CAUTION
NEVER expose little children, plants or animals directly to
the airflow.
WARNING
Do NOT place objects below the indoor and/or outdoor unit
that may get wet. Otherwise condensation on the unit or
refrigerant pipes, air filter dirt or drain blockage may cause
dripping, and objects under the unit may get dirty or
damaged.
NOTICE
Do NOT use the system for other purposes. In order to
avoid any quality deterioration, do NOT use the unit for
cooling precision instruments, food, plants, animals, or
works of art.
CAUTION
Do NOT operate the system when using a room
fumigation-type insecticide. Chemicals could collect in the
unit, and endanger the health of people who are
hypersensitive to chemicals.
WARNING
Do NOT place a flammable spray bottle near the air
conditioner and do NOT use sprays. Doing so may result in
a fire.
Observe the following precautions to ensure the system operates
properly.
▪ Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.
▪ Ventilate often. Extended use requires special attention to
ventilation.
▪ Keep doors and windows closed. If the doors and windows remain
open, air will flow out of your room causing a decrease in the
cooling or heating effect.
▪ Be careful NOT to cool or heat too much. To save energy, keep
the temperature setting at a moderate level.
▪ NEVER place objects near the air inlet or the air outlet of the unit.
Doing so may cause a reduced heating/cooling effect or stop
operation.
▪ Turn off the main power supply switch to the unit when the unit is
NOT used for longer periods of time. If the main power supply
switch is on, the unit consumes electricity. Before restarting the
unit, turn on the main power supply switch 6 hours before
operation to ensure smooth running.
▪ Condensation may form if the humidity is above 80% or if the
drain outlet gets blocked.
▪ Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling. Notice that it
may take some time for the room temperature to reach the set
temperature. Consider using the timer setting options.
▪ Adjust the air flow direction to avoid cool air from gathering on the
floor or warm air against the ceiling. (Up during cooling or dry
operation to the ceiling and down during heating operation.)
▪ Avoid direct air flow to room inhabitants.
