NOTES:

1.Select air handler at no less than 300 cfm/ton (nominal condens- ing unit capacity).

2.Total combined draw of the field-supplied liquid line solenoid valve and air handler fan contactor must not exceed 22 va. If the speci- fied va must be exceeded, use a remote relay to control the load.

1.LIQUID LINE — For applications with liquid lift greater than 20 ft, use 1/2-in. liquid line where 3/8 in. is shown; use 5/8-in. liquid line where 1/2 in. is shown. The maximum liquid lift is 60 ft.

NOTES:

1.Pipe sizes are based on a 2° F loss for liquid and suction lines.

2.Pipe sizes are based on the maximum linear length, shown for each column, plus a 50% allowance for fittings.

3.Charge units with R-22 in accordance with unit installation instructions.

-120, 576C120, 569F120

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.
