14.2 Breakdown Self Diagnosis Function14.2.1 Self Diagnosis Function (Three Digits Alphanumeric Code)• Once error occurred during operation, the unit will stop its operation, and Timer LED blinks.• Although Timer LED goes off when power supply is turned off, if the unit is operated under a breakdowncondition, the LED will ON again.• In operation after breakdown repair, the Timer LED will not blink. The last error code (abnormality) will be storedin IC memory.14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.2 Press the CHECK button on the remote control continuously for 5 seconds.3 “- -“ will be displayed on the remote control display.Note: Display only for “- -“ (No signal transmission, no receiving sound andno Power LED blinking)4 Press the TIMER ▲ or ▼ button on the remote control. The code “H00” (noabnormality) will be displayed and signal will be transmit to the main unit.5 Each press of the button (▲ or ▼) will increase error code number andtransmit error code signal to the main unit.6 When the latest abnormality code on the main unit and code transmittedfrom the remote control are matched, Power LED will light up for 30seconds and a “beep” sound (continuously for 4 seconds) will be heard. Ifno codes are matched, Power LED will light up for 0.5 seconds and nosound will be heard.7 The breakdown diagnosis mode will be canceled unless pressing theCHECK button continuously for 5 seconds or operating the unit for 30seconds.8 The LED will be off if the unit is turned off or the RESET button on the mainunit is pressed.14.2.3 To Display Memorized Error Code (Protective Operation)1 Turn power on.2 Press the CHECK button on the remote control3 “- -“ will be displayed on the remote control display.Note: Display only for “- -“ (No signal transmission, no receiving sound and no Power LED blinking)4 Press the TIMER ▲ or ▼ button on the remote control. The code “H00” (no abnormality) will be displayedand signal will be transmit to the main unit.5 Each press of the button (▲ or ▼) will increase error code number and transmit error code signal to the mainunit.6 When the latest abnormality code on the main unit and code transmitted from the remote control are matched,Power LED will light up for 30 seconds and a “beep” sound (continuously for 4 seconds) will be heard. If nocodes are matched, Power LED will light up for 0.5 seconds and no sound will be heard.7 The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5seconds or operating the unit for 30 seconds.8 The same diagnosis can be repeated by turning power on again.14.2.4 To Clear Memorized Error Code after Repair (Protective Operation)1 Turn power on (in standby condition).2 Press the AUTO button for 5 seconds (a “beep” sound is heard) on the main unit to operate the unit atForced Cooling Operation Mode.3 Press the CHECK button on the remote control for about 1 second with a pointed object to transmit signal tomain unit. A “beep” sound is heard, and the Error Code is cleared.14.2.5 Temporary Operation (Depending On Breakdown Status)1 Press the Auto OFF/ON button on the main unit (a “beep” sound is heard) to operate the unit. (Remotecontrol is enable again).2 The unit can be temporarily be used until repaired.Error Code Operation Temporary itemsH23CoolingH27, H28 CoolingEmergency Operationwith limited power58

However, the remotecontrol signal receiving sound is changed from one “beep” to four “beep” sounds.59
