CALCULATING REMOTE CONDENSER INSTALLATION
DISTANCES
Line Set Length
The maximum length is 100' (30 m).
The ice machine compressor must have the proper oil
return. The receiver is designed to hold a charge sufficient to
operate the ice machine in ambient temperatures between
-20°F (-29°C) and 120°F (49°C), with line set lengths of up to
100' (30 m).
Line Set Rise/Drop
The maximum rise is 35' (10.7 m).
The maximum drop is 15' (4.5 m).
! 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 150' (45 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.

Combination of a Drop and a
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 m), move the
condenser to a new location and perform the
calculations again.
