2.5 Installing Outdoor Unit

2.5.1 Installation Notes

1. Install the outdoor unit in a place which is secure and easy for maintenance. Do not install it on ground-level sites
with public access and be away from residential areas.
2. Do not locate it directly in the environment that requires low noise.
3. To ensure heat dissipation effect, locate it in a clean area, which is away from loose dirt and foreign matter to avoid
clogging the heat exchanger.
4. Do not locate it in the vicinity of steam, hot air and exhausts.
5. Keep a clearance of more than 450mm between the outdoor unit and the wall, obstruct and adjacent devices.
6. Avoid areas where snow will accumulate at air-inlet side and air-outlet side of the outdoor unit.
7. Prepare a solid base capable of supporting the outdoor unit weight (see Table 2-2). The base should be at least
50mm higher than the surrounding ground and 50mm larger than the dimensions of the outdoor unit base, as shown
in Figure 2-11.

2.5.2 Installation Procedure

1. Place the outdoor unit on the base.
2. Secure the outdoor unit onto the base with expansion bolts. The installation hole sizes of the base are shown in
Figure 2-9 and Figure 2-10.
