Installation and commissioning

11.1 Checking the installation site

• Does the door leaf move easily over its entire swing range?
• Does the door leaf drop cleanly into the lock?
• Have all damping devices been removed (not simply reset)?
• Is the base on which the DFA 127 is to be mounted sufficiently stable? The
chassis must lie as flat as possible. Coarse unevenness must be cleared or
the bearing area must be made more powerful or be strengthened by means
of additional plates.

11.2 Positioning the DFA and arm

• Mark the drilling positions on the template according to the type of installa-
tion, the mounting plate and the arm
• Fix the template to the corresponding position
• Drill the boreholes. After the first borehole the chassis can be used as tem-
plate

11.3 Mechanical installation of the DFA

• Dismount the power supply and gear drive unit of the operator
• Fix the mounting plate, place the cables in position and mount any flexible
connections.

The casing must not be opened or disassembled due to the possibility
of injuries caused by spring tensions being suddenly released.
