CALCULATING REMOTE CONDENSER
INSTALLATION DISTANCES
Line Set Length
The maximum length is 100’ (30.5 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 (-28.9
°
C) and 130
°
F
(54.4
°
C), with line set lengths of up to 100’ (30.5 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 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.
Maximum Line Set Distance Formula
Step 1. Measured Rise (35’ [10.7 m] Maximum) ______ x 1.7 = _______ Calculated Rise
Step 2. Measured Drop (15’ [4.5 m] Maximum) ______ x 6.6 = _______ Calculated Drop
Step 3. Measured Horizontal Distance (100’ [30.5 m] Maximum) = _______ Horizontal Distance
Step 4. Total Calculated Distance 150’ (45.7 m) = _______ Total Calculated Distance
