Cleaning and service work must be performed only by persons with the follo-
wing qualications:
Qualied personnel: Persons who have been instructed by the distributor
on how to perform service work.
Trained personnel: employees extensively trained by the distributor.
Authorised personnel: Persons with regulatory approval for a specic eld
of work, e.g. electrical installations.
These installation instructions are intended for authorised personnel
familiar with the laws and regulations applicable to electrical instal-
lations at the installation site. Observe the following general safety
instructions during assembly, setup and commissioning.
Risk to life and limb and risk of fire
Risk to life and limb from electric shock and re in the event of improper or faulty
electrical connection. This risk also applies following completion of the installa-
tion work.
The electrical installation of the steam generator and otherelectrical
systems or equipment with a xed mains connection must only be perfor-
med by a trained electrician from an authorised electrical company.
Ensure compliance with the applicable standards and regulations for elec-
trical installation.
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 trained specialist.
Fire hazard from overheating
Insucient ventilation can lead to device overheating and re.
Do not install the steam generator and control panel in enclosed cabinets
or wood panelling.
Observe the cabin manufacturer‘s safety and installation instructions.
1.2 Mounting and electrical installation

6EN
Touchable glass surfaces on the outside of the cabin must not exceed
76°C. Provide a protective system if needed.
Risk of burns
Touching hot pipelines can result in skin burns.
Insulate hot device parts.
Insulate hot pipelines; they must not remain exposed.
Risk of poisoning from fumes
Descaler can react with other chemicals, which can create poisonous fumes.
Place the container for descaler only under the steam generator and secu-
re it so it does not tip.
Ensure that the container with descaler cannot be mistaken for the cont-
ainer with essence.
When relling a container, ensure that descaler is not poured into the
container for essence.
Never place containers with descaler close to other chemicals.
Never place other chemicals close to the container of descaler.
Risk of scalding
Contact made with hot steam or hot water can result in scalding of the skin.
The steam pipe must always have an unobstructed exit outlet in the cabin
so that excess pressure does not build up in the vaporiser tank.
The hose for excess pressure and the drain outlet for emptying the vapori-
ser tank must be routed in such a way that there is no risk of scalding if hot
water escapes unintentionally.
When commissioning, take measurements to ensure that the set output
does not heat the cabin to over 50°C.

7
EN
Risk of chemical burns
Descaler consists of an acidic solution, which can burn eyes and skin.
Wear eye and skin protection when connecting the descaler line and rel-
ling descaler.
Clean contaminated clothing thoroughly.
Damage to the unit due to high levels of lime
Lime deposits clog the vaporiser tank, slowing down the transfer of heat to the
water. This can lead to malfunctions because of overheating and blockages in
the drain. A water softening system does not replace regular descaling.
Non-compliance with these guidelines resulting in damage to the unit renders
the warranty void.
Check the hardness of the water before installing the unit.
In locations where the water is high in calcium carbonate (above 5° dH), a
water softening system is recommended.
If the level on the hardness scale is 11° dH or above, connecting a water
softening system to the steam generator is recommended.
A water softening system is required if the steam generator is used com-
mercially.
Damage to the unit
Corrosive or heavy saline atmospheres damage the contacts in the control pa-
nel, in the relay box and in the sensors.
The control panel and sensors should not be installed in a corrosive or
heavy saline atmosphere.
Damage due to incorrect mounting location
The device 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 condensation or corrosive substances in the ambi-
ent air, as well as other weather conditions.
Similarly, excessive cold and extreme exposure to sunlight must be pre-
vented.
Protect the unit accordingly if there is an increased risk of mechanical
damage.

8EN
1.3 Operator instruction
The technician and/or distributor must instruct the operator of the steam gene-
rator in the general safety instructions when commissioning the unit. The opera-
ting instructions must be given to the operator.
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 also applies after work is completed.
The housing cover must only be removed by a trained 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.
Risk of burns and chemical burns
Touching hot parts may lead to skin burns and chemical burns of the skin.
The operator must be familiar with the unit‘s hot parts and be able to
identify them.
The operator must be familiar with the settings for the heat output and/or
steam supply and understand how it is controlled.
Health risks
Spending time in a steam room can lead to serious health risks or even death for
persons with health impairments.
Persons with health disorders must consult with a doctor before visiting a
steam room.
Equipment damage due to overuse
The uninterrupted operation time of the steam room can lead to property da-
mage.
In a commercial steam room, the steam generator must be set so that it
turns itself o after a specic period of time.
If the steam generator does not shut itself o, usage must be supervised
