¥ This room air conditioner utilizes a heat pump system that absorbs
exterior heat and brings it into a room to be heated. As the ambient
temperature gets lower, heating capability will also lower. In such a
situation, the PAM and inverter work to increase compressor rpm to keep
the unitÕs heating capability from decreasing. If the unitÕs heating
performance is still unsatisfactory, other heating appliances should be
used to augment this unitÕs performance.
¥ The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer
operation is recommended for effective preheating ahead of the desired time.
¥Ifthe heat present in a room exceeds the unitÕs cooling capacity (for example, if there are many people in the room
or other heating appliances are used), the preset room temperature may not be reached.
"
Do not use a stove
or any other high-
temperature devices
in proximity to the
indoor unit.
¥ When fan speed, room temperature are set with the remote controller before starting manual operation and
the buttons are released, the indication of settings will go off in 10 seconds and only the operation mode will
be displayed.
¥Pressing the
button while the unit is in operation will let the protective circuit work so that the unit will not
operate for approximately 3 minutes.
¥ During heating operation, the indoor unitÕs color indicator lamp may flash with no air emitted for a while.
¥Ifyou feel cold wind during warming operation with the
(HI) fan speed or want to make the unit operation
quieter after the room is heated, use of
(AUTO) setting is recommended.
¥ With the
(LOW) setting, the unitÕs cooling capability will lower slightly.
¥ When the timer has been programmed, the unit will not operate even if the set time is reached unless the unit
receives a signal from the remote controller. Confirm that timer programming is complete (beep) and the
TIMER lamp of the indoor unit lights.
¥Ifthe
(SLEEP) button is pressed while the ON/OFF timer is programmed, the sleep timer takes priority.
¥ During sleep timer operation, the fan speed sets to
(LOW) regardless of the preset speed. The remote
controller display indication will remain unchanged even with the
(LOW) setting.

The following phenomena do not indicate unit failure.
<Operation start>
The unit is preparing to blow warm air. Please wait.
<In operation>
The outdoor unit is defrosting. Please wait.
Hissing or fizzy sounds
Refrigerant flow noise in the pipe or valve sound generated when flow rate is
adjusted.
Squeaking noise
Noise generated when the unit expands or contracts due to temperature
changes.
Rustling noise
Noise generated with the indoor unit fanÕs rpm changing such as operation start
times.
Clicking noise Noise of the motorized valve when the unit is switched on.
Perking noise
Noise of the ventilation fan sucking in air present in the drain hose and blowing out
dehumidifying water that had accumulated in the condensed water collector. For
details, consult your sales agent.
Changing operation noise
Operation noise changes due to power variations according to room temperature
changes.
Mist emission Mist is generated as the air within the room is suddenly cooled by conditioned air.
Duringheating, theoperationindicator
blinks and air blow stops
If the remote controller is not
transmitting a signal.
