WHAT TO DO IF THINGS GO WRONG (1) SELF HELP If the shower is not working satisfactorily, make the following checks before calling out the installer. Any one of these adjustments could restore the performance. The shower cycles from HOT to COLD Water too HOT Water too COLD Spray pattern poor Water takes longer to heat up Water goes cold while using shower Broken parts Water continues to flow when button “D” pressed to stop Temperature is set too hot causing the thermal cut-out (safety device) to operate.
HOW YOUR SPA300C SHOWER WORKS 1. Water is heated instantaneously as it flows over the heating elements in the copper cylinder (Diagram 6). 2. The heaters are only switched on when sufficient water is flowing. This is done automatically with a switch which works on water pressure and is indicated by the LED indicator illuminating. 3. The water is turned on and off by the solenoid valve and Control PCB built into the shower. This is switched on when button “A”, “B” or “C” is pressed. 4.
