Mitsi electric vrf bc box noisey
Hi all,
I have been working on a site that has had 4 mitsi electric vrf systems recently installed, Friday evening on my last walk around the building, I can hear a high pitched noise coming from the bc boxes from different systems.
You can hear the gas moving around, coming from the bc box, then there's a high pitched noise for a couple of minutes, which disappears then returns.
Can anybody have a guess at the cause, or has anybody else come across the same thing.
Cheers in advance, Craig
