I know this is going to be dumped in my lap next week so I thought I would get a head start.
I checked out a building that has been closed for 2 years and what it would take to re-open.
This building has the old Trane Classroom Unit Ventilators M/N-FDSN-12A
On a Trane small Chiller M/N-CGAEC60 1996
All the bearings are shot on all 20 Unit Ventilators. Most motors are unplugged.
Anyone ever rebuild these? and if so how had are they. Can it be done without touching the coil? Thanks
