To replace the valve:
24. Loosen grub screw (A5) on the rear of spout (A4) using a 2.5mm A/F allen key.
25. Pull the spout (A4) vertically away from the control block (B3).
26. Remove PTFE ring (B1).
27. Loosen grub screw (B2) on the rear of control block (B3) using a 2.5mm A/F allen key.
28. Pull the control block (B3) and PTFE ring (B5) vertically away from the body (D2).
29. Loosen grub screw (D1) on the rear of body (D2) using a 2.5mm A/F allen key.
30. Unscrew the valve shroud (A10) using an adjustable spanner on the opposite flats.
31. Remove gaskets (C1&C2), small o-ring (C3), splined collar (C4) & large o-ring (C5).
32. Remove locking nut (C6) using Circlip or long nose pliers. Pull the old valve cartridge (C7) away from the body (D2).
33. Ensure that the inside of body (D2) is clean of dirt and grit.
34. Place the new valve (C7) in the body (D2), ensuring the locators on the base of valve (C7) align with the recesses in the chamber of
the tap (D2).
35. Replace the fixing nut (C6) and tighten until the valve (C7) is secure.
36. Replace the o-ring (C5) over the fixing nut (C6).
37. Turn the splined valve stem of the valve (C7) fully clockwise (i.e. the off position)
38. Place the splined collar (C4) over the valve stem of the valve (C7) so that the threaded hole directly faces the rear centre of the tap body (D2).
39. Push gasket (C1) up inside the chamber of the valve shroud (A10) so that it seats flat.
40. Pass (C3) then (C2) over the valve stem of the valve cartridge (C6). Note the orientation of (C2).
41. Screw the valve shroud (A10) into the body (D2). Note the orientation of the slot in valve shroud (A10) must match the threaded hole in the
rotating splined collar (C4). When the valve is turned fully clockwise grub screw (B2) must not foul on the end of the slot in the valve shroud
(A10), adjust the rotation of the valve shroud (A10) so the valve turns through 90° and fully to the off position with grub screw (B2) inserted.
42. Re-tighten grub screw (D1) to lock the valve shroud (A10) in place.
43. Replace PTFE ring (B5) centrally over the top of the valve shroud (A10), followed by the control block (B3)
44. Tighten grub screw, (B2) of the control block (B3) into the threaded hole in the splined collar (C4) using a 2.5mm A/F allen key.
45. Replace PTFE ring (B1).
46. Replace spout (A4), fixing it in position by tightening grub screw (A5) on the rear of spout (A4) using a 2.5mm A/F allen key.
To replace the spout o-rings:
8.
Loosen grub screw (A5) on the rear of spout (A4) using a 2.5mm A/F allen key.
9.
Pull the spout (A4) vertically away from the control block (B3).
10. Remove the old o-rings (A7 & A8) using a small screwdriver or similar.
11. Ensure the inside of the spout (A4) and the top of the valve shroud (A10) is clean of dirt and grit with a soft wet cloth.
12. Carefully locate the new O-rings (A7 & A8) onto the top of retaining nut (B7).
13. Grease the O-rings (A7 & A8) thoroughly with silicone or alternative similar grease.
14. Reassemble the tap in the reverse order ensuring PTFE ring (B1) is placed into the recess on control block (B3).
To replace the valve shroud gaskets:
1.
Loosen grub screw (A5) on the rear of spout (A4) using a 2.5mm A/F allen key.
2.
Pull the spout (A4) vertically away from the control block (B3).
3.
Remove PTFE ring (B1).
4.
Loosen grub screw (B2) on the rear of control block (B3) using a 2.5mm A/F allen key.
5.
Pull the control block (B3) and PTFE ring (B5) vertically away from the body (D2).
6.
Loosen grub screw (D1) on the rear of body (D2) using a 2.5mm A/F allen key.
7.
Unscrew the valve shroud (A10) using an adjustable spanner on the opposite flats.
8.
Remove gaskets (C1&C2) and small o-ring (C3).
9.
Push new gasket (C1) up inside the chamber of the valve shroud (A10) so that it seats flat. (Note gasket orientation)
10. Pass (C3) then (C2) over the valve stem of the valve cartridge (C6). Note the orientation of (C2).
11. Now check that locking nut (C6) is tight.
12. Screw the valve shroud (A10) into the body (D2). Note the orientation of the slot in valve shroud (A10) must match the threaded hole in the
rotating splined collar (C4). When the valve is turned fully clockwise grub screw (B2) must not foul on the end of the slot in the valve shroud
(A10), adjust the rotation of the valve shroud (A10) so the valve turns through 90° and fully to the off position with grub screw (B2) inserted.
