Please advise me of how to check the air conditioner before use.
Try this
1. Unplug the power cord, and remove surrounding obstacles.
2. Remove the filter, and brush dusts off from the filter with a vacuum cleaner, or clean it with water using neutral detergent, and then leave it at a shady place to dry.
3. Use the product with the power cord turned to Cooling position.
If the product does not turn on, plug another electric device in the outlet to check if power is supplied.
If surrounding temperature is below 18℃, cooling air is not supplied.
