CALCULATING REMOTE CONDENSER
INSTALLATION DISTANCES
Line Set Length
The maximum length is 100' (30.5 m).
The ice machine compressor must have the proper oil
return. The receiver is designed to hold a charge
sufficient to operate the ice machine in ambient
temperatures between -20°F (-28.9°C) and 120°F
(49°C), with line set lengths of up to 100' (30.5 m).
Line Set Rise/Drop
The maximum rise is 35' (10.7 m).
The maximum drop is 15' (4.5 m).
Calculated Line Set Distance
The maximum distance is 150' (45.7 m).
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.
(Example: A condenser located 10 feet above the
ice 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 the ice
machine has a
calculated drop
of 66 feet.)
3. Insert the
measured horizontal distance
into the
formula below. No calculation is necessary.
4. Add together the
calculated rise, calculated drop,
and
horizontal distance
to get the
total calculated
distance.
If this total exceeds 150' (45.7 m), move
the condenser to a new location and perform the
calculations again.

!
Caution
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.
