• After installation, deposit this leaflet with the owner of the valve for future references.

Temperature Adjustment

To set the mixed water temperature, follow the steps described in Fig. E1-E2. The temperature should be checked annually to ensure that the setting of the valve is correct.

Service and Maintenance

Under normal conditions maintenance will not be required. If necessary, the gasket (O-rings), sensing element, and valve plug are easily replaced. See fig. A for replacement part details. Before dismantling the valve, shut off the water supply. If the valve is fitted below the calorifier, drain it first. Hard water conditions may result in scale deposits causing sticking of internal parts in extreme cases. Cleaning the internal parts will usually restore the valve to proper operating conditions. It may be necessary to clean the seat and/or exchange the thermostat. To clean and/or restore the valve, shut off the water and:

1. Remove carefully all scaling (calcium deposits) or foreign particles from all internal parts.
2. When necessary, remove and clean the seat assembly in the same way.
3. Assemble the valve using only silicone grease.
4. Adjust the temperature (Fig. E1-E2).

The application examples inside this instruction manual are overall idea sketches. Always also take locally laws and regulations into consideration.
