necessary.
Saving water resources:
▶ Make sure you close all the taps after any use. Avoid leaving the taps
dripping. Repair any leaking tap.
▶ Define the temperature you want, in the appliance or with the remote
control. This way you have the precise water flow needed (mixing
cold water to regulate temperature will increase the water flow with
consequent waste of water).
The water heater will not ignite if inlet water temperature exceeds the set
point temperature less 9 °F (5 °C). In this condition, the solar mode
indicator will show on the LCD display. See fig. 51, page 35.
