INSTALLATION

Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.

In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)

It is best to screw in the foundation bolts until their length are
20 mm from the foundation surface.
