10 UNITS INSTALLATION
10.1. OUTDOOR UNITS INSTALLATION
 CAUTION:
Transport the products as close to the installation location as
practical before unpacking.
Do not put any material on the products.
Apply four lifting wires on to the outdoor, when lifting it by crane
 WARNING:
- Install the outdoor unit with sufcient clearance around it for
operation and maintenance as shown in the next gures.

- For cleaning, use noninammable and nontoxic cleaning liquid.
Use of inammable agent may cause explosion or re.
- Work with sufcient ventilation, for working in an enclosed space
may cause oxygen deciency. Toxic gas may be produced when
cleaning agent is heated to high temperature by, e.g., being
exposed to re.
- Cleaning liquid shall be collected after cleaning.
- Pay attention not to clamp cables when attaching the service
cover to avoid electric shock or re.
CAUTION:
Keep clearance between the units of more than 50mm, and avoid
obstacles that may hamper air intake, when installing more than
one units together.
Install the outdoor unit in the shade or not exposed to direct
sunshine or direct radiation from high temperature heat source.
Do not install the Outdoor Unit in a space where a seasonal wind
directly blows to the Outdoor fan.
