• The mounting plate is the device on which you 
will mount the indoor unit.
1. Remove the screw that attaches the mounting plate to 
the back of the indoor unit.
2. Place the mounting plate against the wall in a location 
that meets the standards in the Select Installation Location 
step. (See Mounting Plate Dimensions for detailed 
information on mounting plate sizes.)
3. Drill holes for mounting screws in places that:
• have studs and can support the weight of the unit.
• correspond to screw holes in the mounting  plate.
4. Secure the mounting plate to the wall with the screws 
provided.
5. Make sure that mounting plate is flat against the wall.
