Installer Manual Fleck 5800 - SXT - Installation Installation Mandatory It is strictly forbidden for not qualified personal, to accede to system’s internal parts to perform any kind of technical action. Be sure to disconnect the electrical power, close the water inlet and depressurize the system before opening the front cover to access internal parts.
Installer Manual Fleck 5800 - SXT - Installation 5.3.2. Water • Water temperature must not exceed 43°C. • A minimum of 1.4 bar (dynamic pressure on injector) of water pressure is required for the regeneration valve to operate effectively. Mandatory Do not exceed a maximum of 8.6 bar inlet pressure.
Installer Manual Fleck 5800 - SXT - Installation • It is not recommended to use sealants on the threads. Use PTFE (plumber’s tape) on the threads of the drain elbow, and other NPT/BSP threads. • The installation of a prefilter is always recommended (100μ nominal). •...
