* For UK specific requirements for the discharge from safety valves, refer to «G3 Require-ments and Guidance - UK Only» on page 34SAFETY INSTRUCTIONS FOR THE INSTALLATIONEssential recommendations for safety• Install the appliance on level base made of non-combustible materials and of sufficientstrength to support its weight.• Use extreme care not to drop the boiler or cause bodily injury while lifting or mountingthe boiler onto the base. Once mounted, verify that the appliance is safely set on itsbase.• Do not use or store any flammable or corrosive products, such as paint, solvents, salts,chloride products and other detergent products near the appliance.• Make sure that the condensate outlet is never obstructed and that a condensateneutralisation system is installed if required.• Make sure that all air vents are unobstructed at all times.• In the event of small amounts of hot water repeatedly being drawn off, a stratificationeffect can develop in the tank. The upper hot water layer may then reach very hightemperatures.• Hot water can cause scalding! The temperature of the domestic hot water can beadjusted up to 75 °C in the boiler. However, the temperature of the domestic hot water atthe drawing off point must comply with local regulations.• The risk of developing bacteria exists, including “Legionella pneumophila”, if a minimumtemperature of 60°C is not maintained in both the DHW tank and the hot waterdistribution network.• In order to avoid exposure to extremely hot water that can cause serious burns, neverleave 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.• ACV recommends using a pre-set thermostatic mixing valve in order to provide hotwater at a maximum of 60°C.Essential recommendations 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 outsidethe appliance, so as to be able to shut power down when servicing the appliance orbefore performing any operation on it.• Isolate the external electrical supply of the appliance before performing any operationon the electrical circuit.• This appliance is not intended for use by persons (including children) with reducedphysical, sensory or mental capabilities, or lack of experience and knowledge, unlesssupervised or unless they have been given instruction concerning the use of theappliance by a person responsible for their safety.Essential recommendations for the correct operation of the appliance• The connections (electrical, flue pipe, hydraulic) must be carried out in accordancewith local standards and regulations in force.• The appliance must be installed in a dry and protected area, with an ambienttemperature comprised between 0 and 45°C.• Install the appliance to ensure easy access at all times.• To avoid any risk of corrosion, connect the stainless steel DHW production tankdirectly to the earth.• Make sure that the mains water used to fill the boiler has a minimum pressure of 1.2 bar.• Make sure to install a pressure reducing valve set at 4.5 bar if the mains supplypressure is in excess of 6 bar.• The DHW circuit must be fitted with an approved safety group, comprised of a 7bar safety valve, a check valve and a shut-off valve*.• If works need to be performed (in the boiler room or close to the air vents), makesure to turn off the boiler to prevent dust from entering and accumulating in theboiler heating system.General remark• If the water drawing off point is far from the tank, installing an auxiliary DHW loopcan allow to get hot water more quickly at all times.WaterMaster 25 - 35 - 45 - 70 - 85 - 120 : A1006482 - 664Y7300 • Den36ENFRNLESITDEPLRUINSTALLATION
