Information
This service manual is made to assist the service technician
apply his knowledge and 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
experienced 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.
