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.

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.

PERIODIC CHECKS BY THE USER

• Check the pressure of the primary circuit pressure gauge: it should be between 0.5 and 1.5 bar.

• Visually inspect, on a regular basis, the valves, connections and accessories in order to detect any leaks or malfunction.

• Periodically check the air bleed valve located on the tank top to ensure that itisnot leaking.

• Check that the DHW water circuit safety valves are in good operating condition.

• In the event of a problem, please contact an engineer or your installer.

ANNUAL MAINTENANCE

Essential instructions forthecorrect operation oftheappliance

• The discharge pipe of the safety unit must be open to the outside. If the safety unit drips periodically, it may be due to an expansion problem or clogging ofthe valve.

• For internal inspections, the hand hole can be used. If there is none, use one of the water connections to insert the appropriate inspection equipment. If necessary, drain the tank before inspection.

The annual maintenance service, performed by an engineer, must include:

• A check of the air bleed valve: the bleeding of air can lead to the need for adding water to the system.

• A check of the primary and DHW circuit pressure gauges.

• The manual activation of the storage water circuit safety valve once a year. This operation will lead to a discharge of hot water.

• A check of the correct operation of valves, taps, control units and accessories that are possibly installed [refer to the manufacturer's instructions if necessary].
