4. Function

Infinitely variable setting of the mixed water tem-
perature between 30°C - 65°C is carried out at the
handwheel. Breakdowns and malfunctions are re-
liably avoided by a control piston made of high
quality plastic and a resistance of the thermostatic
mixing valve to calcification and corrosion is en-
sured.
The set temperature can be locked and lead
locked. In order to avoid self-acting or inadvertent
tampering, the handwheel has to be pushed
down and turned to set the mixed water tempera-
ture.
The inlet temperatures at the hot or
cold-water side have to be at least 10°C
above or below the process water tem-
perature set for the process water mixer
to work properly.
To prevent an automatic or unintentional adjust-
ment, the handwheel has an anti-rotation element.
Push down the handwheel and rotate to set the
combined waste water temperature. After setting
the combined waste water temperature check
whether the handwheel has engaged back into the
anti-rotation element.

Presetting can be secured by blocking the hand-
wheel which can then no longer be pushed down
or turned. With the handwheel engaged, turn the
green locking disc in the middle of the handwheel
clockwise with a coin or similar until the bore hole
of the locking disc faces the bore hole of the
handwheel.
To do this, when the handwheel has engaged, ro-
tate the green locking disc in the middle of the
handwheel clockwise with a coin or similar until
the hole in the locking disc is opposite the hole in
the handwheel.

If required, the setting of the thermostatic mixing
valve can now be lead sealed.

5. Installation

The thermostatic mixing valve must be installed in
the potable water system without tensions and
flectional strains. The valve must be easily acces-
sible to facilitate operation.
If the valve is installed in a circulation system, non-
return valves for cold water (item no. 130 20 06-10)
must be used to avoid volume flows against the
direction of flow.
To avoid malfunctions caused by impurities, the
installation of filters (item no. 112 00 06-10) n the
supply pipes of the mixing valve is recommended.
Control of the mixed water temperature is carried
out with the help of the inline thermometer (item
no. 130 09 52-54), which can directly be connected
to the connections of the thermostatic mixing valve.
