Installation of the unit
21 21
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 50mm 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 20mm. (Refer to the figure.)
•
If overturning prevention is required, purchase the necessary commercially
•
available items.
