3. Temperature readings should be taken at the normal flow
rate after allowing the system to stabilise. Any TMV that has
been adjusted or serviced must be re-commissioned and re-
tested in accordance with the manufactures‘ instruction.
Note:
1. If the TMV’s are supplied from storage cistern by gravity
then the supply pressure should be verified to ensure the
conditions of use are appropriate.
2. The maximum mixed water temperature can be 2°C above
the recommended maximum set mixed water temperature.
The mixed water temperature must never exceed 46°C. 46°C
is the maximum mixed water temperature from the bath tap
and takes account of allowable temperature tolerances in
thermostatic mixing valves and temperature losses in metal
baths. It is not a safe bathing temperature for adults or
children. 37°C is the maximum recommended temperature for
children/babies under 18 months, 40°C is the maximum
recommended temperature for adults/children over 18 months.
Installation
Refer to the dimensional drawing on page 1.
Flush pipes thoroughly before and after installation
(observe EN 806) !
Screw thermostat on hot water service valve, see page 3,
Fig. [1].
It is recommended that for installation and to secure the non-
return valve the connection set [ref. No. 47 533, see page 2] or
the hose [ref. No. 45 704] are used.
It is recommended that a flexible pressure hose is connected
as installation aid for fittings with copper pipes [ref. No. 45 120,
see page 2].
Connection to pillar tap, see page 4 Figs. [2a] and [3a].
Connection to mixer fitting, see page 4 Figs. [2b] and [3b].
Open the hot and cold water supply and check that
connections are watertight.
Adjustment
Before the mixer is put into service and after any maintenance
operation on the thermostatic compact cartridge the
thermostat must be adjusted.
For pillar taps the mixed water temperature is adjusted at the
thermostatic compact cartridge.
For mixer fittings the max. hot water temperature is adjusted
at the thermostatic compact cartridge.
Temperature setting, see page 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 thermostat must be removed from the unions.
Thermal disinfection
With the supplied key a thermal disinfection can be carried out
without changing the setted temperature. A subsequent
adjustment is not necessary.
Thermal disinfection, see page 5
- Start by turning the key to the left.
The flushing time during the thermal disinfection depends on
the water temperature. National standards must be
observed.
- Terminating by turning the key to the right until it stops.
Maintenance
Inspect and clean all components and replace if necessary.
Shut off cold and hot water supply.
I. Non-return valves, see page 5
II. Thermostatic compact cartridge, see page 5
- If necessary, lever out thermostatic compact cartridge via
recess (A), see detail.
Assemble in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge,
see detail (B).
Readjustment is necessary after each maintenance operation
on the thermostatic compact cartridge (see Adjustment).
Assemble in reverse order.
In order to ensure long-term protection from scalding, at
least once a year must be checked that the pre-adjusted
outlet temperature is not exceeded.
If the temperature has been exceeded, it must be readjusted
(see Adjustment).
Spare parts, see page 2 ( * = special accessories).
