• Before the mixer is put into service, if the mixed water
temperature measured at the point of discharge varies from
the specified temperature set on the thermostat.
• After any maintenance operation on the thermostatic
cartridge.
1. Open the shut-off valve and check the temperature of the
water with a thermometer, see Fig. [8].
2. Turn the regulating nut (Q) clockwise or anticlockwise until
the water temperature reaches 38 °C.
3. Install mounting set (S), see Fig. [9].
4. Install temperature control handle (R) so that the button (V)

be drained separately, since non-return valves are installed in
the hot and cold water connections.
The complete thermostat assemblies and non-return valves
must be unscrewed and removed.
Maintenance
Inspect and clean all parts, replace as necessary and lubricate
with special grease.
Shut off cold and hot water supplies.
