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).

Max. operating pressure
Recommended flow pressure
Test pressure
Flow rate: approx. 14 L/min or 3.7 gpm/20 psi
approx. 21 L/min or 5.5 gpm/45 psi
approx. 31 L/min or 8.2 gpm/100 psi
Max. water temperature at hot water inlet

the scale marked handle
safety stop
Hot water temperature at supply connection 4 °F higher than
mixed water temperature.
Cold water connection
Hot water connection
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 fitting
thoroughly!
Install 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.
Open cold and hot-water supply and check connections
for water-tightness.
Reversed connection (hot on right - cold on left).
Replace thermostatic compact cartridge, see Replacement
parts, fold-out page II, Prod. no.: 47 175 (1/2").
When using this thermostatic compact cartridge, the Cool
Touch function is no longer available.

Adjusting
Temperature adjustment, see fold-out page I Fig. [2].
Temperature limitation
The safety stop limits the temperature range to 100 °F.
The 100 °F limit can be overridden by pressing the button, see
Fig. [3].
Shower mixer:
Adjusting the economy stop, see fold-out page III Fig. [4].
If a higher flow rate is desired, the stop can be overridden by
pressing the button, fold-out page III Fig. [5].
Bath mixer:
Handle operation, see fold-out page III Fig. [6].
Eco function, by pressing the button the flow rate for the
7.25 psi shower can be increased.
14.5 psi
Prevention of frost damage
145 psi
When the domestic water system is drained, thermostat
14.5 psi - 72.5 psi
mixers must be drained separately, since non-return valves
232 psi are installed in the hot and cold water connections. For this
purpose, the mixer must be removed from the wall.
Maintenance
158 °F
Inspect and clean all parts, replace if necessary and lubricate
with special valve grease.
70 - 115 °F
Shut off the hot and cold water supply.
100 °F
Non-return valve, see fold-out page III, Fig. [7].
Remove connection nipple using a 12mm allen key.
Install in reverse order.
