Selecting the Best Location
Do’s
• Place the unit where air circulation will not be blocked.
• Place the unit where drainage can be obtained easily.
• Place the unit where noise prevention is taken into consideration.
• Ensure there is sufficient space from the ceiling and floor.
• Ensure there is sufficient maintenance space.
• Locate the indoor unit in a location where it can be easily connected to the outdoor
unit / branch distribution unit.
Don’ts
• The unit should not be installed near a heat or steam source, or where considerable amounts of oil, iron powder, or flour are used.
• The unit should not be installed where sulfuric acid and flammable or corrosive gases are generated, vented into, or stored.
• Avoid installing the unit near high-frequency generators.
• Do not install the unit near a doorway.
The unit may be damaged, may malfunction, and / or will not operate as designed if installed in any of the conditions listed.
Installation and Best Layout Practices
Using the Installation Guide
1. Choose an appropriate location for the indoor unit. To hang the installation guide, verify that it is level
and plumb, and then tape it to the wall.
2. Drill four (4) 1/4-inch diameter holes with a depth of 1-3/16 to 1-3/8 inches for the mounting screws.
Drill one (1) two (2) inch-diameter hole for the field-installed refrigerant and drain piping.
3. Insert a plastic anchor into each of the mounting holes.
4. Screw the top two (2) screws into the wall. Do not flush them to the wall; leave a 7/16 inch space for
hanging the indoor unit.
Figure 49:Using the Installation Guide.
If the unit is installed near a body of water, certain components are at risk of being corroded.
Appropriate anti-corrosion methods should be taken for the unit and all components.

Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas(floors, walls) in some rooms may be exposed to uncondi-
tioned air (room may be above or next to an unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet may increase the temperature by three degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.
