ner, and the heater must be suited for the cabin.
Sauna heaters and control units may only be used in sauna cabins made of suitable,
low-resin and untreated material (e.g. Nordic spruce).
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 approved
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 below or behind the sauna heater, approx. 5 to 10 cm above the oor. The
minimum dimensions of the air inlets and outlets can be found here:Technical Data,
air inlets and outlets.

before entering a sauna cabin.
►Equipment damage due to overuse
If the cabin is used commercially, the heating time must be set so that the heater switches
o automatically after a specic period of time.
If the heating does not switch o automatically after a dened heating period, cabin
use must be supervised at all times.
Inspect the cabin before each use.
►Damage to health
Excessive time spent in a heated sauna cabin can lead to overheating of the body (hyperther-
mia), 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 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.
Alcohol, drugs, and medications increase the risk of hyperthermia.

Identication
2.5 Intended use
This heater is intended solely for the purpose of heating sauna cabins, together with a suitable
control unit and two relay boxes. EOS Goliath HD is a free-standing heater that is suitable for com-
mercially used cabins.
The heater is not suitable for outdoor use.
It must be operated only in sauna cabins and may not be exposed to environmental 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 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 unauthor-
ised modications and damages resulting from these modications; the person modifying the
equipment alone shall bear the associated risk.
2.6 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.
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.

12
EN Identication
2.7 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.
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 (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 your sauna.
Note that there is a drop in temperature from the ceiling to the oor 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
typically between 80°C and 90°C.
The rst time the cabin is heated, you may notice a slight odour resulting from the evap-
oration of consumables used in the manufacturing processes. Air out your cabin once it
has been heated and before using the sauna.

Electrical installation
5. Electrical installation
This chapter describes how to connect the EOS Goliath HD to a sauna control unit and to a power
extension unit.
Ensure that electrical installation is performed in compliance with the standards and legal norms
valid in your country..
Following norms must be observed by the installation of sauna heating appliances:
IEC 60364-7-703 bzw. DIN VDE 0100 Teil 703
This standard states in its current edition under amendments paragraph 703.412.05 as follows:
“The additional protection must be provided for all current circuits of the sauna by one or more
fault current protection devices (RCDs) with a rated dierential current not exceeding 30 mA, ex-
cept for sauna heaters.”
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.
5.2 Heating time limitation
5.1 General instructions for electrical installation
►Heating time limitation operation principle
All sauna heaters, except for those installed in public saunas, and which must be operated under
the supervision of sta, must be equipped with a timer that complies with IEC and EN standards,
which limits the operating time for safety reasons. This timer is typically already integrated in all
EOS sauna control units.
The operation time of a public sauna must be limited so that the heating elements are
without power for a minimum of 6 consecutive hours within a 24 hours before an automat-
ic restart can be made.
Units used in private saunas must be limited to an operating time of 6 hours, and an auto-
matic restart is not permitted.

6. Installation
This chapter describes how to install the Goliath HD sauna heater. Prior to installing the unit, air
inlets and outlets must be installed in the cabin. It may be necessary to mount additional fans in
the inlets/outlets. All protective lms must be removed.
6.1 Requirements for the sauna cabin
The cabin must be planned and installed according to specications before the heater is installed.
All electrical installations laid inside the cabin must be suitable for a temperature 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
that is connected to the protective conductor.
In general, it should be noted that the sauna heater must not be set on a oor made of highly
ammable material such as laminate, ooring made of plastic material, etc. Ceramic tiles are rec-
ommended as a ooring option. Floor heating in the sauna cabin increases the temperature of the
oor’s surface temperature.
►Installation site
Ceiling height of at least 2,10 m
Distance between heater’s top and sauna ceiling at least 127 cm.
Distance between heater and cabin wall at least 8 cm
Distance between heater and bench at least 8 cm
The installation height of the safety guard must not be higher than the heater’s top.
The required heater’s power depends on the sauna volume. See chapter 4. Technical Data.
HINWEIS
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
environmental 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 conditions.
The heater is not designed to be installed or set up in an alcove or under a bench or
sloping roof.
