training to this model air conditioner. This manual is written both for experienced service
persons and those who are new to air conditioning service. To help those with less
experience or who are new to this kind of unit we have included more explanations of
basic procedures in simple language than is usual in some service manuals. The experi-
enced technician will of course find he knows many of these things already and can go
directly to the procedures and information he needs; the less experienced technician will
better understand what to do even before he arrives on the job, and therefore be better
able to work by himself as well as assist the more experienced technician.
