15 FT . (4.5 M)

MAXIMUM DISTANCE

Line Set Length

The maximum length is 100' (30.5 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m). The maximum drop is 15' (4.5 m).

35 ft. (10.7 m) Rise: The maximum distance the

Condenser or Condensing Unit can be above the ice machine.

15 ft. (4.5 m) Drop: The maximum distance the

Condenser or Condensing Unit can be below the ice machine.

34 Part Number STH026 2/12

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 Step 1

Measured Rise ____ X 1.7 = ______Calculated Rise (35 ft. Max)

Step 2

Measured Drop ____ X 6.6 = ______Calculated Drop (15 ft. Max.)

Step 3

Measured Horizontal Distance = _________Horizontal (100 ft. Max.) Distance

Step 4

SAFE OPERATION MODE

Allows the ice machine to operate up to 72 hours if the ice thickness probe (E19 fault) and/or water level probe sensors fail (E20 fault).

• When the control board starts the safe mode an alert is flashed on the LCD display to notify the end-user they have a production problem.

• The control board automatically initiates and monitors the safe mode. The control will automatically exit the safe mode if a normal signal is received from the input.

• After 72 hours the control board will enter a standby mode and turn off

NOTE: The control board needs a five cycle history to operate safe mode. If five cycles have never been successfully completed the ice machine will shut-off.

• Example - The ice machine is a new installation and the water has not been turned on. The ice machine will stop after five cycles with five long freeze cycles and five water system faults in the event log.
