7-Condenser Fans B4 and B5
The specifications tables on pages 2-6 in this manual
shows the specifications of condenser fans used in
GCS16 series units. Condenser fans in all GCS16 units
(all voltages) use three-phase motors which do not require
a run capacitor. GCS16823 and GCS16953 units are
equipped with a single condenser fan which operates dur
ing all compressor operation. All other GCS16 units are
equipped with two condenser fans. In GCS161603 and
GCS161853 units, both condenser fans are energized
upon receiving a first stage cooling demand. Condenser
fans draw air across both condenser coils during all com
pressor operation. In all other GCS16 series units, the
condenser fans operate independently and are staged
with the compressors.
