INFORMATION
▪ The heating capacity
temperature falls. If this happens, use another heating
device together with the unit. (When using together with
appliances that produce open fire, ventilate the room
constantly). Do not place appliances that produce open
fire in places exposed to the air flow from the unit or
under the unit.
▪ It takes some time to heat up the room from the time
the unit is started since the unit uses a hot-air
circulating system to heat the entire room.
▪ If the hot air rises to the ceiling, leaving the area above
the floor cold, we recommend that you use the
circulator (the indoor fan for circulating air). Contact
your dealer for details.

drops when the outside
(program dry operation).
For the following conditions, a micro computer controls the air flow
direction which may be different from the display.
Cooling
▪ When the room temperature is
lower than the set
temperature.
▪ 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.
The air flow direction can be adjusted in one of the following ways:
▪ The air flow flap itself adjusts its position.
▪ The air flow direction can be fixed by the user.
▪ Automatic and desired position
WARNING
Never touch the air outlet or the horizontal blades while the
swing flap is in operation. Fingers may become caught or
the unit may break down.
NOTICE
▪ The movable limit of the flap is changeable. Contact
your dealer for details. (only for double-flow, multi-flow,
corner, ceiling-suspended and wall-mounted).
▪ Avoid operating in the horizontal direction
cause dew or dust to settle on the ceiling or flap.
16 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. It
may cause deterioration in the effect or stop the operation.
▪ Turn off the main power supply switch to the unit when the unit is
not used for longer periods of time. If the switch is on, it 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
filters (see "17.1.1 To clean the air filter" on
▪ 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.
Heating
▪ When starting operation.
▪ When the room temperature is
higher than the
temperature.
▪ At defrost operation.
