• Connection to the drainage network
The drainage of appliance "1" must go to an open type of
receiving drain-trap "2" so there is no contact between the
two.
5.3.3 - Electrical connection
• Before connecting, check that both the voltage and frequency
of the supply network matches the operating data on the
rating plate.
• Connection to the electricity line must include the
installation of a circuit breaker of a suitable capacity with an
opening distance between the contacts of at least 3 mm.
In addition, when the appliance is working, the supply voltage
should not vary from the rated voltage by ± 10%.
• The characteristics of the flex for connecting to the
electricity line should be at least equal to the HO7RN-F type
with rubber insulation and its nominal cross section should
be adequate for the maximum current input.
• It is essential to connect the appliance to an effective earthing
system. For this purpose near the connecting terminal block
there is a terminal marked with the symbol PE to which the
earth wire must be connected. This earth wire must comply
with the applicable standards. there is a terminal marked with

5.3.4 - Equipotential connection

• It is essential to connect the appliance to an equipotential
system. Use the setscrew marked with the symbol for this
connection.
• The cross-section of the equipotential wire must be 10 mm
• The building's earthing and equipotential systems must
conform to the laws in force and be checked periodically.
• The manufacturer is not liable if these accident prevention
rules and regulations are disregarded.

5.3.5 - Installing the power lead

6 - CHECKING OPERATION

For the version with a hydraulic unit:
ATTENTION!
Once the electrical connection has been made check
the rotation direction of the pump motor:
• Lift the lid up completely and press the "P" lift push
button very briefly.
The motor should turn in the direction indicated by
the arrow on the fan casing (Fig. 6).
• If the motor is turning in the opposite direction,
reverse two wires of the three-phase electrical
connection and check again.
For the version with an actuator:
• Check that the appliance oves up that when pressing the "P"
button. If it doesn't, reverse the phases.
• Start the appliance according to the instructions for use.
• Check the setting of the safety valve.
• Check lid balance.
• Instruct the user about how to use and service the appliance
with the aid of the instruction booklet, explaining exactly
what has to be done to use it correctly.

7 - MAINTENANCE

• All components needing maintenance can be accessed after
removing either the control panel or front panel.

7.1 - Some malfunctions and their solutions

• Some malfunctions can occur even when the appliance is
used normally
Heating up is slow or not enough
• Eliminate the accumulation of air in the jacket: press the
depression valve push button "I" letting off some bursts of
steam.
• Check supply voltage.
• Check the condition of the heating elements.
Not heating
• Check supply voltage.
• Check if the safety thermostat has tripped (TS1) (push
button "U").
• Check the condition of the heating element (RS1); wiring
diagrams enclosed.
• Check contactor operation (KM1-KM2-KM3); wiring
diagrams enclosed.
• Check integrity of the fuses QS5.
For the version with a hydraulic unit:
When the push button is pressed,the pot does not tip.
Possible causes:
• Absence of oil, overheating or impurities in the oil in the
hydraulic unit.
