Installer Manual Fleck 5600 - SXT - System sizing Note This value does not correspond to the brine draw flow rate but to the total flow rate passing through the injector. Then refer to the injector diagrams for the chosen tank size and at the inlet pressure in order to check if the injector will give a correct flow rate.
Page 31
Installer Manual Fleck 5600 - SXT - System sizing Note Multiply the amount of salt in kg by 3 to get a approximation of the brine volume to draw. To calculate slow rinse duration: The volume of water to be used for slow rinse is given in the resin manufacturers specifications. Generally speaking, it is advised that between 2 and 4 BV of water is used to perform the slow rinse after brine draw.

Installer Manual Fleck 5600 - 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 5600 - SXT - Installation • When installing the water connection (bypass or manifold) first connect to the plumbing system. Allow heated parts to cool and cemented parts to set before installing any plastic parts. Do not get primer or solvent on O-rings, nuts, or the valve.
Installer Manual Fleck 5600 - SXT - Installation • The riser tube should be cut flush with the top of the tank. Slightly bevel the ridge in order to avoid deterioration of the seal whilst fitting the valve. • The drain line must be a minimum of 12.7 mm (½") in diameter. Use 19 mm (¾") pipe if the backwash flow rate is greater than 26.5 lpm (7 gpm) or the pipe length is greater than 6 m ...
Installer Manual Fleck 5600 - SXT - Installation 5.5.1. Top-mounted valve installation When pressurized, any composite tank will expand both vertically and circumferential. In order to compensate the vertical expansion, the piping connections to the valve must be flexible enough to avoid overstress on the valve and tank.
