ner, and the output of the sauna heater must be suited for the cabin.
The sauna heater may only be used in sauna cabins made of suitable, low-resin
and untreated material (e.g. Nordic spruce).The control unit must not be used in
the cabin.
Multiple heaters may be installed in one sauna if the heater output can properly
supply the cabin volume. In this case, depending on the position, an additional
safety temperature limiter must be installed for each additional heater.
The sauna heater is not designed to be installed or set up in an alcove or under a
bench or sloping roof unless the sauna heater is specically designed and ap-
proved for this type of installation.
Receptacles may not be installed inside the sauna cabin.
Each sauna cabin must have air inlets and outlets.The air inlets and outlets may
be installed from below or from behind the heater.The minimum dimensions of

General safety instructions
when the core temperature of the body exceeds the norm by a few degrees.
Symptoms of hyperthermia include fever, dizziness, lethargy, sleepiness, and fainting.
Side eects of hyperthermia include perception disorders, inability to recognize the need
to leave the room, inability to identify imminent danger, harm to the foetus in the case of
pregnant women, inability to physically leave the room and unconsciousness.

2.4 Foreseeable misuse
The following are considered instances of foreseeable misuse:
The unit is operated without knowledge of or compliance with the safety
instructions.
The requirements for operation, servicing and maintenance are not met.
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 re-
duced 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 lled
as directed.
The heater power does not match the sauna volume.
The unit is operated with insucient air supply or exhaust air.
2.5 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 syn-
chronized.
Observe the specications and information provided by your sauna retailer.
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 (convection) 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 which
temperatures of approx. 110°C are achieved directly below the ceiling. These
temperatures drop to approx. 30–40°C in the cabin along the oor. Therefore,
it is not unusual that if the temperature sensor above the heater reads 110°C,
the thermometer that is mounted approx. 20– 25 cm below the cabin ceiling
on the sauna wall reads only 85°C. When the max. temperature is set for the
area around the upper sauna bench, the bathing temperature is typically
between 80°C and 90°C.
Please note that the highest temperatures in the cabin are always above the
sauna heater and that is where the temperature sensor and safety tempera-
ture limiter should be mounted according to the installation instructions.
The rst time the cabin is heated, you may notice a slight odour resulting from
the evaporation of consumables used in the manufacturing processes. Air out
your cabin once it has been heated and before using the sauna.
