INTRODUCTION
Prior to initial start-up of the 23XRV chiller, those involved
in the start-up, operation, and maintenance should be thoroughly
familiar with these instructions and other necessary job data.
This book is outlined to familiarize those involved in the start-
up, operation and maintenance of the unit with the control sys-
tem before performing start-up procedures. Procedures in this
manual are arranged in the sequence required for proper chiller
start-up and operation.
ABBREVIATIONS AND EXPLANATIONS
Frequently used abbreviations in this manual include:
Words printed in all capital letters or in italics may be
viewed on the International Chiller Visual Controller (ICVC)
(e.g., LOCAL, CCN, ALARM, etc.).
Words printed in both all capital letters and italics can also
be viewed on the ICVC and are parameters (e.g., CONTROL
MODE, COMPRESSOR START RELAY, etc.) with associated
values (e.g., modes, temperatures, percentages, pressures, on,
off, etc.).
Words printed in all capital letters and in a box represent
softkeys on the ICVC control center (e.g., , ,
, , etc.).
Factory-installed additional components are referred to as
options in this manual; factory-supplied but field-installed ad-
ditional components are referred to as accessories.
The chiller software part number of the 23XRV unit is lo-
cated on the back of the ICVC.
23XRV CHILLER FAMILIARIZATION
(Fig. 1, 2, and 3)
Chiller Identification Nameplate —
The chiller
identification nameplate is located on the right side of the
chiller control center.
System Components — The components include
cooler and condenser, heat exchangers in separate vessels,
motor-compressor, lubrication system, control center, and
optional economizer. All connections from pressure vessels
have threads, flanges, or victaulic grooves to enable each com-
ponent to be pressure tested during factory assembly.
WARNING
This unit uses a microprocessor control system. Do not
short or jumper between terminations on circuit boards or
modules. Control or board failure may result.
Be aware of electrostatic discharge (static electricity) when
handling or making contact with circuit boards or module
connections. Always touch a chassis (grounded) part to dis-
sipate body electrostatic charge before working inside con-
trol center.
Use extreme care when handling tools near circuit boards
and when connecting or disconnecting terminal plugs. Cir-
cuit boards can be damaged easily. Always hold boards by
the edges, and avoid touching components and connections.
This equipment uses, and can radiate, radio frequency
energy. If not installed and used in accordance with the
instruction manual, it may interfere with radio communica-
tions. This equipment has been tested and found to comply
with the limits for a Class A computing device pursuant to
Subpart J of Part 15 of FCC Rules, which are designed to
provide reasonable protection against such interference
when operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause inter-
ference, in which case the user, at his own expense, will be
required to take whatever measures may be required to cor-
rect the interference.
Always store and transport replacement or defective boards
in an anti-static shipping bag.
