Warning
Potential Personal Injury Situation
The ice machine head section contains
the refrigerant charge. Installation and
brazing of the line sets must be performed
by a properly trained and EPA certified
refrigeration technician aware of the
dangers of dealing with refrigerant charged
equipment.
CALCULATING INSTALLATION DISTANCES
Line Set Length
The maximum tubing length is 100 feet (30
meters).
Line Set Rise/Drop
The maximum rise is 35 feet (10.7 meters).
The maximum drop is 15 feet (4.5 meters).
Notice
If a line set has a rise followed by a drop,
another rise cannot be made. Likewise,
if a line set has a drop followed by a rise,
another drop cannot be made.
Calculated Line Set Distance
The maximum calculated distance is 150
feet (45 meters).
Line set rises, drops, horizontal runs (or
combinations of these) in excess of the
stated maximums will exceed compressor
start-up and design limits. This will cause
poor oil return to the compressor. Make the
following calculations to make sure the line
set layout is within specifications.
1. Insert the measured rise into the
formula below. Multiply by 1.7 to get
the
calculated rise .
2. Insert the measured drop into the
formula below. Multiply by 6.6 to get
the
calculated drop .
3. Insert the measured horizontal
distance
into the formula below. No
calculation is necessary.
