In the test mode, e.g. with batteries (insert the fuse!), avoid connecting the
actuator to the control panel at the same time. Ignoring this instruction may result
in damaging the power outlet of the control panel.
•
Remember to ensure free movement of the actuator for the entire feed range. The
actuator shall not meet any solid obstacles on its way.
•
The distance between the actuator pivoting point and the eye bolt hole is equal to
100 mm and may be adjusted within the range from 92 mm to 105 mm by
unscrewing the eye bolt.
Non-compliance with the recommendations given above, as well as opening or any
attempts to open the housing, will result in voiding the warranty.

5.1.9. PNEUMATIC SYSTEM
The gas pressure in the system after emergency release, may exceed 30 bar. For
that reason it is very important to make the installation connecting individual elements of
the pneumatic system very carefully. It is recommended to make this installation of certified
elements for this level of pressure: Ø6/4 copper tubes, 10000 series screw connectors.
Screw joints should be sealed with a Teflon tape or Loctite 243 glue for bolts. To protect
actuator fixing screws against loosening caused by vibrations, also use Loctite 243 glue.
