Installation & the rules that apply

This is a portable monobloc. The most regulation-light option by far. No F-gas certified installer is needed because you never break into the refrigerant circuit, no planning permission or permit is triggered since nothing is fixed to the building, and a landlord usually cannot refuse it as there are no permanent alterations. The main constraints are the tenancy or building rules on window-kit appearance and noise nuisance to neighbours.
