Frequently Asked Questions
Q: What should I check before switching on the air conditioner?
Make sure the campsite's power supply is fused for at least 650W (230V, 3A), and fully unwind any cable drum to stop it overheating.
Q: How do I switch between cooling modes?
For low-speed cooling, put the control panel switch on 'b' (quiet enough for overnight use, and dehumidifies) or 'c' for high-speed cooling (cools faster).
Q: Can I operate the air conditioner while driving?
Yes, but to protect the compressor while running on the move (e.g. from a generator or voltage transformer), avoid gradients steeper than 8%.
