Hello guys. I'm an HVAC service tech whose been assigned 2 buildings with 1 RTAA and 1 RTAC Trane chiller for each building. I've only been doing commercial work for 2 years, so I'd like to get as much documentation on these as possible to help me get familiar with the way they work and to also help with repairs/maintaining them. Our guy who used to take care of them is leaving soon and is limited with what he can show me due to time.

The specific model for one building would be:

RTAA2004XT010AODO
and
RTAC2004UQONUAFNN

That's the info I have so far. Also, are wiring diagrams for these machines available online?
