After purchasing a portable air conditioner, it is generally recommended to leave it in the upright position for a minimum of 2-4 hours before using it. However, it's essential to follow the manufacturer's specific guidelines, as they might have different recommendations.
The reason for leaving the portable air conditioner upright after purchase is to allow the refrigerant and compressor oil to settle. During transportation and handling, the air conditioner may have been tilted, which can cause the refrigerant and oil to move around and potentially mix. If the air conditioner is immediately turned on after purchase without allowing the refrigerant and oil to settle, it could lead to compressor damage or reduced cooling efficiency.
By keeping the unit upright for a few hours before operation, you allow time for any displaced refrigerant and oil to flow back into their proper places, ensuring that the air conditioner functions correctly and efficiently. It's a precautionary measure to protect the internal components and maximize the unit's lifespan.
Always refer to the user manual or the manufacturer's instructions for specific guidelines on handling and setting up your portable air conditioner. This will help you ensure the unit operates optimally and stays in good condition throughout its use.
