Foreseeable misuse
The following are considered instances of foreseeable misuse:
The unit is operated without knowledge of or compliance with the
safety instructions.
Operating, service and maintenance requirements are not observed.
The unit is operated by children under 8 years of age.
The unit is operated by children 8 years of age or older, or persons with
reduced mental capacity who have not been thoroughly instructed in
its use.
The unit is operated without sauna stones or with a rock store that is not
filled as directed.
The heater output does not match the cabin volume.
The unit is operated with insufficient air supply or exhaust air.
General instructions
Please note that an optimal sauna climate can be achieved only if the
cabin with its air inlets and outlets, the sauna heater, and the control
unit are synchronized.
Observe the specifications and information provided by your sauna
retailer.
Please note that the highest temperatures in the cabin are always above
the sauna heater and that is where the temperature sensor and safety
temperature limiter should be mounted according to the installation
instructions for the control units.
The sauna heaters heat the sauna cabin with heated convection air.
Fresh air is drawn in through the air inlet. It is warmed and rises (convec-
tion) and is then circulated in the cabin. Some of the used air is pushed
out of the cabin through the cabin's air outlet. This creates a typical
sauna climate in your sauna.
Note that there is a drop in temperature from the ceiling to the floor of
the sauna cabin. Temperatures are measured and regulated based on
the ceiling values.Thermometers placed below the ceiling will therefore
display lower temperatures. When the max. temperature is set for the
area around the upper sauna bench, the bathing temperature is typi-
cally between 80°C and 90°C.
The first time the cabin is heated, you may notice a slight odour result-
ing from the evaporation of consumables used in the manufacturing
processes. Air out your cabin once it has been heated and before using
the sauna.

The heater can overheat if the air supply is insufficient. There is a
risk of death due to fire.
Ensure that the air inlets and outlets provide sufficient ventila-
tion. Install a fan if necessary.
Commission the cabin only after all air inlets and outlets have
been opened.
If the heating process takes a long time, the underlying reason is that the
heater receives insufficient air. A minimum of 5 times the cabin volume of
air per hour must be exchanged.
If, despite compliance with dimensions, there is still not enough fresh air to
reach the heater, a fan must be installed at the air inlet outside of the cabin.
