2) Test Mode Description
1. Forced Operation Function
1-3) When the Forced Operation is selected, the compressor and the F-Fan operate for 24 hours without
stopping.
1-4) When the unit is shifted to the Forced Operation, the Freezer and the Fridge temperatures will be
automatically set to -23℃ and 1℃ respectively.
1-5) When the Forced Operation is selected, the Power Freeze function won't work.
(All the buttons will operate normally.) And, when the Power Freeze function is selected, the Power
Freeze LED will go off in 10 seconds.
1-6) When the Forced Defrost or Test Cancellation Mode is selected within a minute with the Forced
Operation being selected, the set temperature will be changed to the previously set operating
temperature.
1-7) The alarm sound during the Forced Operation keeps on until the Forced Operation completes and
there is no cancellation function.
3. Test Cancellation Mode
3-1) When turning the display panel into the Test mode and pressing the TEST button once more during
the Forced F-Defrost, the Forced F-Defrost will be cancelled and it will go back to the normal
operation. Also, when the unit is plugged out and in again, the Test mode is to be deactivated.
1-1) When any button is pressed once during the Test Mode, it will
enter the Forced Operation.
When it starts the Forced Operation, the LED Lamps indicating the
Fridge Temperatures (1℃, 2℃, 3℃, 5℃, 7℃) and the Freezer
Temperatures (-23℃,-21℃,-19℃, -17℃,-15℃) will be on showing
that it is on the Forced Operation.
At this time, it starts alarming with "Beep" sounds.
1-2) When the Forced Operation is selected, the compressor starts
without a 7-minute delay in any operation mode.
At this time, when it is in a Defrost mode, it stops defrosting and
the Forced Operation begins. (If the Forced Operation begins as
soon as the compressor stops, it may cause the overload.
So, take care when entering into the Forced Operation.)
2. Forced Defrost Function
2-1) When it is on the Forced Operation during the Test Mode, press
any button once. Then, the Forced Operation will stop immediately
and it will go into the Forced F-Defrost. When it enters the Forced
F-Defrost, it indicates that it is on the Forced F-Defrost mode by
turning on "3℃", "5℃" and "7℃" temperature LEDs on the Fridge
Display Panel and "-15℃", "-17℃" and "-19℃" temperature LEDs
on the Freezer Display Panel.
2-2) At this time, it sends out "Beeping" sound for 3 seconds.
This alarm sound repeats 0.75 sec On and 0.25 sec Off which
keeps on until the Forced F-Defrost finishes.
