Calibration Of Safety Components - Swegon BlueBox Omega Sky Installation, Use And Maintenance Manual

7.3 Calibration of safety components

Any work on the unit must be carried out by qualified authorised personnel. Incorrect calibration values can
cause serious damage to the unit and harm people.
The control and safety equipment is calibrated and tested in the factory before the unit is shipped.
However, after the unit has been started, the safety devices must be checked (only the high and low pressure switches).
The checks must be carried out as described in the "Periodic checks" chapter.
