1. Erecting the frame
Complete the building according to the
plans.
1.1.Fresh water and dirty water
The way in which the pipes for the fresh
water and the dirty water are posiitoned
should be done with the help of the dril-
ling template which is included with the
materials
1.2.Electrical wiring
The electrical wiring must take into full
consideration the requisite conductor
cross-section. The mains electricity must
be connected in accordance with DIN
VDE 0100. There must be a separate cir-
cuit for the system. The steam generator
must have a separate FI switch (IΔ = 30
mA) forsafety reasons so that the equip-
ment has a circuit breaker with a contact
opening of at least 3 mm from the mains
supply. The electricity should be connec-
ted to the mains only by a qualified elec-
trician.
X = This area is for the cable duct piping
to be used for the electricity supply lines
(control panel, temperature sensor, etc.)

1.2. Connection cables
It is advisable to use the drilling template so
that all the connections that are connected to
the steam generator can be drawn through
correctly. For the connection to the genera-
tor you will require a cable that is about 0,5
m long.
The steam generator is controlled by the
sauna control unit of your sauna system.
Use one of the following control units for this
purpose:
• EMOTEC HCS 9003
• EMOTEC HCS 9003 DB/DL
• or EMOTOUCH
always only in connection with the optional
humidity sensor.
A cable 5 x 1.5 mm² is required to connect
the control unit to the steam generator.
1.3. The steam pipe
For all types of steam generator the steam pipe must always be either of copper or high-
quality stainless steel (min. Ø 22 mm, we recommend Ø 35 mm in order to reduce the
noise level) and when it is being installed sharp bends must be at 90° in 2 x 45°bends.
The steam pipe insulation is best completed with either Isover, Armafl ex HT or similar
materials that are 25 - 30 mm thick.
When the steam pipe is being fitted care must be taken to ensure that it inclines towards
the steam outlet so as to prevent any blockage through condensation (water bag). The
steam pipe must be no longer than 5 metres. Pressure must not be allowed to build up
inside the steam pipe.
1.4. Aeration and ventilation
Care must be taken that the room where the steam cabin is set up is sufficiently aerated
and ventilated.
Connection to a central ventilation system is not recommended due to possible conden-
sation formation.

2. Final assembly
2.1.Dismantling the steam generator hood
• Below the steam generator there are two 32 x
16mm screws that must be unscrewed from the
hood.
Make sure that the hood is connected to the
steam generator through the cables to the display
panel. To remove the hood, loosen the plugs on
the connection cable.
• The assembly drill holes must be drilled in the
wall with the help of the template.
• Place the top screws in their dowels and tighten
them to 5mm from the wall.
• Hang up the steam generator and then tighten
the lower screws.
30 mm
• Screw on the flex-hose with the stainless steel woven casing already on the steam gene-
rator onto the mains water supply (3/8“).
• The water tank will be drained automatically during the flush programme
2.3. Steam connections
• Connect the steam pipe with the RG screw (1“ x 35) to the steam generator.
• You can fix the steam exit either on the right-hand side or below the steam generator.
• Connect the Steamfix of the sauna heater to the pre-installed 5/4“ x 35 sleeve.
Important Notes:
The regulations of EN 1717 and/or DIN 1988 Part 4 must be attended. Appropriate
measures must be taken that prevent the water from running back into the drinking water
pipeline. For this, especially pipe isolators or system isolators are appropriate. If necessary,
ask your drinking water supply company or your local sanitary expert.
2.2. Connecting to the water supply and drain
• Route all the electric cables from below through the PG screw connections or through the
rear wall.
Now connect the steam generator according to the following terminal diagram.
2.4. Connecting to the mains
When the mains are connected it is essential to comply with the local VDE EVU require-
ments as these currently apply. The mains must be connected and checked by a fully
qualified electrician to ensure that the applicable norms are adhered to in full.

2.5. Fitting the hood for the steam generator
Insert the connection cable to the display panel again and fit the hood in place.
Use the two screws to fix the steam generator hood under the the casing.
3. Service
• Please note that all the work must be undertaken only by fully qualified persons.
• Before any servicing is started the steam generator must be disconnected from the
mains.
• By further questions and technical queries please contact your local EOS dealer.
4. Operation
The Steamtec Classic is controlled by the sauna control unit belonging to the sauna heater.
More information can be found in the operating instructions for your sauna control unit.

3. Flushing and decalcification
The development of lime scale deposits due to hard water in the tank and on the radia-
tors reduces quite considerably the life of the heating rods.
We recommend that you use a chemical water softener with the steam generator (as an
extra) so as to prevent lime scale from developing.
The steam generator is equipped with a fully automatic self-cleaning system (flushing
and descaling), which may be programmed at site to match the local water quality.
The flushing or decalcification process starts automatically after a delay of 30 minutes af-
ter the steam generator has been switched off. The green LED „Decalcification / flushing“
lights up on the display panel.
Whenever the decalcification programme is run, the tube pump will fill up the steam tank
with approximately 100 ml of softening agent.
This will be allowed to work for about 30 minutes and then the water with the lime scale
in it will be drained out through the electr. ball valve.
The flushing valve flushes the container a second time, the ball valve will close and the
flushing programme will come to an end.
The running time for the flushing programme is about 35 minutes.
The steam generator cannot be switched on during this time.
Check regularly if there is still enough of the cleaner / descaling liquid in the container.
When the level in the container remains unchanged over a longer time this may indicate
a failure in the cleaning system. Check the steam generator immediately to prevent da-
mages from the scale building inside water tank.
If the softening agent supply has been almost used up, the red LED „Problem with softe-
ning agent supply“ lights up on the display panel.
The LED „operation“ lights up when the sauna equipment is in operation, independently of
whether the steam generator is working or not.
The steam generator is equipped with an overheating protection feature (Safety Temperatu-
re Limiter (STB in German)). If this STB reacts, the steam generator switches off and the red
LED „STB problem“ lights up on the display panel.
In this case, wait briefly until the steam generator has cooled down. Disconnect the sauna
control unit from the mains for about 5 seconds (switch off fuses or FI switch). The device
now works normally again. If the fault occurs again, have the device checked by your autho-
rised EOS partner.
