FUNCTIONS
Defrost Mode
A. When total operation time of compressor becomes: 6, 8, 10, 12 hours.
- any error mode-R1, D1, F3, C1, RT/S, Door SW error- happens.
- or, running rate of COMP (per 2hrs of total operation time) is more than 80%.
- or, total door open time is over 3 minutes.
- or, ambient temperature (RT) is more than 40C.
B. Even if the above condition “A” is not satisfied,
- Defrost mode starts immediately when total operation time of COMP is 14hrs.
- or, defrost mode starts immediately as long as total time (COMP on time + COMP off time) is 60 hrs.
A. General Defrost Mode
- How to start: By conditions of defrost
- Process :
General operation-
“PRE-COOL” - Defrost Heater on- Pause(10 min)-General operation
; PRE-COOL: When the defrost heater works, the temp. of freezer increases.
So the COMP works for 25 min before defrost mode.
- Limited Time of Defrost Heater
; 40 minutes: Heater turns off when “D SENSOR” is OPEN or SHORT.
; 60 minutes: Heater turns off after maximum 60 minutes.
- Heater Off: When the temperature at “D SENSOR” is over 10C
B. Forced Defrost Mode
- How to start: by press “TEMP” button for continuously and “S-COOL” button 5 times.
- Process: same as General Defrost Mode except “PRE-COOL”
; Heater is supposed to be on Initial 30 seconds even though the temp. at “D SENSOR” is over 10C.
(for TEST)
- How to confirm: by press “S-COOL” button for continuously and “TEMP” button 5 times.
And then, the mode displays.
- Display : led lamps “NOR”& “S-COOL” on, “MAX-NOR” & ”MAX” on/off continually
