NOTES:
• If the space is larger than stated above, the condition will be the same as when there
is no obstacle.
• When installing the outdoor unit, be sure to open the front and left side to obtain
better operation eciency.
3.2. Mounting the unit
• Install 4 anchor bolts at the locations indicated with arrows in the 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 gure.)
• If overturning prevention is required, purchase the necessary commercially available
items.
