Installation to finished stage
- Plaster and tile the wall, excluding the area occupied by the
mounting template. Seal any apertures in the wall so that they
are watertight to spray water.
• Tiles laid in mortar should be pointed so that the joint is
tapered towards the outside.
• Seal prefabricated walls with a permanently plastic compound.
- Remove the mounting template, see fold-out page I fig. [1].
- Install holder (U), screw-mount sleeve (H) and sleeve (R), see
fig. [1].
- Grease the seals (T) of the escutcheon (K) with the special
grease supplied and install escutcheon (K) with screws (L), see
fig. [2].
- Fit the cap (O), see fig. [2].
If the thermostat has been installed at too great a depth, this
can be adjusted by 1 1/8" (27.5mm) with an extension set (see
fold-out page II and III, ref. No. 47 358).
Installation of the flow control knob and adjustment of the
economy stop, see figs. [3] to [5].
• The flow rate is limited by the economy stop (N) supplied, see
fig. [3].
To install the flow control knob, proceed as follows:
1. Close the ceramic headpart by turning clockwise.
2. Install the economy stop (N) in the desired position, see fig. [3].
For possible settings, see fig. [4].
3. Reinstall splined adapter (J) and shut-off knob (I) with economy

adjustment, see figs. [6] and [7].
• Before the mixer is put into service if the mixed water
temperature measured at the point of discharge varies from the
specified temperature set on the thermostat.
• After any maintenance operation on the thermoelement.
1. Open the shutt-off valve and check the temperature of the water
with a thermometer, see fig. [6].
2. Turn the adjusting nut (A) clockwise or anticlockwise until the
water temperature reaches 100 °F, see fig. [6].
3. Reinstall the thermostat knob (C) in such a way that the 100 °F
mark on the knob coincides with the mark (S) on the cap (O).
4. Reinstall screw (D) and refit cap (M), see fig. [7].
