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

•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.

•Units are built in an ISO 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.

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.
