See Figure 1
1.2.- Positioning
The washing machine must be firmly secured on the floor, which will support the
its weight and the residual force generated while spinning.
After unpacking the washing machine, the pieces that secure the free-floating part
and the chassis during transportation should be removed. In order to do this, the front and
back panels should be removed to access the fixing elements. They are easily seen as they
are red.
It is advisable to secure the washing machine with the screws provided with it. In
order to do so, plastic plugs must be inserted into the previously drilled holes (Fig. 2).
The washing machine must be correctly levelled leaving a space at the back to
facilitate its maintenance.
1.3.- Water connection
If only cold water is available, water connection is carried out as shown in Figure 3.
If hot water is available, connection will be performed as shown in Figure 4. If decalcified
water is also available, connection will be performed as shown in Figure 5.
Necessary dynamic pressure: 2 ÷4 Kg/cm2.
1.4.- Steam connection
If steam is available, heating of washing water will be injected directly. The
connection diagram is shown in Figure 6.
Steam pressure: 2 ÷4 Kg/cm2.
After steam has been introduced into the machine for the first time, it is advisable
for the steam hose nuts to be re-tightened.
1.5.- Drainage
Fix the drainage bend pipe as shown in Figure 7.

7
1.6.- Electrical connection
Access the connections terminal strip dismantling the section switch and removing
its cover; fix the cable sleeve in the rear panel.
Connect the terminal strip and check that the connections correspond to the
operating voltage (Fig. 8).
Put an autonomous power switch (I) into the mains socket, with a minimum
distance between contacts of at least 3 mm.
The machine must be connected to earth.
Check that the turning direction of the drum during spinning is anti clockwise. If
this is not the case, the connections of two phases to the variator outlet should be changed
Check that the turning direction of the motor's ventilator is such that the air
circulates towards the housing of the motor. If this is not the case, the connections of two
phases to the washing machine inlet should be changed.
If the voltage frequency is 60 Hz, change the emptying valve connection.

configuration. It also gives access to detailed displays of the phases.
ADVANCE key
This key allows speeding the execution of a programme up. Every time this key is pressed,
the programmer directly moves on to the next programme stage. If the phase being carried out is
the last one, the programme ends. Furthermore, if you keep the key pressed, the programme will
advance fast.
ESC key
This key is used to remove the error messages from the screen and consider the programme
ended. It is also used to go up a submenu when the programming, maintenance and configuration
menus are accessed.

2.2.-Programme selection
When the washing turns on, the last programme carried out appears on the screen,
indicating its number and name, as well as its main characteristics. For example, if programme
number one is selected:
P1:WHITES 90 ºC
Pre-wash
Temperature: 40 ºC
START to commence
The first line on the screen indicates the programme number (P1) and its name
(WHITES/COLOUREDS 90 ºC). The first phase of the programme appears in the following
rows, in this case a pre-wash, the programmed water temperature for this phase (40 ºC) and a
message indicating how to turn the washing machine on.
2.3.-Washing programmes
These are the washing machine's 16 fixed programmes:
1.- Whites 90 ºC
2.- Whites/coloureds 60 ºC
3.- Whites/coloureds 40 ºC
4.- Whites/coloureds 30 ºC
5.- Whites/coloureds Cold
6.- Synthetics 60 ºC

Filling...
The second line indicates the ongoing phase, in this case a pre-wash. The third line shows
the programmed water temperature. Finally, the fourth line indicates the operation being carried
out at this moment; in the example, the water intake.
When the water intake has finished and the heating starts, this is indicated on the screen, as
can be observed in the following Figure:
P2:WHITES/COLOUREDS 60 ºC
Pre-wash
Temperature: 30 ºC
Heating...
After finishing heating the water, the washing time starts, indicating the remaining time on
the screen, as can be observed in the following Figure:
P2:WHITES/COLOUREDS 60 ºC
Pre-wash
Temperature: 30 ºC
Remain. time: 4 min
When the phase finishes, the drainage is performed, indicated on the screen, as can be
observed in the following Figure:
P2:WHITES/COLOUREDS 60 ºC

phase, after undergoing a drainage process.
After a few seconds, the programme continues, starting the next phase, unless the phase
being carried out when ADVANCE was pushed was the last one, in which case the
programme will end.
If the ADVANCE key is pressed during spinning, while the drum is slowing down, the
screen will display the following message:
P2:WHITES/COLOUREDS 60 ºC
Spin 500 rpm
Slowing...
9STOP key: on pressing this key we can consider the programme finished. The screen will
display the next message:
