NOTES
• This manual contains important information with respect to the installation, the starting up
and the maintenance of the hot water tank.
• This manual must be provided to the user, who will read it carefully and keep it in a safe
place.
• The availability of certain models as well as their accessories may vary according to the markets.
• The manufacturer reserves the right to change the technical characteristics and features of
its products without prior notice.
We accept no liability should any damage result from the failure to comply with theinstruc-
tions contained in this technical manual.
Essential instructions forthe safety of persons and the environment
• It is strictly prohibited to bring any modification to the appliance, without
themanufacturer’s prior written approval.
• The appliance must be installed by a qualified installer, in accordance with
applicable regulations.
• The installation must comply with the instructions contained in this manual and
with the regulations applicable to installations.
• Failure to follow the instructions in this manual could result in personal injury or a
risk of environmental pollution.
• The manufacturer declines all liability for any damage caused as a result of

SAFETY INSTRUCTIONS
General remark
• Connections (electrical, hydraulic) must be carried out in accordance with
applicable standards and regulations.
• 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installation
• The tank must be installed in a dry and protected area.
• Install the appliance to ensure easy access at all times.
• To avoid any risk of corrosion, connect the stainless steel tank directly to the earth.
• 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.
• On the DHW circuit, install an approved safety group, comprised of a safety valve
set at 7 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.
• Do not install the safety group above the tank to avoid water discharge on to the
tank.

INSTALLATION

Essential instructions forthe safety of persons and the environment
• Hot water can burn!
In the event of small amounts of hot water repeatedly being drawn off, a
stratification effect can develop in the tank. The upper hot water layer may then
reach very high temperatures.
• ACV recommends using apre-set thermostatic mixing valve in order to provide
hot water at a maximum of 60°C.
• Water heated to wash clothes, dishes and for other uses can cause serious burns.
• 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.
• 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
All appliances are delivered, tested and packaged separately.
General Remark
• The hot water tank may be installed either on the floor or on a wall using the
provided wall-mounting kit (depending on the model).
Essential instructions for the correct operation of the installation
• When hung on a wall, the SLEW models must be assembled with the heating
element to the bottom (DHW pipes to the bottom).
• In horizontal configuration, the peak output and the first hour continuous output
will be reduced. In this case, we recommend to oversize the tank.

Essential instructions forthe safety of persons and the environment
• Refer to the safety instructions for the installation. Failure to comply with these
instructions can result in damages to the installation, severe injuries or death.
• Hot water can burn! ACV recommends using a pre- set thermostatic mixing valve
in order to provide hot water at a maximum of 60°C.
Essential instructions forthecorrect operation oftheinstallation
• The filling circuit of the DHW tank must be equipped with a safety group,
comprised at least of a stop valve, a check valve, a safety valve set at 7 bar, and
possibly, an expansion vessel of the appropriate size. Make sure that the circuit
between the tank and the safety valve is always open.
• The third DHW tank connection, if any, can be used for the auxiliary DHW loop.
If the connection is not used, replace the protective plug by a brass plug of the
appropriate size.
General remarks
• In certain countries the domestic kits must be approved.
• The circuit illustrations are basic principle diagrams only.
