NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside the factory
default setting may result in damage to the appliance.
This dip switch setting provides slush control during the freeze cycle.
Disabled (OFF): When the evaporator temperature reaches 41°F (5°C) the control board
reads a 4.8 kΩ signal from the thermistor and de-energizes the water pump for 10 sec.,
then energizes the water pump for the duration of freeze time.
Enabled (ON): When the evaporator temperature reaches 50°F (10°C) the control board
reads a 3.9kΩ signal from the thermistor and de-energizes the water pump for 10 sec.
and energize it for 50secs. repeatedly. When 34°F (1°C) is reached, a 5.9 kΩ signal
causes the control board to de-energize the pump motor for 10 secs., energize it for 50
secs., de-energize it again for 10 secs., then energize it continuously.
