1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling

2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,

leading to possible electric shock.

3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates

at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

1. Being exposed to direct airflow for an extended period of time could be hazardous to your health.

Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or

other heating devices.

3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision

devices, food, pets, plants, and art objects). Such usage could damage the items.

1. Contact an installation specialist for installation.

2. Use a dedicated circuit.

Maintenance and Service10 Indoor Unit Maintenance and Service CAUTION Operation Tips Helpful information 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. When it is not going to be used for a long time. When the air conditioner is to be used again. Operate the air conditioner at the following settings for 2 to 3 hours.

• Type of operation: Fan operation mode.

This will dry out the internal mechanisms. Turn off the breaker. Clean the air filter and install it in the indoor unit. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. Check that the ground wire is connected correctly. It may be connect to the indoor unit side. Do not overcool the room. This is not good for the health and wastes electricity

Keep blinds or curtains closed. Do not let direct sunshine enter the room when the air conditioner is in operation. Keep the room temperature uniform. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room. 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. 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. Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. When the air conditioner is not going to be used for a long time Turn off the breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire.Owner’s Manual 11 ENGLISH Maintenance and Service Before you call for service... Check the following points before requesting repairs or service....
