We were getting MFI trips on all units sporadically. However, one of our units was the worst offender. At one time it was tripping almost everyday and sometimes multiple times per day. Then we went about 2 weeks and had no trips. One thing we noticed. When the worst offender was tripping almost everyday the humidity was high and it rained nearly every day. During the two weeks that it didn’t trip it was hot and dry. Today we had rain and the worst offender tripped again to MFI duration exceeded. Has anyone made a correlation with MFI trips and humidity?
