NOTES: 1. The oil pressure may exceed 0.18 MPa temporarily when starting the DSP . this is normal.
2. The discharge temperature varies from model to model. Refer the caution decal on the front panel of the unit for details.

① Check the LCD for operating pressures and tempera-
tures, and verify that:
– Discharge air pressure, interstage air pressure, oil
pressure, discharge air temperature, 2nd-stage suc-
tion air temperature, oil temperature stay within a
normal range; see the table below
② Make sure air containing drain from the inter cooler
drain discharge port and after cooler drain discharge
port is intermittently discharged.
WARNING
During inspection of the operation of the safety
relief valve, use the appropriate facial protec-
tion. High pressure air containing dust particles
can cause severe injury.

① P ress the UNLOAD STOP button. The compressor
then unloads for 5 minutes and then stops running.
(In the case of an emergency, press the STOP button.)
– STOP lamp on the add-on reactor starter panel glows for
reactor model.
② Check the LCD for pressures, and verify that:
– Oil pressure, interstage air pressure, 0 MPa (0 psi) (or 0.01
MPa (1 psi) depending on your operating conditions)
③ Check the condensate drain discharge from the con-
trol line filter by checking the sight glass on the con-
trol line filter.
④ Close the discharge stop valve.
⑤ Drain the cooling water.
Open the valve for draining water in the cooling water
piping and drain the cooling water.
To avoid damaging the casing and cooler, be careful
not to allow freezing during the winter.
