1General safety instructions
1.1 Safety instructions for assembly and
installation
The installation instructions are intended for qualified person-
nel familiar with the laws and regulations applicable to elec-
trical installations at the installation site. Observe the following
general safety instructions during mounting, configuration
and commissioning of the product.
Risk to life and limb and
risk of fire
Risk to life and limb from electric shock and fire in the event of
improper or faulty electrical connection. This risk remains also
after completion of the installation work.
uThe electrical installation of the heater, power units and
other electrical equipment with fixed mains connection
may only be carried out by a trained electrician of an au-
thorised electrical company.
Ensure compliance with the applicable standards and reg-
ulations for electrical installation.
The system must be completely disconnected from the
mains supply before commencing installation and repair
work.
The housing cover must only be removed by a qualified
electrician.
Fire hazard from
overheating
Insufficient ventilation can lead to the unit overheating and
fire.
uInstall air inlets and outlets in the cabin.
uFollow the safety and installation instructions of the cabin
manufacturer.

General safety instructions
EOS Structure - Installation and Operating Instructions 7
Risk of fire due to sauna
stones
It is possible for hot stones or stone pieces to fall out of the
rock store.
uThe sauna heater may not be placed on a floor made of
easily flammable material (e.g. laminate or synthetic floor-
ing). Ceramic tiles are recommended as a flooring option.
Risk of burns from hot
glass
Glass surfaces in the cabin become hot while the sauna is in
operation.
uWhen installing the cabin, note that the touchable glass
surfaces on the outside of the cabin must not get hotter
than a maximum temperature of 76°C. Attach appropriate
guards if necessary.
Risk of burns from hot
unit
The sauna heater gets hot during operation. Touching the
sauna heater can cause burns.
uMaintain the safety distances.
Sauna cabin and sauna
heater
The sauna cabin must be properly built from suitable material
and the sauna heater must be suitable for the cabin.
uThe sauna heater and control unit may only be used in
sauna cabins made of suitable, low-resin and untreated
material (e.g. Nordic spruce).
uMultiple heaters may be installed in a sauna if the cabin
volume and heater output are compatible. In this case,
depending on the position, an additional safety temperat-
ure limiter must be installed for each additional sauna
heater.
uThe sauna heater is not designed to be installed or set up
in an alcove or under the bench or a roof slope.
uDo not install any electrical sockets in the sauna cabin.
uAir inlets and air outlets must be provided in every sauna
cabin. The air inlets and air outlets can be positioned be-
low or behind the sauna heater. The minimum dimen-
sions of the air inlets and air outlets are given in the tech-
nical data.
uThe air outlet is always installed in the lower part of the
wall, diagonal to the sauna heater. The air inlets and air
outlets must not be closed. Note the instructions of the
sauna cabin supplier.

8 Installation and Operating Instructions - EOS Structure
uUse one of the control units described in the technical
data of these instructions to control the sauna heater. This
control unit is fixed in a suitable place on the external wall
of the cabin. The corresponding sensor housings are fixed
inside the sauna cabin, refer to the control unit installa-
tion instructions.
uThe cabin lighting must be safe for sauna cabin use and
installed in such a way that it can be used safely in a sauna
cabin. Make sure that the standards and regulations ap-
plicable in the respective country are met.
uThe cabin door must open outwards and must not have a
lock that cannot be opened in the case of failure. We re-
commend magnetic latches or spring catches.
1.2 Operator instruction
The operator of the sauna cabin must be instructed in the fol-
lowing general safety instructions during commissioning. The
operator must be given a copy of these instructions.
Risk of electric shock A risk to life and limb from electric shock and fire arises in the
event of improper repair work. This risk remains also after work
is completed.
uRepairs and installations must only be performed by a
trained electrician.
uThe system must be disconnected and removed entirely
from the mains supply before commencing repair work.
uThe housing cover must only be removed by a qualified
electrician.
uUse only original spare parts from the manufacturer.

Fire hazard Objects placed on the heater or protective grilles can easily be
ignited and cause fires.
uDo not remove heater protection (sheet metal guard).
uDo not place objects on the heater.
uFill the rock store as directed.
uInspect the sauna cabin each time before switching on.
uIf you switch on the sauna heater using a pre-set timer or
a remote control, use a cover protection system for the
heater or install a suitable safety device.
Health risks Spending time in a sauna cabin can lead to serious health risks
or even death for persons with health impairments.
uPersons with health impairments must consult a doctor
before entering a sauna cabin.
Damage to health Excessive time spent in a heated sauna cabin can lead to over-
heating of the body (hyperthermia), which may cause serious
health problems and even death. Hyperthermia occurs 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 effects 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 physic-
ally leave the room, unconsciousness.
Alcohol, drugs, and medications increase the risk of hyperther-
mia.
uDo not exceed the usual sauna times.
Leave the sauna cabin if your body reacts unusually to the
heat or if you feel unwell.
Do not drink alcohol, take drugs or medicines before a
sauna session.
