Normal Operation - Manitowoc UDE065A Technician's Handbook

Normal Operation

Example below is for normal operation at 86°F (30°C) air
temperature 68°F (20°C) water temperature.
FREEZE CYCLE
• Normal suction line temperature at the compressor
will range from 86°F (30°C) three minutes into the
cycle to 8°F (-13°C) at the end of the freeze cycle.
• Normal discharge line temperature at the compressor
will range from 168°F (76°C) to 140°F (60°C) through
the freeze cycle.
HARVEST CYCLE
Suction line temperature at the compressor will range
from 64°F (18°C) to 111°F (44°C) through the harvest
cycle. An obstructed capillary tube will not effect suction
line temperature range during the harvest cycle. Low
refrigerant charge will have a lower temperature than
normal.
Discharge line temperature at the compressor will range
from 180°F (82°C) to 150°F (60°C) through the harvest
cycle.
Ice fill pattern will vary depending on severity of the
obstruction or refrigeration loss. Ice fill patterns will range
from no ice on the entire evaporator to thin only at the
evaporator outlet (thin at the bottom, thick at the top of
the evaporator).
