Maintenance
Venting the oil separator tank:
1 Ball valve
A shut
B open
2 Pressure gauge
3 Hose coupling
 The pressure gauge on the oil separator tank must indicate zero psig.
Oil mist can escape when the oil separator tank is vented.
 Insert the nozzle (6) in the hose coupling (3) on the oil separator tank. The residual
pressure in the oil separator tank escapes.
 Remove the nozzle (6) from the hose coupling (3).
Venting the air aftercooler:
When the compressor package is vented, pressure is still present in
the air aftercooler and the pipework up to the minimum pressure check
valve. For this reason the compressor package must be isolated from
the compressed air system by closing the shut-- off valve between the
compressor package and the compressed air system. If isolation
shut-- off valve is not available, vent the compressed air system com-
pletely.
 Carefully remove the screw fitting (4, see chapter 9.13). The air aftercooler vents.
 Tighten the screw fitting again.
Close all maintenance doors and panels correctly before starting the
compressor package.
