9.3 Installation of heavy duty auto drain
1) Hold the hexagonal part (width across flats: 25) at the connection port (ball valve Rc1/2) of the air
dryer with a spanner and screw-in the barrel nipple and elbow in order.
2) Screw-in barrel nipple and heavy duty auto drain (width across flats of drain inlet port: 30)
completely. Mount the heavy duty auto drain vertically while facing the drain port downwards.
(Allowable inclination difference in the vertical direction is 5°)
3) For IDF60, mount male elbow (width across flats: 22) to the drain outlet port (width across flats:
27). For IDF70, IDF80 and IDF90 mount male connector (width across flats: 22) to the drain outlet
port (width across flats: 22) and mount the drain tube.
Note 1) Apply sealant tape or sealant to fit the long nipple.
Tightening torque: 28 to 30Nm
Note 2) If the amount of drainage flowing into the heavy duty auto drain is small, open the bleed valve
gradually to adjust so that the drainage can flow into the auto drain smoothly.
9.4 Maintenance
1) Check drain condition periodically (more than once a day). Then push flushing button to open exhaust
valve.
2) Pilot air is exhaust from the port indicated in the figure. Do not cover this exhaust port. Clean exhaust
port so that port is not blocked by dust, etc.
3) Close the ball valve before removing the heavy duty auto drain and open the bleed valve or push the
flushing button and confirm air pressure is released.
