¥ 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 inverter work to increase compressor rpm to keep the
unitÕs heating capability from decreasing. If the unitÕs heating perfor-
mance 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
hightemperature
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 heating operation with the
(HI) f an speed or want to mak e 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.
¥ With the
(LOW) setting, the unitÕs heating capacity will vary with the operating conditions.
! "
¥ 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 progr ammed, the sleep timer tak es 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.
