Application
Thermostat mixers are designed for use with hot water
supplied from pressurized 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 water heaters).
All thermostat mixers are adjusted at the factory at a flow
pressure of 45 psi on both sides.
If temperature deviations should exist due to special
installation conditions, then the thermostat is to be adjusted to
the local conditions (see Adjustment).

At a flow pressure over 72.5 psi it is recommended that a
pressure reducing valve be fitted in the supply line.
Installation
Flush piping system prior and after installation of faucet
thoroughly!
Install S-unions and screw-mount the mixer, see fold-out page I,
Fig. [1].
Refer to the dimensional drawing on fold-out page I.
The projection can be increased by 3/4" (20mm) with an
extension, see Replacement Parts, fold-out page II, Prod.
no. 07 130.
Reversed connection (hot on right - cold on left).
Replace thermostatic compact cartridge (U), see Replacement
parts, fold-out page II, Prod. no.: 47 175 (1/2").
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 100 °F.
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 100 °F.
The 100 °F limit can be overridden by pressing the button (E).
Adjusting the economy stop
Volume adjustment, see fold-out page I, 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
adjustment range, see Fig. [5].
7.25 psi
6. Fit splined adapter (K), see Fig. [4].
7. Fit shut-off handle (J) so that the button (F) points towards
14.5 psi
the front.
145 psi
8. Screw in screw (H).
14.5 psi - 72.5 psi
9. Refit cap (G).
232 psi
Check operation of automatic diverter (M), see fold-out
page III, Figs. [6].
Flow is diverted automatically from shower outlet to bath inlet
176 °F
when the fitting is closed.
Prevention of frost damage
70 - 115 °F
When the domestic water system is drained, thermostat
100 °F
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.

Maintenance
1.3 gpm
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 (R) or (S), see fold-out page III, Fig. [7].
• Remove connection nipple (P) by turning clockwise (left-hand
thread) using a 12mm allen wrench.
Install in reverse order.
II. Thermostatic compact cartridge (U), see fold-out page III,
Fig. [8].
• Loosen screw ring (T) using a 34mm tool.
• If necessary, lever out thermostatic compact cartridge (U)
via recess (U1).
• Remove screw ring (T).
Install in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (U), see detail (U2).
Readjustment is necessary after every maintenance operation
on the thermostatic compact cartridge (see Adjusting).
III. Ceramic headpart (V), see fold-out page III, Fig. [9].
Install in reverse order.
IV. Unscrew and clean mousseur (13 952) see fold-out
page II.
Replacement Parts, see fold-out pages II ( * = special
accessories).
