Carrier 19 Series - Manual (Page 7)

Engineering excellence provides lower first
costs and years of trouble-free service
Single unit construction
Carrier centrifugals are the most com­
pletely packaged units of their kind.
Chiller is shipped as a single unit com­
plete with integral storage tanks where
required. Ready for quick connection
to water and electrical sources at the
job site. (Compressor is field installed
on the 1,600-2,000 ton (5627-7034 kW)
models; the heat exchanger and
economizer are factory assembled.) In
addition. Carrier centrifugals arrive at
the job site with controls mounted and
pre-wired including the chilled water
thermistor. All control connections can
be made to a single terminal strip. Single
unit construction assures minimum in­
stallation time, minimum installation
costs.
Factory-wired oil pump starter
Models available for U.L. listing feature
a factory-wired oil pump starter The
starter is factory wired to the machine
with overloads and contactors sized by
Carrier for U.L. compliance. The entire
assembly is factory mounted to save in­
stallation time and field labor costs.
Permanent shipping bases
Rigging can be done faster and the need
for costly concrete bases and supports
is eliminated with 19 Series permanent
shipping bases.
Prepiped motor lubrication
package
The oil pump, motor, filter, cooler,
pressure controls, and electrical ter­
minals are all prepiped and wired to
save on-site labor costs and installation
headaches.
Storage tank
The storage tank is an integral part of
the machine design on all R-12 and
R-500 units. No additional pipings,
fittings or valves are needed. No in­
creased floor space is required which
saves you first cost dollars. Servicing or
testing may be easily accomplished
without time-consuming transfer to
separate containers which saves you
service dollars. Models using R-114
offer the storage tank as an option at
minimal cost. They are constructed to
ASME code requirements and include
all necessary connections for refrig­
erant transfer system.
Factory start-up
Carrier start-up service for your ma­
chine is included in the purchase price.
This assures you of trouble-free, work­
ing installation right from the start. It
includes refrigerant transfer, leak test­
ing and precision calibrating of the solid
state control settings and safety control
settings.
Integral chilled-water sensor
A chilled-water thermistor probe is fur­
nished, installed in the leaving chilled
water nozzle as part of the machine’s
standard control system. A signal from
the sensitive solid-state device to the
central control module automatically
initiates immediate adjustments to com­
pressor capacity. This eliminates the
need for accessory pneumatic equip­
ment, separate sensing devices, saves
you initial equipment cost, and makes
installation easier, more economical. As
part of the machine’s standard control
system, it does not have to be specified
in another portion of the job, and thus
further reduces first and installation
costs.
Elapsed-time indicator
Every Carrier centrifugal features an
elapsed-time indicator to provide an
immediate and constant record of
machine operating hours. No over- or
underestimating
when scheduling
maintenance. Mounted outside of the
control box for easy visibility.
Full line centrifugal
service centers assure
optimal care of your unit.
When you specify Carrier, you get a complete service
organization unequaled in the industry. Carrier Service
j Operations is a national organization in over 150 key loca­
tions throughout the United States and Canada. This is
the one service organization that has grown up with the
air conditioning industry. Today, more and more owners
rely on Carrier Service Operations for an in-depth, practical
approach to energy conservation. This extraordinary full­
time commitment to quality maintenance and service
proves Carrier’s interest in continued customer satis­
faction. Your centrifugal, in fact your entire HVAC system,
will be in the care of people who are fully versed on the
design, manufacture, installation, start-up and maintenance
of your equipment.
