Application
Thermostat mixers are designed for hot water supplies from
pressurised storage heaters and offer the highest temperature
accuracy when used in this way.
Thermostat mixers cannot be used in conjunction with low-pressure
storage heaters.
All thermostat mixers are adjusted at the factory with a flow
pressure of 3 bar on both sides.
An additional stopvalve is only required if draw-off points are
connected to the lower outlet.
Technical Data
Minimum flow pressure without downstream resistances
Minimum flow pressure with downstream resistances
Max. operating pressure
Recommended flow pressure
Test pressure
Flow rate at 3 bar flow pressure
Max. water temperature at hot water inlet
Recommended max. flow temperature (for energy saving)
Safety stop
Hot water temperature at supply connection min. 2 °C higher than
mixed water temperature.
Hot water connection - W - (- H -)
Cold water connection - K - (- C -)
Minimum flow rate
At a flow pressures above 5 bar, we recommend installing a
pressure reducer in the supply pipe.
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 installation
- 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. [1].
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. [2] (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. [3]. The housing is provided with pre-drilled
holes (A) to facilitate mounting the fitting to the wall, see Fig. [2].
- Do not solder the connections between the pipelines and
housing, otherwise the built-in non-return valves may be
damaged.
- Seal the bottom 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.
Caution!
The upper outlets are sealed by the factory.
Checking pipes and thermostatic mixer body for leaks.
1. Remove screws (B) and fitting template (C),
see Fig. [5].
2. Install special socket spanner supplied (D) on shut-off
spindle (E), see Fig. [4].
3. Turn spanner (D) clockwise and pressure test the bath outlet.
4. Turn spanner (D) anticlockwise and pressure test the shower
outlet.
5. Return spanner (D) to starting position (fitting closed) and
remove.
6. Reinstall fitting template (C).
