-- Turn the switching nut (3) onto the threaded bush (2). Caution: Left-hand thread!
-- Maintain clearance to the bonnet (approx. 5 mm).
-- Take care to ensure that the slot in the switching nut (3) is located on the side where the mounting bracket (1) is to be fitted.
If the switching nut (3) does not fit properly, check the grub screws (8) and their installed depth (Fig. 4) and turn them in somewhat
more deeply if necessary.
Do not turn the grub screws (8) in too far, as this could cause malfunctioning.
-- Use a hexagon head bolt (6) and spring washer (16) to attach the fixing plate (4) to the threaded bush.

The following procedure shall be adhered to:
-- If the valve is installed in the system, valve pressure must be released and the valve must be allowed to cool down to below the
fluid’s evaporation temperature in all areas in contact with the fluid in order to effectively prevent any risk of scalding.
-- Preferably, the bracket should be mounted to the left or right of the pipe, but it can also be mounted to the left or right of the
handwheel, i.e. normal to the pipe axis.
-- Unscrew and remove the studs one at a time, and replace each of them in turn with a loosely tightened hexagon head bolt (14)
– together with the bracket (1), of course.
-- Do not yet tighten the hexagon head bolts (14) all the way!
