In particular, hand this instruction manual to the users, informing them that is must be kept near the product at all times. Inform potential users that the following actions must be carried out: – Periodically check the system water pressure. – Restore system pressure, by deaerating the system when necessary. – Adjust the setting parameters and the adjustment devices to optimise operation and reduce the system’s operating costs. – Perform regular maintenance, as envisaged in the standards. 4.12.1 Filling the system Check the water pressure on the pressure gauge regularly and make sure that the pressure is between 0.5 and 1.5 bar when the system is cold. If the pressure is below the minimum value, it must be increased through the filling cock. Close the cock once the average value of 1.2 bar has been reached. The maximum pressure of the heating/cooling system is 3 bar. a a The installation, initial start up, and configuration must be carried out in accordance with the instructions, by a qualified technician only. The manufacturer declines all responsibility for damages caused to people, animals or possessions following incorrect installation of the appliance. If frequent fillings (once a month or more frequently) are required for your system, this indicates a potential problem with the installation (leaks, expansion vessel problems). Contact your trusted installer to analyse and solve the problem quickly, and to prevent damage caused by corrosion of the components due to excessive water replacement in the system. 4.1 Initial start-up a To guarantee safety and correct operation of the system interface, it must be commissioned by a qualified technician in possession of the skills as required by law. 4.1.1 Start-up procedure – Insert the system interface on the connection slide pushing it gently downwards.
