6. STARTUP OPERATION [Startup Operation of the Air Compressor]
Press the UNLOAD STOP button to stop the air
compressor. Operation stops when the air end and
the air piping have dried for 5 minutes. To stop the
compressor immediately without unloading, press
the STOP button.
Check the LCD for pressures, and verify that:
Oil pressure, interstage air pressure, 0 psi (0 MPa)
or 1 psi (0.01 MPa) depending on your operating
conditions).
Check the condensate drain discharge from the
control line filter by checking the sight glass on the
control line filter. (Fixed speed type)
Close the stop valve.
Open the water drain valve. Do not fail to drain the
cooling water specifically winter season because the
remaining water may be frozen inside and as a result
the casing and/or coolers may be burst.
