Application
Thermostat mixers are designed for hot water supply via
pressurised storage heaters and, utilised in this way, provide
the best temperature accuracy. With sufficient power output
(from 18 kW or 250 kcal/min), electric or gas instantaneous
heaters are also suitable.
Thermostats cannot be used in conjunction with
non-pressurised storage heaters (displacement water
heaters).
All thermostats are adjusted in the factory at a flow pressure
of 3 bar on both sides.
Should temperature deviations occur on account of special
installation conditions, the thermostat must be adapted to local
conditions (see Adjusting).
Specifications
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 supply
Recommended max. flow temperature (energy saving) 60 °C
Safety stop
Hot water temperature at supply connection min. 2 °C higher
than mixed water temperature
Cold water connection
Hot water connection
Minimum flow rate
If static pressure exceeds 5 bar, a pressure reducing valve
must be fitted.
Installation
Flush piping system prior and after installation of fitting
thoroughly (Consider EN 806)!
1. Install the S-unions and sleeve, preassembled with the
escutcheon, see fold-out page II, Fig. [1].
2. Screw-mount the mixer and check connections for leakage.
3. Push the sleeve with escutcheon onto the union nut.
4. Screw the escutcheon flush against the wall.
Refer to the dimensional drawing on fold-out page I.
The projection can be increased by 30mm with an extension,
see Replacement Parts, fold-out page I, Prod. no. 46 238.
Reversed connection (hot on right - cold on left).
Replace thermostatic compact cartridge (P), see Replacement
parts, fold-out page I, Prod. no.: 47 175 (1/2").
When using this thermostatic compact cartridge,
the Cool Touch function is no longer available.
Adjusting
Temperature adjustment, see Figs. [2] and [3].
1. Open the shut-off valve and check the temperature of the
water with a thermometer, see Fig. [2].
2. Lever out cap (A), see Fig. [3].
3. Remove screw (B).
4. Detach temperature control handle (C).
5. Turn regulating nut (D) until the water temperature has
reached 38 °C.
6. Install temperature control handle (C) so that button (E)
points towards the front, see Fig. [2].
7. Screw in screw (B), see Fig. [3].
8. Refit cap (A).
Temperature limitation
The safety stop limits the temperature range to 38 °C. The 38 °C
limit can be overridden by pressing the button (E), see Fig. [2].
Adjusting the economy stop
Volume adjustment, see fold-out page II, Figs. [4] and [5].
• The flow rate is limited by a stop adjusted at the factory. If a
higher flow rate is desired, the stop can be overridden by
pressing the button (F), see Fig. [4].
To adjust the stop, proceed as follows:
1. Close shut-off valve.
2. Lever out cap (G).
3. Remove screw (H) and detach shut-off handle (J).
4. Remove splined adapter (K) and economy stop (L).
5. Reinstall economy stop (L) in the desired position. For
0.5 bar
adjustment range, see Fig. [5].
6. Fit splined adapter (K), see Fig. [4].
1 bar
7. Fit shut-off handle (J) so that the button (F) points towards
10 bar
the front.
1 - 5 bar
8. Screw in screw (H).
16 bar
9. Refit cap (G).
approx. 26 l/min
80 °C
Prevention of frost damage
When the domestic water system is drained, thermostat
38 °C
mixers must be drained separately, since non-return valves
are installed in the hot and cold water connections. For this
purpose, the mixer must be removed from the wall.
right
Maintenance
left
= 5 l/min
Inspect and clean all parts, replace if necessary and lubricate
with special valve grease.
Shut off the hot and cold water supply.
I. Non-return valve (M), see fold-out page II, Fig. [6].
• Remove connection nipple (O) by turning clockwise (left-
hand thread) using a 12mm allen key.
Install in reverse order.
II. Thermostatic compact cartridge (P), see fold-out page II,
Fig. [7].
• Remove O-ring (R1).
• Loosen screw ring (R) using a 34mm tool.
• If necessary, lever out thermostatic compact cartridge (P)
via recess (P1).
• Remove screw ring (R).
Install in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (P) and scale ring (S), see
details Fig. [7].
Readjustment is necessary after every maintenance operation
on the thermostatic compact cartridge (see Adjusting).
III. Ceramic headpart (T), see fold-out page II, Fig. [8].
Install in reverse order.
Replacement Parts, see fold-out pages I ( * = special
accessories).
