If the instructions provided in this guide are not observed, the cooling system may not work properly and may cause
a malfunction, which will not be covered by warranty.
–
The ventilation opening ratio should be minimum 50 %.

Calculating the total area of the ventilation and ventilation opening ratio
Total area of the ventilation: 181 x 89 = 16,109 mm
Total open area of the ventilation holes: 20 x 20 x 32 = 12,800 mm

Partition design guide
•
For semi-outdoor units, add partitions between the inlet and outlet to keep air paths separated.
•
Partitions should fit perfectly inside the enclosure unit, with no gap between the semi-outdoor unit and enclosure
unit. If there is a gap, use a foam tape to fill it.
