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 sauna heater, relay boxes and
other electrical systems or equipment with a fixed mains con-
nection 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.
Read and observe the present installation instructions.
Fire hazard from
overheating
Insufficient ventilation can lead to sauna heater overheating and
fire.
Install air inlets and outlets 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

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 (e.g. laminate or synthetic flooring). Ceram-
ic tiles are recommended as a flooring option.
Water connection If water flows from the water supply and the water level control for
the sauna heater back into the piping system for potable water,
the potable water is contaminated.
Close the shut-off valve if the connection to potable water is not
used for an extended period of time.
Install a non-return valve (backflow preventer).
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.

Damage to health Spending time in a sauna cabin can lead to serious health risks or
even death for persons with health impairments.
Excessive time spent in a heated sauna cabin can lead to overheat-
ing of the body (hyperthermia), which may cause serious health
problems or even death. Hyperthermia occurs when the core tem-
perature of the body exceeds the norm by a few degrees. Symp-
toms 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.
Persons with health impairments who spend time in a sauna
must consult a doctor before entering a sauna cabin.
Warn sauna users by affixing a warning plate. Read the chapter
entitled 4.10 Warning plate, EN-39.
Health risks Floor heating in the sauna cabin results in additional warming of
the legs and can lead to health risks.
Adding essences or other additives for humidification could result
in a health hazard.
Observe the following when using the sauna:
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.
Operating the unit The sauna heater must not be operated by people who have not
received proper training. There is a high risk of injury if the device
for rotating the rock stores is operated by people who have not re-
ceived proper training.
Children must not play with the unit. Cleaning and maintenance
must not be performed by children.
The crank handle must be kept out of the reach of sauna users
and only brought to the device by trained personnel when the
rock stores are to be rotated.
The rock stores must be immersed to the lowest position on the
device to prevent them from rotating.
Children must be supervised to ensure they do not play with
the unit.

General safety instructions
Risk of scalding from
hot steam

Look out for steam and keep a safe distance.
The device should only be operated by people who have re-
ceived proper training.
Bacterial growth in
the water tank
Bacteria may spread in the water inside the water tank.
Replace the water regularly.

Sauna cabin and
heater
The sauna cabin must be constructed with proper material and
built in a professional manner, and the sauna heater must be suit-
ed 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 sauna heaters are used, depending
on their position, an additional safety temperature limiter must
be installed for each additional sauna 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.
The minimum dimensions of the air inlets and outlets can be
found here: 2.4 Technical data, EN-16.
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.
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.
