Please use a hook wrench on the grooves of the set nut.
After hand tightening, follow the values in the table below
for retightening.
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.
Ensure that the knurled faces of the bracket and the set
nut are facing each other.
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).
Fix the bracket B with the set screw (2 pcs.) included in
the package. Refer to the table below for the tightening
torque.
Insert bracket A from the front of the regulator so that the
fingers of the bracket A hold the regulator at the groove
and the bottom of the body.
