2.1.3 Temperature increase
The information listed in the following tables
corresponds to the heating of the side channel
housing and the air exiting compared to the
ambient temperature during operation with a
permissible total pressure difference and an air
pressure of 1013 mbar [14.7 psi]. At lower air
pressures these values increase.

Tightening torques for screw connections
The following values apply if no other data are
given.
With non−electrical connections, property classes
of 8.8 and 8 or higher as per DIN ISO 898 (DIN
EN 20898 / DIN ISO 898) are assumed.
