REMOVAL OF FAN SHROUD
1. Disconnect all power to the 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.
The suction line temperatures in Table 4 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.

The correct system R-410A charge is shown on the unit
nameplate. Optimum unit performance will occur with
a refrigerant charge resulting in a liquid subcooling as
shown in Table 5. If charge is in doubt, reclaim and
recharge to factory nameplate charge.

FAN BLADE SETTING DIMENSIONS
Shown in Figure 11 is the correct fan blade setting for
proper air delivery across the outdoor coil. Refer to
Table 3 for unit specific dimension.
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.
R-410A
REFRIGERANT CHARGE
AHRI capacity and efficiency ratings are based on
testing done with the unit charged to the serial plate
charge. This unit has been charged to the serial plate
charge. The following pressure tables and sub-cooling
or superheat charts show nominal pressures and
temperatures for the unit. Many different problems can
affect the pressure and temperatures. These should only
be used by certified technicians as a guide for evaluating
proper charge. They shall not be used to adjust charge.
If charge is in doubt, reclaim, evacuate and recharge the
unit to the serial plate charge.
