Limits of use of the 422 in relation to wind
The tables indicate the maximum permitted wind force for the 422 with maximum force regulation (by-pass) in relation to the:
-
Surface of the leaf exposed to the wind
-
Length of the leaf
-
Standard or short length rod (PED.)
-
Pump flow rate
Winds stronger than those permitted could affect the operation of the 422.
It is the responsibility of the installer to assess the impact of the wind on all components of the structure (columns, hinges, leaves) in order
to calculate the maximum permitted wind force for the automation.
