Rigid Ø200 ducted product, as per second picture par 4.3. (B) Values obtained with external air temperature of 7°C and relative humidity at 87%, inlet water temperature of 10°C and set temperature of 55°C (according to the provisions set forth in 2014/C 207/03 - transitional methods of measurement and calculation). Rigid Ø200 ducted product, as per second picture par 4.3. (C) Values obtained from average results of three tests carried out with external air temperature of 7°C and relative humidity at 87%, inlet water temperature of 10°C and temperature set according to the provisions set forth in 2014/C 207/03 - transitional methods of measurement and calculation and EN 12102). Rigid Ø200 ducted product, as per second picture par 4.3. (D) Value that ensures correct operation and eases maintenance if the product is not ducted. Correct operation of the product is nevertheless ensured up to a minimum height of 2,090 m, as long as the accessory grilles are used. (E) Outside the operating temperature range of the heat pump, heating of the water is ensured by the integration. Data collected from a significant number of products. Additional energy data are shown on the Product Sheet (Attachment A) that is an integral part of this manual. Products which do not have the label and data sheet required for boiler/solar power configurations pursuant to regulation 812/2013 may not be used in such installations. IPX4 8
