The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature. During SUPER QUIET operation, the fan will operate at very low speed. In the monitor AUTO operation, the fan will operate at very low speed. During Heating operation, water may be produced from the outdoor unit due to Automatic Defrosting operation. After approximately 400 hours of Air Cleaning Mode use, the AIR CLEAN Indicator Lamp will begin to flash slowly (as shown in the figure). When this occurs, please stop the system, remove the mains socket and carry out maintenance on the dust collecting unit's air filter. After approximately 500 hours of Air Cleaning Mode use, the AIR CLEAN Indicator Lamp will begin to flash quickly (as shown in the figure). At this point, Air Cleaning will stop functioning. Please stop the system, remove the mains socket and carry out maintenance on the dust collecting unit's air filter.

Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to disconnect the Power Supply Plug or turn off your circuit breaker to ensure that power is completely off. Before requesting service, perform the following checks: En-17 TROUBLESHOOTING Symptom Doesn’t operate at all: Poor Cooling performance: The unit operates differently from the Remote Control Unit’s setting: See Page — 8 - 9 — 5 4 Items to check Is the Power Supply Plug disconnected its outlet? Has there been a power failure? Has a fuse blown out, or a circuit breaker been tripped? Is the timer operating? Is the Air Filter dirty? Air the air conditioner’s intake grille or outlet port blocked? Did you adjust the room temperature settings (thermostat) correctly? Is there a window or door open? In the case of Cooling operation, is a window allowing bright sunlight to enter? (Close the curtains.) In the case of Cooling operation, are there heating apparatus and computers inside the room, or are there too many people in the room? Is the unit set for SUPER QUIET operation? Are the Remote Control Unit’s batteries dead? Are the Remote Control Unit’s batteries loaded properly? OPERATING TIPS If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp (Fig. 3 5) and the TIMER Indicator Lamp (Fig. 3 6) flashes, immediately stop operation, disconnect the Power Supply Plug (Fig. 1 F), and consult authorized service personnel. Operation and Performance Heating Performance This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating performance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance. Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated. Microcomputer-controlled Automatic Defrosting When using the Heating mode under conditions of low outdoor temperature and high humidity, frost may form on the outdoor unit, resulting in reduced operating performance. In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for about 7-15 minutes). During Automatic Defrosting operation, the OPERATION Indicator Lamp (red) will flash. AUTO Restart In Event of Power Interruption The air conditioner power has been interrupted by a power failure. The air conditioner will then restart automatically in its previous mode when the power is restored. Operated by setting before the power failure. If a power failure occurs during TIMER operation, the timer will be reset and the unit will begin (or stop) operation at the new time setting. In the event that this kind of timer fault occurs the TIMER Indicator Lamp will flash (see Page. 3). Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily disconnect the Power Supply Plug, reconnect it, and then use the Remote Control Unit to resume operation. CHECK ONCE MORE En-18 OPERATING TIPS Dry Mode About 14 °F to 115 °F About 64 °F to 90 °F Outdoor temperature Indoor temperature Cooling Mode About 14 °F to 115 °F About 64 °F to 90 °F Heating Mode About 5 °F to 75 °F About 86 °F or less Temperature and Humidity Range If the air conditioner is used ...
