ons.

on a bath 180mm apart with hot on the left and
cold on the right (fig.4).
2. Flush through the hot and cold water supplies.

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.

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.
