Frequently Asked Questions
Q: Can I operate the Aventa air conditioner using an inverter or generator?
Yes, but the power source must provide a pure sine wave voltage curve (230 V AC, 50 Hz) without voltage spikes, and have a recommended power output of at least 2000 W.
Q: What is the maximum slope the vehicle can be parked on while operating the AC?
The vehicle must not be parked on an incline greater than 8% (approx. 4.5°) to ensure proper compressor lubrication and prevent condensate drainage issues.
Q: How do I pair the air conditioning unit with its remote?
Put batteries in the remote, then press the air distributor's pairing button - it'll start flashing. Next, press the remote's own pairing button; the air distributor's button will light solidly for 10 seconds once pairing is complete.
