2 Unit installation
2 Pull down the U-shaped hook (at 2 positions) located at the indoor unit side.
3 Mount the air panel temporarily. Fit the corner position of the refrigerant pipe connection at the indoor unit and the
position stamped as "Ref. Pipe ". Then, catch the C-shaped hinges (2 portions) onto the U-shaped hooks (2 portions).
4 Fix the air panel to the fixing plate by factory supplied long screws (M6 cross screws).
5 Tighten the long screws until touching the stopper to the fixing plate. Check to ensure that the distance between the
fixing plate undersurface and the corner panel undersurface is 26mm.
6 When tightening the long screws to prevent air leakage and to be no gap between the false ceiling surface and the
indoor unit, the inner circumference of the air panel (the position to attach the air inlet grille) may be slightly deformed.
However, it is not abnormality.
