ECO FVT hydraulic connection
The softener is now ready to be installed.
Place the softener in a suitably hygienic location.
The device must be placed on a flat floor.
Devices should be protected against freezing, general humidity and heat sources (max. 40 °C). They must be
hydraulically connected as shown in Fig. 2, by connecting the hard water inlet and softened water outlet as the
arrows show on the valve.
Connect to the drain located at the rear of the device (see Fig. 2).
The drain tube must be visible and allow inspection. Breaks in the drain tube and funnel-shaped drain collection
sump must be provided for (see Fig. 2).
The funnel-shaped drain collection sump must not be higher than 1.5 m above the floor.
The drain tube must be no longer than 4 m and must not create any significant flow limitations
(see Fig. 2).
Connect the overflow to one of the two arrangements on the rear part of the cabinet, inserting the tube into one
and plugging the one that is not used with a suitable plug (See Fig. 2 pos. 7 and 8).
