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.
Ceiling Height Mode Selection
≤7-1/2 feet Low Ceiling
7-1/2 feet to 8-7/8 feet Standard
8-7/8 feet to 10-3/16 feet High Ceiling
10-3/16 feet to 11-13/16 feet Very High Ceiling
Table 36: Indoor Unit High Ceiling Mode Selection Options
(LCN098HV4, LCN128HV4, LCN187HV, LCN188HV4, LCN247HV).
Ceiling Height Mode Selection
≤8-7/8 feet Low Ceiling
8-7/8 feet to 10-1/2 feet Standard
10-1/2 feet to 11-13/16 feet High Ceiling
11-13/16 feet to 13-13/16 feet Very High Ceiling
Table 37: Indoor Unit High Ceiling Mode Selection Options (LCN367,
LCN427HV ).
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.
• Indoor units (IDUs) should not be placed in an environment where the IDUs may be exposed to harmful volatile organic compounds (VOCs) or
in environments where there is improper air make up or supply or inadequate ventilation. If there are concerns about VOCs in the environment
where the IDUs are installed, proper air make up or supply and/ or adequate ventilation should be provided. Additionally, in buildings where
IDUs will be exposed to VOCs consider a factory-applied epoxy coating to the fan coils for each IDU.
• 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.
