11-2) ICE-MAKER function(FTA/DTA)
This is an instruction about the function of ICE-MAKER, which is optional.
ICE-MAKER makes ice automatically and continually. The automatic ice maker makes and store
ice in the ice storage bin. ICE-DISPENSER (FTA/DTA) is a model which dispenses ice made to the
outside through the freezer compartment door.
1. First operation function
1) When Power is off and on again, there is no operation for 2 seconds. And then, after
initialization of MICOM, the horizontality of ICE-TRAY is sensed.
2) By ON/OFF of HOR/INV S/W (ÒHIGHÓ/ÓLOWÓ), the horizontality of ICE-TRAY is sensed.
In other words, as shown in the following table, HOR/INV S/W and LEVER S/W are OFF and
then, HIGH voltage (usually DC 5V) is under supplying or is to be supplied to MICOM PIN NO
#50 and #51 by operating Eject Motor to make ICE-TRAY in horizontality.
3) If ICE-TRAY is sensed to be in a horizontality, stand-by for 2 hours (1 cycle time) is maintained.
This means that stand-by for horizontality of the ice-tray is maintained for 2 hours after the first
POWER ON.
4) After 2 hours of stand-by, the temperature is sensed by the ice-maker sensor at the bottom side
of ICE-TRAY and when -10 continues for more than 5 minutes, eject function operates to drop
the made ice in the ice tray into the ice storage bin by twisting the tray. This eject operation
performs regardless of the presence of ice in the ice tray.

2. Water supply function
1) After Eject function (first eject operation, normal eject operation and eject operation of TEST
function) is finished and the horizontality of ICE-TRAY is sensed, water is supplied to the
ice-maker by operating the water solenoid at the machine room on the time-check basis.
