SAFETY CONSIDERATIONS

Installing, starting up, and servicing this equipment can be
hazardous due to system pressures, electrical components, and
equipment location. Only trained, qualified installers and service
mechanics should install, start up, and service this equipment.
When working on the equipment, observe precautions in the
literature, and on tags, stickers, and labels attached to the
equipment.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling, rigging, and setting bulky equipment.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all discon-
nect locations to alert others not to restore power until work
is completed.
IMPORTANT: This equipment generates, uses, and
can radiate radio frequency energy and if not installed
and used in accordance with these instructions may
cause radio interference. It has been tested and found
to comply with the limits of a Class A computing
device as defined by FCC (Federal Communications
Commission, U.S.A.) regulations, Subpart J of Part 15,
which are designed to provide reasonable protection
against such interference when operated in a commer-
cial environment.

INTRODUCTION

These instructions cover installation of 30XA080-500 air-
cooled liquid chillers with electronic controls and units with
factory-installed options (FIOPs). See Fig. 1.

INSTALLATION

If the unit is to be stored for a period of time be-

See below for the type of combination valve in 30XA units with the optional hydronic package. 30XA UNIT SIZE NOTE: Carrier recommends a differential pressure gage when measuring pressures across the pumps or balancing valves. This provides for greater accuracy and reduces error build-up that often occurs when subtracting pressures made by different gages.
