Select Valve with Riser Rail

& Overhead (Square Style)

Atmos Select Square

IMPORTANT

This valve is factory preset so that the control knobs are fitted in the correct location. Do not turn

the shafts until you have fitted the handles after completing installation.

These fitting instructions assume you would wish to have the valve in a configuration such that

the temperature control is at the bottom and the diverter is at the top. You can fit it in any other

configuration you choose but you must make the appropriate amendments to the instructions

yourself. Ensure when changing the configuration of the valve the hot and cold inlets are correctly

connected as stated on the valve.

SITING OF THE SHOWER

Having established the position of the mixer valve so that all controls can be comfortably reached

whilst using the shower, the handset and riser rail should be positioned at the side of the valve

and the overhead rail directly above the valve. Make sure any cables and pipework are not behind

the required screw holes.

Consult the illustration below to make sure you check from the component list that all the parts

for your system are supplied.
