Before turning on a portable air conditioner, it is generally recommended to let it sit upright for at least 24 hours. This waiting period allows the refrigerant and oil in the compressor to settle properly, ensuring optimal performance and preventing potential damage.
During transportation or when the unit has been lying on its side, the refrigerant can move around and create air bubbles. Allowing the air conditioner to sit upright gives these bubbles a chance to dissipate, ensuring the unit operates smoothly and efficiently.
It's important to consult the manufacturer's instructions for your specific model, as recommendations may vary. The user manual should provide guidance on the recommended waiting time before operating the portable air conditioner after transport or when it has been in a position other than upright.
Following the manufacturer's guidelines will help ensure the longevity and proper functioning of your portable air conditioner.
