4-8. Transporting the Outdoor Unit
When transporting the unit, have it delivered as close to the installation site as
possible without unpacking. Use a hook for suspending the unit. (Fig. 2-12)
When hoisting the outdoor unit, pass ropes or straps under the bottom plate
as shown in the figure at right. When hoisting, the angle between the rope
and top panel must be 70° or greater so that the rope does not come into
contact with the fan guard.
(Use 2 lengths of rope 25 ft. long or longer.)
When passing the ropes through the square holes of the bottom plate:
Place the rope in the outer edge of the square holes.
Use protective panels or padding at all locations where the rope contacts the
outer casing or other parts to prevent scratching. In particular, use protective
material (such as cloth or cardboard) to prevent the edges of the top panel
from being scratched.
Be careful of the fan.
There is danger of injury if the fan starts to turn during inspection. Be sure to
turn OFF the remote power switch before beginning inspection.
