• Use suspension ropes that will withstand the weight of the unit.
• When moving the unit, use a 4-point suspension, and avoid giving impacts to
the unit (Do not use 2-point suspension).
• Place protective pads on the unit where it comes in contact with the ropes to
protect the unit from being scratched.
• Set the angle of roping at 40˚ or less.
• Use 2 ropes that are each longer than 8 m [26ft].
• Place protective padding at the corners of the product to protect the product
from scratches or dents that might be caused by the rope.
Caution:
Be very careful when carrying/moving the product.
- When installing the outdoor unit, suspend the unit at the specified location of the
unit base. Stabilize as necessary so that it does not move to the side and support
it at 4 points. If the unit is installed or suspended with 3-point support, the unit
may become unstable and fall.
• Fix unit tightly with bolts so that unit will not fall down due to earthquakes or strong winds.
• Use concrete base or an angle bracket as the foundation of unit.
• Vibration may be transmitted to the installation section and noise and vibration may
be generated from the floor and walls, depending on the installation conditions.
Therefore, provide ample vibrationproofing (cushion pads, cushion frame, etc.).
• Build the foundation in such way that the corner of the installation leg is securely
supported as shown in the left figure. (Fig. 8.1.1)
When using a rubber isolating cushion, please ensure it is large enough to
cover the entire width of each of the unit's legs. If the corners are not firmly
seated, the installation feet may be bent.
• When using cushion pads, be sure that the full width of the unit is covered.
• The projecting length of the anchor bolt should be less than 30 mm [1-3/16 in].
• Post-installed anchor bolts (i.e., bolts not firmly cemented into the base) are
not compatible with this product unless fixing brackets are first mounted on the
four locations.
