▪ When operating continuously at horizontal air flow direction.
▪ When continuous operation with downward air flow is performed
at the time of cooling with a ceiling-suspended or a wall-mounted
unit, the micro computer may control the flow direction, and then
the user interface indication will also change.

Energy saving and optimum
operation
Observe the following precautions to ensure the system operates
properly.
▪ Adjust the air outlet properly and avoid direct air flow to room
inhabitants.
▪ Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.
▪ 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.
▪ When the display shows
(time to clean the air filter), clean the
filters (see
"17.2.1 To clean the air filter"
▪ Keep the indoor unit and user interface at least 1 m away from
televisions, radios, stereos, and other similar equipment. Failing to
do so may cause static or distorted pictures.
▪ Do NOT place items under the indoor unit, as they may be
damaged by water.
▪ Condensation may form if the humidity is above 80% or if the
drain outlet gets blocked.
