3MACHINE POSITIONING
IMPORTANT
The machine must be positioned with its back against a wall (minimum distance 10 mm) and must be installed by an authorized
SMEG technician. The machine, when suitably prepared, can be placed under a work top
The technician who installs the machine is responsible for the appliance correct operation after it has been installed. The
technician must also provide all the necessary information to the user for correct use.
During installation, it is necessary to remove the scratchproof film on the outer steel surfaces.
The kit of installation accessories (seals and clamps) is located inside the wash chamber.
The machine can be placed up against the sides to the adjacent units, taking care to leave free venting of the steam on the
back: it is therefore advisable that the wall at the back is made of brickwork or some other impermeable material.
Furthermore ensure the heat does not reach any electrical circuits or sockets on the back of the appliance.
The machine is equipped with hoses to supply and drain off the water. These can be positioned towards the right or left,
depending on the installation requirements.
LEVELLING
After positioning the machine, adjust the feet by screwing or unscrewing them in order to adjust the height and level it using
a spirit level so that it is to be horizontal (max angle tolerance allowed: 0.5°).
Correct levelling will ensure that the machine operates in the right way.
CAUTION
Any adjustment, maintenance, etc.. must be performed with the device switched off and disconnected from power sources.
LIFTING AND TRANSPORT
The base of the machine, before leaving the factory, is fixed on a pallet which serves both for lifting and for the transport.
The machine must be handled with a fork-lift truck or transpallet.

Cw: WATER MAINS - essential:
For the operation of the machine it is required that the connection is to a water mains of "drinkable" quality having a hardness
of max. of 42°f (8°f for GW6290) and with the total content of dissolved iron, Fe2+ and Fe3+, not greater than 0.5 ppm.
Note: for all machines equipped with steam condenser it is advisable to use purified water, preferably with a maximum
hardness of 20 ° f.
Hw: HOT MAINS WATER - optional and available only on some models:
Connection to a water mains of "drinkable" quality having a hardness of max. 42°F (8°f for GW6290) and with the total content
of dissolved iron expressed as Fe2+ and (+) Fe3+ not greater than 0.5 ppm.
NOTE
In case the water supply contains iron Fe2+/Fe3+ in a quantity exceeding 0.5 ppm and / or the supply water has a hardness
greater than 42°f (French degrees) it is necessary to undertake a pretreatment of the water by installing upstream an iron
removal and/or softening system.
[Models GW6290 do not have an integrated softener: the maximum water hardness allowed is therefore 8°f.]

Dw: DEMINERALIZED WATER- optional (highly recommended):
If available, the demineralized water (conductivity < 30 µS) is recommended to have an optimal washing from the chemical
point of view, for a better elimination of the residues of the salts present in the water supply mains; the lack of this connection
does not affect the removal of dirt.
WARNING - NO DEMINERALIZED WATER
If demineralized water is not available on the system, do not connect the related hose to cold and/or
hot water inlet taps. Leave the "demineralized water" hose not connected.
It is necessary to adequately correct the machine SETTINGS - by the Authorized Service Center.
5.1.5 “PAD” ACCESSORY FOR DEMINERALIZED WATER NOT UNDER PRESSURE
The connection to a line of demineralized water not under pressure (e.g. gravity tank), is possible only by installing a special
booster pump.
Each model must be equipped with its own specific pump - see table below.
This pump ensures that the demineralized water enters with sufficient pressure for proper operation of the machine.
The PAD and PAD1 accessories are mounted externally and hooked on the back of the machine.
The PAD2 accessory is mounted outside the appliance. On certain models the PAD2 requires necessarily the use of
the kit “PAD2R”, see the Table below.

CAUTION
- FOR THE INSTALLATION OF "PAD" and "PAD1" MAKE SURE THAT:
The supply pressure of the PAD is less than 1 bar and greater than 0.1 bar.
- "PAD" and "PAD1" IN COMBINATION WITH TANK NOT UNDER PRESSURE
With reference to the following image, the tank must be at a distance L such that:
L > 100 cm
The value represents the distance between the support surface of the machine and the lower support
surface of the tank. This height ensures an inlet pressure to the PAD of approximately 0.1 bar.
- "PAD2" IN COMBINATION WITH A TANK NOT UNDER PRESSURE
With the installation of PAD2, the tank not under pressure can be at the same level of the support
surface of the appliance, with reference to figure L ≥ 0.

5.2 WATER DRAIN
Drain hoses of the machine: Rubber terminal with hose connector diameter 21mm (1/2").
The machine is equipped with one or more drain hoses, depending on the model.
The drain hoses are referred to as:
- d- machine drain hose –d(drain)
- cd - steam condenser drain hose (not always installed) –cd (condenser drain)
Dimension “I” –the distance of the drain from the appliance side, for all the models, must be: I < 50 cm
Dimension "H" –the height from the support surface of the machine: H_min < H < H_max
fig. 9–Schematic drawing. The hydraulic drain connections can be arranged on the right or left of the unit, always taking into account the maximum distance
indicated by the product “I”.

CAUTION
The dimension “Hin the figure must always be within the limits shown in the table: H_min and
H_max (for example for WD4060: H_min=65cm, H_max=80cm).
Dimension "X": The dimension "X" between the discharge connection and the highest part of the
tube should always be less than 20cm: X < 20cm.
Use only original Smeg parts.
CAUTION
The drain must comply with international regulations: our company accepts no liability for
pollution caused by improper use of the appliance.
DRAINAGE TRAP
The drainage trap in the system must preferably be composed of:
- a water tight seal (generally of a depth not less than 50 mm);
- a part which is easily removable for cleaning.
Requisite 5.25.1 EN ISO 15883-1
“The design of the drainage trap shall include the following:
a) a water seal (usually of a depth no less than 50 mm);
NOTE Local regulations applicable to the water seal can exist.
b) a trap which is removable for cleaning or is fitted with an accessible cleaning port.
NOTE This can be provided as part of the building installation.”
fig. 11 –Adapter with connector for 1/2" hose.
General guidelines for installing the drain
The use of an drain with syphon is recommended. During the installation procedure, the following precautions should be
observed:
Since the temperature of drain water is 95°C, the end of the drain hose must be installed permanently to the hose
connector, using the straps provided.
The drain hose must not have sharp bends leading to bottlenecks.
The end of the drain hose must be placed, with respect to the support surface of the machine, at a height conforming to
the specifications.
In no event the end of the hose shall be submerged in water.
The inner diameter of the drain duct must be at least 40 mm.
It is recommended to install a drain duct with 50 mm diameter.
Extensions must not be made on the drain hose that comes with the machine. Any extensions may cause reflux problems
in the tank.

5.3 STEAM DRAIN CONNECTION –GW6290 MODELS ONLY
The machine is fitted with double steam drain duct: the environments must be prepared to connect the drain ducts of the
machine, located at the top of the appliance.
The two ducts are equipped with rubber sleeves for connection to the external suction system.
Please note
In the event that the external air and steam venting system creates a vacuum in suction (this happens in the case of systems
with forced air extraction or in systems with venting chimneys with a high height): it is necessary to set up a chimney circuit
breaker, so as to avoid to create a depression in the washing chamber that would compromise the temperatures and therefore
the correct execution of the cycle. Contact the authorized technical assistance for information and clarifications.
