using Rear Mountings

1.

  Determine the route for the hot and cold supply 

pipework and for the outlet pipework. When 

connecting to the BIV Shower Fittings it is 

recommended that the outlet be positioned 

above and to one side of the mixer. This is to 

prevent the flexible hose from obstructing the 

shower controls.

2.

  Remove the two shroud screws then remove 

the building-in shroud from the mixer. 

Note!

 Refit the shroud screws to the mixer.

3.

  Determine the position of the mixer and draw 

around the building-in shroud.

4.

  Mark the routes for the supply pipework at 

108 mm centres (

Hot - Left, Cold - Right

).

Falling Supplies:

 For falling supplies loosen 

the grubscrew on each elbow using the 2.5 mm 

hexagon key (supplied). Remove the elbows 

and install on opposite sides. Retighten the 

grubscrews.

Caution! 

Do not overtighten.

Note!

 Make sure that the ‘O’ seals are correctly 

fitted and that the filter caps can be accessed 

from the front (i.e. hexagonal key facing 

forward).

5.

  Cut away the plasterboard and/or brick work 

to the required depth.

Important!

 This depth ‘X’ will depend on the 

finished wall thickness e.g. tiles or facia board. 

Refer to the table for this measurement. 

  For stud partitions depth ‘X’ refers to the 

distance from the rear mounting e.g. timber 

noggin, to the front of the wall (before tiling).
