Features Each model has a tank with doble coil, of which one specific for heat pumps with enhanced exchange surface, and a system side 80 litres puffer which function as hydraulic separator for both heated and cooled water Flexible installation Easy and clean installation Magnesium anode to ensure internal surface protection against corrosion Enamelled vitrified steel tanks to ensure high protection against corrosion Insulation made with 70 mm rigid injected polyurethane INSTALLATION INSTRUCTIONS What follows is determinant for the warranty validity. 1. The installation must: • Be executed by a qualified installer. • Be provided, where necessary, with a pressure water reducing in entrance. • Be provided with a safety valve according to the technical datas of the boiler. • Be provided with an expansion vessel (see the measuring board of the expansion vessel) proportioned to the boiler’s dimensions (it’s advised to size the expansion vessel by a thermal technician). 2. Before starting, you are invited to check the tightening of the hydraulic plug, apply torque 20 Nm. 3. The temperature of the boiler inside must always be under 95°C (70°C for the SMALVER models). 4. Each year an internal cleaning must be done. 5. In order to avoid corrosion, the anodes must be inspected after each 12 months. However, where the water is particularly aggressive, the inspections must be done each 6 months; if the anode section is less than 22 mm, it must be replaced, if covered with limestone is to be cleaned. 6. The water Langelier Index at the operating temperature, must range from "0" to "+0,4", hardness within 10°F and 25°F
