The upper heating element 2
enables only a limited amount
of water (H) to be heated.
Thissystem givesyou asmaller
amount of hot water (about
20 ÷ 30% of the total capacity)
in a shorter time thus reducing
consumption.
Use the “BOOSTER” key for
this function.
The temperature in area His preset to the maximum thermostat temperature setting
and is controlled by means of the changeover switch thermostat probe 7. When normal
running operations are set (“NORMAL”total heating), the lower water heating element 1
switches on so that all the water inside the appliance is heated (H+L).
Water temperatureis controlled bytheoperational thermostat8according to theposition
of the adjustment knob (fig. 5).

• Use pipes that will resist operative pressure as well as hot water tempera-
tures that can normally rise to and even exceed 80°C to connect the water
heater intake and output.It is inadvisable, therefore, to use materials that will
not withstand this kind of temperature.
• Screw a pipe connection Kon to the appliance water inlet Imarked with a
blue ring.
• A tap Bto empty the water heater must be screwed on one side of the pipe
connection. A special tool must be used to turn this tap. A safety valve A
supplied with the appliance must be screwed on to the other side of the con-
nection.
• Connect the latter to the mains cold water pipe by means of a hose pipe F.
Also install a drain pipe Cto be used if the tap Bis opened.
• When the safety valve is screwed on, take care not to force it as far as it will
go and do not tamper with it.
A slight drip is normal during heating; we therefore advise you to connect the
valve to a drain by means of a small pipeE.A discharge pipe E connected to the
pressure relief device is to be installed in a continuously downward direction
and in a frost-free ambient.
If the mains pressure should be similar to the valve pressure setting, a pressure
reducer should be installed as far away as possible from the appliance.
• Fill the water heater and make sure there are no leaks.
• In order to empty the water heater close the main intake tap, open the hot
water tap and the drain tap B.

The appliance must be connected to the
mainssupply bymeansofa differentialtwo-
pole magnetothermal switch (30 mA) in
compliancewiththe currentIECstandards
(contact opening of at least 3 mm, prefer-
ably equipped with fuses), or by means of
the plug.
This switch must be used each time the
appliancehasto be disconnectedfromthe
mains supply.
The appliance is equipped with an H05VV-F
tipe cable with a cross-section of 3x1,5 mm
2
,
and a diameter of 8,5 mm.
The yellow-green earth wire must be
slightly longer than the phase wires.
Before start-up make sure that the mains
voltage is the same as the value marked
on the appliance rating plate.
5.3 WIRING
5.4 USEFUL INFORMATION
If, after a certain period of time, no hot water comes out of the taps, before contacting
your Technical Assistance Service make sure that the plumbing and electrical wiring is
as described in the relevant paragraphs.
If the electricity is cut off to the lower heating element, the amount of hot water available
is 20 ÷ 30% of the total capacity ("BOOSTER" running).
You should still contact yourTechnical Assistance Service.
The level of water hardness must never fall below 12° FR for the galvanic protection
system to work well.
15
• Open the main tap of your home water supply as well as the hot water tap until all the
air has come out of the appliance; when only water starts to come out, close the hot
water tap.
• Make sure there are no leaks.
• Insert the plug into the mains and switch on the machine; if the appliance has a wall
control panel, turn the switch to I(ON).
