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 19XR unit is located
on the back of the CVC/ICVC.
CHILLER FAMILIARIZATION
(Fig. 1 and 2)
Chiller Information Nameplate —
The information
nameplate is located on the right side of the chiller control
panel.
System Components —
The components include the
cooler and condenser heat exchangers in separate vessels,
motor-compressor, lubrication package, control panel, and mo-
tor starter. All connections from pressure vessels have external
threads to enable each component to be pressure tested with a
threaded pipe cap during factory assembly.
Cooler —
This vessel (also known as the evaporator) is lo-
cated underneath the compressor. The cooler is maintained at
lower temperature/pressure so evaporating refrigerant can re-
move heat from water flowing through its internal tubes.
Condenser —
The condenser operates at a higher
temperature/pressure than the cooler and has water flowing
through its internal tubes in order to remove heat from the
refrigerant.
Motor-Compressor —
This component maintains sys-
tem temperature and pressure differences and moves the heat-
carrying refrigerant from the cooler to the condenser.
Control Panel —
The control panel is the user interface
for controlling the chiller. It regulates the chiller’s capacity as
required to maintain proper leaving chilled water temperature.
The control panel:
• registers cooler, condenser, and lubricating system
pressures
• shows chiller operating condition and alarm shutdown
conditions
• records the total chiller operating hours
• sequences chiller start, stop, and recycle under micropro-
cessor control
• displays status of motor starter
• provides access to other CCN (Carrier Comfort Net-
work) devices and energy management systems
• Languages pre-installed at factory include: English, Chi-
nese, Japanese, and Korean (ICVC only).
• International language translator (ILT) is available for
conversion of extended ASCII characters (ICVC only).
