WARNING!
RISK OF SCALDING
For thermal disinfection, the entire DHW
system is set at the factory to heat up to
70 °C (start: Tuesday night at 01:00).
z If required (e.g. shift work), your
heating contractor can alter the start
time.
z During this time, never open any hot
water tap without mixing in cold water if
the DHW circuit of your heating system
is not equipped with a thermostatic
mixer.
z As there is a risk of scalding at
temperatures above approximately
60 °C, ask your heating contractor
about the set DHW temperatures.
CAUTION!
SYSTEM DAMAGE
from frost.
When the heating system is switched off,
it can suffer damage from frost.
z Protect your heating system against
frost damage by draining it and the
DHW pipework at the lowest possible
point.
