Maintenance Procedure - Inlet Strainers
Blockage of the inlet strainer screens can lead to poor flow performance and reduced
temperature control. It is essential that the inlet strainer screens are cleaned or, if
necessary, renewed as part of the six-monthly maintenance operations.
A Strainer pack is available for the Exact-3 B, containing 2 strainer screens and 2
retainers.
1.
Isolate the supplies to the shower control, and open the flow control to release
pressure and to assist the draining of residual water.
2.
The strainer screens are located at the inlet of each Checkvalve cartridge.
To access the inlet strainer screens remove the checkvalve cartridges.
3.
The strainer screens are dished outwards and are held in position by the rubber
retainers. Remove carefully.
4.
The strainer screens may be cleaned under a jet of water, or renewed.
5.
Re-assembly into the shower control is a reversal of the previous procedures.
Do not overtighten
when re-inserting cartridges.
6.
Restore the water supplies, and check for leaks.
