washer is inside throat of valve.

Six-monthly
The fan impellor has been dynamically balanced and the fan assembly vibration
level should be in line with category BV-3, ISO 14694. An assessment of vibration
should be made every six months, or after a significant emission, or after any
misuse and a record kept of measured values. Excessive vibration levels should
be investigated and corrected immediately.
Vibration monitoring is mandatory on category 2G, 3G and 2D fan
assemblies.
