What it means on the road
Uneven cabin temperatures, noisy units and heavy power use are common frustrations with older air conditioning.

Manuals
Our expert's take
Check the power side before anything else. Look at the power supply in the specifications: mains powered units need hook-up or a generator or inverter system big enough to run them, so think about where you usually stay before you choose. Have it fitted by a qualified installer.

Frequently asked questions
What are the main specifications?
Cooling capacity: 1700 W. Heating capacity: 800 W. Weight: 29 kg. Dimensions (L x W x H): 752 x 702 x 225 mm. Recommended vehicle length: Up to 6 metres. The full list is in the Specifications table in the product details.
Will it fit my roof?
Roof air conditioners fit a roof opening of a set size, and roof shape and thickness also matter. Check the dimensions in the specifications and the installation manual, and call us with your vehicle details if you are unsure.
What power does it need?
Check the input voltage and power figures in the specifications. Mains powered units need electric hook-up or a suitably sized generator or inverter system. Call 0330 122 7773 if you would like help planning your power supply.
Should it be professionally fitted?
Yes. We recommend installation by a qualified fitter, as it involves using or cutting a roof opening, sealing it properly and connecting the power supply.
