Verify the shower
The final step is to start the shower to verify that it works as intended.
Turn on the power and water supply. It takes about 1 minute for the Core to start up.
Start the shower and set the temperature to 25 °C.
Let the shower run, and check that the recirculation starts within 5 minutes. This should be displayed on the Control Dial screen.
Inspect all water connection points for leakage. Carefully check each connection point to ensure there are no leaks.
