Hi,
I have one chiller FOCS2/K 3902 with Bitzer compressors CSH2583 and one of compressors have - only for 1 second , un metallic sound when it stops normal.
All is OK with pressure , temperature , noises when compressor run .

I hope that this noise does not indicate a faulty compressor early.
If you've encountered the phenomenon , please , help me with information.

Many thanks
