• quiet and efficient scroll compressor technology

FEATURES/BENEFITS

All in one package — high cooling efficiency, installation con-

venience, ease of accessibility for time-saving maintenance.

SPACE AND COST-SAVING DESIGN —

Model 502A is spe-

cifically designed to provide the building owner with behind the

scenes cooling, because it installs inside the ceiling. That’s

why we call it the Bryant Ceiling

PAC

unit. The compact design

and low silhouette enable it to fit easily and securely above the

conditioned space. Single package construction makes it easy

to install with minimal time and cost.

APPLICATION FLEXIBILITY —

If desired for particular appli-

cations, the unit can also be installed as a split system with the

condenser section mounted horizontally. Centrifugal fans per-

mit ducting of both evaporator and condenser air.

QUIET OPERATION —

Commercial end users appreciate the

extra comfort of quiet operation. Bryant engineers met the

challenge by specifying heavy insulation, vibration-resistant

construction and operating components that function at low

noise levels, all of which keep system sound at a minimum

level.

EASY MAINTENANCE —

When it comes to maintenance, the

502A unit rates high in accessibility. Indoor location is ideal for

the maintenance technician, and five access panels, easily

removed, provide quick and convenient access to all compo-

nents when needed. As an added plus, all required service/

maintenance access can be from one side allowing the unit to

be located against a wall or ceiling plenum obstruction, an

obvious space-saving idea.

BRYANT QUALITY AND RELIABILITY —

The Bryant 502A

Ceiling

PA C

units have much to offer the cost- and efficiency-

conscious commercial owner. Every unit is thoroughly run

tested at the factory and equipped with safety controls

designed to monitor and protect over the life of the unit.

SCROLL COMPRESSOR TECHNOLOGY —

Scroll compres-

sors are designed for high efficiency and are internally spring

mounted to minimize vibration noise. Each compressor is

hermetically sealed against contamination to promote longer

life and dependable operation. Scroll compressors are

standard on all units.
