In the feed water line:
● To protect the filter against abrasive particles, which may occur in your feed-water, such as metal- or plastic-debris or gravel, a strainer with a maximum mesh size of 300µm needs to be installed. For well water applications, a flushable prefilter between 100 to 300 µm is highly recommended.
● A pressure reducing valve must be installed if the pressure may reach values higher than 5 bar (72 psi). Caution, pressure of the public supply network can increase during the night!
● A shut off valve needs to be located upstream the UrSpring for installation and exchange of filter cartridges.
● If connected to a public water supply, a backflow preventer needs to be installed to prevent suction of water from your piping network into the community main water lines, in case of unexpected drop of pressure in the water mains.
In the filtered water line:
● A backflow preventer must be installed.
● A shut off valve needs to be located downstream the UrSpring for installation and exchange of filter cartridges.
● If there is no outlet in the filtrate line close by, to dispose the rinse water of the filter, an outlet should be installed.
