1. Sticking location for manufacturer’s label: For indoor unit: on the bell mouth inside suction grille. For decoration panel: on the inner frame inside suction grille.
2. In case of using Infrared remote control, this position will be a signal receiver. Refer to drawing of Infrared remote control for details.
3. When the temperature and humidity in the ceiling exceeds 30°Cand RH 80% or the fresh air is inducted into the ceiling or the unit continues 24 hours operation,
an additional insulation is required. (Thickness 10mm or more of glaswool or PE foam)
4. Though the installation is acceptable upto maximum of 660 mm square ceiling opening, keepa clearance of 45 mm or less between the main unit and the ceiling opening,
so that the panel overlapcan be ensured.
