• The supply pressure must be between 150 and 250 kPa (1.5
to 2.5 bar).
• Fit a mechanically operated shut-off cock and filter on the
water line connecting the appliance to the water mains. Be-
fore fitting the filter, pump water through the system to expel
any ferrous particles from the piping.
Install a drainage system which ensures rapid drainage
during emptying, thereby avoiding water stagnation.

ELECTRICAL CONNECTION

• The appliance must be connected to the mains power
supply by trained personnel in compliance with current
regulations.
• Before connecting the appliance to the mains power
supply, make sure that the voltage and frequency shown
on the appliance rating plate correspond with that of the
power supply.
• The power supply cable must be flexible with
characteristics not inferior to the type with rubber
insulation H05RN-F and must be protected by a metal or
rigid plastic tube. The cable must be connected to the
terminal board as shown on the electrical wiring diagram
enclosed with the appliance, and then fastened by the
cable clamp.
• A homopolar safety cutout switch of suitable capacity and
with contact breaking distance of at least 3 mm must be
fitted upstream of the appliance. This cutout switch must
be installed near the appliance in the permanent electrical
system of the premises.
• The maximum leak current of the appliance is 1mA/kW.
• The appliance must be suitably earthed. The earth conduc-
tor must therefore be connected to the terminal (yellow-
green) on the connection terminal board.
4.2.1 INSTALLING THE POWER SUPPLY CABLE
To access the power supply cable connection terminal board,
proceed as follows:
· Remove the LH side panel and open the cover on the elec-
trical control box (Fig. 6).
· Feed the cable through cable clamp hole "I" (Figs. 1a and
1b).
· Connect the cable to terminal board "mA" (Fig. 6) and fasten
with the corresponding cable clamp.
Important: Press basket "up" button "6" (Figs. 2 and 3) to check
the direction of basket movement, or operate water turbulence
adjustment knob "7" (Figs. 2 and 3) to check for the presence
of turbulence.
If necessary, change over two of the power phases on power
terminal board "mA" (Fig. 6).
· Remount the panel and close the electrical control box.
4.2.2 EQUIPOTENTIAL SYSTEM
The appliance must be connected to an equipotential
system. The earthing conductor must therefore be con-
nected to the terminal marked "E" located near the cable
clamp.
The equipotential wire must have a minimum cross-
2
section of 10 mm
.
The manufacturer declines any responsibility for failure
to comply with existing accident prevention standards.

5. SAFETY DEVICES

(Figs. 6 and 7)
The appliance is fitted with the following safety devices:
· One 1A thermal cutout protecting the wash pump motor and
control circuit. To reset, press button "R".
· Three 6A fuses "Fb1" (aM) protecting the wash pump motor
power supply.
0270 03600
• Maximum water level control device. Only installed on ver-
sions fitted with the PLC control system (see Fig. 3). When
selector "8" is set to "AUTO", this safety device activates auto-
matic filling to restore the water level to sensor "S" (Fig. 7) .
The above components are housed in the electrical box
mounted on the front LH side of the appliance.

6. OPERATION CHECK

• Start up the appliance in accordance with the instructions
for use.
• Check the appliance for leaks.
• Using the instructions manual, explain the operation and
maintenance instructions to the user, paying particular
attention to the warnings concerning its correct use.

7. SERVICING

(Only to be carried out by an authorised installer).
All components requiring maintenance may be easily
accessed by removing the front and LH side panels.
Once a year check the:
- bearings (if worn or damaged, replace),
- rubber hoses (if damaged, replace),
- drain solenoid valve (if damaged, replace),
- actuator and in particular the articulated joints, fixings and
piston rod (if worn or damaged, replace).

8. TROUBLESHOOTING

8.1 No water turbulence inside the tank:
- Remove the LH panel and make sure pump "3" (Figs. 4 and
5) rotates in the same direction as the arrow marked on the fan
casing.
- Make sure adjustment knob "7" (Figs. 2 and 3) is set to maxi-
mum (valve fully open).
- Check whether the motor thermal cutout has tripped and, if
necessary, reconnect by pressing button "R" (Fig. 6). Also check
whether any of the power line fuses have blown.
9. REPLACEMENT OF COMPONENTS
(Only to be carried out by an authorised installer).
• Remove the LH side panel and control panel on the appli-
ance to gain access to the following components:
9.1 Electrical box (Fig. 6)
Remove the four cover fixing screws to gain access to the:
- turbulence pump fuses,
- basket actuation contactors,
- turbulence pump power supply contactor/thermal cutout,
- power terminal board,
- PLC (if installed): this device is programmed by the manufac-
turer.
- Water level control device (if installed).
9.2 Water turbulence control valve,
Basket actuator,
Turbulence pump,
Water drain solenoid valve,
Control panel components.
