INITIAL START-UP CHECKLIST FOR
19XRV HERMETIC CENTRIFUGAL
LIQUID CHILLER .................... CL-I to CL-12
INTRODUCTION
Prior to initial start-up of the 19XRV unit, those involved in
the stall-up, operation, and maintenance should be thoroughly
familiar with these instructions and other necessary job data.
This book is outlined to fmnili;uize those involved in the
stmt-up, operation and maintenance of the unit with the control
system before performing stmt-up procedures. Procedures in
this manual ;ue arranged in the sequence required for proper
chiller start-up and operation.
This unit uses a microprocessor control system. Do not
shol_t or jumper between terminations on circuit bo;uds 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
control centel:
Use extreme c;ue when handling tools near bo;uds and
when connecting or disconnecting terminal plugs. Circuit
boards can easily be &_maged. 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 accor&mce with the
instruction manu;fl, 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 Pall 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 usel: 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.

Words printed in all capital lettel_ or in italics may be
viewed on the International Chiller Visual Controller (ICVC)
(e.g., LOCAL, CCN, ALARM, etc.).
W_rds printed in both all capital letters and italics can also
be viewed on the ICVC and are parmneters (e.g., CONTROL
MODE, COMPRESSOR START RELAY, ICE BUILD
OPTION, etc.) with associated values (e.g., modes, tempera-
tures, percentages, pressures, on, off. etc.).
W_rds printed in all capital lettel_ and in a box represent
softkeys on the ICVC control panel (e.g., _, _,
[INCREASE[, _, etc.).
