General Information
1-1 Introduction
This manual provides all necessary information for installation, operation and maintenance of
AEC/Application Engineering ACOA Series air-cooled water chillers.
To use this manual effectively, you must first determine your unit model number from the unit
nameplate. Since this manual is comprehensive for a wide variety of units, you should be careful
to use only those sections which apply to your model. Note that each section is clearly marked as
to the applicable models.
Your AEC/Application Engineering chiller has been manufactured under a careful quality
control system. If the package is installed, operated, and maintained with care and attention to
these instructions, your chiller should give many years of satisfactory service.
You should have a basic understanding of the principles of air conditioning, refrigeration, and
electrical controls for installing, operating, and maintaining this equipment.
