Manual shower valve mystery parts

[freddyuk]

Anyone help me please?

I bought a manual shower valve suitable for high and low pressure(including combi)

In the box i appear to have the wrong instructions as they are for a different diverter valve with a different template.

Also in the box are two ;what look like pressure reducers, one has a blue arrow the other has a grub screw like a service valve except it has plastic fitting inside like a check valve.

Do i fit these if i i have mains fed system and what goes where? or are they for a different unit and i dont need them?

I am also using a pressure equalising valve as this unit does not do that job.

Any thoughts?

Many thanks

Why don't you take it back and get the right instructions & template.

Mail order - and they are working on getting me the correct instructions.

I really dont have time to wait for them to pull their finger out.I think i am right that these are pressure reducers and i dont need them.
