Remote Condenser Location - Cornelius CR1200 Service Maintenance Manual

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 great-
er 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]
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
Maximum Line-Set Distance Formula
A. Measured rise
B. Measured drop
C. Measured Horizontal Distance = actual measurement.
D. Total Calculated Distance (A+B+C)=Total Calculated Distance (100 ft. Max.) [30.48 meters]
Examples:
a. Insert measured rise (R) into the formula and multiply it by 1.7 to get a calculated rise.
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).
b. Insert measured drop (D) into formula and multiply by 6.6 to get a calculated drop.
example: A condenser located 8 ft. [2.438 meters] below the ice machine has a 52.8 ft. [16.093
meters] calculated total (8 ft. x 6.6 = 52.8 ft.).
