QUIET, EFFICIENT OPERATION AND DEPENDABLE PERFORMANCE — Compressors have vibration isolators for quiet operation. Efficient fan and motor design permits operation at low sound levels. Unit sizes 090-180 offer lower utility costs through part-load operation using 2 stages of cooling. Quiet and efficient operation is provided by belt-driven indoor fans (standard on all units over 5 tons). The belt-driven indoor fan is equipped with variable-pitch pulleys which allow adjustment within the rpm ranges of the factory-supplied pulleys. Increased operating efficiency is achieved through computerdesigned coils featuring staggered internally enhanced copper tubes. Fins are ripple-edged for strength, lanced, and double waved for higher heat transfer.

The paint finish is non-chalking, and is capable of withstanding ASTM (American Society for Testing and Materials) B117 500-hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for the entire unit. In addition, all size 024-120 units are designed with a single, continuous top piece to eliminate any possible leaks. Totally enclosed outdoor-fan motors and permanently lubricated bearings provide additional unit dependability. Patented State-of-the-Art Chronotemp™ Defrost System uses time and temperature to keep the outdoor coil frost-free for economical, dependable operation. The Chronotemp defrost board can be easily configured for def...
