Except for the door open alarm and failure alarm can be carried out in the locking state, others
button operations shall be conducted in unlocking state.
9.3.4 High temperature alarm
When Tf ≥ -8 °C and duration ≥ 36 hours. (< -8 °C and the duration is cleared) (It must be detected
once that the temperature of frozen sensor is lower than -15 °C for judgement), then enter the
over-temperature alarm, the high-temperature alarm indicator lights up; the buzzer sounds for 10
seconds at 1Hz frequency and then sounds for 10 seconds every 30 minutes.
The alarm is released when Tf < -12 °C. Operate any key to cancel the buzzer alarm.
9.4 Defrosting function
◆ Defrosting theory:
The defrosting of evaporator is realized by the heating of heater, following the temperature rise, the frost
on evaporator becomes water, and the water flow into the evaporating pan via the draining system, the
water in evaporating pan evaporate away finally
◆ Defrosting steps:
Compressor shutdown--- the freezer fan motor closed, the heater start working ---the heater stop when
the temperature rise to setting--- after 7 minutes, the compressor will start--- after 8 minutes, the fan
motor will start work
◆ Meet one of the following conditions , defrost heating exit:
1) When the defrosting sensor has no fault, the measured temperature Tfd ≥ the set temperature 12℃
(54℉) which frozen defrost heating exit and the set temperature 7℃(45℉) which refrigerat defrost
heating exit
2) When the defrosting sensor has no fault, the defrosting time is ≥ 60 minutes
3) When the defrosting sensor is faulty , the heater will stop after work 20 minutes
9.5 Open door alarm
