Selecting the Best Location for the Indoor Unit
Follow recommended best practices when choosing an indoor location for the
single zone indoor unit.
Dos
• Follow the table at right for minimum clearance of indoor unit from the top of
the unit to the ceiling.
• Clearance gap between any wall or enclosure and the left or right side of the
unit must be greater than 4 inches. Ensure there is sufficient maintenance
space.
• Unit must be at least 6-1/2 feet from the floor for adequate clearance.
• Place the unit where drainage can be obtained easily. Condensation drain
must be conveniently routed away from the unit.
• Locate the indoor unit in a location where it can be easily connected to the
outdoor unit within allowable limits.
• Use a metal detector to locate studs in the walls. Anchor unit following stud
location to prevent damage to the wall.
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 will 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.
• Do not install in an area where operation sound will disturb occupants--place the unit where noise prevention is taken into consideration
• Do not install near doorway.
• Avoid installing the unit near high-frequency generators.
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 will be damaged, will 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 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
environment 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 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 [3] degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.
