CAUTION
When carrying the unit, hold the handles on the right and left sides and be careful.
If the outdoor unit is carried from the bottom, hands or

fi
ciently strong rope to bear the unit’s weight.
• Place protective board or
fi
ller cloth at the place where the cabinet may come into
contact with the rope to prevent damages. Without using them, the cabinet may be
damaged or deformed.
• The center of gravity of the outdoor unit is shifted to the right. Be careful not to tilt to
the heavy side causing it to fall.
• To prevent accidents caused by the unit swinging or falling down, do not apply any
impact to the unit when it is hanging.

3.5. Installing the unit
• Install 4 anchor bolts at the locations indicated with arrows in the figure.
• To reduce vibration, do not install the unit directly on the ground. Install it on a secure
base (such as concrete blocks).
• The foundation shall support the legs of the unit and have a width of 80 mm or more.
• Depending on the installation conditions, the outdoor unit may spread its vibration during
operation, which may cause noise and vibration. Therefore, attach damping materials
(such as damping pads) to the outdoor unit during installation.
• Install the foundation, making sure that there is enough space for installing the connec-
tion pipes.
• Secure the unit to a solid block using foundation bolts. (Use 4 sets of commercially avail-
able M10 to M12 bolts, nuts, and washers.)
• The bolts should protrude 20 mm. (Refer to the figure.)
• If overturning prevention is required, purchase the necessary commercially available
items.
