. If different regulations apply for your region, you are obligated to follow t ese.
T e AWS as to be operated outdoors or in a room wit sufficient ventilation, because t e
equipment emits a ig amount of eat w en turned on. T e working space needs proper
openings for cooling.
If a proper air supply cannot be guaranteed wit windows or ot er openings, ventilators are
required for forced ventilation. T e ventilators need to guarantee a 15-20% greater amount
of cooling air t at is needed for perfect cooling of all t e compressors.
ATTENTION!
The ventilation openings have to be set up in a way to avoid the intake of
dust, lacquer, gasses or other explosive mixtures. Do not set the
equipment up in a dusty place or close to gas drains. The AWS is designed to
work at temperature from -15 to +45 °C. If the equipment is subjected to
temperatures out of this rank, damage may occur on the aggregate.

Picture 6: pressure switch
ATTENTION!
To improve the start-up of the compressor, a pressure switch is added,
with a release valve. The valve stays open until the inner pressure does
not reach about 1 bar. At this value the valve closes. This enables the motor to
immediately reach normal rotations and guarantees an optimal start-up even in
cold weather or tensions under the normal level.
To turn off t e compressor, always use t e button on t e pressure switc . If you pull out t e
plug, t e compressor ead will not release pressure, w ic mig t cause problems at t e next
start-up of t e equipment. T e compressor is ot erwise meant to work under low
temperatures, alt oug in suc cases it is required to monitor possible freezing of t e
condensate in t e system.
Compressor information
Wit eac contact wit t e manufacturer (ordering spare parts, service…) use t e
information, provided by t e label, attac ed to t e front site of t e documentation and t e
bottom of t e compressor aggregate. All ot er information about t e compressor you can
get in t is manual.

COMPRESSOR OPERATION
T e operation of t e compressor is directly controlled by t e pressure switc , w ic
immediately terminates t e energy supply w en t e pressure in t e tank reac es t e
determined value and connects again, w en t e pressure reac es a value, 2 bar bellow t e
maximum allowed pressure. T at special function is set-up in t e testing p ase and is
predetermined by t e client. All t e electric motors are equipped wit a safety system,
w ic terminates t e energy supply in case of an excessive electric surge.
ATTENTION!
A proper compressor use means an exchange procedure of about 60%
of the active time;
The compressor has a safety valve integrated, which is set up to
pressure, higher of the maximum working pressure of the pressure
switch. It activates in case of a fault on the pressure switch and opens an
exhaust for excess air;
The client may never set the compressor up in any way to exceed the
pressure, stated on the pressure vessel;
In the operation time and a few minutes after stopping do not touch any
wires, connectors, compressor parts, valve or other parts, which may be
subjected to excessive heat and avoid burns;
Pressure in the compressor
T e pressure is pre-set on a value, determined by t e client w en ordering. To c ange t at
value, contact our service team.
Compressor maintenance
ATTENTION!
Before and during any intervention follow the safety instructions.
Disconnect t e compressor from t e power supply, before any interventions on
moving or rotating parts;
Before any intervention or disassembly of pneumatic parts empty t e pressure tank
and void t e pressure of t e inner pneumatic circle wit t e ex aust valve.
Carefully unscrew t e ex aust valve to release t e air out of t e system slowly. C eck
