7-2-5 Function TEST
1. This is a compulsory operation for TEST, SVC, cleaning, etc. It is operated by pressing and holding the Fill Key for 3 seconds.
2. The test works only in the Ice Making Mode. It cannot be entered from the Harvest or Fill mode. (If there is an ERROR, it
can only be checked in the TEST mode.)
3. Caution! If the test is performed before water in the Maker is frozen, the Ejector will pass through the water. When the Fill
mode begins (Stage 4), unless the water supply has been shut off, added water will overflow into the ice bin. If the control
doesn’t operate normally in the TEST mode, check and repair as needed.
4. After water is supplied, the normal CYCLE is followed: ice making
→
Harvest
→
Fill
→
Park Position.
5. Five seconds after Stage 5 is completed, the Ice Maker returns to MICOM control. The time needed to supply water
resets to the pre- test setting.
