If you mean refrigerant, I find that curious. If the pictures you sent were taken when the machine was at 88% FLA, it seems unusual to me that the evaporator small difference was 1.2*F. Usually the small difference temperature would be much greater in a low refrigerant charge situation.

Glad you solved your problem.

LMAO!!!!!!

When we took over this servicing site we then notice that something wrong with chillers it can't unload like as before! ( noticed by owner )! And I'm not very familiar with this York yk chiller that why I'm here in this forum.

Argument was most likey about energy management taking over control of pumps, causing the problems you are seeing now.

Or maybe I've been tainted by past experience with ems. :whistle:
