Take the following precautions to reduce the risk of property damage.
Ɣ Be careful that moisture, dust, or variant refrigerant compounds not enter the refrigerant cycle during
installation work. Foreign matter could damage internal components or cause blockages.

could run inside of the electrical box, possibly causing electrical failures.
Ɣ When installing the unit 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 the unit to malfunction. The operation of the unit
may also adversely affect these same devices. Install the unit at least 10 ft. (approximately 3m) away
from such devices.
Ɣ When a wireless controller is used, locate at a distance of at least 3.3 ft. (approximately 1m) between

operation commands.
Ɣ 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.
Ɣ Do not install the unit with any downward slope to the side of the drain boss. If you do, you may have

Ɣ Be sure the drain hose discharges water properly. If connected incorrectly, it may cause leaks.
Ɣ 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.
Ɣ If the wired controller is installed in a location where electromagnetic radiation is generated, make
sure that the wired controller is shielded and cables are sleeved inside conduit tubing.
Ɣ If there is a source of electrical interference near the power source, install noise suppression

within the operational temperature boundary of 35 to 104°F (0 to 40°C).
Ɣ Read installation and appropriate user manuals for connection with PC or peripheral devices. If a
warning window appears on the PC, the product stops, does not work properly or works intermittently,
immediately stop using the equipment.
