APPLICATION DATA — 569D072-120, 576C090-120, 569F120
OPERATING LIMITS
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 3/8in.isshown;use5/8-in.
liquid line where 1/2in. is shown. The maximum liquid lift is
60 ft.
MAXIMUM REFRIGERANT CHARGE
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.
