Air outlet Long-life filter Removes dust and foreign matter from air coming in through the grille (Recommended cleaning interval : Approx, every,00 operating hours) Up/down guide vanes Change the direction of airflow from the vertical blower. Intake grille Air intake Remote controller Once the controls are set, the same operation mode can be repeated by simply pressing the /OFF button. Operation buttons Set Temperature buttons /OFF button own Up Fan Speed button Timer Menu button (Monitor/Set button) Mode button (Return button) Filter button (<Enter> button) TEMP. /OFF Test Run button Set Time buttons Check button (Clear button) Back MENU /OFF FILTER Ahead Timer On/Off button (Set ay button) BACK PAR-MAA MITOR/SET AY CLOCK OPERATI CHECK TEST CLEAR Airflow Up/own button Louver button ( Operation button) Opening the door To return operation number Ventilation button ( Operation button) To go to next operation number

4 isplay For purposes of this explanation, all parts of the display are shown as lit. uring actual operation, only the relevant items will be lit. Identifies the current operation Shows the operating mode, etc. * Multilanguage display is supported. ay-of-week Shows the current day of the week. Time/Timer isplay Shows the current time, unless the simple or Auto Off timer is set. If the simple or Auto Off timer is set, shows the time remaining. Sensor indication isplayed when the remote controller sensor is used. Locked indicator Indicates that remote controller buttons have been locked. Clean The Filter indicator Comes on when it is time to clean the filter. Centrally Controlled indicator Indicates that operation of the remote controller has been prohibited by a master controller. Timer Is Off indicator Indicates that the timer is off. Temperature Setting Shows the target temperature. F C TIME SUN M TUE WE THU FRI SAT TIMER Hr AFTER AFTER OFF ERROR COE F C LYHr. Up/own Air irection indicator The indicator shows the direction of the outcoming airflow. One Hour Only indicator isplayed if the airflow is set to Low and downward during COOL or RY mode. (Operation varies according to model.) The indicator goes off after one hour when the airflow direction also changes. FUNCTI FILTER WEEKLY SIMPLE AUTO OFF Room Temperature display Shows the room temperature. Louver display Indicates the action of the swing louver. oes not appear if the louver is stationary. (Power On indicator) Indicates that the power is on. Timer indicators The indicator comes on if the corresponding timer is set. Fan Speed indicator Shows the selected fan speed. Ventilation indicator Appears when the unit is running in Ventilation mode. Caution Only the Power on indicator lights when the unit is stopped and power supplied to the unit. If you press a button for a feature that is not installed at the indoor unit, the remote controller will display the Not Available message. If you are using the remote controller to drive multiple indoor units, this message will appear only if the feature is not present at the parent unit. When power is turned for the first time, it is normal that PLEASE WAIT is displayed on the room temperature indication (For max. minutes). Please wait until this PLEASE WAIT indication disappear then start the operation.

[Emergency operation procedure].when the indoor unit microcomputer has failed, but all other components work properly, if you set the switch(swe,sw)on the indoor control board, the indoor unit will begin Emergency Operation..When you activate emergency operation of the cooling or heating, you have to set the switch(swe)and switch(sw)on indoor controller. SWE: Indoor fan is running high speed. rain-up machine(optional)is working. SW-: Emergency operation of cooling mode. SW-,: Emergency operation of heating mode..before you activate emergency operation, check the following points: Emergency operation cannot be activated when: The outdoor unit malfunctions. The indoor fan malfunctions. Emergency operation becomes continuous only by switching the power source on / off. / OFF on the remote control or temperature control etc. does not function. Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of the heating is activated, because it will start to blow cold air. Emergency cooling should be limited to 0 hours maximum (The indoor unit heat exchanger may freeze). After emergency operation has been deactivated, set the switches etc. to their original positions. Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position. 8

59 0-. POWER OUTAE AUTOMATIC RECOVERY OPERATI Whenever a power outage or switching of the power supply causes the power supply of an operating air conditioner to go from OFF to, this function will automatically restore the operation of the air conditioner to its previous operating mode. w If the power is turned from OFF to when the air conditioner is not in operation, the air conditioner will not automatically be turned on. However, the timer operation will be cancelled if the air conditioner is in timer operation (including when the unit is waiting for its start time). Setting for timer operation must be performed once again. If there is a momentary power outage of less than one second while the air conditioner is in operation, there may not be a clear determination of whether or not there was a power failure. When it has been determined that there has been a power failure, recovery will take approximately four minutes after the power is restored. Please wait. (Once "PLEASE WAIT" has appeared on the display, a protection system will operate to prevent the unit from restarting for three minutes.) When it has been determined that there has been no power failure, operation will continue as is. Settings can be made by function selections from the remote controller. When there is group control, selection of all refrigerants is required. 0-. INIVIUAL CTROL OPERATI FROM A SEPARATE ROOM By simply centralizing the remote controllers installed in each room in a separate control room, individual control or centralized monitoring of the air conditioners in each room can be attained.

COMBINE REMOTE/LOCAL CTROL Operation/remote controller prohibit/ stop can be controlled from a remote location by routing the remote stop/start adapter (PAC-SERA-E sold separately) through the relay box installed on site. When this remote control is cancelled, the local remote controller can be used for operating and stopping the air conditioner.. Basic system wiring Use the remote start/stop adapter (PAC-SERA-E) and connect the "Start/Stop Circuit From Remote Location" that comes from the relay box and remote/local selection switch and connect it to the CN connector on the printed circuit board for the indoor unit <Points of precaution> Match the rated power supply voltage of the remote/local selection switch and relay (X) with the power supply for the controller. When performing group control of multiple outdoor unit using a timer, be sure to arrange the timer so that all units do not start at the same time. If this is not performed, all of the units will start at one time creating an over current that will cause the circuit breaker to operate. An on-delay system is one that includes specifications for operating a limited time when an on signal is received and has a temporary off timer for recovery operations. Use a connecting relay when the wiring length exceeds 0 meters, such as when performing remote wiring. If this is not provided, abnormal operation will occur.

Contact may cause malfunctioning. (Separate by cm or more.) 0-. OBTAININ HUMIIFIER SINAL The humidifier signal that is linked to the AC heating operation (indoor unit ventilator) can be obtained by connecting the adapter for the humidifier signal to connector CN on the printed circuit for the indoor unit and wiring it to the humidifier unit via the on-site relay box. There is no output when the thermostat is off, during heating preparation and during defrosting.
