AC Diagnostic System:server room Filter Size(s) daikin mini split filters Returned tstat to original settings: Y Unit operational; prior to leaving: Y Notes: Upon arrival,checked in with Rich and he directed me to the server room. Located mini split unit. And found float switch had shut system off and was actually stuck on the top not letting system come back on. Got the float un stuck and filled with water. Pump came on but was not pumping water past the siphon. While putting system back together lower pump and shortened the length of tubing between pump and siphon and pump started to drain water normally and stopped. Once the float activation switch lowered again. Explained that if this is an ongoing issue, recommend installing larger capacity condensate pump to avoid further issues. Temperature split is currently 18.6 degrees between return and supply air. System is operational Before departure and also tested with water 3 times to make sure pump was actually draining water and
