             Follow these instructions for the correct way to install the supply tubes for hot and cold water: 
            
                - Screw the tubes onto the body using 11 mm. key (for copper tubes use a 13 mm. key), which should be positioned on the specific millings, avoiding closing them too tight (drawing A)
 
                - Screw the nuts G.3/8" to the connections of the hydraulic plant, using a 19 mm. key.
 
             
            IMPORTANT:  Do not use hexagonal keys or regulable pincers on the flexible nuts, which may compromise the durability of the flexible hoses (see drawing B)
