PLACEMENT CONSIDERATIONS
Indoor Unit
Selecting the Best Location for the Indoor Unit
Follow recommended best practices when choosing an indoor location for the single zone indoor unit.
Dos
• 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 where drainage can be obtained easily. Condensation drain must be conveniently routed away from the unit.
• 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 is level and with enough strength to bear the weight of the indoor unit(s).
Dont's
• Do not install the unit near a heat or steam source, or where considerable amounts of oil, iron powder, or flour are used. (These materials
may generate condensate, cause a reduction in heat exchanger efficiency, or the drain to malfunction. If this is a potential problem, install a
ventilation fan large enough to vent out these materials.)
• Ensure there are no obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.
• Avoid installing the unit near high-frequency generators or near any equipment that generates an electromagnetic field (minimum 3-1/3 feet
away).
The unit must not be installed where sulfuric acid and flammable or cor-
rosive gases are generated, vented into, or stored. There is risk of fire,
explosion, and physical injury or death.
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) must 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 envi-
ronment where the IDUs are installed, proper air make up or supply and/ or adequate ventilation must 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, the installation parts are at risk of corroding. Appropriate anti-corrosion methods must be taken for
the unit and all installation parts.
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 [3] 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 unit and the ceiling tiles (make the area air tight) so that humidity does not transfer from the plenum to the
conditioned space. Also, add a ceiling grille for ventilation.
