If required, the orientation may be changed to +90° or -90° from default ‘in-
line-with-duct’.
Ensure power to actuator is removed and allow actuator to travel to end
position.
Unscrew the 8mm AF head screw (central motor retaining screw) and
remove the set-point assembly
.
Remove the 10mm AF head screws (motor body retaining bolts). (It may be
necessary to partially wind the actuator a few degrees with the aid of the
manual reset key to release residual torque).
Remove the actuator and refit in new position w
wiitthhoouutt changing the blade’s
position.
Secure with the 10mm AF head screws (5Nm), followed by the ’
set point
assembly’ and 8mm AF head screw (3Nm).
Test (refer to section 1

Dampers are supplied with actuators set to travel to ‘fully open’ position by
default.
Optionally, dampers can be set so that the ‘open position’ is restricted to
between 30° to 90° (60° range). This is for system air balancing purposes,
should it be required.
To utilise set-point positioning, temporarily release actuator
(using 2.5mm AF
allen key),
unscrew and reposition the positional limiter engaging into the
2mm dia holes (as below).

Make the following connections to achieve damper status indication:
Closed - use 1&2
open when not fully open - use 4&6
