1. General information 1.1 Device functions
Your steam generator is a high-quality,
electrically-operated unit. Operation takes
place via a panel with switching possibilities
for steam, fragrance, exhaust air and light,
which can be installed both inside the cabin
as well as on the unit. The temperature con-
trol also takes place via the panel.
The electrical / electronic components and
the steam tank made of stainless steel are
arranged in a housing.
The water feed is automatically controlled,
whereby a manual drain, for example for
cleaning the device, is possible.
The housing consists of deep-drawn plastic.
The steam tank and all wear parts are made
of stainless steel.
The steam generator works without pres-
sure.
The electrically operated resistance heaters,
which are made of stainless steel, are inte-
grated into the steam tank.
This principle works almost independently of
the water quality.
Permanent steam production is ensured
through the automatic water level control.
The optional supply air fan ensures opti-
mum steam distribution through the supply
of fresh air.
Important note
Contact your water supply company and
ask about the hardness level of your wa-
ter. Within the hardness range I (0-8.4°
German degree of hardness), the device
generally works without faults and is des-
caled through the descaling unit installed.
Should your water lie within the hardness
ranges II - III, a water treatment system
(waterlter)mustbeinstalledinfrontofthe
evaporator.
Conversion for water hardness units
°dH °e °f ppm mMol/l
German degrees 1°dH = 1 1 2 18 0
English degrees 1°e = 0 1 1 14 0
French degrees 1°f = 0 0 1 10 0

1.2 Installation locations and con-
nections
• Theassemblylocationofthesteamgen-
eratormayliemax.oneooraboveorbe-
low the steam cabin and the length of the
line between the steam generator and the
steam jet should not exceed 6 m.
If the distance is larger, the steam line
must be selected one dimension larger
than stated in these instructions.
Two steam jets should be provided for
steam generators >9 kW.
Please follow the instructions below for
assembly of the system components.
• The electrical installation must be de-
signed acc. DIN VDE 0100.
The system must be supplied via a separate
power circuit with a residual current circuit
breaker (I Δ= 30 mA) which disconnects
the device at all poles from the mains with
a contact opening width of at least 3mm.
The electrical installation may only be un-
dertaken by a licensed electrician.
• The steam generator water connec-
tion is a 50 cm-long reinforced hose (R
3/8") on a connection bracket provided
on-site (R 1/2") with 1-6 bar water pres-
sure, directly from the water mains.
At more than 6 bar water pressure, a pres-
sure reducing valve (setting 4-6 bar) is to
be provided.
• Forthewaterdrainforcontrolandclean-
ing purposes, the drain must be con-
nected with the outlet via a funnel si-
phon made of heat-resistant material.
The funnel and the drain must be di-
mensioned large enough so that they
arebrieyabletohold5-7lofuid.
Place the collecting funnel at least 30 cm
below the drainage outlet.
• Provide the following connection lines /
empty pipes
Designation Empty pipe Line
Temperature sensor Yes 2 x 0.5 mm²
Wall lamp Yes 2 x 1.5 mm²
Fragrance dosage pump
Yes 4 x 0.75 mm²
Supply air fan Yes 3 x 1.5 mm²
• For the steam line, the minimum
pipe diameter must be 35 mm.
The steam line(s) from the steam gen-
erator to the steam jets should be
made of copper or stainless steel pipe
withsufcientheatinsulation(20mm).
You can nd the position of the
steam jet in the cabin drawing.
The steam line must not be lockable
and it must not be possible to shut it
off. It must be protected against outside
inuences(kinkingordeformation).
Only45°bendsmaybeusedduetoow
reasons.
• Connecttheoptionalsupplyairfanwiththe
steam jet using a pipeline (HT pipe DN 40).
For assembly, please observe the Assem-
bly instructions enclosed with the fan.
Always mount the applica-
ble check valve horizontally.
If possible, do not mount the supply air fan
on the outer wall of the cabin.

Important notes:
The regulations of EN 1717 or DIN 1988
part 4 must be observed. Suitable measures
must be taken to avoid water owing back
into the drinking water mains. Pipe dividers
or system dividers are suitable for this. Ask
your drinking water supplier or a specialist
sanitary dealer.

2.6. Steam line
The steam line must always be designed
in copper or stainless steel (min. Ø 22 mm,
we recommend 35 mm to prevent noises
developing) for all steam generators, here
narrow 90° bends in 2 x 45° are to be laid.
The steam line insulation should be de-
signedwithIsover,ArmaexHTormateri-
als of the same quality to a thickness of 25
to 30 mm.
When laying the steam line, please ensure
a gradient ( min. 1cm / m ) in the direction
of the steam jet in order to avoid conden-
sation build-up (water trap). The steam
line should not exceed a length of 5 m.
Pressure build-up in the steam line is not
permissible.
As additional equipment for the automatic
fragrance dosage, a ½" sleeve must be
positioned just before the steam jet in the
steam line gradient. It must be ensured
that the fragrances cannot ow via the
steam line into the steam generator.

Should several steam jets be mounted in
the cabin as shown in the adjacent diagram
, the connections of the supply air and steam
lines should be placed as close as possible
to the respective steam jet.

2.8. Installation of the fragrance system
The optional fragrance dosage valve must be installed in the falling steam line. It must be

ried out via a poppet valve which is included in the additional accessories for the exhaust
air fan. The poppet valve must be connected on-site to an exhaust air pipe which should
lead directly out into the open air. We do not recommend the connection of central ventila-
tion systems due to the risk of possible condensation formation.
For installation of an exhaust air fan (additional equipment) into the exhaust air line, an
empty pipe connection must be provided to the steam generator according to the Installa-
tion overview.
2.9.1. Supply fan
(Additional equipment - recommended from
SteamTec Premium 6.0 kW)
The connection of the supply air (Ø 35 mm in
Cu) with the steam line should be carried out
on-site as close as possible to the steam jet.
Should several steam jets be mounted in
the cabin as shown in the adjacent diagram
, the connections of the supply air and steam
lines should be placed as close as possible
to the respective steam jet.

3. Electrical installation
During the electrical installation, the re-
spective VDE, country and EVU regu-
lations must be maintained in their re-
spective valid version. Installation and
inspection work is to be carried out exclu-
sively by a licensed electrician, taking the
valid standards into account.
The power supply must be provided tak-
ing the required line cross-section into ac-
count. The electrical installation must be
designed acc. DIN VDE 0100. The system
must be supplied via a separate electrical
circuit feed line. Furthermore, the steam
generator must be protected by a sepa-
rate residual current circuit breaker (I∆
= 30 mA), which disconnects the device
on all poles from the mains with a contact
opening width of at least 3 mm. The elec-
trical installation may only be undertaken
by a licensed electrician.
All electrical lines connected to the steam generator are to be laid according to the drilling
template on the steam generator in the area of the connection. An approx. 0.5 m cable length
is required for connection to the device. The maximum line length to the operating panel is
7 m!
