Application Guidelines

PLACEMENT CONSIDERATIONS

Indoor Unit

Select a location for installing the indoor units that will meet the following conditions:

• Place the unit where air circulation will not be blocked.

• Locate the indoor unit in a location that is level, and where it can be easily connected to the outdoor unit.

• Place the unit in a location where condensation drainage can be conveniently routed away.

• Include enough space around the indoor unit so that it is accessible for maintenance and service purposes.

• Place the unit in a location where electrical noise / electromagnetic waves will not affect operation. Maintain proper distances between the

indoor units and electric wires, audio and visual appliances, breaker / circuit panels, etc. If the frequency signal of the appliance is unstable,

then install the indoor unit a minimum of ten (10) feet away, and run the power and transmission cables through a conduit.

• Place in an area that is level and with enough strength to bear the weight of the indoor unit(s).

Don’ts

• No obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.

• 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).

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.

The unit should not be installed where sulfuric acid and ammable or corrosive gases are generated, vented into, or stored. There is risk of

re, explosion, and physical injury or death.

Selecting the Best Location for the Indoor Unit

The unit may be damaged, may malfunction, and / or will not operate as designed if installed in any of the conditions listed.
