Section 2Installation References2-14CALCULATING REMOTE CONDENSERINSTALLATION DISTANCESLine Set LengthThe maximum length is 100’ (30.5 m).The ice machine compressor must have the proper oilreturn. The receiver is designed to hold a chargesufficient to operate the ice machine in ambienttemperatures 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/DropThe maximum rise is 35’ (10.7 m).The maximum drop is 15’ (4.5 m).CAUTIONIf a line set has a rise followed by a drop, anotherrise cannot be made. Likewise, if a line set has adrop followed by a rise, another drop cannot bemade.Calculated Line Set DistanceThe maximum distance is 150’ (45.7 m).Line set rises, drops, horizontal runs (or combinationsof these) in excess of the stated maximums willexceed compressor start-up and design limits. Thiswill cause poor oil return to the compressor.Make the following calculations to make sure the lineset 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 theice 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 theice machine has a calculated drop of 66 feet.)3. Insert the measured horizontal distance into theformula below. No calculation is necessary.4. Add together the calculated rise, calculateddrop, and horizontal distance to get the totalcalculated distance. If this total exceeds 150’(45.7 m), move the condenser to a new locationand perform the calculations again.Maximum Line Set Distance FormulaStep 1.
