3. INSTALLATION PROCEDURE
3-1. Anchoring the outdoor unit
Transporting the outdoor unit by hoist:
For hoisting, pass the rope over the hoisting
brackets on the unit vase at 4 locations. (Fig. 15)
Insert wood separators as protective shielding
when using the hoist to prevent the outer casing
from being scratched or deformed by the rope.
Be sure not to touch or apply pressure on tube
connectors. (Fig. 15)
When hoisting with a crane, the crane hook
position must be 1 m or more above the unit.
•
Do not lay the outdoor unit on its side during transportation.
This can damage the devices and result in malfunction.

After cutting the tube, be sure to remove all burrs and
fi
nish tubing ends to the correct
surface. (The same must be done for branch tubes (purchased separately).)
When bending tubes, be sure the bend radius is at least 4 times the outer diameter
of the tube.
When cutting or bending tubes, be careful not to cause any pinching or blockage of
the tube.

•
Prevent foreign substances such as dirt or water from entering the tube by
sealing the end of the tubes with either a cap or with tape.
Otherwise, this can damage the devices and result in malfunction.
