Maintenance

In service tests should be conducted regularly to monitor and record the performance of the valve. 
Deterioration in performance can indicate the need for servicing of the valve and/or water supply. 
If, during these tests, the mixed water temperature has changed significantly from the previous 
test results, record the change before re-adjusting the mixed water temperature. If the final mixed 
water temperature is greater than the permitted values, Verify details quoted in the Installation and 
Commissioning sections of this manual and that service work is required.

The following actions are recommended at least every 12 months, or more frequently if the need 
arises, and that the following steps are checked to maintain optimum valve performance.

Use the folllowing recommended procedure:
1) On the Caleffi SinkMixer valves, the inlet strainers on both the hot and cold water 
  inlet ports can be removed for cleaning by unscrewing the inlet union nut on the cold port and,
  with a screw driver, pop strainer out of the hot port.
2) If service is required, cleaning and de-scale as needed, or replace these check valves, see page
  6 for code numbers.

Once the above servicing is performed follow the commissioning details in the previous section 
ensuring that a suitably accurate thermometer is used.

Should the valve still not function correctly, it may be necessary to replace the valve entirely. 
Contact Caleffi Technical Support for details and advice.
