Your air conditioner is a durable household appliance. Use it properly and maintain it regularly to guarantee its long life.
| To achieve comfortable and economical use, pay attention to the following tips: |
| 1. Overcooling or overheating consumes excessive energy, so set a proper indoor temperature. If the switch is on "CONT" position, it indicates airflow operation. |
| 2. Clean air filter every two weeks. A blocked filter may lead to narrow airflow and lower rotating efficiency. |
| 3. Adjust a proper airflow direction. Automatic swinging ensures a constant temperature in the room. |
| 4. Use the unit only when necessary. For example, turn it off while sleeping; the unit needs rest. |
| 5. Avoid direct sunshine or hot wind. Shelter windows with curtains and close the door when you leave. |
| 6. Keep heating sources, such as an electric heater, outside of the cooling area while in operation, |
| 7. Shut off power supply before maintenance, and pull out plug. Clean unit with soft, dry cloth. Never use water, which may cause short-circuit. Don’t clean it with gasoline, paint thinner, benzene chemicals or polishing powder, which may corrupt or scrape the surface. |
| 8. Clean air filter regularly. Push filter up and draw it out. Clean with warm water and dry thoroughly; never screw the filter or dry it on fire. After cleaning, reinstall. Do not run unit without filters. |
| 9. After summer, clean indoor and outdoor units completely. First, run the unit in airflow mode for 4-5 hours to keep it dry, then pull out plug and cover unit with dustproof cover. Perform this monthly for best benefit. |
How long can a unit continuously run?
In general, the machine won’t be damaged even after 8-10 days’ operation. In the plant, all products are subject to a continuous running test (over 500 hours or about 20 days). As well, , a compressor can run continuously for 500-2000 hours.
How will I know if the unit has enough Freon?
| 1. Feel: After a period of operation, your skin may feel cool wind. It is normal that the compressor stops occasionally. |
| 2. Measure: Measure the temperature difference between air inlet and outlet of indoor unit. 10?? difference is normal. The larger the difference, the better the operation. |
| 3. Watch: Upon opening the panel of indoor unit after ten minutes’ operation, you may find equal condensing water drops on the evaporator. This is normal. If one half panel is covered with water while another half is dry, then the Freon is not enough. Part frost or ice is abnormal. |
| 4. Touch: Touch the outdoor unit after ten minutes’ operation. There are two copper valves, one connects to a thick copper pipe, and the other connects to a thin copper pipe. The thick valve should be colder than the thin one. Next touch the air outlet; hot wind indicates normal operation. Otherwise, supply Freon. |
| 5. Observe: -After 6-month’s use, check if the joint between indoor pipe and outdoor valve shows oil leakage. If so, supply Freon. |
