FAN BLADE SETTING DIMENSIONS
Shown in Figure 10 is the correct fan blade setting
dimension for proper air delivery across the outdoor coil.
Any service work requiring removal or adjustment in the
fan and/or motor area will require that the dimensions
below be checked and blade adjusted in or out on the
motor shaft accordingly.
