Selecting the Best Location
Do’s
• Place the unit where air circulation will not be blocked.
• Place the unit where drainage can be obtained easily.
• Place the unit where noise prevention is taken into consideration.
• Ensure there is sufficient space from the ceiling and floor.
• Ensure there is sufficient maintenance space.
• Locate the indoor unit where it can be easily connected to the outdoor unit or branch
distribution unit.
Don’ts
• Do not install the unit near a heat or steam source, or where considerable amounts of oil,
iron powder, or flour are used.
• Do not install the unit where sulfuric acid and flammable or corrosive gases are generated,
vented into, or stored.
• Do not install the unit near high-frequency generators.
• Do not install the unit near a doorway.
The unit will be damaged, will malfunction, and / or will not operate as designed if
installed in any of the conditions listed.
Installation and Best Layout Practices
Selecting Installation Method
The unit can be installed in one of three configurations:
• On the floor.
• Mounted on the wall above floor molding.
• Half concealed (recessed) in an opening in the wall.
Figure 105:Floor Installation
If the unit is installed near a body of water, certain components are at risk of being corroded. Appropriate anti-corrosion methods must be taken for the
unit and all components.
LOW WALL CONSOLE INDOOR UNITS
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms will be exposed to unconditioned air (room will be above or next to an
unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet will increase the temperature by three degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.
• Indoor units (IDUs) must not be placed in an environment where the IDUs will 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 third party factory-applied epoxy coating to the fan coils for each IDU where the entire coil
is dipped, not sprayed.
• 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.
