Fit & Installation
The listed sauna plug and infrared circuit apply to the infrared system. The included traditional heater has its own electrical and installation requirements, so the installer must review both manuals and size the supplies accordingly. Place the freestanding cabin on a solid, dry surface with the specified clearances. This is an indoor sauna; optional covers are sold separately. Follow Finnmark’s operating instructions when selecting or combining heating modes.
