Adjustment of thermostatic mixers

cartridge.
- Open the stopcock by means of the shut-off
knob (M) and check the temperature of the water
with a thermometer, see fig. [7].

Temperature limitation
The safety stop limits the temperature range to 38 °C.
If a higher temperature is desired, the 38 °C limit can
be overridden by pressing the button (V1).
Frost caution
When the domestic water system is drained,
thermostatic mixers must be drained separately
because there are non-return valves at the cold and
hot water connections.
In the case of thermostatic mixers, the complete
thermostat assemblies and non-return valves must be
removed.
Grout the joint around the top plate with a perma-
nently elastic material.
In this way, the inspection chamber will be accessible
at any time.
