4.4 INSTALLATION THE UNIT
• Install 4 or more anchor bolts at the 8 locations indicated by arrows. (Fig. 4.4-1)
• Keep the left and right anchor bolts 850 mm or more apart from each other.
This does not apply when anchor bolts are installed in all 8 locations.
• To reduce vibration, do not install the unit directly on the ground.
Instead, install it on a secure base (such as concrete blocks). (Fig. 4.4-2) Depending on the installation conditions, the unit may
spread its vibration during operation, which may cause noise and vibration.
Therefore, attach damping materials (such as damping pads) to the unit during installation.
• If you will be installing a foundation, be sure to take the routing of the pipe connections into account.
• Before securing the unit, make sure the anchor bolts are tightened securely.

3 The number of outdoor units that may be connected is 1 system (3 units connected) (Fig. 4.3-5).
• To install more than 1 outdoor unit system, provide a distance between each refrigerant system.
• Do not install walls at the sides.
