REMOTE CONDENSER LOCATION
1.
Physical Line-Set Length: 55 Ft. Maximum [16.764 meters]
The ice machine compressor must have the proper oil return. Line-set rises, drop, or horizontal runs
greater than the maximum distance allowed will exceed the compressor start up and pumping design
limits, and will result in poor oil return to the compressor.
Line-Set Rise: 35 Ft. Maximum [10.66 meters]
Line-Set Drop: 15 Ft. Maximum [4.57 meters]
2.
Calculated Line-Set Distance: 100 Ft. [30.48 meters] (See Figure 24)
To prevent the combination of rises, drops and horizontal runs exceeding the compressor start-up
and pumping design limit, the following calculations should be made:
NOTE: Max. line–set for IMI Cornelius cubers is 55 ft. Do not confuse line length with calculated
line distance
A - (RISE) CONDENSER HIGHER THAN EVAP.
MAX. 35 FT.
B - LINE LENGTH 15 FT.: EXAMPLE
B - LINE LENGTH 35 FT.: EXAMPLE
C - (DROP) CONDENSER LOWER THAN EVAP. 15 FT.: MAX.

Examples:
a.
Insert measured rise (R) into the formula and multiply it by 1.7 to get a calculated rise (See
Figure 25).
example:
A condenser located 15 ft. [4.572 meters] above the ice machine has a 25.5 ft.
[8.874 meters] calculated total (15 ft. x 1.7 = 25.5).
