Refrigeration & Defrost Settings
(Only for refrigerated models)
This unit is equipped with automatic and manual defrosting functions. With proper settings of
refrigeration function and auto-defrosting cycle, this unit can be used for continuous operation at low
temperature settings. Please note defrosting function will only be activated when actual temperature at
10
℃
or below.
10.1 Press the "Set/Confirm"
button, then press the Increase button to “6”, next press the "Set/Confirm"

10.5 Explanation for setting auto defrosting cycle:
a) "Defrost Timer" is the time interval between two cycles. For example, if this is set as "6", the
unit will defrost once every 6 hours.
To find out the suitable "defrost timer" setting, the frosting time duration should be counted from
start of the low-temperature operation to the point that the actual temperature start bouncing up
due to the frosting inside the evaporation chamber. Then set the "defrost timer" as somewhere
between 1/10-1/5 of the frosting time duration. For example, if the frosting time duration is 20
hours, the "defrost timer" can be set from 2-4 hours. High relative humidity will require more
frequent defrosting cycle.
b) "Defrost Period" is the time duration of each defrosting cycle. For example, if this is set as "3",
the unit will run a defrosting cycle for 3 minutes.
When the ambient temperature is higher than 25
℃
, like in summer, the recommended setting
is 30 seconds, otherwise, 1 min is considered as adequate. As ambient conditions may vary,
therefore, always try to find the most appropriate settings for your own particular ambient
condition.
