Installation
- 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].
- Fit sleeve (C), see fig. [2].
- Grease the seal (D) for the escutcheon mounting
bracket (E) with the special grease supplied and
install escutcheon mounting bracket (E) with
screws (F), see fig. [3].
- Fit the escutcheon (G).
If the thermostat has been installed at too great a
depth, this can be adjusted by 27.5mm with an
extension set (see fold-out page II, ref. No. 47 653).
Adjustment
Installation of the thermostat knob and
temperature adjustment, see figs. [4] and [5].
• 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. [4].
2. Turn the adjusting nut (Q) clockwise or anticlockwise
until the water temperature reaches 38 °C.
3. Install temperature control handle (H) in such a way
that the 38° mark is at top, see fig. [5].
4. Fit snap insert (J) and install with screw (K).
5. Fit knob (L).
Reversed union (hot on right - cold on left).
Replace thermoelement (M) or (N), see replacement
parts fold-out page II, ref. No.: 47 657 (1/2")
and 47 658 (3/4").

Temperature limitation

The safety stop limits the temperature range to 38 °C.
If a higher temperature is desired, the 38 °C limit can
be overridden by depressing the button (H1).
Prevention of frost damage
When the domestic water system is drained,
thermostat mixers must be drained separately, since
non-return valves are installed in the hot and cold
water connections.
The complete thermostat assemblies and non-return
valves must be unscrewed and removed.

Maintenance

For maintenance, see fold-out page II and fig. [6].
Inspect and clean all parts, replace if necessary and
grease with special valve grease.
