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
away).
