on page 11. The minimum and maximum volumes must not be exceeded.
2. The sauna room height must be a min. of 1900 mm.

to the sauna room's volume.
4. Check page 12 Table 2 for a suitable fuse size (A) and the correct diameter of the power supply cable (mm²) for the sauna
heater in question.
5. Conform to the specified safe clearance around the sauna heater. Please refer to table 1 on page 11.
6. There should be enough room around the sauna heater for maintenance purposes. Also a doorway can be considered as a
maintenance area.
3.2. Installation
Follow the safety clearance specifications on page 11 when installing the sauna heater. A thin panel is not a suitable mounting
base; the mounting base must be reinforced with timber behind the panel. The minimum clearances specified on page 11 must
be followed even if the sauna room wall materials are incombustible.
Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they may cause a
fire hazard.
Install the sauna heater so that the sign and the warnings can be read even after the installation.
The control panels are installed outside the sauna room with the exception of the Midi controller which is installed on the wall
beside the sauna heater. Refer to more detailed installation instructions in the installation and operation guide of the control
panel.
Only a single sauna heater is allowed per sauna room
