2. IInsertthecartridgeo󰀨setby20°,asshown:
Figure 6. - Fitting a cartridge
3. Rotatethecartridge20°CCWsothatit‘snaps’intoposition.
4. Push the cartridge lever down to secure the cartridge.

end. In the following order, place on to the tube:
1. Port sealing nut
2. Clamp ring
(observe correct orientation)
3. Tubetting
4. O-ring
NOTE: Max internal diameter of
connecting tubes: 6.3mm.
