When installing Central Station EX in a hospital or other facility where electromagnetic waves are
generated from nearby medical and/or electronic devices, be prepared for noise and electronic
interference Electromagnetic Interference (EMI). Do not install where the waves can directly radiate
into the electrical box, controller cable, or controller. Inverters, appliances, high-frequency medical
equipment, and radio communications equipment may cause Central Station EX to malfunction. The
operation of Central Station EX may also adversely affect these same devices. Install Central Station
EX at least approximately 3 meters away from such devices.
●
When a wireless controller is used, locate it at a distance of at least approximately 1 meter between
the indoor unit and electric lighting. If not, the receiver part of the unit may have difficulty receiving
operation commands.
●
Do not install the unit in any location where animals and plants can come into direct contact with the
outlet air stream. Exposure could adversely affect the animals and plants.
●
Do not install the unit in any place where oil can seep onto the units, such as table or seating areas in
restaurants, and so forth. For these locations or social venues, use specialized units with oil-resistant
features built into them. In addition, use a specialized ceiling fan designed for restaurant use. These
specialized oil-resistant units can be ordered for such applications. However, in places where large
quantities of oil can splash onto the unit, such as a factory, even the specialized units cannot be used.
These products should not be installed in such locations.
Installation Precautions
●
When installing Central Station EX into...
▫ A wall: Make sure the wall is strong enough to hold the product's weight. It may be necessary to
construct a strong wood or metal frame to provide added support.
▫ A room: Properly insulate any refrigerant tubing run inside a room to prevent "sweating" that can
cause dripping and water damage to wall and floors.
●
Do not install Central Station EX in the following places. Doing so can result in an explosion, fire,
deformation, corrosion, or product failure.
▫
Explosive or flammable atmosphere
▫
Where a fire, oil, steam or powder can directly enter Central Station EX, such as nearby or above
a kitchen stove.
▫ Where oil (including machinery oil) may be present.
▫ Where corrosive gases such as chlorine, bromine, or sulfide can accumulate, such as near a hot
tub or hot spring.
▫ Where dense, salt-laden airflow is heavy, such as in coastal regions.
▫ Where the air quality is of high acidity.
▫ Where harmful gases can be generated from decomposition.
●
Perform a test run to ensure normal operation. Safety guards, shields, barriers, covers, and protective
devices must be in place while the compressor/unit is operating. During the test run, keep fingers and
clothing away from any moving parts.
●
Clean up the site when finished, remembering to check that no metal scraps or bits of wiring have
been left behind inside the unit being installed.
After installation work for the system has been completed, explain the "Safety Precautions", the proper
use and maintenance of Central Station EX to the customer according to the information in all manuals
that came with the system. All manuals and warranty information must be given to the user or left near the
Indoor Unit.
