Features/Benefits (cont)
The compact footprint and service
from the front of the units save valu-
able floor space in equipment rooms.
Belt drive condensers provide adequate
static to overcome ducting and louver
static losses. This allows units to be po-
sitioned against an existing window or
wall louver, or ducted to the outside, as
required. These units can be installed
in the equipment room or the condi-
tioned space and used for either ducted
or free return applications. Unit supply
air discharge is vertical.
Easy installation and
maintenance
The units are completely pre-piped
and wired at the factory to ensure time
and money saving installation and ser-
vice. Exterior access panels are easily
removed to provide speedy inspection,
and service work may be done from
the front of the unit. Precision engi-
neered parts translate to a quality built,
reliable design that will operate effi-
ciently, minimize service calls, and pro-
vide years of reliable operation.
Designed for customer
satisfaction
Where space and styling are important
considerations, 50XCA units are de-
signed to exceed expectations. The
high quality baked enamel finish will fit
any environment attractively. These
packaged systems provide the user
with economy and product satisfaction
in cooling, dehumidification, filtering,
and air circulation.
Efficient design to increase
savings
In order to provide an energy efficient
HVAC solution, all 50XCA units have
been designed to exceed the ASHRAE
90.1 (2010) guidelines.
Special features for outstand-
ing performance
• High-efficiency scroll compressors
deliver quiet, reliable cooling capac-
ity. Compressor motor protection is
assured by quick-acting, internal
sensing elements that prevent trou-
ble before it starts.

• Space-saver slab type evaporator
and condenser coils use advanced
heat transfer technology and pro-
vide peak heat transfer efficiency
with large coil face area. Fins are
mechanically bonded to nonfer-
rous, seamless tubing for efficient
leak-free operation.
• Quiet fan performance moves large
volumes of indoor air. Compact
housing and specially designed dis-
charge air section provide superior
air-handling capacity.
• Convenient front access electrical
control center contains all factory
pre-wired control devices.
• A stainless steel, sloped, condensate
pan is standard. As a result of this
new design, the coil is easily
accessed for cleaning.
• The cabinets are constructed of gal-
vanized steel, bonderized, and
coated on all external surfaces with
a baked enamel finish. The paint
finish is nonchalking and is capable
of withstanding ASTM (American
Society for Testing and Materials)
Standard No. B117 500-hour salt
spray test.
• Choose between a full line of room-
mounted thermostats.
• Full compressor protection is
assured by several devices, including
current-sensing lockout relay(s), anti-
short cycle control, and high and
low-pressurestats. These devices
lock out the compressor(s) under
abnormal operating conditions to
prevent compressor damage and
ensure long life.

• The 50XCA units are covered by a
standard limited 5-year warranty on
the compressor and a standard lim-
ited one-year warranty on all other
parts.
• Easy to understand and operate
controls provide a virtually mistake-
proof control operation.
• All motors are protected against
single-phasing conditions.

9001:2000 (International Standards
Organization) certified manufactur-
ing facility, and are fully run-tested.
Environmentally sound
Carrier's Puron ® refrigerant (R-410A)
enables you to make an environmen-
tally responsible decision. Puron
refrigerant (R-410A) is an HFC refrig-
erant that does not contain chlorine
that is damaging to the stratospheric
ozone layer. Puron refrigerant
(R-410A) is unaffected by the Montreal
Protocol. Puron refrigerant (R-410A) is
a safe, efficient and environmentally
sound refrigerant for the
future.
