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.

Mounting the Installation Plate
The mounting wall should be strong and solid enough to protect the unit from vibration.
• Mount the installation plate on the wall using the Type “A” screws. If mounting the unit on
concrete, consider using anchor bolts.
• Always mount the installation plate horizontally. Measure the wall and mark the centerline
using thread and a level.

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.

Installation and Best Layout Practices
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas(floors, walls) in some rooms may be exposed to unconditioned 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.
Due to our policy of continuous product innovation, some specications may change without notication.
