GB- DSASSEMBLY AND ASSEMBLY 1 Disassembly To replace the spring (), or clean any of the internal components of the valve, proceed in the following manner: A Withdraw the clip (21), using a punching tool, and lift the lever (3). B Unscrew the cap () and remove. C Holding the rod (7) (2) steady, loosen the hollow screw nut (6), until the constructive limit, and the hollow screw (5) until you note a releasing of the spring (). D Unscrew the bell (2) holding the rod (7) (2) and the body (1) () steady. E Lift the bell (2) and you will have access to all the components. 2 Assembly A Enter the bell (2) and the joint (22) through the upper part of the rod (7) (2). B Turn the bell (2) holding the rod (7) (2) and the body (1) () steady. C Replace the hollow screw (5) with the hollow screw nut (6). D Adjust the set pressure with the hollow screw (5) and fix the adjustment position with the hollow screw nut (6). E Change the washer (23) and lightly tighten the cap (). F Place the lever (3) and fix it with the clip (21). ADJUSTNG THE SET PRSURE A Proceed according to DSASSEMBLY A, B, C. B Proceed according to ASSEMBLY D, E, F. ADJUSTEMENT OF THE BLOWDOWN A Slack the stud (12). B Twist or untwist the deflector (11) according the difference in the wished locking pressure (blowdown).
