REMOVAL OF FAN SHROUD
1. Disconnect all power to unit.
2. Remove the screws holding both grilles, one on each
side of unit, and remove grilles.
3. Remove screws holding fan shroud to condenser and
bottom – nine (9) screws.
4. Unwire condenser fan motor.
5. Slide complete motor, fan blade, and shroud assembly
out the left side of the unit.
6. Service motor/fan as needed.
7. Reverse steps to reinstall.
FAN BLADE SETTING DIMENSIONS
Shown in Figure 17 are the correct fan blade setting
dimensions 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.
The suction line temperatures in Table 9 are based upon
80ºF dry bulb/67ºF wet bulb (50 percent R.H.)
temperature and rated airflow across the evaporator
during cooling cycle.
