EN General safety instructions
1.1 Mounting and electrical installation
These installation instructions are intended for qualied personnel familiar with the
laws and regulations applicable to electrical installations at the installation site. Ob-
serve the following general safety instructions during mounting, conguration and
commissioning of the product.
►Risk to life and limb and risk of re
Risk to life and limb from electric shock and re in the event of improper or faulty electrical
connection. This risk remains also after completion of the installation work.
The electrical installation of the heater, relay boxes and other electrical systems
or equipment with a xed mains connection must only be performed by a trained
electrician from an authorised electrical company.
Ensure compliance with the applicable standards and regulations for electrical
installation.
The system must be completely disconnected from the mains supply before com-
mencing installation and repair work.
The housing cover must only be removed by a specialist.
►Fire hazard from overheating
Insucient ventilation can lead to device overheating and re.
Install air inlets and outlets in the cabin.
Observe the cabin manufacturer’s safety and installation instructions.
►Risk of re 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 oor made of easily ammable material
(e.g. laminate or synthetic ooring). Ceramic tiles are recommended as a ooring
option.
►Risk of burns from hot glass
Glass surfaces in the cabin become hot while the sauna is in operation.
When installing the cabin, ensure that the touchable glass surfaces on the outside of

35
General safety instructions
the cabin may reach a maximum temperature 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.
►Sauna cabin and sauna heater
The sauna cabin must be constructed with proper material and built in a professional man-
ner, and the output of the sauna heater must be suited for the cabin.
The sauna heater may only be used in sauna cabins made of suitable, low-resin and
untreated material (e.g. Nordic spruce).The control unit must not be used in the
cabin.
Multiple heaters may be installed in one sauna if the heater output can properly sup-
ply 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 from below or from behind the heater.The minimum dimensions of the air
inlets and outlets can be found here: Technical data, Air inlets and outlets,
The air outlet is always installed in the lower part of the wall, diagonal to the sauna
heater.The air inlets and outlets 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 xed to a suitable location on the cabin’s external wall, and the
corresponding temperature sensor according to the installation instructions that
accompany the control units inside the sauna cabin.

36
EN General safety instructions
The 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. Ensure that the heater is installed in compliance
with the standards and legal norms valid in your country.
The cabin door must open outward and must not have a lock that cannot be opened
in the case of failure. We recommend magnetic or spring locks.
All electrical installations and equipment in a sauna must comply with the IEC
60364-7-703 (DINVDE 0100-703) norm.
1.2 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 re arises in the event of improper repair work.
This risk remains also after work is completed.
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 heater or protective guards can easily be ignited and cause
res.
Attach the heater guard rail.
Do not place objects on the heater.
Fill the stone grate as directed.
Inspect the sauna cabin prior to each commissioning.
If you switch on the heater using pre-set timers or a remote control, attach a protec-

37
General safety instructions
tive cover to the heater or install a suitable safety system.
►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.
►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.
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.
►Operation by children or persons with reduced mental capacity
This unit should not be used by children or persons with reduced mental capacity or limited

38
EN General safety instructions
physical or sensory abilities. Children must not play with the unit.
Children or persons with reduced mental capacity, or limited physical or sensory
abilities must be supervised to ensure they do not play with the unit.
Children under 8 years of age should not operate the sauna cabin.
The settings for the heating time must only be changed by children under 8 years of
age if they are supervised by an adult.
The sauna cabin must only be used by persons with reduced mental capacity, or
limited physical or sensory abilities under supervision or if they have been previous-
ly instructed in its use and understand the risks.
Children and persons who have not received proper instruction must not clean or
service the system.
