PLACEMENT CONSIDERATIONS

Indoor Unit

Do’s

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 impact operation. Maintain proper distances between

the indoor units and electric wires, audio and visual appliances,

breaker / circuit panels, etc.

• Place in an area that is level and with enough strength to bear the

weight of the indoor unit(s).

Do Not’s

• 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
