Indoor unit
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 strength to bear the load of the indoor unit.
• Ensure there is sufficient maintenance space.
• Locate the indoor unit in a location that is level, and where it can be easily connected to the outdoor 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 or near any equipment that generates an electromagnetic field (minimum 3-1/3
feet away).
• 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.
Installing in a High or Dropped Ceiling
High or dropped ceilings, often found in commercial buildings and offices, may cause a wide temperature differentiation. To countermeasure:
• Change the indoor unit mode selection to allow for higher ceilings (see table).
• Install an air circulator.
• Set the air discharge outlet so that heated air flows in a downward direction.
• Use a dual door system to protect the building gate or exit.
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.
