I have been asked if I can find an instruction manual for a "Challenge 12,000 BTU Portable Air Conditioner". All I can determine is that these only seem to be sold by Argos but can't find the actual manufacturer or a user guide. It is possible that they are rebadged. Any help gratefully received.
I have a similar one that I use in my outdoor store to stop the cardboard stuff going mouldy. Set the fan to run at about half speed and the humidity control about half way, also don't forget to empty the tank daily - the amount of water it can remove is surprising.
