3.4. Transporting the unit
WARNING
Do not touch the
fi
ns. Otherwise, personal injury could result.
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
ngers may be pinched.
• Carry slowly in the manner as shown on “Fig. B” holding the handles “Fig. A” in right and
left sides. (Be careful not to touch with hands or objects.)
• Be sure to hold the handles on the sides of the unit. Otherwise, the suction grilles on the

3.5. Installing the unit
• Please install the outdoor unit without slant. (within 3 degrees )
• Install 4 anchor bolts at the locations indicated with arrows in the
fi
gure.
• 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 50 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 bolts, nuts, and washers.)
• The bolts should protrude 20 mm. (Refer to the
fi
gure.)
• If overturning prevention is required, purchase the necessary commercially available
items.

Base
Do not install directly on the ground, this may result in equipment failure.
Provide ample space for ice buildup from condensate between the bottom of the unit and
the
fl
at surface on which it is mounted.
Otherwise, there is risk that the drainage water will freeze between the device and the
surface, disabling drainage.

CAUTION
If the unit is installed in a region that is exposed
to high winds, freezing conditions, freezing rain,
snow fall or heavy snow accumulation, take
appropriate measures to protect it from those ele-
ments.
To ensure stable operation, the outdoor unit must
be installed on a raised stand or rack, at or above
the anticipated snow depth for the region.
The installation of snow hoods and drift preven-
tion fencing is recommended when blowing and
drifting snow is common to the region.
