3. Electrical box may be removed for service purposes.

Make sure to slack the electrical wire little bit for control/power wires connection.

4. The height of the indoor unit is adjustable with the grille attached.

5. For the installation of the optional high efficiency filter, the optional multi-functional casement is required.

1) Add 5-5/16 (135mm) to the dimensions marked with an * in the figures

2) The optional high efficiency filter required optional multi-functional casement.

6. When installing the branch ducts, be sure to insulate adequately.

Otherwise condensation may occur.

7. As for necessary installation/service space, please refer to the bottom left figure.
