How Your Electric Shower Works Heated water is produced by adjusting the flow of cold water passed through a heater tank. The shower has three heater settings. The warmer the shower, the lower the flow rate and vice versa.
The Effect of Seasonal Changes For a cold shower select LOW. For a summer warm shower select MEDIUM. For a winter warm shower select HIGH. During extremes of mains water supply temperature, adjust heater setting to obtain a better showering temperature. The Effect of Other Water Devices Example of how shower temperature stabilizes due to pressure changes. Water inlet pressure fluctuations due to other draw offs (e.g. flushing toilet).
Using Your Shower Read the section “Important Safety Information” first. 1. 2. Switch on electrical supply. Light on the appliance comes on. Press START button. Light remains on. 3. 4. Set to desired position. Check water temperature before entering shower. 5. Allow 10-15 seconds for any temperature adjustments to reach the handset. 6. 7. Press STOP button.
