of F/R-Room buttons, POWER FRE button and POWER REF button as a Test button.
●
If press TEST KEY, the Test function will be selected in the order of forced operation 1 (FF 1)→forced operation 2 (FF 2)
→forced operation 3 (FF 3) →forced R, F defrost(fd)Cancellation (steady operation)→forced operation 1 (FF 1)
If you want to cancel the function during TEST function achievement, power ON after OFF is the most desirable method.
① Forced Operation Function
1) If press Test Key 1 times in Test Mode, Display is registeredby FF1 and means forced operation 1. This time, Buzzer achieves
warning at Beep sound.
2) FF3 is displayed if press FF 2, 1 times more if press Lock key 1 times more in forced operation 1
and each means forced operation 2,3 and each moves differing each Comp's RPM.
3) When the Forced Operation is selected, the Comp operates immediately without a 5-minute delay.
This time, defrost has to be discontinued immediately if is doing defrost.
4) When the Forced Operation is selected,the F &R-Room temps will be automatically selected to -13℉and
34℉ respectively.But,when the Forced Defrost or Test cancellation is selected after 1 minute elapsed while Forced
Operation ,the temperatures do not change they will be maintained at “-13℉” and “34℉”,and when the forced defrost or
Test operation is cancelled within a minute or the Forced Operation selection,the temperatures change to the previously selected
temperatures.
5) Upon completion of the Forced Operation (24 hours),both compartments perform a Defrost regardless of their previous operating
conditions.
6) After the above,Defrost operates under normal defrost conditions according to the setting controlling the R-Defrost.

function is selected,the relevant LED lights up and it goes off in about 10 seconds.
② Forced Defrost Function
1) If press Lock key more 1 times in forced operation 3 (FF 3) Display is registeredFdforced operation immediately cancled,
defrost of F and R achieve at same time.
2)This time, Beep alarm sound produces while achieve forced F, R defrost operation at 0.75 seconds
ON/0.25 seconds OFF sound after ring for 3 seconds from injection visual point.
③ Test Cancellation Mode
1) When converting the Display Panel into the Test mode and pressing a Test button once more during the simultaneous
Forced F/R-Defrost,the Forced operation will be cancelled simultaneously and restored to its normal operation.
