4.ELECTRICAL CONNECTION
● The appliance must be connected to the mains power supply
in compliance with current regulations.
● Before connecting the appliance to the mains power supply,
make sure the voltage and frequency shown on the appliance
rating plate correspond with that of the power supply.
●
The appliance must be connected following the instructions
shown in the enclosed electrical diagram with the phase wires
(L) and neutral (N) connected as indicated on power cable.
● The appliance must be permanently connected to the mains
power supply using an H05 RN-F type cable. The power supply
cable must be protected by a maetal or rigid plastic tube. If the
appliance is connected using an existing cable, do not insert the
installation tube in the appliance. Also make sure the tube has
no sharp edges.
● An isolating switch of suitable current raiting with a contact
bearking distanceof at least 3 mm, and a 16 A delayed-action
T type fuse must be fitted upstream of the appliance. The
isolating switch must beinstalled near the appliance in the
permanent electrical system of the premises.
● A devices (interlocked plug, lockable switch or similar devices)
lockable in the open position during mainenance must be
installed ahead of the appliance.
● The appliance must be suitably earthed. The earthing conduc-
tor must therefore be connected to the terminal marked by the
symbol on the connection terminal board.
The appliance must also be connected to an equipotential
bonding system.
The equipotential wire must have a minimum cross-section of
10mm

5. WATER MAINS CONNECTIONS
(Refer to the installation diagrams at the beginning of this
handbook).
Fit a mechanical fitler and shut-off cock between water inlet
pipe
“W” and the mains water supply. Before connecting the
fitler, run off a certain amount of water to remove any ferrous
particles from the piping.
● The water inlet must be connected to a drinking water supply
with pressure of 150-250 kPa (1.5-2.5 bar)
5.2
WATER DRAINAGE SYSTEM
Removing for dirty water and oily inside the oven cabinet there
is a collection pan under the oven. This pan should be cleaned
periodically by the user.
6. GAS CONNECTION
6.1 WARNINGS
● Make sure the appliance corresponds with the gas supply to
which it is connected. If the appliance does nor correspond
with the gas supply, convert following the instructions given in
section 7 below (“Conversion to different type of gas”).
● The gas connection fitting is signed yellow color.
● Before installing the appliance, contact the local gas supplier
to check the compatibility of the gas supply with estimated
consumption.
● Before connecting the appliance to the gas line, remove the
plastic cover from the gas connection on the appliance.
● A rapid-action gas shut-off valve must be fitted upstream of
the appliance in an easily accessible position.
● Once the appliance has been installed, test for gas leaks at the
connection points using a soapy water solution.
● Do not modify the aeration supply necessary for
combustion.
● Following connection to a different gas supply, carry out the
operation test described in section
9 (“ Operation test ”).
6.2 RATED THERMAL POWER
Refer to “ Technical Data ” Table 1 for details about the rated
thermal power. The rated thermal power is defined by the gas
inlet pressure and the diameter of the burner injectors. The
rated thermal power must always be tested by an authorised
installer or the local gas supplier when installing a new
appliance, converting an existing appliance to different gas
supply or when servicing the appliance.
Do not readjust the rated thermal power after this check.
6.3 TESTING THE GAS INLET PRESSURE
(Figs. “10a”)
The inlet pressure is measured upstream of the gas control
valve with the appliance operating (after eventual conversion
to a different gas supply) using a
pressure gauge with minimum
resolution of 0.1 mbar . To measure the gas inlet pressure,
proceed as follows:
1)
Open the control panel. Remove sealed bolt “C”
from the pressure point and connect the pressure
gauge pipe.
2)
Make sure the pressure reading corresponds with the
values shown in the table below:
GAS TYPE
Natural gas G20
L.P.G. G30/G31
If the inlet pressure does not correspond with the above
values, the appliance will not function.
If this is the case, contact your local gas supplier immediately
3) Once the inlet pressure has been measured, stop the
cooking cycle and close the gas shut-off cock.
4) Disconnect the pressure gauge and retighten sealed bolt
“C”.
5) Close the appliance.
