c. Insert measured horizontal distance into formula. No calculation is necessary. (6 ft.) [1.828 me-
ters].
d. Add the calculated rise, calculated drop, and horizontal distance together to get the total calcu-
lated distance (25.5 + 52.8 + 6) equals 84.3 ft. [25.694 meters]. If 100 ft. [30.48 meters] total cal-
culated distance is exceeded, the condenser must be moved to a new location which permits
proper equipment operation.
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.
3. 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.
4. Connection of Line-Set
A. Remove the plastic caps from the line-set, the condenser, and the ice machine.
B. Apply refrigeration oil to the threads on the quick connect couplers before connecting them to the con-
denser.
C. Carefully thread the female fitting onto the condenser or ice machine by hand.
D. Using the proper size wrench, tighten the couplings until they bottom out. Turn an additional 1/4 turn
to ensure proper brass-to-brass seating.
