Equivalent
Length Equivalent tubing length, including effects of refrigeration specialties devices
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
SLinear Length Less than 75 ft (23 m): Minimum 2.0° F subcooling entering TXV
