Replacing actuator

Troubleshooting:
• Fig. 1Voltage of screw terminals B must be
18V AC, fig. 1.
• Damper must be adjusted correctly, wide
open or shut.
Dismounting actuator
1. Disconnect the power to the dryer.
2. Loosen the Allen screws A. This releases the
damper shaft
Note! It is a 1/8" key, not mm key.
3. Dismount the 3 wires in the screw terminals
B (mark out the wiring positions).
4. Unscrew screw C.
The actuator can now be dismounted.
Mounting new actuator
1. Mount the screw C
2. Fig. 3 Turn the actuator as shown on.
3. Stick the end of the shaft through the hub at
the Allen screws A.
4. Fig. 3 Release the declutch lever and rotate
the hub until it is in the same position as
shown on.
5. Insert the range stop pin in position D
(supplied with the actuator). (Do not insert
the range stop pin D until the hub position
shown on fig. 3 has been reached). The
range stop pin is clipped into its final position
only after the pin passes through both
actuator plates. The range stop pin should
snap into position and not be removable
manually.
6. Tighten the Allen screws A into the damper
shaft with 5 Nm. It is possible to adjust the
damper opening by turning the manual
declutch lever
Note! When tightening the end of the shaft
the damper must be open.
