INITIAL START-UP CHECKLIST FOR

19XRV HERMETIC CENTRIFUGAL

LIQUID CHILLER . . . . . . . . . . . . . . . . . . . .CL-1 to CL-12

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.).

CAUTION

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.
