Introduction Dear Madam, Dear Sir, thank you for choosing the NIMBUS COMPACT UK M NETR32 ARISTON system. This manual was drawn up with the aim of informing you on how to install, use and maintain the NIMBUS COMPACT UK M NETR32 system, in order to enable you to optimally use all the functions. This installation manual along with the user manual should be left with the product after installation for future reference. Store this booklet, as it contains all the necessary information regarding the product following its initial installation. To find the nearest Technical Assistance Service and to consult the multimedia copy of the documentation, you can connect to the Internet website www.ariston.com. Please also refer to the Warranty Certificate that you will find inside the packaging, or which was handed to you by the installer. Symbols used throughout this manual and their meaning i a Warranty WARNING Indicates important information and particularly delicate operations. WARNING: DANGER Indicates actions that, if not performed correctly, can lead to general injuries or malfunctions or material damages to the appliance; they therefore require special attention and adequate training. The ARISTON product is covered by a conventional warranty, which takes effect from the date of purchase of the appliance. For the warranty conditions, refer to the warranty certificate accompanying the product. Compliance The CE marking applied to the appliance certifies that it conforms with the essential requirements of the following European Directives: – 2014/30/EU (Electromagnetic Compatibility Directive) – 2014/35/EU (Low Voltage Directive) – RoHS 3 2015/863/EU on restrictions regarding the use of certain hazardous substances in electrical and electronic appliances (EN IEC 63000:2018) – Regulation (EU) no. 813/2013 relative to ecodesign (no. 2014/C 207/02 - transitional methods of measurement and calculation) – 2014/68/EU (PED) The UKCA marking applied to the appliance certifies that it conforms with the essential requirements of the following Regulations: – Electrical Equipment (Safety) Regulations 2016 (S.I. 2016 No 1101, as amended) – Ecodesign for Energy-Related Products and Energy Information Regulations 2019 (S.I. 2019 No 539, as amended) – Pressure Equipment (Safety) Regulations SI 2016 no. 1105, as amended – Electromagnetic Compatibility Regulations 2016 (S.I. 2016 No. 1091, as amended) – The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (S.I. 2012 No. 3031, as amended) According to BS EN 12897:2016, the product complies with the following requirements. – The Building Regulations 2010 (S.I. 2010 No. 2214), as amended – The Water Supply (Water Fittings) Regulations 1999 (S.I. 1999 No. 1148), as amended Disposal PRODUCT CONFORMING TO: – EU DIRECTIVE 2012/19/EU – Italian Legislative Decree 49/2014 pursuant to Art. 26 of Legislative Decree no. 49 of 14 March 2014, “Implementation of Directive 2012/19/UE on waste of electrical and electronic equipment (WEEE)” – UK Waste Electrical and Electronic Equipment Regulations 2013 S.I. 2013 No. 3113 The barred wheeled bin symbol appearing on the appliance or on its packaging indicates that the product must be collected separately from other waste at the end of its useful life. The user must therefore deliver the decommissioned product to an appropriate local facility for separate collection of electrotechnical and electronic waste. Alternatively, the appliance to be scrapped can be delivered to the dealer when purchasing a new equivalent appliance. Proper separated collection of the decommissioned appliance for its subsequent recycling, treatment and eco-compatible disposal helps to prevent negative effects on the environment and human health, besides encouraging reuse and/or recycling of its constituent materials. 2 / EN
