4. HOW TO INSTALL THE OUTDOOR UNIT

4-1. Transporting

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. 4-1)

CAUTION

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.

4-2. Installing the Outdoor Unit

(1)Use anchor bolts (M12 or 15/32") or similar to securely anchor the unit in place. (Fig. 4-2)

(2)Be sure the rubber vibration insulator and platform extend to the inside of the legs. In addition, the washers used to anchor the unit from the top must be larger than the installation anchor holes. (Figs. 4-2 and 4-3)
