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.
A shutoff device (A) must be installed after the mixed water outlet of
concealed thermostatic mixer (34 101), see Fig. [1].
For an order number index to the various installation components
for the concealed mixer, see Fig. [2].
a = Size of union
b = Part
c = Part No.
When this model is used as a central thermostat, standard mixers
can be installed at the draw-off points, in this case, the thermostat
mixer supplies hot water to which cold water can be added.
The built-in thermostat with stop-valve (34 100) only shuts off the
upper outlet. An additional stop valve must be fitted if the lower
outlet is used, see Fig. [2].

Minimum flow rate
At a flow pressure over 5 bar it is recommended that a pressure
reducing valve be fitted in the supply line.
Prevention of frost damage
When the domestic water system is drained, the thermostat mixers
must be drained separately, since non-return valves are installed in
the hot and cold water connections. The complete thermostat
assembly and non-return valves must be unscrewed and removed.

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 Fig. [3].
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. [4] (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. [5]. The housing is provided with pre-drilled
holes (B) to facilitate mounting the fitting to the wall, see Fig. [4].
- 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 posi-
tion.
Test the pipelines and concealed thermostat module
connections for leaks.
Flush pipelines thoroughly.

4. Install flushing plugs (F) in non-return valve seat recesses, see
10 bar
Fig. [7].
1 - 5 bar
5. Open the hot and cold water supplies and flush pipes thoroughly.

6. Close the hot and cold water supplies, remove flushing plugs (F)
and reinstall non-return valves (E).
