QUIET, EFFICIENT OPERATION AND DEPENDABLE PER-
FORMANCE — 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 adjust-
ment within the rpm ranges of the factory-supplied pulleys.
Increased operating efficiency is achieved through computer-
designed coils featuring staggered internally enhanced copper
tubes. Fins are ripple-edged for strength, lanced, and double
waved for higher heat transfer.
