• To guarantee the smooth running of the thermostat, it is necessary
from time to time to turn the thermostat from total hot to total cold.
• The mixer is equipped with check valves. The check valves must be
checked regularly according to DIN EN 1717 in accordance with
national or regional regulations (at least once a year).
Adjustment
(see page 32)
After the installation, the output temperature of the thermostat must be
checked. A correction is necessary if the temperature measured at the
output differs from the temperature set on the thermostat.
Safety Function
(see page 33)
The desired maximum temperature for example max. 42º C can be pre-
set thanks to the safety function.
