Copyright 2010 Carrier Cor poration Form 50XCA-1PD The 50XCA single-pac kage cooling units with integ ral air-cooled condensers off er : • Compact, dur able , and attr active cabinet fits an y worki.
2 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.

30 Operating sequence All units require the addition of a ther mostat accessory package to complete the control circuit. The sequence of operation may vary depending on which package is selected. Room-mounted the rmostat — The unit uses an electronic ther mostat mounted in the conditioned space.
31 LEGEND NO TE S : 1. Wiring and piping shown are general points of connection guides only and are not intended for or to include al l details for a specific installation. 2. All wiring must comply with applicable local and national codes. 3. All piping must f ollow standard piping techn iques.
32 Location For best results unit must b e properly located and installed. Selected location should not be adjacent to an acoustically sensitive space, for example a co nference room or execu- tive office. The best location is in mechanical rooms near areas like elevators, restrooms, stairways, or similar spaces.
33 Setting condenser fan speed The 50XCA condenser has a centrifugal blower and a vari- able pitch drive which allow adjusting the condenser air flow to match the static from the louvers, ductwork, filters, and sound traps (if used). It is best to adjust the fan to the nominal air flow and th e rpm which will achieve this per for mance.
