Section 2
Calculating Installation Distances
Line Set Length
The maximum tubing length is 100 feet
(30 meters).
Line Set Rise/Drop
The maximum rise is 35 feet (10.7 meters).
The maximum drop is 15 feet (4.5 meters).


Notice
If a line set has a rise followed by a drop,
another rise cannot be made. Likewise,
if a line set has a drop followed by a rise,
another drop cannot be made.

Calculated Line Set Distance
The maximum calculated distance is
150 feet (45 meters).
Line set rises, drops, horizontal runs (or
combinations of these) in excess of the
stated maximums will exceed compressor
start‑up and design limits. This will cause
poor oil return to the compressor. Make the
following calculations to make sure the line
set layout is within specifications.
1. Insert the measured rise into the
formula below. Multiply by 1.7 to get
the calculated rise.
Insert the measured drop into the
2.
formula below. Multiply by 6.6 to get
the calculated drop.
3. Insert the measured horizontal
distance into the formula below. No
calculation is necessary.
Add together the calculated rise,
4.
calculated drop, and horizontal
distance to get the total calculated
distance. If this total exceeds 150 feet
(45 meters), move the condenser/
condensing unit to a new location and
perform the calculations again.
