Helpful information CAUTION CAUTION The air filters and your electiric bill. If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted. Turn off the circuit breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire. Operation Tips Do not overcool the room. This is not good for the health and wastes electricity. Clean the air filter regularly. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks. Keep blinds or curtains closed. Do not let direct sunshine enter the room when the air conditioner is in operation. Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. 14 Make sure that the doors and windows are shut tight. Avoid opening doors and windows as much as possible to keep the cool air in the room. Troubleshooting Tips Before you call for service...

It seems that condensate is leaking from the air Conditioner. Air conditioner does not operate for about 3 minutes when restart. Does not cool or heat effectively. The air conditioner operation is noisy. Crack sound is heard. Remote control display is faint, or no display at all. Explanation See page Have you made a mistake in timer operation? 8 On first starting, the indoor unit operates in fifteen seconds. l Has the fuse blown or has the circuit breaker been tripped? l Check power supply for single/reverse phase, voltage imbalance. l Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room. l Condensation occurs when the airflow from the air conditioner cools the warm room air. l This is the protector of the mechanism. l Wait about three minutes and operation will begin. l Is the air filter dirty? See air filter cleaning 12 instructions. l The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down. l Has the setting temperature been set incorrectly? l Are the indoor unit's air inlet or outlet vents obstructed? l For a noise that sounds like water flowing. -This is the sound of freon flowing inside the air conditioner unit. l For a noise that sounds like the compressed air releasing into atmosphere. -This is the sound of the dehumidifying water being processed inside the air conditioning unit. l This sound is generated by the expansion/contraction of the inlet grille, etc. due to changes of temperature. l Has the circuit breaker been tripped? l l NOTE WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT. The indoor side is not water resistant and should not be exposed to excess water. 15 ENGLISH Troubleshooting Tips! Save time and money!
