Function & How- to-use By Products

2) Water Supply

It is the movement to supply water on the ICE-TRAY by using the SOLENOID VALVE after the completion
of the ejection (Ejection after the completion of the normal ice making or that by the test movement)
Considering cases with low hydraulic pressure, when it is recognized as No Water Supply, the Water Supply
will be attempted for 4 times.

2-1) Specifications for water supply

- After the completion of the normal ejection and the opening of the water supply valve, water is supplied for
the previously set OPTION time (Set by the DIODE in PCB and normally for 5 sec) and the water supply
valve gets off.
- Water is supplied regardless of the F/R-DOOR OPEN
- While supplying water, the ICE TEST S/W doesn't work.
- In one min. and 30 sec. after the completion of water supply, Water Supply/ No Water Supply will be
judged.
- Under the condition of additional water supply due to No Water Supply, the additional water supplying time
is 1.5 sec, 1 sec, and 2 sec.
- When judging water supply after the trial of water supply within the number of previous water supply,
complete water supply. In this case, the Ejection Stand-By Time is 55(60) min.
- To prevent the additional water supply by the judgment of No Water Supply due to the ice cube on the tray
cube which the ice maker sensor of the ICE-TRAY is, quit the water supplying movement for one time
when it is judged as No Water Supply after trying to supply water as many as the number of the previous
water supplying. After POWER ON, the number of the previous water supplying will be considered as
once for the first water supplying and when No Water Supply is judged after the initial water supplying, quit
the water supply movement. If the number of the previous water supply is three times, supply water for 3
times, and when judged as No Water Supply, quit the water supplying movement. In this case, the
Ejection Stand-By Time is 70~100 min.
- When judged as No Water Supply in the previous water supply, supply water for 5 sec, 1.5sec, 1sec,and 2
sec for 4 times.
- According to conditions, the Ejection Stand-by Time is as follows.

2~4

2-2) Judgment of Water Supply by the ICE-TRAY Temp sensor

- In one and a half min after the completion of the water supply, judge either the Water Supply or the No
Water Supply by comparing the temp change of the ice maker sensor on the ICE TRAY.
- In the case that the temp of the ICE-TRAY ice maker sensor in one and a half min. after the completion of
the water supply is 2 degrees (5 COUNT) higher than that during the water supply movement, it is judged
as the Water Supply and when the temp increases or decreases less than 2 degrees, it is considered as
the No Water Supply.

2-3) Specifications of water supply movement upon pressing the Ice Test S/W

- Supply water for once regardless of the previous water supply.
- The Ejection Stand-by Time after the completion of water supply is the same as that after the completion
of the previous water supply movement regardless of the Water Supply/ No Water Supply recognition.
- Do not change the number of the previous Water Supply. That is, if the number of Water Supply before
pressing the ICE TEST S/W is 3 times, that of the previous Water supply after the completion of the Water
Supply by pressing the ICE TEST S/W is also 3 times.
