Note:
When reinstalling the corner panels (each with a safety wire attached), con-
nect the other end of each safety wire to the grille using a screw (4 pcs,

*If the corner panels are not attached, they may fall off while the unit is operating.
• Perform the procedure that is described in “9.2. Preparing to attach the grille” in
reverse order to install the intake grille and the corner panel.
• Multiple units can be installed with grille so that the position of the logo on each
corner panel is consistent with the other units regardless of the orientation of the
intake grille. Align the logo on the panel according to the wishes of the customer
as shown in the diagram to the left. (The position of the grille can be changed.)
