(3) Direction of the air discharge

• Select the number of directions of the optimum air discharge for the shape or the position of the room.

• Directions of the air discharge can be changed by installing a sealing material.

• When installing a sealing material, the field setting from the remote controller is required. For details,

refer the operation manual attached to the sealing materials.

(4) Use suspension bolts for installation. Check whether the ceiling is strong enough to support the

weight of the unit or not. If there is a risk, reinforce the ceiling before installing the unit.

(Installation pitch is maked on the paper pattern for installation. Refer to it to check for points requiring reinforcing.)

4. PREPARATIONS BEFORE INSTALLATION

(1) Relation of ceiling opening to unit and suspension bolt position. Refer to Fig. 4 – 7. (Unit: mm)

CAUTION

Reduce the distance between the unit and ceiling to 35 mm or below in order to maintain an overlapping

panel margin of 20 mm for the opening on the ceiling. If the distance exceeds 35 mm, attach a ceiling

material to the part marked or replace the ceiling (see Fig. 6).
