Safety notes
Protection against scalding
It is recommended that near points of discharge with
particular sensitivity to the outlet temperature
(hospitals, schools, nursing and retirement homes)
thermostatic devices should be installed which can limit the
water temperature to 43 °C. The product includes an
appropriate temperature end stop. It is generally
recommended that the temperature of shower-systems should
not exceed 38 °C in nurseries and specific areas of care
centres. Use Grohtherm Special thermostats with special
handle to facilitate thermal disinfection and appropriate safety
end stop. Applicable standards (e. g. EN 806-2) and technical
regulations for drinking water must be observed.
Safety and important information
This thermostatic valve will suit supplies of:
High pressure.
Conditions of use TMV2

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 34 438, 34 557, 34 818 and 34 825
HP-S and HP-T for 34 439 and 34 821
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).
