DISCHARGE LINE TEMPERATURE ANALYSIS

Q130/Q170/Q210/Q270 Ice Machines Only

GENERAL

Knowing if the discharge line temperature is

increasing, decreasing or remaining constant can be

an important diagnostic tool. Maximum compressor

discharge line temperature on a normally operating ice

machine steadily increases throughout the freeze

cycle. Comparing the temperatures over several

cycles will result in a consistent maximum discharge

line temperature.

Ambient air temperatures affect the maximum

discharge line temperature.

Higher ambient air temperatures at the condenser =

higher discharge line temperatures at the compressor.

Lower ambient air temperatures at the condenser =

lower discharge line temperatures at the compressor.

Regardless of ambient temperature, the freeze cycle

discharge line temperature will be higher than 150°F

(66°C) on a normally operating ice machine.

PROCEDURE

Connect a temperature probe on the compressor

discharge line within 6" (15.2 cm) of the compressor.

Observe the discharge line temperature for the last

three minutes of the freeze cycle and record the

maximum discharge line temperature.
