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 (8ft. x 6.6 = 52.8 ft.)
c. Insert measured horizontal distance into formula. No calculation is necessary. (6 ft.) [1.828 meters].
d. Add the calculated rise, calculated drop, and horizontal distance together to get the total calculated dis-
tance (25.5 + 52.8 + 6) equals 84.3 ft. [25.694 meters]. If 100 ft. [30.48 meters] total calculated distance
is exceeded, the condenser must be moved to a new location which permits proper equipment opera-
tion..
CAUTION: If a line set rise is followed by a line set drop, a second line set rise cannot be
made. or If a line set drop is followed by a line set rise, a second line set drop cannot be
made.
7. Lengthening Or Reducing The Line Set Lengths
In most cases, by routing the line set properly, shortening will not be necessary (refer to illustration). How-
ever when shortening or lengthening is required, do so before connecting the line set to the ice machine or
the remote condenser. This prevents the loss of refrigerant from the ice machine or the condenser.
The quick connect fittings on the line sets are equipped with Schrader Valves. Use these valves to recover
any vapor charge from the line set. When lengthening or shortening lines, apply good refrigeration practic-
es and insulate new tubing. Do not change the tube sizes. Evacuate the lines and place approximately 5
oz. of vapor refrigerant charge in each line.
