1) Starting condition of Defrost Period
1.1- Accumulated running time of COMP : 6,8,10,12 hrs.
1.2- Running rate of COMP (per 2hrs of Accumulated running time) :
more than 80%
1.3- Accumulated running time of Door Open : 3 minutes.
1.4- Total time (COMP on time + COMP off time) : 60 hrs.
1.5- Room Temperature (RT) : more than 35°C
1.6- Errors of every kinds : R1, D1, F3, C1, RT/S, Door SW error.
2) Starting condition of Defrost Period
2.1- When satisfying the condition ‘1)’
2.2- Unless satisfying the condition ‘2.1’, when accumulated running
time of comp is 14hrs, defrost mode starts immediately.
2.3- Unless satisfying the condition ‘2.1, 2.2’, when total time (COMP on
time + COMP off time) is 60 hrs, defrost mode starts immediately.
1) General Defrost Mode
1.1- Start : By determination of defrost
1.2- Process : General operation – Heater on – Pause(4min) – General
operation – Heater defrosts: When the temperature at D-sensor is over
10°C, heater turns off – Limit time: 80 min (40 min on D Sensor
ERROR)
2) Forced Defrost Mode
2.1- Start: by press S-COOL for continuously and TEMP. CONTROL
button 5 times.
2.2- Process: same as General Defrost Mode
- Heater is supposed to be on Initial 30 seconds. (for TEST)
2.3- Display : led lamps ‘LOW-MID’, ‘MID-HIGH’, ‘S-COOL’ are on.
1) When power is on, if the temperature at the D-sensor is under 3.5°C,
then General Defrost Mode starts.
2) When initial defrost mode starts, heater will be on directly and defrost
mode will be started.
COMP. doesn’t work after COMP. turns off even though R-sensor is on
condition. (This is to protect comp.)
1) General operation : The COMP can’t be on within 6 min.
2) Operation of LOW RT : The COMP can’t be on within 30 min.
