Application Data - Bryant 566D User Manual

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.
