Hydraulic Installation General Norms - The safety system should be added directly to the domestic water installation. - A pressure-limiting device must be fitted in the DHW installation. The rated pressure of the safety valve must be < 0.8 MPa (8 bar, bar for inertia tanks). - If mains pressure is greater than 0. MPa ( bar, 4 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 3% 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 DHW 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.

Recommendations for handling electrical equipment: Before touching the connection means, ensure that all connection circuits are totally disconnected from the mains power supply. Installation, configuration, start-up and maintenance of the heating elements must only be carried out by an authorised electrical fitter. All current rules, standards and regulations must be complied with. The tanks must be equipped with a DHW temperature control thermostat (maximum 80 ºC) and an all-pole limiting thermostat. The sensors must be positioned higher than the electric heating element. Inertia models must be equipped with a temperature control thermostat (maximum 8 ºC) and an all-pole limiting thermostat. Suitable safety devices should be installed (temperature safety, level safety for heating liquids by natural convection, flow safety in the case of fluids in circulation, etc.). The elements must be connected to the mains by means of a power contactor, never directly. The installation should be protected by means of an automatic all-pole switch, with a separation of 3 mm or more between contacts, as well as automatic electric protection systems. It is the user s responsibility to ensure that the basic requirements of the European Low Voltage Directive are complied with. Electric heating elements generate high temperatures. It is advisable to take precautions to ensure the protection of goods and persons against the risk of fire or accidental burns during operation and following the disconnection of the equipment or installation. 43

Permanent cathodic protection, GX tanks Lapesa Correx-up for domestic GX tanks 2 2 3 4 In areas with particularly hard water (chloride content is a significant reference parameter), the storage tank should be fitted with a cathodic protection system. Although the health authorities define the limits of water chloride content as 0 mg/litre for drinking water, the cathodic protection system for the storage tank should be installed when the chloride content is mg/litre or greater. All GEISER EUROPA storage tanks can be fitted with the LAPESA correx-up permanent cathodic protection system, which is totally automatic and maintenance-free. It basically comprises a titanium anode () mounted on the connection plate (2), and, if required, on the side plate (3), depending on the storage tank model, this anode is connected to a potentiostat (4) which automatically regulates the storage tank input current through the leads () WARNINGS!!! - Use original wires only, without lengthening or shortening them as this could cause corrosion due to the possibility of reverse polarity. Use a socket base near to the storage tank for this purpose. - The protection anode comes into operation when the tank is full of water. When the tank is empty, the control light () flashes red. - If the control light () is green, this shows that the tank is receiving a protective current. If the control light is not on or is red and flashes, check the connections, contacts and mains supply. If this anomaly continues, notify the fitter or our Technical Service Department. - In the case of vertically installed tanks, when water is not going to be extracted for periods of over 3 months, we recommend fitting an automatic drain valve at the DHW outlet. - If the tank is installed horizontally, we recommended taking water out at least every 3 months. - The potentiostat (4) and the connection wires () must not be disconnected, except to empty the tank. - Do not disconnect the protection system during holidays, etc. - Occasionally check that the control light () is working correctly. 84
