Bryant 576C, 569D, 569F manual Application Data 566D150-240, 566E150-240, Operating Limits

APPLICATION DATA — 566D150-240, 566E150-240

1.INSTALLATION — Select equipment to match or to be slightly less than peak load. This provides better humidity control, less unit cycling, and less part-load operation.

When selecting vapor line sizes, oil return must be evalu- ated, particularly at part-load conditions.

The indoor fan must always be operating when outdoor unit is operating.

Ductwork should be sized according to unit size, not build- ing load.

To minimize the possibility of air recirculation, avoid the use of concentric supply/return grilles.

Indoor equipment should be selected at no less than 300 cfm/ton.

2.REFRIGERANT PIPING — It is recommended that the refrigerant piping for all commercial split systems include a liquid line solenoid valve, a liquid line filter drier, and a sight glass.

For refrigerant lines longer than 75 lineal ft, a liquid line solenoid valve and a suction accumulator are required. Refer to the Refrigerant Specialties table.
