4. Instructions for the installer
The following instructions are aimed at the qualified installer, to ensure that he carries out the
installation, adjustment and maintenance operations as correctly as possible and according to
current legal regulations. Any operation must be performed with electrical power cut to the
appliance.
Before using the appliance, carefully remove the special adhesive film protecting the parts in
stainless steel. Do not leave any glue residues on the surfaces. If necessary, remove them at
once, with an appropriate solvent.
Positioning - Position the appliance perfectly horizontally (the feet are adjustable) at a distance
of not less than 10 cm from the side and rear walls, to enable natural ventilating air to circulate
freely around it. The appliance is not suitable for embedding.
Electrical connection - The appliance must be connected to the electrical mains according to
current legal regulations. Before making the connection, make sure of the following:
-
the voltage and frequency values of the power supply system match the values on the
"technical data" plate affixed on the appliance;
-
the limiting valve and the system are able to support the appliance's load (see the "technical
data" plate);
-
the power supply system has an adequate earth connection according to current legal
regulations;
-
a single- pole switch with minimum between-contacts aperture of the overvoltage category
III (4000 V), sized to the load and conforming to current legal regulations, is fitted between
the appliance and the mains in the direct connection to the mains;
-
the single-pole switch used for connection is easy to reach when the appliance is installed;
-
the yellow/green earth wire is not interrupted by the switch;
-
the power supply, when the appliance is operating, must not deviate from the rated voltage
value by ±10%.
-
if the supply cable is damaged then it must be replaced by the manufacturer or by your
technical support or by a qualified person to avoid any risk.
Connection of power cable - The terminal board is on the rear panel of the appliance. Open the
terminal board cover by obtaining leverage with a screwdriver on the two side fins. Loosen the
cable gripper screw and allow the cable to pass through it. Arrange the conductors so that the
earth conductor is the last to detach from its terminal if the cable goes into a state of faulty
traction. Connect the phase conductor to the terminal marked with the letter "L", the neutral
conductor to the terminal marked with the letter "N" and the earth conductor to the terminal
marked with the symbol
. Tighten the ring-nut of the cable gripper and close the terminal
board cover. The appliance must be connected to an equipotential system whose efficiency
must first be checked according to current legal regulations. This connection must be made
between different appliances by using the appropriate terminal marked with the symbol . The
equipotential conductor must have a minimum diameter of 2,5 mm
2
The equipotential terminal
is at the rear of the appliance.
Connection to water mains -The appliance must be supplied with softened drinking water with
a hardness value of 0,5°F to 3°F (It is obligatory to use water softener to reduce the formation
of scaling inside the proofing chamber). The water pressure must be in the range of 100 to 200
kPa (1,0 – 2,0 bar).
The connection to the water supply is done using the 3/4” threaded solenoid valve on the back
(at the bottom) of the appliance, fitting a mechanical filter with a cut-off cock (before
connecting the filter, allow a certain amount of water to flow out in order to remove any waste
from the pipe).
