1.5 Intended use
The SteamRock II Basic steam generator is intended for production of steam in steam rooms or
sauna rooms with humid operation. The SteamRock II Basic requires an external control unit (e.g.
EOS Econ S2) which is not included in the scope of delivery. Third party control units may not be
used without prior written consent of EOS Saunatechnik GmbH.
1.4 Foreseeable incorrect use
Following may be regarded as foreseeable incorrect use:
• Steam room size does not match the steam generator power (incorrect power selection).
• Incorrect connection of the steam generator and control unit.
• Operation without proper knowledge of the safety instructions (chapter 3).
• Operation without adherence to the required operation rules, maintenance and servicing re-
quirements.
• Operation of the device after unauthorized technical alterations or repairs.
• The unit is operated by children or persons with reduced mental capacity or by persons who
have not been thoroughly instructed in its use.
• Operation or use by persons with certain ailments or health conditions, such as for instance
heart and cardiovascular disorders, which might lead to physical injuries through the use of a
sauna or a steam room (a doctor should be consulted in advance).

General safety instruction - Mounting and electric installation
These installation instructions are intended for qualied personnel familiar with
the laws and regulations applicable to electrical installations at the installation
site. Observe the following general safety instructions during assembly, setup
and commissioning.
DANGER
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 electri-
cal connection. This risk also applies following completion of the installation work.
• The electrical installation of the steam generator and other electrical systems or
equipment with a xed mains connection must only be performed by a trained
electrician from an authorised electrical company.
• Observe the stipulations in VDE 0100 part 701 or applicable local regulations.
• The system must be disconnected and removed entirely from the mains supply
before commencing installation and repair work.
WARNING
Fire hazard from overheating
Insucient ventilation can lead to device overheating and re.
• Do not install the control panel and power units in enclosed cabinets or wood
panelling.
• Do not install steam generators in enclosed cabinets or wood panelling.
WARNING
Risk of burns
Touching hot pipelines can result in skin burns.
• Insulate hot device parts.
• Insulate hot pipelines; they must not remain exposed.

EN
General safety instruction - Mounting and electric installation
WARNING
Risk of poisoning from steam
Descaler can react with other chemicals, which can create poisonous steam.
• Place the container for descaler only under the steam generatorand secure it so it
does not tip.
• Ensure that the container with descaler cannot be mistaken for the container with
essence.
• When relling 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.
WARNING
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.
• The hose for excess pressure and the drain outlet for emptying the vaporiser 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.
• Wear safety goggles/protective clothing (gloves).
WARNING
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 relling descaler.
• Clean contaminated clothing thoroughly.

EN
NOTICE
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 commercially.
NOTICE
Damage to the unit
Corrosive or heavy saline atmospheres damage the contacts in the control panel, in the
relay box and in the sensors.
• The control panel and sensors should not be installed in a corrosive or heavy saline
atmosphere.

EN
General safety instruction - Operator Instruction
The operator of the steam generator must be instructed in the general safety instructions dur-
ing commissioning. The operator must be given a copy of the instructions for use.
DANGER
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 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.
WARNING
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 steam supply and understand
how it is controlled.
WARNING
Health risks
Spending time in a steam room can lead to serious health risks or even death for persons
with health impairments.
• These persons must consult with a doctor before visiting a steam room.

EN
General safety instruction - Operator Instruction
NOTICE
Equipment damage due to overuse
In commercial steam rooms, excessive humidity in the spatial surroundings of the steam
room(s) can lead to material damage
• In a commercial steam room, the steam generator must be set so that it turns itself
o after a specic period of time.
• If the steam generator does not shut itself o, usage must be supervised at all times.
• Inspect the steam room each time you start the system.
WARNING
Operation by children or persons with reduced mental capacity
Children and persons with reduced mental capacity can be a risk.
• Children must be supervised to ensure they do not play with the unit.
• Children under 8 years of age should not operate the steam generator.
• The settings for the steam generator may only be used by children over 8 if they are
supervised by an adult.
• The steam generator must only be started by persons with reduced mental capacity,

5.3 Installation location requirements
The steam generator is only intended for installation outside of steam rooms and is connected to
the room via a steam pipe. The following climatic conditions must be met at the installation site:
Ambient temperature during operation 5°C to 40°C
Air humidity during operation 30% to 75% rel. air humidity
Storage temperature: 0°C to 60°C
Stable wall for installation as the total weight can equal approx. 45 kg.
Near the unit: Mains connection 400 V 3N AC, with standardised CEE plug sockets (not with sing-
le-phase connection)
Drain outlet below the unit or in close proximity
Water supply line in close proximity
Length of steam pipe, max. 10 m
All pipelines and connections must be accessible for service.
The room in which the steam generator is installed should be as near to the steam room as pos-
sible so that the pipeline distances are as short as possible.

NOTICE
Damage due to inadequate installation site
The steam generator may vibrate slightly when the water boils.
If the wall bearing capacity is insucient or the wall is of poor quality, the steam generator
cannot be securely installed and may fall o.
Before installation, check the quality and bearing capacity of the wall intended for instal-
lation. The wall must be able to support a total weight of max. 45 kg.
Before installation, check how the steam pipe is to be laid. Standard routing leads the
line out from the steam generator downwards.
Measurements for installation
The following distances must be observed:
Distance bet-
ween drill holes
Horizontal: 420 mm
Vertikal: 535 mm
On the side to the
left and right
Min. 250 mm
Top Min. 500 mm
Bottom Approx 1000 mm
The space underneath the unit may not be
occupied by other installations.
