REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit
rating plate. Optimum unit performance will occur with
a refrigerant charge resulting in a suction line
temperature (6" from compressor) as shown in Table 6.
The suction line temperatures in table above are based
upon 80° F dry bulb / 67° F wet bulb (50% R.H.)
temperature and rated airflow across the evaporator
during cooling cycle.

FAN BLADE SETTING DIMENSIONS
Shown in Figure 9 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.
