Closing torque
To comply with authority requirements or to
overcome over/under pressure the closing
torque can be adjusted.
The closing torque (spring force) is adjusted
by means of an Allen screw placed at the end
of the spring tube. The end plate has to be
dismantled. Turning the screw clockwise
increases the force. One turn equals a torque
change of approx. 1 Nm (0,75 lbf.ft). The door
must be in open position when the torque is
adjusted.
