Water 36 Water Regulating Valve Error Detection Temperature
Regulating Thermistor temperature (water regulating valve
Valve outlet) in case of water regulating valve error and
cooling water failure for water-cooled model.

Pump 40 Type
Motor Selection of pump motor type.

41 Target Rotation Speed
Normal pump motor rotation speed set with the first
two digits of rotation speed.
e.g. 3800 r/min = "38"
When freeze cycle integrated value against target
is less than low speed rotation condition (CB
Setting 42), pump motor operates at target rotation
speed. When integrated value is low speed rotation
condition (CB Setting 42) or higher, target rotation
speed is decreased by low speed rotation rate (CB
Setting 43).
42 Low Speed Rotation Condition
Condition to decrease target pump motor rotation
speed in freeze cycle.
43 Low Speed Rotation Rate
Percentage against target rotation speed (CB Setting
41).
Anti-Slush 50 Pump De-Energized Time
Control Pump de-energized time for anti-slush control to de-
energize pump after 2 min at evaporator temp of 3 to
4°C, quickly refrigerate evaporator before icemaking
water
supercools, and form ice core. When set to "0", there
is no anti-slush control.
51 Anti-Slush Control Water Supply Time
Time to supply water while pump is de-energized for
anti-slush control. If slush ice is too much and cannot
be prevented solely by pump de-energized time (CB
Setting 50), water is supplied while pump is de-
energized to slightly raise tank water temp.
