Usage recommendations

Before installation, verify that your radiator valve matches the M28 x 1.5 mm thread specification and that the electronic valve drive uses an M30 x 1.5 mm thread. If in doubt, consult the valve or actuator manufacturer documentation. Periodically inspect the adapter and threaded connections for corrosion or wear and replace if necessary.
