TWINSTAR 450 and TWINSTAR 690:
Connect the compressor to the power supply.
Extension cables should have a cross section minimum 2.5 mm2 and can have length maximum
30 m.
Turn the pressure reducer (2) by turning it counterclockwise.
Switch on the compressor using the switch (1) to start it.
At the compressor 690 TWINSTAR check the direction of rotation, as described on the page above.
Let the compressor run for approximately 10 minutes without load.
In this case check the following points:
If pressure rises in the air receiver? You can see it on manometer (3)
−
If the compressor switches off automatically by achievement of maximum pressure? (see technical
−
specifications, starting from page 7)
Maximum allowable operating pressure produced by the compressor is limited automatically by the pressure
relay. Safety valve limits additionally the pressure rise above 10% of maximum allowable.
WARNING
Explosion risk by excess of the maximum allowable operating pressure.
When pressure is restored and the compressor is switched off by achievement of maximum pressure (see
technical specifications, starting from page 7), the compressor is ready for operation.
Switch off the compressor using the switch (1).
Release condensate as described on page 32.
ATTENTION!
Condensate is a harmful substance that is hazardous to environment.
Place an appropriate container under drainage hole.
Spilled condensate to be immobilized by using a binder.
Immobilized condensate remove with a rag.
Utilize a rag in accordance with applicable legal requirements of the application place.
Never make any actions with the safety valve.
