2-10. Frost removal function
1. Frost removal is performed whenever total operation time of compressor becomes 7 ~ 7.5 hour.
2. In providing initial power (or returning power failure), frost removal starts whenever total operation time of compressor
becomes 4 ~ 4.5 hour.
3. Frost removal is completed if temperature of a frost removal sensor becomes more than 5°C after starting frost removal.
Poor frost removal is not displaced if it does not arrive at 5°C even if two hours have passed after starting frost removal.
4. No removal is done if frost removal sensor becomes poor (snapping or short-circuit).
2-11. Sequential operation of built-in product
Built-in products such as compressor, frost removal heater, freezing room fan, Cooling Fan and step motor damper are
sequentially operated as follows for preventing noise and part damage occurred due to simultaneous operation of a lot of
parts in applying initial power and completing test.

If error occurs
during operation,

not done.
If pressing switch

immediately
returns to the test
