A pressure table can be found later in the manual covering all models. It is imperative to match the correct pressure table to the unit by model number. Manual 2100-400 Page 15 TROUBLESHOOTING 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. FIGURE 9 FAN BLADE SETTING TABLE 5 FAN BLADE SETTING DIMENSION Dimension Model A WL423 WL484 1.75 WL602 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. 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.

If there is any doubt as to correct operating charge being in the system, the charge should be removed, system evacuated and recharged to serial plate instructions. NOTE: Pressure table based on high speed condenser fan operation. If condensing pressures appear elevated check condenser fan wiring. See “Condenser Fan Operation” on Page 14.
