ADVICE
In order to prevent frost from building up in the evaporator, causing the cooling effect to deteriorate, the
defrost timer (set at 6 hours when the unit is shipped from the factory) runs and carries out defrosting
automatically. When defrosting ends, the unit switches to cooling automatically. The evaporator fan also
stops during defrosting and warm air is not blown into compartment.
Press the [MODE] switch (3 times if the refrigeration unit is stopped and 2 times if it is running) to
change the display to the defrost timer display.
Using the (built-in) forced defrost end timer, the unit changes to the cooling operation
automatically after 60 minutes.
1The setting temperature displayed in the digital display will blink if the [UP] switch or [DOWN]
switch is pressed, then the mode will change to the defrost timer setting mode. Pressing the switch
again changes the display to the setting time display.
2Set the desired time in the digital display, then press the [SET] switch. The defrost timer’s time
setting will be finalized and the setting operation will close.
If frost is forming on the evaporator and cooling of
the compartment is becoming difficult, you can
defrost it manually.
• When you desire to defrost manually, press the
Defrost switch during a cooling operation.
(During a defrost operation, the defrost display
is shown in the display.)
• When defrosting is completed, the unit
automatically returns to the cooling operation.
(You cannot stop operation by carrying out
manual defrosting.)
• Each time the [UP] switch is pressed, 1 hour is added to the displayed time.
• Each time the [DOWN] switch is pressed, 1 hour is subtracted from the displayed time.
