Application
Thermostat mixers are designed for hot water supplies from
pressurised storage heaters and offer the highest temperature
accuracy when used in this way. Given sufficient output
(min. 18 kW or 250 kcal per min), electric or gas-fired
instantaneous heaters are also suitable.
Thermostat mixers cannot be used in conjunction with low-
pressure storage heaters (displacement heaters).
All thermostat mixers are adjusted at the factory at a flow
pressure of 3 bar on both sides.
The built-in thermostat only shuts off the upper outlet. An
additional stop valve must be fitted if the lower outlet is used.
For an order number index to the various installation
components for the concealed mixer, see fold out page II
fig. [1].
a = Size of union
b = Part
c = Part No.
Technical Data
Minimum flow pressure without downstream
resistances 0.5 bar
Minimum flow pressure with downstream
resistances 1 bar
Max. operating pressure 10 bar
Recommended flow pressure 1 - 5 bar
Test pressure 16 bar
Flow rate at 3 bar flow pressure approx. 24 l/min
Max. water temperature at hot water inlet 80 °C
Recommended max. flow temperature 60 °C
(for energy saving)
Safety stop 38 °C
Hot water temperature at supply connection min. 2 °C higher
than mixed water temperature.
Hot water connection - W - (-H-) left
Cold water connection - K - (-C-) right
Minimum flow rate 5 l/min
At a flow pressure over 5 bar it is recommended that a
pressure reducing valve be fitted in the supply line.
New installations
- Prepare wall ready for mixer.
Drill holes for thermostat mixer and chase-out grooves for
pipelines.
- Observe the installation depth in accordance with the
instructions given on the mounting template, see also fold
out page II fig. [2].
x = Face of tiles
y = Front face of mounting template
z = Resting point for spirit level
- Align the mixer horizontally, vertically and parallel to the wall,
see fig. [3] (place a spirit level on the cams or face of the
mounting template).
- Install concealed thermostat mixer module in wall and
connect pipelines, see fig. [4].
The housing is provided with pre-drilled holes (B) to facilitate
mounting the fitting to the wall, see fig. [3].
-Do not solder the connections between the pipelines
and housing, otherwise the built-in non-return valves may
be damaged.
- Seal the open outlet with screw plug.
Note!
-The hot water supply must be connected on the left
(marked W (H) on housing) and the cold water supply on
the right (marked K (C) on housing), as viewed from the
operating position.
Open cold and hot water supplies.
Test the pipelines and concealed thermostat module
connections for leaks.
Flush pipelines thoroughly.
1. Remove screws (C) and mounting template (D), see
fig. [5].
2. Close the hot and cold water supplies.
3. Remove screw plug (E).
4. Remove non-return valve (F) and filter (G).
5. Install flushing plugs (H) in non-return valve seat recesses,
see fig. [6].
6. Open the hot and cold water supplies and flush pipes
thoroughly.
7. Close the hot and cold water supplies and remove flushing
plugs (H).
8. Install filter (G) and non-return valve (F), see fig. [5].
9. Install screw plug (E).
10. Reinstall mounting template (D).
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.
Do not remove the fitting template before final installation.

Final installation
1.Remove screws (C) and mounting template (D), see fig. [7].
2.Install holder (J) and fit sleeve (K) and (L), see fig. [8].
3.Grease the seals (M1) for the escutcheon mounting
bracket (M2) with the special grease supplied and install
escutcheon mounting bracket (M2) with srews (N), see
fig. [9].
4.Fit the escutcheon (M).
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 I, ref. No. 47 200).
Open cold and hot water supplies.
Installation of the flow control knob (S) and adjustment of
the economy stop, see fold-out page II, figs. [10] to [12].
• The flow rate is limited by the economy stop (O) supplied,
see fig. [10].
To install the flow control knob (S), proceed as follows:
1.Close the ceramic headpart (P) by turning clockwise.
2.Install the economy stop (O) in the desired position.
For possible settings, see fig. [11].
3.Fit splined adapter (Q), see fig. [12].
4.Fit fastening set (R).
5.Install flow control knob (S) so that the button (S1) is at top.
If a higher rate is desired, the stop can be overridden by
depressing the button (S1).
Reversed connection (hot on right - cold on left). Replace
thermostatic compact cartridge (T), see Replacement Parts,
fold-out page I,Prod. no. 47 175 (1/2”).
Adjustment
Installation of the temperature control handle (U) and
temperature adjustment, see fold-out page III, figs. [13]
and [14].
• 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. [13].
2.Turn the adjusting nut (V) clockwise or anticlockwise until
the water temperature reaches 38 °C.
3.Fit fastening set (W), see fig. [14].
4.Install temperature control handle (U) so that the button (U1)
is at top.
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 (U1), see fig. [14].
Temperature limit stop
If the temperature limit stop should be 43 °C, use handel ref.
No. 47 812 (see fold-out page I).
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
Inspect and clean all parts, replace if necessary and grease
with special valve grease.
Shut off cold and hot water supplies.
I. Thermostatic compact cartridge (T), see fold-out page III,
fig. [15] to [17].
• Loosen screw ring (X) using a 34mm tool.
• If necessary, lever out thermostatic compact cartridge (T) via
recess (T1).
• Remove screw ring (X).
Assemble in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (T), see detail (T2).
Readjustment is necessary after every maintenance operation
on the thermostatic compact cartridge (see Adjusting).
II. Non-return valve (F) or (F1), see fold-out page III
figs. [15], [16], [18] and [19].
Assemble in reverse order.
III. Ceramic headpart (P), see fold-out page III figs. [15], [16]
and [18].
Assemble in reverse order.
Observe the correct mounting positions!
