Installation and maintenance
NOTE! Must be installed on the supply line (incoming heat), never on the return line!
NOTE! Take note of the flow direction arrow!
Manoeuvre the thermostatic valve pin once a month to prevent it from sticking. This is particularly important after summer, as the flow has been shut off for a long period. Remove the thermostat dial and push in the pin manually a few times. If the pin has become stuck, lightly tap the valve housing.
