figure.
• Use sufficiently strong rope to bear the unit's weight.
• Place protective board or filler cloth at the place where the cabinet may come into
contact with the rope to prevent damages. Without using them, the cabinet may be dam-
aged 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 an accident caused by the unit swinging or falling down, do not apply any
impact to the unit when it is hanging.
• When hoisting, do not hook the rope to the thermistor holder on the back of the outdoor
unit.

3.5. Installing the unit

• Please install the outdoor unit without slant. (within 0.3 degrees)
• 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 3 in (80 mm) or more.
• Depending on the installation conditions, the outdoor unit may spread its vibration during
20 (500)
operation, which may cause noise and vibration. Therefore, attach damping materials
or more
(such as damping pads) to the outdoor unit during installation.
• Install the foundation, making sure that there is enough space for installing the connec-
119 (3000)
tion pipes.
or more
• 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 13/16 in (20 mm). (Refer to the figure.)
• If overturning prevention is required, purchase the necessary commercially available
items.
7-11/16 (195)

• Do not install directly on the ground, this may result in equipment failure.
• The drain water is discharged from the bottom of the equipment. Construct a drain ditch
around the base and discharge the drain water properly.
• Provide ample space for ice buildup from condensate between the bottom of the unit and
the flat surface on which it is mounted. Otherwise, there is risk that the drainage water
will freeze between the device and the surface, disabling drainage.
