Safety notes
Caution: Risk of scalding
Before and during use make sure that the thermostat
is functioning correctly. Children and adults with
reduced sensory capabilities should not use the product
unsupervised.
Safety and important information
This thermostatic valve will suit supplies of:
High pressure.

NOTE: Valves operating outside these conditions cannot be
guaranteed by the Scheme to operate as Type 2 valves.
The designation of use is high pressure tub (HP-T) and high
pressure shower (HP-S).
HP-S for 34 562
HP-S and HP-T for 34 569
If a water supply is fed by gravity then the supply pressure
should be verified to ensure the conditions of use are
appropriate for the valve.
Recommended outlet temperature
• 44 °C for bath fill
but:
- 41 °C for shower and washbasin
- 38 °C for bidet
The mixed water temperatures must never exceed 46°C.
The maximum mixed water temperature can be 2°C above the
recommended maximum set outlet temperatures.
NOTE: 46°C is the maximum mixed water temperature from
the bath tap. The maximum temperature takes account of the
allowable temperature tolerances inherent in thermostatic
mixing valves and temperature losses in metal baths.
It is not a safe bathing temperature for adults or children.
The British Burns Association recommends 37 to 37.5 °C as a
comfortable bathing temperature for children. In premises
covered by the Care Standards Act 2000, the maximum mixed
water outlet temperature is 43 °C.
The thermostatic mixing valve will be installed in such a
position that maintenance of the TMV and its valves and the
commissioning and testing of the TMV can be undertaken.
Requirements shall be verified against the original set
temperature results once a year.
The installation of thermostatic mixing valves must comply with
the requirements of the Water Supply (Water Fittings)
Regulations 1999.
The fitting of isolation valves is required as close as is
practicable to the water supply inlets of the thermostatic mixing
valve.

Notes
If there is a residual flow during the commissioning or the
annual verification (cold water supply isolation test), then this
is acceptable providing the temperature of the water seeping
from the valve is no more than 2°C above the designated
maximum mixed water outlet temperature setting of the valve.
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).

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)!
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 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").
Adjusting
Temperature adjustment, see fold-out page I Fig. [2].
Temperature limitation
The safety stop limits the temperature range to 38 °C.
The 38 °C limit can be overridden by pressing the button, see
Fig. [3]. Temperatur end position is at 46 °C.
If 43 °C temperatur end position is desired please take the
temperatur limiter (in the scope of delivery) shown in Fig. [3].
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].
Shut-off handle and diverter operation, see fold-out
page III, Fig. [5].
Prevention of frost damage
When the domestic water system is drained, thermostat
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.
