6.INSTALLATION

- The installer must protect the power line drive disconnecting devices

circuit breaker suitable for installation in accordance with the legislation.

-

- The power to the unit must be within a range of voltage (see table consumption electric page 8).
- It should pay special attention to the connection of ground wire. The ground wire must be of a

larger than the cable phases.

.

- Remove the access panel to the control panel located on the front side of the unit.

- Check that the network characteristics match the data on the nameplate of the unit.

- Perform power and interconnection between the interior and exterior units through the 2 presses on the side of

In the indoor unit:

Before commissioning of the unit must perform the following connections:

- Mains supply (outdoor unit), Figure 8.

- Interconnection between the outer and inner drive, figures 8.
