INSTALLATION — OVERVIEW The softener installation involves the elements listed and pictured here below. Please refer to the Scope of Delivery sheet, which specifies which elements are delivered with your softener.

It is under the installer’s responsibility to make sure that the installation does not generate any water hammer which could damage the proper work of the softener. Our softeners are equipped with a check valve on the water inlet connection flange. The check valve may exit the flange under extreme operating and mounting conditions. To avoid this phenomenon, it is mandatory to connect the softener with flexible hoses (according to diagram here below). We also recommend to install a leak detection system (e.g. BWT AQAStop). CAUTION : Do not insert a reduction or an adapter between the softener connection flange and the flexible hose. The flexible hose of the same diameter as the flange must have a gasket that keeps the check valve locked in its housing.

Open the salt lid (4), remove the cap (17), then the brine valve (5) from its well (16). Set the float height (X), rod pulled, at the value provided on your Scope of Delivery sheet. Check that the brining tube (9) is cut straight on its ends, put it on the sheath (15), then tighten it on the fitting located on the brine valve foot (18), using the fly nut (19). Put the brine valve (5) back into the bottom of the well (16), pass the brining tube (9) through the hole of the cap (17), then put this cap back upon the well (16). Pass the brining tube (9) through the dedicated hole in the salt tank, making sure that this tube does not bend anywhere. Connect the hydraulic block

Connect the brining tube (9) to the quick fitting (20). Connect the in and out flexible hoses (13) respectively on the flange fittings (21) and (22) of the hydraulic block. Connect the drain tube (8) on the splined fitting (23) and tighten it with a hose clamp (Serflex type). Connect the plug of the chlorination cell if your softener has this option (24). Connect drain outlets. @ Connect the drain tube (8) to the upper fitting of the siphon (11) and tigh- ten it with a hose clamp (Serflex type). The siphon ensures the mandatory protection of the domestic water circuit against sewage backflow. © Connect the tube of the salt tank overflow (10) to the side fitting of the siphon (11), respecting a slope of mini- mum 2% (2 cm per meter) from the tank overflow to the siphon. Then tighten it with a hose clamp (Serflex type). The overflow must take benefit of gravity and follow a simple and short way. f not possible, install a lift pump compatible with salted water. Connect the siphon (11) to the drain by a rigid PVC tube with a diameter of 40 mm, tightened on the fitting (25). Complete the connections and purge the air. tapping point if the filter is not equipped. Plug the softener to the electricity outlet. Before opening the water inlet into the installation, purge and rinse properly the pipes upstream from the bypass. Connect the inlet and outlet flexible hoses (13) to the network pipe, by paying attention to the water flow direction. Progressively open the bypass tap (or the upstream cutting valve of the installation). Purge the remaining air by using the purging screw upon the filter (unscrew it, then screw it back once the air is purged) or by a downstream Code P0011144GR - Rev 16 - 04/01/2022
