CALCULATED LINE SET DISTANCE
The maximum calculated distance is 150' (45.7 m).
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.
(Example: A condenser located 10 feet above the
ice machine has a
calculated rise
of 17 feet.)
2. Insert the
measured drop
into the formula below.
Multiply by 6.6 to get the
calculated drop.
(Example. A condenser located 10 feet below the
ice machine has a
calculated drop
of 66 feet.)
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 150'
(45.7 m), move the condenser to a new location
and perform the calculations again.
