In case of visible damage to the
existing thermostat, valve or heat-
ing pipes, please consult a spe-
cialist.
Remove the old thermostatic head
from your radiator valve:
• Rotate the thermostatic head an-
ticlockwise to the maximum value

longer presses against the valve
spindle, making it easier to remove.
