INTRODUCTION
Prior to initial start-up of the 19XRV unit, 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 con-
trol system 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, ICE BUILD
OPTION, etc.) with associated values (e.g., modes, tempera-
tures, percentages, pressures, on, off, etc.).
Words printed in all capital letters and in a box represent
softkeys on the ICVC control panel (e.g., , ,
, , etc.).
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
dissipate body electrostatic charge before working inside
the VFD enclosure.
Use extreme care when handling tools near boards and
when connecting or disconnecting terminal plugs. Circuit
boards can easily be damaged. 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 cause interference to radio
communications. It 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
interference, in which case the user, at his own expense,
will be required to take whatever measures may be
required to correct the interference.
Always store and transport replacement or defective boards
in anti-static shipping bag.
