!WARNING
Risk of burns through hot surfaces in the device.
The steam generator has hot surfaces, e.g. pipelines, water tank,
which may cause burns.
• Keep a secure distance to hot surfaces of the device.
!ATTENTION
So-called plasticizers are able to modify the water surface tension in the
steam generator water tank.This can lead to strong foaming, so that the
hot water may come out of the steam outlet. Furthermore this can lead
to incorrect water level detection and overheating errors.
Please ensure that the water supply is clear of plasticizers or similar sub-
stances.
Plasticizers and similar substance are, among others, oils (e.g. essenc-
es), detergents, lubricants or specic chemicals contained in plastics like
PVC. It must be ensures that the water supply line does not use any ma-
terials which may contain plasticizers.
!ATTENTION
In areas with hard water (over 5° dH), it is recommended to install a water
softener to remove lime or a system for automatic descaling.
The softener must not be foam-forming or contain harmful chemicals. This is
especially advisable in public areas.
!ATTENTION
This device can be used by children over the age of 8 or by persons with

• Connect the cold water supply using the included water connection hose to the water
supply connector (3/4”) on the bottom side of the generator. The supplied water should
have drinking water quality. The water pressure in the supply line should be 2 to 8 bar.
• Connect the main drain and the additional drain hose from overpressure release valve at
the bottom of the generator to the drain system. Please notice that the generator has an
automatic drain system.
• Caution: the drain water may be hot, the appropriate precautions should be met.
• The limescale contained in water will lead to deposits on the inner surfaces of the water
tank, which may cause overheating and considerably reduce the service life of the heat-
ing elements and of the generator.
• By commercial use it is obligatory to install a water softening system in order to reduce
the amount of limescale getting into the generator with water. By home use such wa-
ter softening system is recommended by water hardness from 14° dH (~ 2,5 mmol/l).
Make sure to observe additional notes on the pages 35-37!
Notice: damages resulting from the limescale deposits are excluded from warranty!
Important Notice:
Please observe the EN 1717 / DIN 1988 and DIN 1986 / EN 12056 4 requirements. It must be ensured
that the water may not ow back into the water supply system. If necessary the additional equipment
has to be installed to prevent the back-ow. Please consult your water supplier or specialist dealer.
5.7 Water supply and drain connection
Important! The diame-
ter may not be smaller!
Important! No sharp
bends in the drain pipe!
How to connect the drain:

19
EN
5.8 Steam pipe connection
• The steam pipe should be heat-resistant to at least 110°C. We recommend copper or
stainless steel pipes with Ø35 mm. Do not use small diameter steam pipes!
• The steam pipeline should be reclining towards the steam outlet. Sharp angles should
be avoided. If there is a risk that the water condensate may block the pipeline a syphon
has to be integrated. The layout of the pipeline should prevent the back ow of the con-
densed water into the generator.
• Use the supplied 2-part brass union 1 ¼“ to 35 mm for steam pipe
connection. This will facilitate the connection or disconnection
of the pipeline.
• The steam output pipe features an innovative pivot
joint connection at the water tank lid.You can turn the
pipe around to rise upwards. For this unscrew the x-
ation nut in the bottom plate and turn the steam pipe
around. Push out the knock-out circle in the housing
before mounting it back on the chassis.
Notice: by the use of essence dosing systems the essence
injection line should be connected to the steam pipe so that no essences may get into the
water tank with the back ow of the steam or water condensate. Even the small quantity
of essences in the water tank may lead to malfunctions. Place the injection point possible
close to the steam outlet.
Pic. 4
Pic. 5
Connect and lead the steam pipe correctly!
• No sharp bends.
• Should decline towards steam outlet.
• Diameter may not be smaller.
• Avoid water condensation in the pipe.

20 EN
6. Electrical connections
Danger! Risk of electric shock. In the event of a faulty electrical installation,
there is a risk of electric shock (even after completion of the installation work).
The electrical installation may only be carried out by a qualied electrician.
The connections are made according to the connection diagram or according to the following
terminal diagrams - see Fig. 6 or Fig. 7.
Make the electrical connections as shown on the connection diagrams on pages 18 - 19.
The generator has a pre-mounted power supply cable with a Cekon type plug (16A or 32A). For
connection the appropriate socket with fuse protection has to be used.
The control unit is connected as shown in the connection diagram on pages 21-22.
In order to simplify the installation, the terminals are color-coded and numbered individually.
