Legend:
Equivalent	Equivalent tubing length, including effects of refrigeration specialties devices
Length
Linear Length	Linear tubing length, feet
Liquid Line	Tubing size, inches OD.
Max Lift	Maximum liquid lift (indoor unit ABOVE outdoor unit only), at maximum permitted liquid line pressure drop
	S	Linear Length Less than 75 ft (23 m): Minimum 2.0° F subcooling entering TXV
	S	Linear Length Greater than 75 ft (23m): Minimum 0.5° F subcooling entering TXV
Suction Line	Tube size, inches OD
	See highlighted: Do not use with RTPF coil model
Charge	Charge Quantity, lbs. Calculated for both liquid line sizes (where applicable), but only with larger suction line size (where
	applicable)
DNU	Do Not Use (pressure drop exceeds available subcooling in this model)
NR	Not Recommended (use smaller liquid tube size)
NOTE:	For applications with equivalent length greater than 188 ft (57 m) and/0r linear length greater than 125 ft (38 m), contact
	your local Carrier representative.
