INSTALLATION
Screen Filter
Install add-ons (optional)
• It is recommended to install a secondary (screen) filter
on the main line, downstream from the media filtration
system.
• It is recommended to install a manual isolation valve
downstream from the media filtration system for
maintenance purposes.
24. Flatten the surface of the media.
25. Make sure that the filling port and its gasket are clear of any remaining gravel particles and close the
filling port.
19. Close all the openings of the manifold end-caps with the 2” plugs supplied with the control kit.
20 . Connect the filtration system inlet and outlet to the main irrigation line with grooved couplings.
21. Connect the backwash pipe to the backwash manifold with grooved couplings.
22. Visually check (with the aid of a flashlight) the inside of all the tanks, through the filling port, for
damaged, missing or unsecured under-drain diffusers (“flutes”). Replace, re-fit, re-connect and re-
secure if necessary.
ATTENTION
Before filling the tanks with media
Fill each tank with water up to a third of its height with a hose through the filling port adding
media, to prevent damage to the under-drain diffusers when pouring the media.
23. Fill the tanks with media through the filling port. Fill each
tank up to the media level marker on the filter tank.
