Alternatively, if the set temperature is not so low as critical, in most cases, manual defrosting
will be adequate.
c) The proper of defrosting cycle can vary upon actual environmental conditions, preset
temperature value and running time. We recommend defrost at least 1-2 times per day, with
3-5 minutes for each cycle.
d) If after a defrosting cycle, there is still some ice inside the evaporator chamber (normally by
long term, low temperature operation) the “defrosting timer” needs to be shortened and/or the
“defrosting time” must be extended accordingly.
e) During the defrosting process, the actual temperature inside can have a temporary deviation of
3°C to the set point. This is normal, so does not require any action.
10.6 Explanation for setting Manual Defrosting cycle:
Alternatively, during the operation, the unit can run a manual defrosting cycle when necessary. To
activate the cycle, press button and hold for 3 seconds, the unit will start manual defrost for set
"defrosting period". To abort, press button and hold for 3 seconds. Minimum time interval
between two manual defrost cycles is 1 min.
Attention:
1.
The defrosting cycle will only be activated when the following requirement is fullfilled
；
Auto defrosting cycle : when both set and actual temperature is at or below
10
℃
; Manual defrosting cycle : when actual temperature is at or below 10
℃
.
2.
The cooling system keeps running during defrosting cycle, while the motor fan stops.
3.
The temperature will silently overshoot during defrosting, and then be stabilized when
defrosting terminates.
4.
For better temperature control during continuous low temperature operations,
for example, below 10.0°C, the following operations are recommended: Set
Defrost Timer:
“3” hr, Defrost Period: “0.7” min;
Weekly maintenance: Open the door and wipe off the condensation, set the
temperature at top value “65°C” and let it run for at least 1 hour to further
evaporate the condensations
inside the chamber.
5.
During defrosting cycle or heating up process, the drip tray should be place at the
unit's rear end and emptied on a regular basis.
