INTRODUCTION

Prior to initial start-up of the 19XR 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 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.
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 dis-
sipate body electrostatic charge before working inside con-
trol center.
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 com-
munications. It has been tested and found to comply with
the limits for a Class A computing device pursuant to Inter-
national Standard in North America EN 61000-2/3 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.
CAUTION
Do NOT punch holes or drill into the top surface of the
VFD (variable frequency drive) enclosure for field wiring.
Knockouts are provided on the side of the VFD enclosure
for field wiring connections. The top panel of the enclosure
must be removable for servicing the power module.

PROVIDE MACHINE PROTECTION. Store machine
and starter indoors, protected from construction dirt and
moisture. Inspect under shipping tarps, bags or crates to be
sure water has not collected during transit. Keep protective
shipping covers in place until machine is ready for
installation.
WHEN FLUSHING THE WATER SYSTEMS isolate the
chiller from the water circuits to prevent damage to the heat
exchanger tubes.

CHILLER FAMILIARIZATION (FIG. 1-3)

Chiller Information Nameplate -

nameplate is located on the right side of the chiller control
panel.

System Components -

cooler and condenser heat exchangers in separate vessels,
motor-compressor, lubrication package, control panel, econo-
mizer (optional) and motor starter. All connections from pres-
sure vessels have external threads to enable each component to
be pressure tested with a threaded pipe cap during factory as-
sembly.
