1.2 Mounting and electrical installation
These installation instructions are intended for qualified person-
nel familiar with the laws and regulations applicable to electrical
installations at the installation site. Observe the following general
safety instructions during mounting, configuration and commis-
sioning 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 im-
proper or faulty electrical connection. This risk also applies follow-
ing completion of the installation work.
The electrical installation of the heater, vaporiser, relay boxes
and other electrical systems or equipment with a fixed mains
connection must only be performed by a trained electrician
from an authorised electrical company.
Ensure compliance with the standards and regulations for elec-
trical installation in your country.
The system must be disconnected and removed entirely from
the mains supply before commencing installation and repair
work.
The housing cover must only be removed by a specialist.
Fire hazard from
overheating
Insufficient ventilation can lead to device overheating and fire.
Install the air inlet and outlet in the cabin.
Observe the cabin manufacturer's safety and installation in-
structions.
Risk of burns from
hot glass
Glass surfaces in the cabin become hot while the sauna is in oper-
ation.
When installing the cabin, ensure that the touchable glass sur-
faces on the outside of the cabin may reach a maximum tem-
perature of 76°C. Appropriate protection may need to be
installed if required.
Risk of burns from
hot unit
During operation, the sauna heater may become hot and, if
touched, could cause burns.
Maintain a safe distance.

General safety instructions
1.3 Operator instruction
The operator of the sauna cabin must be instructed in the general
safety instructions during commissioning. The operator must be
given a copy of the operating 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 also applies after work is com-
pleted.
The housing cover must only be removed by a specialist.
Repairs and installations must only be performed by a trained
specialist.
The system must be disconnected and removed entirely from
the mains supply before commencing repair work.
Use only original spare parts from the manufacturer.
Fire hazard Objects placed on the sauna heaters can easily be ignited and
cause fires.
Do not place objects on the sauna heater.
Fill the rock store as directed.
If you switch on the heater using pre-set timers or a remote con-
trol, attach a protective cover to the heater or install a suitable
safety device.
Inspect the sauna cabin prior to each recommissioning and en-
sure that no towels, cleaning agents or other objects are lying
on the sauna heater or vaporiser.
Risk of fire due to
substances in holder
The holder must not be used if the heater is operated without the
vaporiser function (Finnish sauna mode). Substances in the holder
pose a risk of fire because they can easily be ignited.
Never place herbs or similar substances/objects in the holder if
the heater is being operated without the vaporiser function.
Observe the manufacturer's specifications when adding sauna
essences to the water.
Never leave herbal sachets in the holder if the system has a con-
trol unit with a post-heating time option; they could dry quickly
and catch fire.

Risk of fire due to
sauna stones
It is possible for hot stones or stone pieces to fall out of the rock
store.
The sauna heater may not be placed on a floor made of easily
flammable material (laminate or synthetic flooring, etc.). Ce-
ramic tiles are recommended as a flooring option.
Risk of scalding from
hot steam
There is a risk of scalding from hot steam at the steam emission
outlet when using the vaporiser (Herkules XL S120 Vapor only).
The steam escapes from the long side of the holder.
Add essences and herbs to the holder only from the front.
Health risks Spending time in a sauna cabin can lead to serious health risks or
even death for persons with health impairments.
Persons with health impairments who spend time in a sauna
must consult a doctor before entering a sauna cabin.
Damage to health Excessive time spent in a heated sauna cabin can lead to overheat-
ing 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 per-
ception 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.
Floor heating in the sauna cabin results in additional warming
of the legs and can lead to health risks.
Water connection Prevent water from flowing from the water supply and the box for
the heater's water level control (Herkules XL S120 Vapor only)
back into the piping system for potable water.
Close the shut-off valve if the connection to potable water is not
used for an extended period of time.

General safety instructions
Water lime content Lime deposits can impact the ability of the vaporiser to function
properly (Herkules XL S120 Vapor only).
If the water has a lime content of more than 1.3 millimole of cal-
cium oxide per litre (hardness class I or hardness levels 1–7 in
Germany), we recommend installing a decalcification system. If
a decalcification system is not installed, you must manually des-
cale the vaporiser regularly. The higher the lime content in the
water used, the more often the vaporiser must be descaled.
Operating the unit This unit may be used by children 8 years or older and by persons
with reduced physical, sensory or mental abilities or persons with
no experience or knowledge of the unit, if they are under supervi-
sion or have been instructed in how to safely use the unit and they
understand the associated risks. Children must not play with the
unit. Cleaning and maintenance must not be performed by chil-
dren.
Children must be supervised to ensure they do not play with
the unit.

Sauna cabin and
heater
The sauna cabin must be constructed with proper material and
built in a professional manner, and the heater must be suited for
the cabin.
The sauna heater may be installed only in sauna cabins made
from suitable, low-resin, and untreated material, e.g. Nordic
spruce or other materials suitable for sauna construction.
One or more than one sauna heater may be installed in a sauna.
The heater output must be able to accommodate the cabin vol-
ume in all cases. If multiple heaters are used, depending on
their 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 specifically designed and approved for this type of installa-
tion.
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 floor. The minimum dimensions
of the air inlets and outlets can be found here: 2.4 Technical
data, 15.
The exhaust openings are always installed in the lower part of
the wall diagonal to the sauna heater. The supply and exhaust
openings must not be closed. Please observe the instructions
provided by your sauna cabin manufacturer.
Use one of the control units listed below to check and control
the sauna heater. This control unit is fixed to a suitable location
on the cabin's external wall, and the corresponding sensor
housings according to the installation instructions that accom-
pany the control units inside the sauna cabin.
The cabin lighting must be safe for sauna cabin use and in-
stalled in such a way that it can be used safely in a sauna cabin.
Ensure that the heater is installed in compliance with the stand-
ards and legal norms valid in your country. In CENELEC member
states, the cabin lighting must be “protected from splash water”
as defined in DIN EN VDE 0100 T 703. Only one sauna light with
a maximum of 40 W may be installed with this sauna heater.
The cabin must not have a locking device that cannot be un-
locked as needed. We recommend magnetic or spring locks.
