FactolT-installed additional components tue refen_ed to as
options in this manual; factou-supplied but field-installed
additional components are referred to as accessories.
The chiller software pall number of the 19XRV unit is
located on the back of the 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,
compressor-motor, lubrication package, control panel, and
motor sttutel: All connections fiom pressure vessels have exter-
nal threads to enable each component to be plessure tested with
a thleaded pipe cap during factory assembly.
Cooler-
This vessel (also known as the evaporator) is
located underneath the compressol: The cooler is maintained at
lower temperature/pressme so evaporating refrigerant can
remove heat fiom 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 fi_)m the
refrigerant.
Motor-Compressor-
This component mainttfins 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
lequiled 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
Network) devices and energy management systems
• Languages pre-installed at factory include: English,
Chinese, Japanese, and Korean.
• International language translator (ILT) is available for
conversion of extended ASCII characters.
Variable Frequency Drive (VFD) -- The VFD al-
lows
for the proper st_ut and disconnect of electrical energy for
the compressor-motor, oil pump, oil heater, and control panel.
Storage Vessel (Optional)--There
are 2 sizes of
storage vessels available. The vessels have double relief valves,
a magnetically-coupled dial-type refrigerant level gage, a
one-inch FPT drain valve, and a l/2-in, male flare vapor con-
nection for the pumpout unit.
NOTE: If a storage vessel is not used at the jobsite, factory-
installed isolation valves on the chiller may be used to isolate
the chiller charge in either the cooler or condenser. An optional
pumpout system is used to transfer refrigerant from vessel to
vessel.
