Proliferation of legionellae

WARNING!

Proliferation of legionellae due to stagnant water!

If the unit is not used for an extended period, there

is a risk of the proliferation of legionellae due to

stagnant water.

– Upon restarting, set the operating mode to

“Thermal disinfection” (2 = Legio) to flush the

drinking water lines with hot water (

Ä Chapter

6.3 ‘Setting the operating mode’ on page 25).

Legionellae are bacteria of which one species is

harmful to humans. Legionellae can easily proliferate

in pipes with warm, stagnant water. Flushing the

pipes at a water temperature of at least 55 °C kills off

the legionellae.
