2.10 Main connection
The sauna heater must be connected to the mains by a qualified electrician and in compliance with current
regulations. Sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66)
cables or a corresponding type. Other output cables (signal lamp, electric heating toggle) must also adhere to
these recommendations. Do not use PVC insulated cable as a connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control
current fuse, the diameter of all cables must be the same, i.e. in accordance with the front fuse.
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the
sauna heater. The maximum height for the connection box is 500mm from the floor.
If the connection box is located at 500mm distance from the heater, the maximum height is 1000mm from the
floor. (Image 4 on page 10: Location for the connecting box).
Sauna heater insulation resistance: The sauna heater heating elements may absorb moisture from air, e.g.
during storage. This may cause bleeder currents. The moisture will be gone after a few heating sessions. Do
not connect the heater power supply through a ground fault interrupter.
However, always adhere to the effective electrical safety regulation when installing the sauna heater.
2.11 Electric heating toggle
Electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked N - 55) for controlling the electric heating toggle. Connectors N - 55
and the heating elements are simultaneously live (230V). The sauna heater thermostat also controls the heat-
ing toggle. In other words, home heating turns on once the sauna thermostat cuts power off the sauna heater.

1. Recommended location for the connection box
2. Silumin box recommended in this area.
3. This area should be avoided. Always use a silumin box.
In other areas, use a heat-resisting box (T 125 °C) and heat-resisting cables (T 170 °C). The connection box
must be clear of obstacles. When installing the connection box to zones 2 or 3, refer to the instructions and
regulations of the local energy supplier.
