Start-up
• Compression fitting: The thermostatic head is held in place by a
mounting ring, which is held together with a screw. Loosen this
screw and remove the thermostatic head from the valve.
• Threaded connection with set screw: Loosen the set screw and
remove the thermostatic head.
5.2.2 Mounting the radiator thermostat
After removing the old thermostatic head, you can mount the new radi-
ator thermostat on the heating valve:
• Place the radiator thermostat with the metal nut
(A)
on the heat-
ing valve (see figure 7) .
• Tighten the metal nut on the radiator valve (see figure 8) .
If required, you can use one of the supplied adapters for Danfoss
valves (see see „5.2.4 Adapter for Danfoss“ on page 49) or the
supplied support ring (see see „5.2.3 Support ring“ on page 49).
5.2.3 Support ring
With some manufacturers' valves, the part of the valve that protrudes into
the device has only a small diameter, which causes the radiator thermo-
stat to sit more loosely on the valve. In this case, the supplied support
ring should be inserted into the flange of the device before mounting
(see
figure 9) . You can then mount the radiator thermostat again as described
above.
5.2.4 Adapter for Danfoss
One of the adapters supplied is required to attach to Danfoss valves. The
assignment of the suitable adapter to the relevant valve is shown in the
following illustrations.
Please be careful not to trap your fingers between the two halves of
the adapter!
The RA and RAV adapters have been manufactured with pre-tension for a
better fit. Use a screwdriver during installation if necessary, and bend the
adapter open slightly in the vicinity of the screw
(see following figures) .
