3.3. Mounting the unit
• 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
connection pipes.
• Secure the unit to a solid block using foundation bolts. (Use 4 sets of commercially
available 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.

CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Oth-
erwise the drainage from the upper unit may form ice and cause a malfunction of the
lower unit.
• When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe.
If the drain pipe is used, the drain water in the pipe may freeze in extremely cold
climate.

or more
• 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 elements.
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.
