• The whole of the base of the YUTAKI unit should be
installed on a foundation. When using vibration-proof
mat, it should also be positioned the same way. When
installing the YUTAKI unit on a field-supplied frame,
use metal plates to adjust the frame width for stable
installation as shown in the figure below.

• The foundation drawing shown previously is an
example.
• The unit is low-vibration model, but consider using
some floor reinforcement or anti-vibration mat/
rubber when vibration should occur due to weakness
of attached surface.
• The foundation shall be unified with the floor slab. If
not, calculate the vibration proof of the installation
of YUTAKI unit as well as of the YUTAKI unit with the
foundation in order to ensure strength against a fall
or for when the unit has to be moved.
• Drain water and rainwater are discharged from the
bottom of the unit when in operation as well as when
stopped.
• Choose a location with good drainage or place a
water drain as in the drawing.
• Make the foundation flat and waterproof, as a water
pool may appear in case of, for instance, rain.
• This is a low-profile product with a shallow depth. It
may also be able to fix on the wall as shown below
when fixing only with the foundation bolt does not
seem sufficiently stable depending on the conditions
of the installation. (Metal fittings must be field
supplied).
◆ Fix unit to the wall
Both sides can be fixed to the wall.
(Metal fittings are field supplied)
1. Fix the unit onto the wall as indicated in the figure.
(Stay field supplied).
2. The foundation shall be strong enough to avoid any
deformation and vibration.
3. In order to prevent vibration transfer to the building,
place rubber material between the stay and the wall.
