mounting template. Seal any apertures in the wall so that
they are watertight to spray water.

tapered towards the outside.
• Seal prefabricated walls with a permanently plastic
compound.
Shut off cold and hot water supplies.

Adjustment
Installation of the temperature control handle (O) and
temperature adjustment, see fold-out page III figs. [5]
and [6].
• 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. [5].
2. Turn the adjusting nut (N) clockwise or anticlockwise until
the water temperature reaches 38 °C.
3. Install temperature control handle (O) so that the button (P)
is at top, see fig. [6].
4. Install in screw (Q).

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 pressing button (P), see fig. [6].
Temperature end stop
If the temperature end stop is at 43 °C, insert accompanying
temperature limiter (O1) in temperature control handle (O),
see fig. [7]. Handle with preassembled temperature end stop,
ref. no.: 47 920 (see Replacement parts, fold-out page II).
Prevention of frost damage
When the domestic water system is drained, thermostats 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

Inspect and clean all parts, replace if necessary and lubricate
with special grease.
Shut off hot and cold water supplies.
