Hi,
I’ve been reading the forum for a long time and I've learned a lot: thank you! This is my first post.
I’ve just had installed a 3x1 FUJITSU mult-split system: two 3,5Kw units, and one 2,5Kw unit. Split 1 (3,5Kw) is about 70 cm from the compressor, and splits 2 and 3 are about 7 m each one. Vacuum and leak tightness nitrogen tests were completed (in that order).
The thing is that split 1 makes a noise, and I’m not sure if it’s normal. It doesn’t seem to be the typical plastic “chirp”, but instead it’s like a conduit noise or like circulating fluids (gas?). Just one split makes the noise, the one closer to the compressor. On the other hand, it seems to work fine. The noise appears at the beginning, then goes on cyclically, and it can also be perceived at the end, even when the electric current is switched off.
I hope the noise can be heard in the video:

It appears at second 50’’: then the expelled air hides it more or less. When the split is turned off, after minute 3, it keeps on and is still clearly audible. Is it normal? If not, what it could be the reason?
Any advice would be gratefully received.
Thanks!
