAL SAFETY STANDARDS
The appliance may be used only by specially trained and authorized personnel.
Any tampering with the machine or alterations not approved beforehand by the Manufacturer relieve the latter of responsibility for any
damage resulting from the above actions.
The removal of or tampering with the safety devices constitutes a violation of the European Standards on safety.
ENSURE THAT THERE ARE DISCONNECTOR SWITCH AND FUSES UPSTREAM THE MACHINE. FOR DETAILS (SIZE AND TYPE)

14.2 COMMAND AND CONTROL PANEL
BEFORE CARRYING OUT THE OPERATION TEST, READ CAREFULLY AND ACQUIRE A GOOD KNOWLEDGE OF THE
COMMAND FUNCTIONS.
14.3 Graphic controller for fixed compressor and Variable Speed Drive compressor.
Introduction
The electronic controller has following functions:
Controlling the compressor
Protecting the compressor
Monitoring components subject to service
Automatic restart after voltage failure (option)
Automatic control of the compressor
The controller maintains the net pressure between programmable limits by automatically loading and unloading the compressor in case of
fixed speed machines. For VSD machines the controller also change the motor speed in order to maintain the setpoint pressure. A number
of programmable settings, e.g. the unloading and loading pressures, the minimum stop time and the maximum number of motor starts are
taken into account.
The controller stops the compressor whenever possible to reduce the power consumption and restarts it automatically when the net
pressure decreases. If the expected unloading period is too short, the compressor is kept running to prevent too short stand-still periods.
Protecting the compressor
Shut-down
The compressor will be stopped and it will be indicated on the display in the following events:
compressor element outlet temperature bigger than the programmed shut-down level detected by temperature sensor
compressor element outlet temperature bigger than the programmed shut-down level detected by temperature switches
overload of the drive motor
overload of the fan motor
frequency converter failure (only for VSD compressors)
In chapter “Shut-down visualization” it’s explained how it appears on the display, how to recognize which is the shut-down and how to solve it.
Shut-down warning
A shut-down warning level is a programmable level below the shut-down level. If one of the measurements exceeds the programmed shut-
down warning level, this will also be indicated to warn the operator before the shut-down level is reached. The shut-down warning appears
in case of:
Too high temperature at the compressor element outlet
Too high or too low dew-point temperature for dryer equipped units
In chapter “Shut-down warning visualization” it’s explained how it appears on the display, how to recognize which is the warning and how to
solve it.
Service warning
If the service timer exceeds a programmed value, this will be indicated on the display to warn the operator to carry out some service actions.
Automatic restart after voltage failure
The controller has a built-in function to automatically restart the compressor when the voltage is restored after voltage failure.
