Unit Installation

Minimizing Vibration

When installing multiple mini outdoor units side by side, or when there is a need to minimize unit

vibrations, use a vibration-minimizing structure such as an H-beam frame or a vibration-isolation

frame, and an isolation pad. Refer to the specifications in Figure 5.

After installation, apply corrosion-protection to the frame.

Figure 5. Vibration-minimizing structure specifications

After installing a vibration-isolation frame, loosen the bolts so that the isolators are capable of

absorbing vibrations (Figure 6).

Securing the Mini Outdoor Unit

The mini outdoor unit must be secured so that it can withstand a wind speed of 67 mph (30 m/s).

Secure the unit firmly to the base with M10 anchor bolts (see Figure 7).

• Use zinc-plated or stainless steel nuts and bolts.

• Use a rubber washer between the bolt and the unit to prevent bimetallic corrosion.
