Installation
CAUTION
•To prevent product damage, always disconnect
the power supply from the product before
performing installation and wiring.
IMPORTANT:
•Avoid application that keeps product operating
cycle excessively frequent.
•Meet the actuator rotating direction with the
damper rotating direction.
•Tighten the screws so that the actuator is securely
assembled with the damper.
•When installing this product, leave clearance for
maintenance as shown in Fig. 2.
Installation procedure: Min. 95 mm long shaft
Actuator with forward rotation (‘L’ side outward)
1) Mount the actuator with the ‘L’ side facing outward to the
damper shaft and temporarily tighten the hexagonal nuts
of the shaft clamp. Then, set the mounting position of
the universal bracket.

to min. 95 mm long shaft (1)
2) Insert the universal bracket into the slit of the actuator
and fix the bracket onto the damper with the two M4
tapping screws.

to min. 95 mm long shaft (2)
3) Confirm that the damper shaft is in fully closed position
and tighten the hexagonal nuts to completely fix the
actuator. Width across flats of the nuts is 10 mm.
Actuator with reverse rotation (‘R’ side outward)
1) Remove the C-clip from the shaft clamp and take out the
shaft clamp.

to min. 95 mm long shaft (1)
2) Turn over the actuator so that its ‘R’ side faces outward.
Refit the clamp in the actuator from the ‘R’ side, and then
attach the C-clip to fix the clamp.

3) Mount and fix the actuator to the shaft, referring to the
procedure of Actuator with forward rotation (‘L’ side
outward).
