Using the same template as for the pipe centres, mark the three fixing holes for the back plate. Remove the backplate from the shower unit and fix it to the wall using a drill with a masonry bit. Three x no. 8 x 1¼” screws and wall plugs are supplied. Seal the concealing plates with silicon and press them to the wall.
It is essential at this point that the supply pipework is thoroughly flushed through before connection to the mixer. Failure to do so may result in product malfunction and will not be covered under the guarantee.
