42 Low Speed Rotation Condition
Condition to decrease target pump motor rotation speed
in freeze cycle.
10 to 100%

Anti-Slush Control 50 Pump De-Energized Time
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.
0 to 90 sec.
0=ignore
(1 sec. increments)
50
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.
0 to 5 sec.

Hard Water
Control
60 Operating Condition
Condition to operate cloudy ice control in hard water
application indicated in percentage against target
integrated value. After icemaking water supply starts, ice
begins to form and freeze cycle integrated value reaches
a certain level. Then, additional water is supplied to dilute
concentrated icemaking water in water tank.

Control
70 Operating Temperature
Upper limit of operating temperature to control ice left in
water plate at the end of freeze cycle. Decrease amount
of harvesting water by reducing ice left in opening water
plate after freeze cycle.
SETTING CHANGE IS INEFFECTIVE.

Ice Bridge Control 73 Ice Bridge Control Hot Gas Valve De-Energized Time
Time to keep hot gas valve de-energized after 20 sec in
harvest cycle. Prevent ice bridge in bin by delaying ice
dropping time.
