1.2 Technical safety notes for assembly and installation
DANGER!
The control device can be installed directly on the outer side of the
cabin or at another location, however not within the cabin
Note!
Appropriate VDE applies to public steam baths, that a control
lamp, showing, that the evaporator is switched on, is to install in
the room of the supervisor.
This lamp can be connected to the clamp (FLE-STB).
For switching off the mains, the power supply cable must be
equipped with a fuse with a contact opening width corresponding
to the requirements of the excess voltage category III for total
disconnection.
At FCUxxxx-Steam-Design-Glas the main switch of the control unit
must be accessible.
The sensor of the thermostat must be installed in such a way that
it is not affected by the incoming cool air.
1.3 Intended use
Depending on the version, the FASEL steam bath controls of the series FCU2000,
FCU3000 and FCU4000 are exclusively meant for operation and control of steam bath
cabins. The control devices are permitted for domestic and commercial application.
Intended use
WARNING!
Danger if not used correctly
Any improper use of the steam bath control can lead to dangerous
situations.
Therefore:
– Use the steam bath control as instructed.
– Operate the steam bath control only within the permissible room
temperature and moisture range. →See page 9.
– All the specifications in the operating manual and the installation
manual must be strictly adhered to.
Claims of any type due to damages caused by improper use will not be accepted. Only
the user is responsible for damages caused by improper use.
1.4 Modifications and alterations
Modifications and alterations of the steam bath control or installation can lead to
unforeseen dangers.
All technical modifications and add-ons to the steam bath control require the written
permission of the manufacturer.

1.5 Demands on technical personnel
The assembly, installation, commissioning as well as rectification of defects and repairs
must be carried out by qualified persons only unless otherwise mentioned.
Inadequate
Qualification
WARNING!
Danger of injury due to inadequate qualification
Improper handling can lead to significant personal injuries and material
damage.
Therefore:
– The assembly, installation, commissioning as well as rectification of
defects, maintenance and repairs must be carried out by qualified
persons only unless otherwise mentioned.
Technical personnel
Due to their technical training, knowledge and experience as well as the knowledge
of the relevant regulations these persons are in a position to carry out the tasks
assigned to them and to identify possible dangers on their own. Also they are
familiar in handling with ESD sensitive devices.
Certified electricians
Due to their technical training, knowledge and experience as well as the knowledge
of the relevant standard specifications and regulations these experts are in a position
to carry out jobs on the electrical unit and to identify possible dangers on their own.
In Germany certified electricians have to fulfill the stipulations of the accident
prevention regulation BGV A3 (e.g. master electrician). In other countries
corresponding stipulations are applicable that have to be followed.

1.6 Operational safety and special dangers
Pay attention to the safety and warning notes in the following chapters of this manual to
minimize health hazards and to avoid dangerous situations.
The following instructions are to be adhered to for your own safety and the safety
of the unit:
Electric
potential
DANGER!
Danger to life due to electric potential!
Contact with live components can be fatal.
Damage of the insulation of the individual components can be
dangerous to life.
Therefore:
– For switching off the mains, the power supply cable must be
equipped with a fuse with a contact opening width corresponding to
the requirements of the excess voltage category III for total
disconnection.
– Disconnect the unit from the mains before carrying out any work on
it (switch off the fuse in the distribution box) and secure against
restarting. Check for zero potential. The control device should be
disconnected from the mains before opening the casing.
– In case of damage to the insulation, switch off the power supply
immediately and carry out the repair.
– Work on electrical unit should be carried out by certified electricians
only.
– Never bypass fuses or put them out of operation.
– While replacing fuses, pay attention to correct current specifications.
– Keep moisture away from live components, since it can lead to
short circuit.
WARNING!
If a short circuit occurs in a 230V/400V load, the relay contact can
be welded by the high short-circuit current. Is turned on before
removing the short circuit, the safety relay can be also welded.
This can lead to the continuous operation of the load. Turn off the
circuit breaker in the junction box. Send the unit back to the
factory for check/repair.

2.3 Cables
Use of
inappropriate
cables –
Electric
potential
DANGER!
Danger to life due to electric potential
Use of inappropriate cables can lead to short circuits and
subsequent fires.
Damage to the insulation can be dangerous to life.
Therefore:
– All the cables, which lead to the sauna, must be designed for at
least 150 °C.
– When laying the cables in the ground, it is essential to use a
cable approved for underground installation. Signal lines must
be routed in a separate trench, not in the same trench as the 230
/ 400V lines.
– Use cables as per specifications in Table 4 and electrical circuit
diagram (see annexure). The specified cross sections are
designed for copper cables. In case of aluminum cables the
cross sections should be appropriately increased.
– The cross sections can increase due to the length of the cables,
the type of cable laying or special regulations.

another length is desired then the cable must be configured by the
electrician. Another option would be to bridge a stretch by installing two
network sockets (CAT 5).
