• Do not put any foreign materials within the air inlet grille
operation range. It may lead to injury or damage.
• Keep the wire from fire or sharp edge. Breaking wire may cause
of injury due to air inlet grille or air filter falling.
• If the air inlet grille or the air filter falls, it may cause injury.
1 After completing installation of the air panel, Test Run should
be performed according to installation and maintenance
manual for the indoor unit.
2 Perform the checking work for the louver during the test run.
Do not move the louver by hand. If moved, the auto-swing
mechanism will be damaged.

• All electrical installation work must be performed by certified
personnel and all work must be complete and conform to local and
NEC (National Electrical Code) standards. Failure to uphold these
standards can result in damage, fire, electrical shock, and serious or
fatal injury.
• When opening and closing the electrical box cover, work so that it
does not contact the suspension wire. If the suspension wire breaks,
the air inlet grille and air filter may fall. It may cause injury.
• Perform securely the electrical wiring work. If the electrical work is not
completed, heat generation at the connection, a fire or an electrical
shock may occur.
• Make sure that the wires are securely fixed in order not to apply an
external force to the terminal connections of the wirings. If fixing is not
completed, heat generation or a fire will occur.
1 The air panel has motor wiring for auto louver. Remove the
tape securing the wiring and make sure to pass it through
the cable band as shown in the figure on the right before
connecting it to the connector (CN17) on the PCB.
2 After connecting the connector, tighten the cable band
to secure the wiring. After wiring is secured, attach the
electrical box cover.
3 The following connectors are used in the air panel. Remove
the tape fixing the wiring connectors on the air panel and pull
out them as shown in the figure below.
4 Connect them with the wiring connectors to CN17 in the
electrical box as the following figure.

installation practices which include positioning of office equipment,
room structure, and office cubicle or furniture layout. Adjust airflow
for maximum comfort.
• The position of the louvers may not coincide with the louver position
indicator on the LCD during auto swing operation. When adjusting
the louver angle, set it according to the louver position on the LCD.
• Even if the " " or " " are pressed to stop the auto swing function, the
louver is not stopped immediately.
• If the cooling operation is performed with greater than 80% relative
humidity, condensation may form on the air panel or louver surfaces.
