Frequently Asked Questions
Q: What should I check before switching on the air conditioner?
Ensure that the fuse system for the power supply at the campsite is sufficient for 650 W (230 V) (at least 3 A) and that the cable drum is fully unwound to prevent overheating.
Q: How do I switch between cooling modes?
Move the control panel switch to 'b' for cooling at low fan speed (suitable for quiet night operation and dehumidification) or 'c' for cooling at high fan speed (rapid cooling).
Q: Can I operate the air conditioner while driving?
Yes, but to avoid damage to the compressor when operating during transit (e.g., with a generator or voltage transformer), do not attempt uphill or downhill gradients of more than 8%.
