General safety instructions
Damage to health
Excessive time spent in a heated sauna cabin can lead to overheating of the body (hyper-
thermia), 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 eects of hy-
perthermia 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.
Alcohol, drugs, and medications increase the risk of hyperthermia..
• Do not exceed the maximum recommended time in the sauna.
• Leave the sauna cabin if your body responds abnormally to the heat or if you do not feel
well.
• Avoid alcohol, drugs, and medications when you are using the sauna.

Identification
Intended use
This sauna heater is intended solely for the purpose of heating sauna cabins, together with a suit-
able control unit.
EOS Selection is a oor-standing sauna heater that is suitable for private and commercially used
cabins.
The heater is not suitable for outdoor use !
It must be operated only inside buildings and may not be exposed to environmental
conditions such as extreme humidity and moisture or the possible formation of conden-
sation or corrosive substances in the ambient air, as well as other weather conditions.
Any use beyond this is considered improper use. Proper use also includes compliance with operat-
ing, maintenance and servicing requirements.
The manufacturer is not responsible for unauthorised modications and damages resulting from
these modications; the person modifying the equipment alone shall bear the associated risk.
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 or persons with reduced mental capacity or by persons who
have not been thoroughly instructed in its use.
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 specications and information provided by your sauna retailer.
• The sauna heaters heat the sauna cabin with heated convection air.
• resh air is drawn in through the air inlet. It is warmed and rises (convection) and is then cir-
culated 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 recliner 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 temperature limiter should be mounted ac-
cording to the installation instructions for the control units.
• 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 heat-
ed and before using the sauna.

Installation
Installation
Installation site
• Inner ceiling height of at least 190 cm
• Distance between heater and cabin wall at least 4 cm
• Distance between heater and bench or other ammable materials at least 4 cm
• The required heater power depends on the sauna size and construction. Heater power must suit
the sauna size. See the chapter„Technical Data“.
This chapter describes how to install the sauna heater. Prior to the installation, air inlets and outlets
must be installed in the sauna. It may be necessary to mount additional fans in the inlets/outlets.
All protective lms must be removed from the heater.
NOTICE
Damage due to incorrect mounting location
The heater is not suitable for outdoor use!
• The heater must be operated only inside buildings and may not be exposed to environ-
mental conditions such as extreme humidity and moisture or the possible formation of
condensation or corrosive substances in the ambient air, as well as other weather condi-
tions.
• The heater is not designed to be installed in a niche, under a bench or a sloping roof.
Specications for the sauna cabin
The sauna cabin must be planned and installed according to specications before the sauna heat-
er is installed.
The oor on which the sauna heater stands must be level.
In general, it should be noted that the sauna heater must not be placed on a oor made of easi-
ly ammable material (laminate, ooring made of plastic material, etc.). Ceramic tiles are recom-
mended as a ooring option.
Electrical lines
All electrical installations laid inside the cabin must be heat-resistant silicone cables and must be
suitable for temperatures of at least 170°C.
All lines must be routed in such a way that they are well-protected, e.g. in a cable duct.
If single-core lines are used as connecting cables, they must be protected by a exible metal hose
connected to the protective conductor.

Air inlets and outlets
Fire hazard from overheating
The heater can overheat if the air supply is insucient. Risk of death due to sauna re.
• Ensurethattheairinletsandoutlets providesucientventilation.Installa fan if necessary.
• Sauna may be only switched on after all air inlets and outlets have been opened.
WARNING
Air inlets and outlets must be installed in the sauna cabin to ensure a sucient air circulation and
to prevent the heater from overheating.
The required size of the air inlets and outlets depends on the heater power, see Technical data.
Connection cable
The heater connects via a connection cable to the sauna control unit, and if above certain power
also to the additional power extension unit. The heat-resistant silicone cable is sensitive to me-
chanical damages and be appopriately protected during installation. For this purpose use a cable
duct or a protective pipe from the installation site of the heater up to the control unit. The radius
for laying the cable around a corner should be at least 100 mm (R100).
See the connection diagram for details.
Temperature sensor
The main temperature sensor with the safety overheating limiter must be installed at the place
with the highest expected temperature, which normally means directly above the heater.
The temperature sensor with the overheating limiter fuse is not included in the scope of delivery.
Refer to the separate installation instruction of the sauna control unit for installation details.
If the heating process takes too long time, the common reason is the insucient fresh air supply to
the heater. Sauna should have the air exchange rate of at least 5 volumes per hour.
If, although the air inlet/outlet are properly sized, the heater still lacks the fresh air supply, a fan
(mechanical ventilation) should be installed at the air supply side outside the sauna cabin.
Depending on the location of the heater, the air inlet needs to be installed behind or below the
heater.

General instructions for electrical installation
Ensure that electrical installation is performed in compliance with the standards and legal norms
valid in your country.
If a residual current device (RCD) is installed, ensure that there are no other electrical consumers
not belonging to the sauna system which are fused via this RCD.
If the sauna heater has not been used for an extended period of time, the heater may draw mois-
ture from the ambient air, which, in rare cases, could lead to the RCD to be tripped.This is a physical
process and not a fault on the part of the manufacturer.
In this case, the heater must be heated by a technician under supervision which will bypass the
RCD function. Once the moisture has escaped from the heating elements after approx. 10 minutes,
the RCD can be integrated again in the electric circuit.
If the sauna heater will not be used for an extended period of time, we recommend that you switch
on the heater every 6 weeks so that the heating elements do not accumulate moisture. If, during
commissioning, the RCD is triggered, the electrical installation must be checked again
The electrician is responsible for properly connecting the heaters; thus, the manufacturer does not
assume liability.
Connections
The sauna control unit, the output controller, and the heater must be connected as shown in the
circuit diagrams.
Please observe the installation and operating instructions for the control units and output con-
trollers.
