6.4  How to access the mechanism assembly

To gain access to the mechanism assembly (

13

) the cover (

2

)  needs  to  be  removed.  For        

this, and any servicing, the trap may remain in the pipeline.

Ensure the trap is depressurised (see 'Section 6.1 - General information')

Unscrew the 14 off cover nuts (

5

) and remove the cover (

2

) and cover gasket (

3

).  The                     

cover (

2

) weighs in the region of 35 kg (77 lb) and threaded connections are provided (one 

at each end) for the use of M12 lifting eyes. Place the cover (

2

) down in such a manner 

as not to damage the gasket face.

The mechanism assembly (

13

) will now be clearly visible. It is retained to the body by          

2 off M12 assembly studs and nuts (

18a

 and 

18b

), Figure 7. These are located at the 

opposite end to the float (

14

). Unscrew the 2 assembly nuts (

18b

) and remove the 

mechanism assembly (

13

) and assembly gasket (

19

).
