ON again using the ON/OFF switch. That activates the trap filling
sequence ( page 59). Repeat the procedure several times until
condensate starts running out.

WARNING: Danger of scalding!
▶ In normal operation, it is recommended to limit the
DHW temperature to 122 °F (50 °C) to limit the risk
of scalding.
▶ Install a tempering valve if running DHW
temperatures above 104 °F (40 °C).
▶ Only use temperatures up to 158 °F (70 °C) for
thermal disinfection ( page 54).
If there is reason for concern for contamination from
bacteria such as Legionella, consider setting the DHW
thermostat to at least “e” (131 °F (55 °C)).
This setting ensures an economical and comfortable
DHW generation. Consult your local water department or
municipality for further information.
