C - Condenser Fan Motor
All units use single-phase PSC fan motors which require a run
capacitor. In all units, the condenser fan is controlled by the
compressor contactor.
ELECTRICAL DATA tables in this manual show specifi-
cations for condenser fans used in 10ACCs.
Access to the condenser fan motor on all units is gained
by removing the seven screws securing the fan assem-
bly. See figure 8. The condenser fan motor is removed
from the fan guard by removing the four nuts found on
the top panel. See figure 9 if condenser fan motor re-
placement is necessary.
