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
(waterlter)mustbeinstalledinfrontofthe
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
CaCO3(USA) 1 ppm = 0 0 0 1 0

1.2 Installation locations and con-
nections
• Theassemblylocationofthesteamgen-
eratormayliemax.oneooraboveorbe-
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.
• Forthewaterdrainforcontrolandclean-
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
arebrieyabletohold5-7lofuid.
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
withsufcientheatinsulation(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
inuences(kinkingordeformation).
Only45°bendsmaybeusedduetoow
reasons.
• Connecttheoptionalsupplyairfanwiththe
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.

construction kit included in delivery is re-
quired. Carry out installation of the skeleton
construction according to the Installation
overview.

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.
