Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage currents. The
moisture will be gone after a few heating sessions. Do not connect the heater power supply through a ground fault interrupter.
However, adhere to the effective electrical safety regulation when installing the sauna heater.
3.5. Electric heating toggle
The electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked 55) for controlling the electric heating toggle. Connector 55 and the heating elements
are simultaneously live (230V).
3.6. Sauna heater safety clearances
NOTE! The thermostat is installed at a distance of 40mm from the ceiling in the middle of the sauna heater.
