Commissioning
6 Ensure that the application, in which the basin tap will be used, is appropriate for the
approved designation. The above information must be recorded and updated on every
occasion when any work is carried out on the basin tap.
Maintenance
To ensure the Sola thermostatic basin tap maintains a high level of protection, we advise the
following in service testing is conducted (the same equipment used to commission the basin tap
initially must be used in the following tasks).
1 After a period of between 6 and 8 weeks from commissioning carry out the following;
1.1 Record the temperature of the hot and cold water supplies.
1.2 Record the temperature of the mixed water from the basin tap.
2 If the mixed water temperature has changed significantly from the previous test results (e.g.
>1˚K), record the change and before resetting the mixed water temperature check that:
2.1 All the strainers are clean.
2.2 All the check valves are in good working order.
2.3 The isolation valves are fully open.
3 If the mixed water temperatures are acceptable, carry out the following:
3.1 Record the temperature of the hot and cold water supplies.
3.2 Record the temperature of the mixed water from the basin tap.
3.3 Isolate the cold water supply to the mixing valve and monitor the mixed water
temperature.
3.4 Record the maximum temperature achieved as a result of (3.3) and the final
temperature (the final temperature should not exceed the values quoted in table 2)
3.6 Record the equipment used during these tests.
4 If the mixed water temperature is greater than the values quoted in table 2 or the maximum
temperature exceeds the corresponding values from previous test results by more than 2˚K,
the basin tap must be serviced.
5 After a period of between 12 to 15 weeks from commissioning, carry out the sequence of
tests as described in Maintenance sections 1, 2, 3 and 4.
