Hydraulic Installation

Transcription

1 General Norms - The safety system should be added directly to the domestic water installation. - A pressure-limiting device must be fitted in the installation. The rated pressure of the safety valve must be < 0. MPa ( bar, bar for inertia tanks). - If mains pressure is greater than 0. MPa ( bar, bar for inertia tanks), the installation of a pressure reducer is recommended to avoid exceeding the assigned pressure by more than 0. MPa (bar). - In tanks with primary circuit (tank in tank system or coil), this will must be equipped with a safety valve. - It is normal for water to be discharged during heating (expansion). The volume discharged may be up to % of the capacity of the storage tank. - Depending on the quality of the water, the pressure-regulating device should be regularly operated in order to remove lime deposits and to ensure that it is not blocked. - Water may drip out of the discharge pipe of the pressure-regulating device. This pipe should be exposed to the open atmosphere in frost-free environment and in a constant downward sloping direction. - Fit dielectric bushings at the inlet and outlet pipes at the tank connections. - Purge air from circuits once they have filled with water. The domestic can be purged by opening a hot outlet at the highest point. - To avoid ram blows in the installation caused normally by "all-none" hydraulic opening elements (electrically-operated-valve in steam warming systems, pressure kits, etc..) To avoid ram blows in the installation caused normally by "all-none" hydraulic opening elements (electrically-operated-valve in steam warming systems, pressure kits, etc..) - See additional information in the installation manual of each model. NOTE: Expansion Vessel or Vessels must be fitted in the primary (heating) circuit. This Vessel or Vessels must be sized correctly to accommodate the total water expansion capacity of the primary water in the tank and all relevant circuits.
