• When routing the piping from the side of an outdoor unit, provide space for the piping.
• No more than 3 units must be installed side by side.
When 3 units or more are arranged in a line, provide the space as shown in the following
example when an obstruction is present also in the upward area.

3.4. Transporting the unit
Do not touch the fi ns. Otherwise, personal injury could result.
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
sides of the unit may be deformed.

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.

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.
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.
