4. Remove the inlet filter and record the incoming water temperature. The
temperature of the water must be within the range of 5 - 20º C.
5. Clean, or if necessary renew, and refit the inlet filter.
6. Switch on the electrical supply and record the voltage at the terminal block. The
voltage must be in the range 230V ±10%. Isolate the electrical supply.
7. Turn on the water supply and check for leaks. Hold down the air bleed button to
prime the shower (see Installation - Priming the Shower).
8. Remove the showerhead from the hose. Position the end of the hose to allow

minutes, then record the water temperature and rate of flow as described in step
14. If the shower will not run continuously, return to step 16.
18. When all tests have been performed and recorded, stop the shower. Isolate the
electrical supply and open the isolating valve fully. Ensure the cover is correctly
