Foreword
The central chiller consists of a refrigeration circuit to
provide cooling water to coolant.
This manual is to serve as a guide for installing,
operating, and maintaining the equipment. Improper
installation, operation, and maintenance can lead to
poor performance and/or equipment damage. Use
qualified installers and service technicians for all
installation and maintenance of this equipment.
This manual is for our standard product and is
general in nature. Unit-specific drawings and
supplemental documents are included with the
equipment as needed. Additional copies of
documents are available upon request.
Due to the ever-changing nature of applicable
codes, ordinances, and other local laws pertaining to
the use and operation of this equipment, we do not
reference them in this manual.
The equipment uses a hydrofluorocarbon (HFC),
trade named R-410A, as a chemical refrigerant for
heat transfer purposes. This chemical is sealed and
tested in a pressurized system containing ASME
coded vessels; however, a system failure will release
it. Refrigerant gas can cause toxic fumes if exposed
to fire. Place these units in a well-ventilated area,
especially if open flames are present. Failure to
follow these instructions could result in a hazardous
condition. We recommend the use of a refrigerant
management program to document the type and
quantity of refrigerant in the equipment. In addition,
we recommend only licensed and EPA certified
service technicians work on our refrigeration circuits.
