DIMENSIONS AND CLEARANCES
If you install the unit on the ground or on a concrete mounting platform, perform the following steps.
1. Mark the positions for four expansion bolts based on the dimensions
chart.
2. Pre-drill holes for expansion bolts.
3. Place a nut on the end of each expansion bolt.
4. Hammer expansion bolts into the pre-drilled holes.
5. Remove the nuts from expansion bolts, and place the outdoor unit on
bolts.
6. Put a washer on each expansion bolt, then replace the nuts.
7. Use a wrench to tighten each nut until snug.
NOTE: Drilling the Hole in the Wall
You must drill a hole in the wall for the refrigerant piping, and the signal
cable that will connect the indoor and outdoor units.
1. Determine the location of the wall hole based on the location of the
outdoor unit.
2. Using a 2.5in (65mm) core drill, drill a hole in the wall.
NOTE: When drilling the wall hole, ensure to avoid wires,
plumbing, and other sensitive components.
3. Place the protective wall cuff in the hole. This protects the edges of the
hole and helps seal it when you finish the installation process.
