Installation inspection of the
reference machine
Before carrying out any major test series inspect
the installation and check the following terms:
• Themachinemustbeinstalledonalevel
base. The following clearances are recom-
mended in order to facilitate calibration:
At least 500 mm between the machine and
the wall behind and min. 50 mm on both
sides of the machine whether installed next to
the wall or other machines.
• Checkthelevellingofthemachine.Theverti-
cal difference from corner to corner of the top
lid shall not exceed 5 mm. If not adjust the
feet of the machine.
• Themachineshallbeconnectedusingthe
supplied Y hose or using two single hoses.
• Thewaterhoseandpowercablemusthang
freely between the machine and wall in order
to prevent disrupting the reference machine
scale system.
• Makesurethatthedraininstallationismade
according to the information on next page.
Observe the required air gap in the drain sys-
tem.

Drain connection
• Connect a 75 mm (2 1/2") flexible rubber hose
to the machine’s drain pipe, ensuring a down-
ward flow from the machine. Avoid sharp
bends, which may prevent proper drainage.
• There should be an air-gap of 50 mm between
the drain hose and the drain.
• Make sure that the drain hose is sufficiently
flexible so that it does not cause problems
related to the scale system.
• Pipes made from PVC or similar materials
may not be connected to the machine due to
the load cells.
• The drainage hose should be located over a
floor drain, drainage channel or similar so that
the distance between the outlet and the drain
is at least 25 mm (1").
• Checkthattheamountofsupplywateratthe
water connection to the reference machine is
sufficient and compliant with the specifica-
tion in the standard (15 ± 2 litre) and that the
amount can be maintained at all times. The
water pressure at the intake of the machine
may never fall below 100kPa.
• Checkthatthepowersupplyiscompliantwith
the voltage specified on the reference machi-
ne data label and within the tolerances of the
standard (± 2%) .
• Makesurethatthepowersupplycanmaintain
the required voltage level whilst the reference
machine is heating.

Calibration of the level control
system
During testing compliant with the IEC 604456
Ed5 standard, this calibration does not control
the supply water values of the wash program.
However, where wash programs use the scale
for controlling the water intake level, the control
becomes active and manages other levels inside
the machine such as empty machine, heating
element safety level and overfill. These levels
are needed for the safety values of the machine.
Therefore, the level must be adjusted and main-
tained in accordance with the procedure descri-
bed below.
Assembling the ruler
Fig. 1-2: Mount the scale and ruler as shown in
the pictures.

Calibration of level control system
The level control system can be calibrated both individually and manually.
Calibration starts at the bottom of the inner drum and can go up to 250
mm from that point.
A ruler is supplied with the machine with which the water level above the
inner drum can be read.
• Placetheruleronthebottomoftheinnerdrum,equidistantbetweentwo
lifters and front and rear gables. Rotate the drum so that the ruler is fully
vertical and ensure that the three pins of the ruler fit in the holes of the inner
drum.
• Pushthescaletothebottomofthedrumandtightenthenuts.
 • Closethedoor.

Calibration of the scale system
Wascator FOM 71 CLS
Calibration of the scale system
After installation, and once all hoses and electrical cables have been
connected to the machine, the scale must be calibrated. The current
calibration (Weight vs scale output) is factory-set and a zero calibration
is required in order to compensate for the additional weight of the cables
and hoses. Important: The cables and hoses must hang freely and the
drain must have an air gap in order to ensure that the scale functions
properly. See chapter: Installation.
Zero calibration is almost identical to a Tara, but with one big difference. In
a Tara, the scale will be zero adjusted, although the adjustment will be lost
when the power is switched off. In a Zero calibration, the adjustment will
be saved.
Additional calibration variants may be selected in Service mode, but they
do not apply to the CLS version.
If a weight transducer need to be replaced, or if the scale electronics are
changed, a complete calibration of the scale is required. Please consult
an Electrolux Laundry System Service Centre before performing such a
calibration.

5:2 Calibration of the scale system
Zero adjustment of the scale (weight function)
The scale is factory-set and no adjustment should be necessary unless
some components have to be replaced. However, a zero adjustment must
be carried out as the total weight of the machine has to be programmed
into the scale.
Make sure that the water and drain hoses are in place and properly moun-
ted. Make sure that all panels are fitted and the power connection is loca-
ted on top of the machine.

• Godownto”Exit”
• Press”Select”
• Gobacktothemainmenu.
The zero adjustment is now complete and the weight of the emty machine
should now be shown in the display as 0.0 kg (a margin of ± 0.1 kg is
permitted). If a different value is shown in the display, the zero adjustment
must be done again.
