If ordered, the valve drives are factory-installed in the Multicolumn Thermostat. The valve heads are interchangeable and can be easily mounted.
At the first installation, the transportation lock and the dummy valve have to be removed, see Remove the Transportation Lock and the Valve Dummy. The valve heads can be installed by mounting the valve heads onto the valve drives and fastening the nut manually (do not use any tools).
Be sure that the guide pin snaps into the groove of the valve drive thread.
NOTE
The valves are mounted on pull-out rails to allow easy installation of capillaries. Push the valve gently into its housing until it snaps into the inner position, push it again and it slides out.
When all capillaries are installed, push the valve back into its housing, see Install the Valve Head and Connect Capillaries.
