Note!

Ensure ease of movement!

►  Lightly grease thread of end plug.
►  Screw in end plug and tighten (tightening torque 280 Nm).
►  Check that all screw connections are tight.
►  If no other maintenance work is to be carried out: Restart the dryer (see

page 36).

Replacing solenoids of pilot control units Y1-Y5

The solenoids of the pilot control units are maintenance-free.

Proceed as follows to replace a defective solenoid:

► Depressurise the dryer and shut it down (see

page 35).

►  Disconnect plug from solenoid.
►  Undo nut holding solenoid.
►  Pull solenoid from end sleeve.
►  Fit new solenoid on to end sleeve.

Caution:

Make sure coil voltage is correct!

► Resecure solenoid with the nut.
► Hand-tighten nut.

Magnet

► Check that all screw connections are tight.
► If no other maintenance work is to be carried out: Restart the dryer (see

page 36).

Replacing needle valve (VN)

The regeneration gas volume indicates the amount of regeneration gas that flows
through the tower to be regenerated.

The regeneration gas volume can be set with the needle valve in the check valve
block. The manufacturer presets the regeneration gas volume at the factory to
the specified operating data. The set value is specified on a label on the valve
block.

Follow the steps described in the following to replace the needle valve:

► Depressurise the dryer and shut it down (see page 35).

►  Remove the protective cap.
►  Release the lock nut on the needle valve.
►  Undo needle valve.
►  Screw in new needle valve.
►  Tighten lock nut.
►  Set the regeneration gas volume as described in the

next section.

► Check that all screw connections are tight.
► If no other maintenance work is to be carried out:

Restart the dryer (see page 36).
