CALCULATING REMOTE CONDENSER & REMOTE CONDENSING UNIT INSTALLATION DISTANCES
Line Set Length
The maximum tubing length is 30 meters (100 feet).
Line Set Rise/Drop
The maximum rise is 10.7 meters (35 feet).
The maximum drop is 4.5 meters (15 feet).
,
Caution
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 45 meters (150 feet).
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.
2. Insert the measured drop into the 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.
4. Add together the calculated rise, calculated drop, and
horizontal distance to get the total calculated distance.
If this total exceeds 45 meters (150 feet), move the
condenser/condensing unit to a new location and
perform the calculations again.
