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 (-29°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 calculated 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.

Maximum Line Set Distance Formula

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.

Step 1. Measured Rise (35' [10.7 m] Maximum) ______ x 1.7 = _______ Calculated Rise

Step 2. Measured Drop (15' [4.5 m] Maximum) ______ x 6.6 = _______ Calculated Drop

Step 3. Measured Horizontal Distance (100' [30.5 m] Maximum) _______ Horizontal Distance

Step 4. Total Calculated Distance 150' (45.7 m) _______ Total Calculated Distance
