OPERATING INSTRUCTIONS & INSTALLATION

1)Forced Start Operation Function

1-1) Forced start operation is selected if the test key is pressed once while in the test mode. At that time the buzzer executes an alarm by making a beep sound.

2-1) If forced start operation is selected , then COMP. operates immediately without a 5 minute delay, regardless of operating mode. If it is during defrosting, defrosting shall promptly stop.

3-1) If forced start operation is selected, then the COMP. and F FAN perform a PULL-DOWN operation for 24 hours while the R compartment is controlled by the set temperature.

4-1) The forced start operation is performed continuously performed until completed, canceled or converted to an other mode (forced F, R, CF, CR defrosting).

5-1) If the forced start operation is selected , then along with it, a automatic selection is made for the F compartment

”-13

and for the R compartment “33.8

These settings are not changed (maintains “-13

and “33.8

)

even if forced defrosting or test cancellation is selected after more than 1 minute elapses under the condition

 

where forced start operation has been selected Nevertheless the setting are restored to the temperatures that

were set before the change to ”-13

and “33.8

if forced defrosting or test cancellation is selected before 1

minute elapses from the time when the forced start operation was selected.

6-1)If forced start operation is finished(24 hours), then F, CF compartment defrosting is executed regardless of previous condition.

7-1) Next, it proceeds normal defrosting opera according to CASE judgment, performing defrosting of the R compartment defrosting.

8-1) If randomly canceled during forced start operation (by cancellation mode), the COMP. ON time period during the forced start operation is also added to the accumulation to be considered for the defrosting period.

9-1) The power freezing and power refrigeration functions do not work during forced start operation. If any of these functions is selected, the LED display for the selected POWER function turns off spontaneously after approximately 10 seconds..

2)Forced Defrosting Function

1-1) If test button is pressed a second time, then R compartment / CR compartment defrosting is executed, and if the test button is pressed a third time, then simultaneous defrosting of F, CF, R, CR compartments is executed, and a beeping sound alarm is also executed.

2-1) The beeping sound alarm is executed until completion time of the heating and pause time.

3)Test Cancellation Mode

3-1) If the display panel is converted to the test mode and the test button is pressed once more, under the simultaneous defrosting condition, then defrosting of freeze and refrigeration partitions is canceled simultaneously to return to normal operation. Or if main power is turned on after turnoff, then all test functions are canceled.
