INSTALLATION
PACKAGE CONTENTS
The appliances are delivered assembled, tested and packed.
At product reception and after removal of packaging,
check the package contents and that the appliance is
free of damages.
Contents packaging :
• A domestic hot water tank.
• A technical manual
TOOLS REQUIRED FOR THE INSTALLATION
General remarks
Make sure to place the rating plate on the outer casing of the tank, so that it is easily
accessible and readable.
The manufacturer reserves the right to change the technical characteristics and
features of its products without prior notice.
The availability of certain models as well as their accessories may vary according to
the markets.

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.

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.

SAFETY INSTRUCTIONS TO FILL THE TANK
Essential instructions forthe safety of persons and the environment
• The DHW tank must always be filled and pressurised before filling and pressurising
the primary circuit.
• Do not use vehicle antifreeze. This can causeserious injury or death, or damage
facilities.
• If antifreeze is needed in the primary circuit, it must comply with Public
Hygiene Regulations and must be non-toxic. A food-grade Propylene Glycol is
recommended. It must be diluted according to the ratio recommended in the local
regulations.
• Consult the manufacturer to determine the compatibility of the antifreeze with the
tank's construction materials.
Essential instructions forthecorrect operation oftheinstallation
• Before bringing the tank into service, check the connections to avoid any risk
ofleaks during filling.
• Only use drinking water to check that the DHW tank is watertight. The on-site
testpressure must not exceed a pressure surge of 8,6 bar.
• Using antifreeze in the primary circuit will lead to a reduction in the heating
performance. The higher the concentration of antifreeze in the circuit, the lower
the performance.

STARTING UP

FILLING THE DHW TANK Figure 1
General remark
• Connect the safety valve outlet to the sewer.
1. To fill the tank, open a hot water tap (2) located at the highest point of the installation. It
enables to bleed the air from the installation.
2. Open the filling valve (1) and the stop valves (3) to fill the DHW tank.
3. Close the hot water tap (2), after the water flow has stabilised and the air has been
completely evacuated.
4. Check all the connections of the installation for leaks.
FILLING THE PRIMARY CIRCUIT Figure 2
General remark
• If the tank is used within a heating installation, refer to the heating boiler manual.
1. Check that the drain valve (3) of your primary circuit is tightly closed.
2. Open the stop valves (1) and (2) of the primary circuit connected to the heating boiler.
3. Open the air bleed valve (4) located on the top of the hot water tank.
4. When the air is eliminated, close the airbleed valve (4). Make sure the air bleed valve is tight.
