1. Release the iron from its lock system (11) by pulling the lever
located at the heel of the iron backwards
2. Remove any label or protective covering from the soleplate.
3. Place the appliance horizontally on a solid, stable surface. You
may remove the iron pad from the appliance and place the iron on
it on another solid, stable, horizontal surface.
4. Fill the water tank (1), making sure not to pass the level mark.
5. Unwind the mains cable (9) fully and plug it into an earthed
socket.
6. Set the main power switch (7) to the on position (illuminated in
red).
7. The “Steam ready” indicator lamp (4) will light up after several
minutes, indicating that the appliance is ready to use.
The steam generator will take more time to reach “Steam ready” state
only upon the initial heating up, or after performing the de-scaling
operation (Calc’n’Clean).
When water is already present in the steam generator during regular
use, heat up time to reach the operating temperature will be faster.
8. This appliance has a built-in water level sensor. The “refill water
tank” indicator (6) will light when the water tank is empty.
- The iron is no
t designed to rest on its heal.
Please always position it horizontally on the iron
pad (2).
- The iron pad can be placed into the specially
designed recess on the appliance or somewhere
suitable alongside the ironing area.
Never rest
the iron on the appliance without the iron pad!.
- During it first use the iron may produce certain
vapors and odors, along with white particles on
the soleplate, this is normal and it will stop after a
few minutes
- While the steam
release button is pressed, the
water tank may produce a pumping sound, this is
normal, indicating that water is being pumped to
the steam tank.

3.3 Measuring of the hardness of the water
In order to determine the hardness of the water used for ironing, there
are strips available (ref 056317) that are used as follows:
1. Briefly wet the strip.
2. Shake once.
3. Determine hardness after 1 min:
3.4 Setting the temperature
1. Check the ironing instruction label on the garment to determine
the correct ironing temperature.
2. Turn the temperature selector (14) to the required setting:
3. The indicator lamp (17) will remain lit while the iron is heating
and go out as soon as the iron has reached the selected
temperature.
Tips:
- Sort your garments out based on their cleaning symbol labels,
always starting with clothes that have to be ironed at the lowest
temperatures.
- If you are not sure what the garment is made of then begin
ironing at a low temperature and decide on the correct
temperature by ironing a small section not usually seen when
worn.

214_58300000171747_ARA_EN_A – 01.03.a Seite 7 von 39
3.5 Ironing with steam
The steam control is used to adjust the amount of steam pro-
duced when ironing.
1. Turn the temperature selector to the required setting.
2. Set the amount of steam to suit your needs, using the variable
steam control (depending on the model).
For normal use, please choose one of the following recommended
settings:
3. Press the steam release button to release steam.
When ironing on a lower temperature setting “•”.
►If the appliance has variable steam control, set the variable
steam control to its lowest position (“ ”).
►If the appliance does not have variable steam control, press
the steam release button only for a few seconds at a time
when ironing at lower temperatures.
In both cases, if you find that water is dripping out of the soleplate, set
the temperature selector to a higher position (take care that the
garment can be ironed on this heat temperature setting).
3.6 Ironing without steam
1. Set the required ironing temperature.
2. Begin ironing but without pressing the steam release button (12).
3.7 Vertical steam
1. Set the temperature control to the “•••” or “max” position.
2. You can steam iron curtains and hanging garments (jackets,
suits, coats...) by placing the iron in a vertical position and
pressing the steam release button.
Important!
The monotube can be heated if ironed for long periods;
This is normal.

214_58300000171747_ARA_EN_A – 01.03.a Seite 8 von 39
Attention!
Never direct the steam jet at garments that are being
worn.
Never aim the steam at people or animals.
3.8 Cleaning & Maintenance
1. After ironing, pull out the plug and allow the appliance to cool down
before cleaning.
2. Wipe the housing, handle and iron body with a damp cotton cloth.
3. If the soleplate is soiled with dirt or scale, clean it with a damp
cotton cloth.
4. If the cloth is synthetic, it may melt due to the high temperature on
the soleplate . Switch off the steam and rub off any residue
immediately with a thickly folded, dry cotton cloth.
5. Never use abrasive products or solvents.
To keep the soleplate smooth, you should avoid hard contact with
metal objects. Never use a scouring pad, or chemicals to clean the
soleplate.
Important!
Always unplug the appliance from the mains supply
before carrying out any cleaning or maintenance
operation on it.
3.8.1 Cleaning the Boiler (calc’n clean)
To extend the life of your steam generator and to avoid any build up of
scale, it is essential that you rinse out the boiler after several hours of
use (approximately after 50 hours). If the water is hard, increase the
frequency.
Do not use descaling agents for rinsing out the boiler, as they could
damage it.
Depend on the model, pilot light (6) will flash indicating that boiler
must be rinsed.
1. Check that the appliance is cold and unplugged for more than
2 hours, and that the water tank (1) is empty.
2. Place your appliance on the edge of your kitchen sink.
3. Remove the plastic cover located on the bottom of the
appliance by turning it to the position.
4. Unscrew the boiler drainage plug using a coin.

214_58300000171747_ARA_EN_A – 01.03.a Seite 9 von 39
5. Holding your steam generator in upside down position, and
using a jug, fill the boiler (in the base unit) with 1/4 liter of
water.
6. Shake the base unit for a few moments and then empty it
completely over a sink or bucket. To obtain the best result, we
recommend that this operation is done twice.
Important!:
Before re-closing, make sure no water remains in the
boiler.
7. Replace and tighten up the boiler drainage plug with a coin.
8. Insert and close the plastic cover by turning it to the
position.
To reset the “Calc'n'Clean” counter, switch the steam station off
twice, keeping it off for at least 30 seconds each time.
(on → 30s off → on → 30s off → on)
3.8.2 Rinsing the iron steam chamber
Caution!
Risk of burns!
This procedure helps to remove scale particles out of the steam
chamber. This cleaning procedure may be performed occasionally
(approximately once a year), when after a long period of use with very
hard water, scale particles start to come out of the soleplate.
a) Ensure that the iron is cooled down.
b) Set the temperature selector (12) of the iron to the “min” position.
c) Fill the tank with tap water.
d) Plug in the mains cable and set the main power switch (7) to the “I”
position.
e) Wait until the “steam ready” indicator lamp (4) lights up.
f) If the steam station has steam regulator (5*), set it to the maximum
position.
g) Hold the iron over the sink or a container to collect the water.
h) Press the steam release button (13) and gently shake the iron.
Boiling water and steam will come out, carrying scale and or deposits
that might be there. This could take approximately 5 minutes.
i) Set the temperature selector (12) of the iron to the “max” position,
without pressing the steam release button (13-14*). The water in the
steam chamber will start evaporating. Wait until all the water inside the
chamber has been evaporated.
j) To clean the soleplate, immediately rub off any residue by running
the hot iron over dry cotton cloth.

3.9 Storing the appliance
1. Always allow the appliance to cool down before storing it.
2. Set the main power button to the “0” position (the red light will
go off) and disconnect the mains cable.
3. Empty the water tank.
4. Place the iron on the iron pad (2), standing on the soleplate,
and fix it by inserting the tip of the iron into the front slot and
moving the secureLock lever against the heel of the iron.
5. Store the mains cable and steam hose in the storage
compartment. Do not wrap the cords too tight.
6. Use the iron´s handle when moving the appliance, or use the
carrying handles (3) on either side.
3.10 Kind of water to be used
Normal tap water can be used. To prolong the optimum steam
function, mix tap water with distilled water 1:1. If the tap water in your
district is very hard, mix tap water with distilled water 1:2.
You can inquire about the water hardness with your local water
supplier.
The water tank can be filled at any time while using
Attention!
To avoid damage and/or contamination of the water
tank and the boile
r, do not put perfume, vinegar,
starch, descaling agents, additives or any other type
of chemical product into the water tank.

4 COMPONENTS
4.1 Steam station components
4.1.1 General overview

214_58300000171747_ARA_EN_A – 01.03.a Seite 12 von 39
4.1.2 Control panel area
1. LED “Refill water tank”: LED that lights when the water tank
float is below a certain level.
2. LED “Steam ready” / “secure”: LED that illuminates when
inside the boiler has reached the proper pressure (when the
boiler NTC detects temperature above 150ºC)
3. Main switch: The steam station power ON/OFF switch.
4. ECO function switch: Enables or disables the ECO function
which reduces the temperature inside the boiler and thereby
the overall consumption of the appliance
5. Steam regulator knob: Knob connected to a potentiometer,
which through the signal that sends to the electronics, controls
the amount of steam that is sent to the iron.
4.1.3 Water tank area

214_58300000171747_ARA_EN_A – 01.03.a Seite 13 von 39
6. Water outlet: This hose takes water from the tank to the
pump, which then drives it towards the boiler.
7. Ventilation inlet for priming the pump: To avoid the pump
to work in vacuum, at the outlet of the pump there is a safety
overpressure valve. This valve opens when there is a
blockage or overpressure at the entrance of the boiler, and
directs the water back into the tank.
8. Float: It contains a magnet, to lower the water level, is
approaching a switch Reed (lack of water sensor), which
activates the LED of lack of water.
9. Without water sensor: Reed switch that closes when float
reaches the bottom of the tank. When the Reed switch closes,
lights the indication of lack of lack of water.
4.1.4 Pump
10. Pump: The pump drives water from the tank into the boiler. It
is activated in two situations:
►When the upper boiler NTC (18) detects more than 190ºC
(empty water tank).
►When the lower boiler NTC (16) detects more than 170ºC.
Important!
The pump has a diode, so it is important to respect
the polarity of the connections

12. Boiler: Is the element responsible for heating the water that
comes from the tank to reach the adequate pressure steam.
This includes the following components:
►Heating element: Located in the interior of the boiler.
Resistance connections are (13) y (14).
►2 NTCs: In the external sides of the boiler there are two
temperature sensors NTC type, that controls the filling
(activation time and stopping of the pump):
Lower NTC (16): controls the boiler filling during normal
operation
Top NTC (18): controls the initial filling and acts as
security against overheating.
NTC - check: nominal value 100k
Ω
at 25ºC
►Thermofuses (17): As security elements, the boiler has two
serially connected thermofuses that cut power to the
resistance in case of overheating.
►Water inlet (19): Hose that connects the pump with the boiler.
4.1.6 Solenoid valve
20. Solenoid valve: At the exit of the boiler there is (normally
closed) a solenoid valve, allowing you to dispense steam
according to the following levels:
Handle switches of the iron without pressing: solenoid valve
closed, and the flow of steam leaving the boiler is null.
Handle bottom switch of the iron whit pressing: solenoid
valve open, opening the way of normal steam flow towards
the iron.
Handle top switch of the iron whit pressing briefly: the PCB
sends open the solenoid valve 3 times short and followed

214_58300000171747_ARA_EN_A – 01.03.a Seite 15 von 39
by: openings are very short, so the steam pressure can be
maintained to maximum, and the steam flow is higher
(“ultimate steam”).
21. Steam outlet to the iron: through the valve of the steam flow
control.
22. Air inlet into the water tank: during the expulsion of steam,
the deposit must be in contact with the air, to avoid the
creation of vacuum in the boiler. To do this, the solenoid valve
includes an air inlet from the outside.

214_58300000171747_ARA_EN_A – 01.03.a Seite 16 von 39
4.2 Iron components
1. Thermostat + thermofuse: The thermostat is the element
responsible for regulating the temperature of the soleplate
depending on the selection made by the user on the iron
temperature regulator. If the temperature of cutting at maximum
power (position "ooo" of the regulator) is 170 - 240°C in the
center of the soleplate is properly regulated. It is not factory
set.
In the same set, is included a safety bimetal, that acts as
thermofuse (temperature limiter) and interrupts the power supply
when the safety in the event of thermostat failure, temperature is
exceeded.
2. Steam intake: connection of steam hose from steam station.
3. Electricity supply: Phase and neutral
4. Electricity supply: Earth

5 FUNCTIONS
5.1 Flowchart
The pump draws the water from the tank to the boiler. Priming the
pump valve returns water to the tank if the pressure is of-overreach
high.
The water is heated in the boiler until it is in steam phase and up to
the T connection.
If the boiler pressure is very high, the steam escaping through the
pressure to the tank valve.
Pressing the steam button, activates the solenoid valve, steam comes
out of the tank and goes to the steam regulator. The tank steam
induces a negative pressure in the boiler, which is balanced by the
entry of ventilation.
The amount of steam coming out of the iron can be adjusted by the
steam regulator knob (depend on the model).

5.2 Regulation
5.2.1 Connection
The resistance power and the tank filling, are controlled by two NTC
and a pressure switch (model dependent), whose data are evaluated
by the PCB.
After switching on the unit, first checks if there is enough water in the
boiler. To do this, feeds the resistance. If the tank is empty, the
temperature of the air inside rises quickly. When NTC1 temperature
reaches 190ºC, the resistance power is cut off and the pump starts for
6 seconds to ensure that the resistance is below the water level.
5.2.2 Filling
The pump always works at intervals of 6 seconds and turns until
NTC1 temperature drops below 170ºC. During the initial filling, the
resistance is active, except for 6 seconds, during which still no enough
water in the boiler. When the water level reaches NTC1, sensor
temperature quickly drops below 170ºC and electronics interprets this
as "full tank" signal and stops the pump.

5.2.3 Steam generation
The power of resistance and therefore the generation of steam are
controlled by the NTC2 and the pressure switch (model dependent).
The NTC2 feeds the resistance when the measured temperature is
145ºC or below; when the temperature is higher than 145ºC the
resistance power is cut off.
The indication of "steam ready" is also controlled by the NTC2 sensor
and lights up when it reaches 120ºC.
The pressure switch has a security feature, so it cuts the power of
resistance when 4 bar are reached.
5.2.4 Refilling
When the "steam ready" display lights up, the user can extract steam.
To do this, press the switch in the iron handle, and the solenoid valve
opens to expel steam at high pressure. If the NTC2 temperature drops
below 145ºC, start the heating of the resistance, until NTC2
temperature is 145ºC or the pressure switch measures 4 bar. In this
way, the water from the inside of the boiler becomes steam, causing it
to lower the water level. If the water level falls below the NTC1 sensor,
the temperature increases rapidly. When the temperature reaches
180-190ºC, restarts the pump to fill the boiler with water.

5.3 Auto shut-off (model dependent)
If during ironing, the steam release button on the iron handle is not
pressed for a certain length of time (8 minutes), the steam station will
automatically switch off.
In this case, the “auto shut-off” pilot lamp will flash:
To switch the steam station back on, press the steam release button
again.
Technically, this is done, including the Timer function in electronics,
which makes that after 8 min., disconnects the boiler and the
soleplate.
5.4 Energy saving (model dependent)
If the “Energy saving” button (8*) is switched on, you can save up to
25% of the energy and 40% of the water consumption (in comparison
to the maximum setting), and still achieve good results when ironing
most of your garments. It is advisable to use the normal energy setting
only for thick and very wrinkled fabrics.
Technically, the ECO function is to lower the temperature a few
degrees and therefore the pressure within the boiler. When the ECO
key is pressed, electronics cut before the boiler heating, but always
maintaining the temperature at levels sufficiently high to generate
steam.
The effect of this reduction in temperature is lower overall
consumption of the appliance:
•Set max. steam: aprox. 1,54 KWh
•Set max. steam + energy saving: 1,01 kWh
•Set min. steam + energy saving: 0,76 kWh
