No real problem with air con units. 90% will work happily with C type breakers but I generally fit D type (saves any potential problems). I assume that the isolator is for external mounting in which case it is required accesible and in close proximity to the external heat exchanger. Check what is required, with regard to individual fusing, for the internal extractor unit and the supply requirement.
