Prior to Operation

Preparing for Operation

1. Contact an installation specialist for installation.
2. Use a dedicated circuit.

Usage

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.

Cleaning and Maintenance

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

2. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
3. Check that the ground wire is connected correctly. It may be connect to the indoor unit side.

Helpful information

The air filters and your electric 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.

Operation Tips

• 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.
• 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.
