SAFETY INSTRUCTIONS
General remarks
• Connections (electrical, hydraulic) must be carried out in accordance
with applicable standards and regulations, by an approved installer.
• The start-up and commissioning must be carried out by an approved
installer.
• If the water drawing off point is far from the tank, installing an auxiliary
DHW loop can allow to get hot water more quickly at all times.
Essential instructions forthecorrect operation ofthesystem
• The appliance must be installed in a dry and protected area.
• Install the appliance to ensure easy access at all times.
• Before fixing the appliance to the wall, make sure that the wall can bear
the weight of the appliance filled up with water.
• In the case of hydraulic connection to a water system made of brass, it
is compulsory to use reduced dielectric sleeves or equal male-female
sleeves made of malleable cast iron. Should the thread of the tubes,
which are not provided with such sleeves, be attacked by corrosion, our
warranty will be void.
• Make sure to install a pressure reducing valve set at 4.5 bar in the DHW
circuit if the supply pressure is higher than 6 bar.
• Do not expose the appliance to pressure exceeding 7 bars, otherwise
the appliance will suffer irreparable damages. Install an approved safety
group, comprised of a safety valve set at 6 bar, a check valve and a stop
valve.
• Make sure that the outlet of the safety unit goes directly to the sewer to
avoid any potential damage and that the drain pipe is never obstructed
and protected from freezing.
• Do not install the safety group above the tank to avoid water discharge
on to the appliance.
• If one or several mixing valves are used, a check valve is to be mounted
to the cold water column supplying the mixing valves. A stop valve must
be installed on the cold water supply of the appliance.

Essential instructions forthe safety of persons and the environment
• ACV recommends using apre-set thermostatic mixing valve in order to
provide hot water at a maximum of 60°C.
• In order to avoid exposure to extremely hot water that can cause serious
burns, never leave children, old people, disabled or handicapped people
in the bath orshower alone.
• Never allow young children to turn on the hot water or fill their own bath.
• Adjust the water temperature in accordance with usage and plumbing
regulations.
• The risk of developing bacteria exists, including “Legionella
pneumophila”, if aminimum temperature of 60°C is not maintained in
both the DHW tank andthe hot water distribution network.
Essential instructions for the electrical safety
• Only an approved installer is authorized to carry out the electrical
connections.
• Make sure that the appliance is connected to the earth.
• Install a 2-way switch and a fuse or circuit breaker of the recommended
rating outside the appliance, so as to be able to shut power down when
servicing the appliance or before performing any operation on it.
• Shut down external electrical supply of the appliance before performing
any operation on the electrical circuit.
• This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless supervised or unless they have
been given instruction concerning the use of the appliance by a person
responsible for their safety.

PACKING CONTENTS
PRINCIPLES OF OPERATION
This closed-system appliance is
intended to produce hot water in
households and institutions.
The hot water can be used for both
sanitary and consumption purposes.
The water temperature of the appliance
can be adjusted depending on your
needs (65 °C).
The installation of a safety group is mandatory, but the safety group IS
NOT part of the delivery.
After having achieved the adjusted or
preferred temperature, the temperature
regulator switches o the heating
automatically. In this way there is hot
water in the appliance for a long time.
The insulation in the internal tank
prevents the fast cooling of the hot
water, therefore, the water remains
hot for a long time. Hot water flows out
without mixing with cold water.

Installation
CONNECTING THREE-PHASE
APPLIANCES
This procedure is to be carried out by an
approved electrician:
1. Connect using four conductors of
2.5 mm2, (one green/yellow for the
earth.)
2. Connection to the mains via termi-
nals B1, B2 and B3 of the thermo-
stat (see "Figure 3" to "Figure 5",
page 17).
3. Connect green/yellow conductor
to terminal
4. For a 400 V Tri supply without
neutral, modify the internal con-
nections by following the wiring
diagram in "Figure 3", page 17.
5. Regarding a 230 V Tri connection,
see diagram in "Figure 4", page 17.
CONNECTING SINGLE PHASE
APPLIANCES
This procedure is to be carried out by an
approved electrician:
1. Use three conductors of 2.5 mm2,
(one green/yellow for the earth).
2. Connect to the mains via terminals
A and B or 1 and 2 of the thermo-
stat (see page 16).
3. Connect the green/yellow conduc-
tor to terminal
Essential instructions for the electrical safety
• The protection class of the appliance is: I.
• The covers closing the electric group provide protection against the
involuntary touching of the active electric parts under voltage.
• Connection to the mains is to be carried out in accordance with the
installation diagram found in this installation manual and on the plate
at the bottom of the appliance, by paying attention to the connection
to the correct phases.
• It is FORBIDDEN AND DANGEROUS to start-up the appliance without
the professional installation by a specialist provided with protection
against the electric contacts.
• For the correct operation of the appliance, we recommend the use of a
protection relay in the mains of your building.
• CAUTION! Before doing any maintenance or repair tasks, disconnect
the appliance from the electric supply. The maintenance and repair
works have to be carried out by qualified personnel.
• After repair and maintenance works, the appliance has to be restored
to its original condition.
• The repair works must be documented by the technician in order to
preserve the validity of the warranty.
