3.2. Connecting the sauna heater to the mains
The sauna heater must be connected to the mains by a qualified electrician and in compliance with current
regulations. The electric sauna heater is semi-permanently connected to the mains. Use H07RN-F (60245 IEC 66)
cables, or alternatively an equivalent or higher quality cable. Other cables in the heater (to the signal lamp and the
electric heating's cross connector) must also be of an equivalent type. PVC-insulated cables must not be used as
connection cables.
A multi pole cable (e.g. 7-pole) can also be used as a connecting cable when 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 main fuse.
The junction box on the sauna wall should be located within the minimum safety clearance specified for the sauna
heater. The maximum height for the junction box is 500 mm from the floor (see illustration 4 on page 13). If the
junction box is located more than 500 mm from the heater, the maximum height is 1,000 mm from the floor.
The sauna heater's insulation resistance: Moisture can build up on the sauna heater's fuses during storage. This
may cause current leakage. The moisture is dispelled when the sauna heater has been heated up a few times. Do
not connect the heater's power outlet to an earth fault breaker.
Applicable electrical safety regulations must be followed when installing the heater.

3.3. Installation of control unit and sensor
The control unit has been connected electrically by a cable to the sauna heater. The control unit must be installed
outside the sauna room.
The sensor is mounted to the sauna wall, directly on the center line of the sauna heater, 40 mm from the ceiling. (see
illustration 3 on page 12)
NOTE!
If the wall on which the sensor is to be installed is made of highly heat insulating material (e.g. concrete, brick etc.) or
if the wall is made of toughened glass, the sensor can be installed directly above the heater (on the heater's center
line viewed from both the front and from the side (see illustration 2 on page 12)
Deviations from the fitting dimensions specified can lead to a risk of fire!
The temperature limiter in the sensor interrupts the heater's temperature output if the heater's temperature increases
to such an extent that it represents a danger for the sauna's wooden parts. When the temperature has fallen, the
limiter can be reset by pressing the reset button.
Before resetting you must always investigate why the temperature limiter was triggered!
