REFRIGERANT CHARGE

The correct system R-22 charge is shown on the unit
rating plate.  Optimum unit performance will occur with
a refrigerant charge shown on the unit serial plate.

If correct charge is in doubt, recover the refrigerant and
recharge per the charge on the unit rating plate.  See
Table 7 for proper subcooling levels for evaluation of
proper charge.

FAN BLADE SETTING DIMENSIONS

Shown in Figure 13 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.

Expected subcooling levels during cooling operation.
Above subcooling levels are provided to troubleshoot low
charge or overcharged conditions.  If charge is in doubt,
evacuate and recharge the unit to the refrigerant charge
listed on the serial plate.
