Bracket mounting
Mount the bracket to the regulator as shown in the picture.
Assemble so that the rotation stopper of the regulator and
the bracket are engaged properly.
Secure with the set nut
Ensure that the knurled faces of the bracket and the set
nut are facing each other.
Tightening
Turn the set nut while the regulator is aligned correctly
with the bracket. The knurling of the bracket and set nut
stops loosening of the screw. Usually, these can be
tightened adequately by hand. (Extra tightening is
recommended for panel mounting).
Please use a hook wrench on the grooves of the set nut.
After hand tightening, follow the values in the table below
for retightening.
