Installation Requirements
This shower mixer valve must be installed in com-
pliance with current Water Regulations. If you have
any doubts about the Water Regulation requirements
contact your local water services provider or use the
services of a professional plumber.
This mixer valve is suitable for use with the following
water supply systems:
Gravity Fed Hot and Cold (pressure balanced) 0.1 - 1.0 bar
Gas Combination Boiler (multi-point) 1.0 - 10 bar*
Unvented System (pressure balanced) 1.0 - 10 bar
Pumped System 1.0 - 10 bar
IMPORTANT: If you install this mixer with a
gravity fed system, there must be a minimum head
(vertical distance) from the underside of tlie cold
water storage tank to the showerhead position of
at least 1 metre.
Before connecting the mixer, water should be flushed
through the system to remove all debris that might
otherwise damage the valve.
* If pressure is in excess of 3.5 bar, a pressure-
reducing valve should be fitted.

1. The hot and cold water outlets should be 150mm
apart (plus or minus 12mm). Hot on the left and
cold on the right (fig. 1). The recommended
plumbing fittings are ½“ back plate elbows (not
supplied).
2. Flush through the hot and cold water supplies.
3. Wrap PTFE tape round the S-unions and screw
into the backplate elbows. The S-unions must
protrude beyond the tiled surface between 32
and 41mm (figs.2-3).
4. Seal the gap between the S-unions and the tiles
(fig.3).
5. Screw the escutcheons onto the S-unions.
6. Fasten the mixer onto the S-unions using the
union nuts. Align the unit and tighten the nuts
(be careful not to damage the chrome finish). The
S-unions allow inaccuracies to be compensated
for.
