5 Defrosting Period 1. Defrosting Mode 1. What to be considered in determining Defrosting Period
1) Total Run-time of COMP : 6, 8, 10, 12, 14 hours
2) Running-rate of COMP (each 2hours running-rate) : more than 80%
3) Total time of Door openings : 10minutes
4) Total Time (COMP-On + COMP-Off) : 60hours
5) Ambient Temperature : more than 35
6) In each Error : R1, F1, D1, F3, RT-S, Door-SW Error
2. Terms to start Defrosting Period
1) The Defrosting starts with the following conditions, in case total
COMP-run time passes 6, 8, 10 or 12hours
¨ çwhen an Error occurs
¨ èwhen running-rate of COMP is more than 80%
¨ éwhen total Door-opening time is more than 10minutes
¨ êwhen the ambient temperature is more than 35
2) Defrosting starts unconditionally when total COMP-run time passes
14 hours, under the condition that terms of 1) are not satisfied.
3) Defrosting starts immediately when Total-time (COMP-On + Off time)
is more than 60 hours, under the condition that terms of 1) and/or 2)
are not satisfied.

1. Defrosting Period
1) Time : 50minutes
2) COMP and F-Fan are On, R-fan is in
Control, and HTR is off
3) Pre-cool turns off when F-Sensor -27 .
1) Heater turns off when D-Sensor 10 .
2) Limit time : 80minutes
3) Heater continues to be On for 40 minutes
of limit time when D-Sesor is in error.
4) Limit time
30seconds: Heater continues to be On
after Defrosting regardless of D-Sensor
temperature.
40minutes: in case of D1-Error
80minutes: in normal control state
1) Time : 4minutes
2) COMP, F-Fan and R-Fan are Off.
1) Time : 5minutes
2) Only COMP is On, while F or R-Fan is Off.
