7-2 Function of Ice maker
7-2-1 Initial control function
1. The level of the ice-removing tray (ice-removing container) after completing the MICOM initialization in the initial POWER
ON ,returning to electricity failure and turning-off of ice-making stop switches. Namely, detection lever operates up and down.
2. The level of ice-removing container is detected with high / low output signal of hall sensor.
In another words, operation is performed in order to keep a level by operating ice-removing motor so that high or low volt-
age could be applied in the MICOM PIN.
3. No signal change of hall sensors until a minute after operating the ice-removing motor should be considered as failure. In
this case, stop the automatic ice-remover and then reset the ice-maker initialization if considered as normal after perform-
ing continuous check in a cycle of an hour.
4. Keeping of the ice-removing tray (ice-removing
container) should be considered initial control is completed.
7-2-2 Water supply control function
1. Supply water into the ice-removing tray by operating the ice solenoid placed at the machine room of refrigerator using the
time check function if considered as the level is kept after performing a horizontal operation of the ice-making tray after
the ice-removing control (normal ice-removing control, ice-removing control of test function) is completed.
2. The quantity of water supply is determined by supplying water for a constant using the dip switch.

Remarks
The quantity of water supply may differ depending on
the setting status of the dip switch or on water pressure
as water supply method is of a pattern of direct connec-
tion to water cock.
3. The change of the quantity of water supply setting may be done according to the changed time even after changing it
without powering off. In the change of dip switch during water supply, it is done according to the water supply time previ-
ously established and then done according to the additionally changed time from the next water supply.
Water supply control switch
__
* Adjust the water supply control switch to adjust the
amount of water being supplied.
* Make sure it is adjusted to meet the line indicating the
adequate amount of water supply.
7-2-3 Ice-making
control
function
1. Ice-making control is related with when considered as water within ice-making tray (ice container) turns into ice com-
pletely after completing water supply operation and performs ice-making completion operation by detecting temperature
of ice-making tray. (ice-making sensor is mounted on the bottom of the ice-making tray).
2. Ice-making control begins after completing water supply control or initial control.
3. It is considered that ice-making is completed if temperature of ice-making sensor arrives at -6°C after 60 minutes pass
from the time water is supplied to the ice-making tray.
4. It is considered that ice-making is completed if temperature of ice-making sensor arrives at below -7°C after 10 minutes
pass at the above status.
