800 ton Carrier 19XR starting up 

Rush Daamir critical situation? There was nothing wrong with the chiller, I just filmed the startup one morning.

@@brendana4695 dear I mean during maintenance time, need to know the critical points to its cure.

Contact Carrier for the service manual. This machine had a 10 year tear down right before I took this video. The video is from 2011 and I don’t work there anymore. Chiller was installed in 1999.

yes it is

I've got a wye delta but I want to convert it to a benshaw.

I find the XR series to be the easiest to work on. Older Carrier's can be a challenge. Trane's are nice but have their own set of issues, Yorks are alright but I don't like the open drive.
