Foundation for Installation
• Fix the unit tightly with bolts as shown below so that the unit will not fall down due to earthquake.
• Noise and vibration may occur from the floor or wall since vibration is transferred through the in-
stallation part depending on installation status. Thus, use anti-vibration materials (cushion pad)
fully (The base pad shall be more than 200 mm (7-7/8 inch)).

• Check the strength and level of the installation ground so that the unit will not cause any
operating vibration or noise after installation.
• Fix the unit securely by means of the foundation bolts. (Prepare 4sets 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 20mm from the foundation
surface.
