Placement Considerations; Indoor Unit - LG LH247HV Engineering Manual

Selecting the Best location for the indoor unit
Do's
Select a location for installing the indoor units that will meet the following conditions:
• No obstacles to air circulation around the indoor unit; keep proper distances from ceilings, doorways, floor, walls, etc.
• So that condensation drainage can be conveniently routed away.
• Include enough space around the indoor unit so that it is accessible for maintenance and service purposes.
• Where electrical noise / electromagnetic waves will not affect indoor unit 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.
• An area that has sufficient strength to bear the load of the indoor unit.
• An area where operation sound won't disturb occupants.
• An area that does not expose the indoor unit to heat, water, steam, oil splattering or spray.
• Locate the indoor unit in a location that is level, and where it can be easily connected to the outdoor unit.
don'ts
• The indoor unit should not be installed near a heat or steam source, or where considerable amounts of oil, iron powder, or flour are used.
• The indoor unit should not be installed where sulfuric acid and flammable or corrosive gases are generated, vented into, or stored.
• Avoid installing the indoor unit near high-frequency generators or near any equipment that generates an electromagnetic field (minimum
3-1/3 feet away).
• Do not install the indoor unit near a doorway.
the indoor unit may be damaged, may malfunction, and / or will not operate as designed if installed in any of the
conditions listed.
If the indoor 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 indoor unit and all components.
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms may be exposed to unconditioned air (room may be above or next to an
unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet may increase the temperature by three degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.
Installing in an Area with High Humidity Levels
If the environment is prone to humidity levels of 80% or more (near the ocean, lakes, etc.) or where steam could collect in the plenum:
• Install additional insulation to the indoor unit (glass wool insulation >13/32 inches thick).
• Install additional insulation to the refrigerant piping (insulation >13/16 inches thick).
• Seal all gaps between the indoor
conditioned space. Also, add a ceiling grille for ventilation.
