Frequently Asked Questions
Q: Can I operate the Aventa eco while driving?
Yes, but if running it while driving (from a generator or voltage converter), avoid gradients steeper than 8% - this protects the compressor from damage.
Q: What type of power source is required for the Aventa eco?
The power feeding it must come from a clean sine-wave source (a good-quality voltage converter or generator) and no voltage spikes, for trouble-free running.
Q: How can I cool down the vehicle as quickly as possible?
For faster cooling, set the fan level to high, move the front/rear air distribution to the center position, and set the floor/ceiling air distribution to the ceiling.
