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.
