Take the following precautions to reduce the risk of property damage.
●
Prevent moisture, dust, or non condensable compounds from entering the refrigerant cycle during
installation work. Foreign matter could damage internal components or cause blockages.
●
If air filters are required on this unit, do not operate the unit without the air filter set in place. If the air
filter is not installed, dust may accumulate and breakdown may result.
●
Do not install this unit in any place where silicon gases can collect. If the silicon gas molecules attach
themselves to the surface of the heat exchanger, the finned surfaces will repel water. As a result, any
amount of drainage moisture condensate can overflow from the drain condensate pan and could run
inside of the electrical box, possibly causing electrical failures.
●
When installing the unit in a hospital or other facility where electromagnetic waves are generated
from nearby medical and/or electronic devices, be aware of noise and electronic interference
Electromagnetic Interference (EMI). Do not install where EMI 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.
●
When a wireless controller is used, locate at a distance of at least 3.3 ft. (approximately 1m) 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 with any downward slope to the side of the drain adapter. If you do, you may
have condensate flowing back which may cause leaks.
●
Be sure the condensate hose discharges water properly. If connected incorrectly, it may cause leaks.
●
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 ventilation unit 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.
●
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.
●
If there is a source of electrical interference near the power supply, install noise suppression
equipment (filter).
●
During the test run, check the unit’s operation temperature. If the unit is used in an environment
where the temperature exceeds the operation boundary, it may cause severe damage. Check the
operational temperature boundary in the manual. If there is no specified temperature, use the unit
within the operational temperature boundary of 32 to 104°F (0 to 40°C).
●
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.
