MOUNTING PLATE DIMENSIONS
Different models have different mounting plates. 
For the different customization requirements, 
the shape of the mounting plate may be slightly 
different. However, the installation dimensions 
are the same for the same size of indoor unit. 
See the illustrations for Type A and Type B below 
for an example. In order to ensure that you have 
ample room to mount the indoor unit, the 
diagrams to the right show different types of 
mounting plates along with the following 
dimensions:
 • Height & Width of mounting plate
 • Height & Width of indoor unit relative to 
 plate
 • Recommended position of wall hole (both 
 to the left and right of mounting plate)
 • Relative distances between screw holes
