• Hot water can cause scalding!
• 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.
• The temperature of the domestic hot water can be adjusted up to 90 °C in the
boiler. However, the temperature of the domestic hot water at the drawing off
point must comply with local regulations. (E.g. in Belgium, the maximum DHW
water temperature at a drawing off point must be 75°C for boilers < 70 kW).
• 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 recommendations 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.
• Isolate the 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.
