Correct connection of your Narvi electrical sauna heater in the UK
The installation and maintenance of your new Narvi electrical sauna heater must be done by a certified electrician and the electricity supply must be isolated and/or switched off from the fuse panel prior to any installation or servicing work. In accordance with European standard IEC 60364-7-703 part 703.412.5 an electrical sauna heater does not have to be connected through a Residual Current Device (RCD). This is also in accordance with BS7671:2018 part 703.411.3.3.
For reliable operation of the electric sauna heater, Narvi strongly recommends that the power supply should not be connected through a Residual Current Device (RCD). Other electrical devices in a sauna room should be connected through a Residual Current Device (RCD). Finally, the power supply cable must comply with BS7671:2018 and the instruction manual of the product and local electrical regulations must be followed.
