TROUBLESHOOTING
The temperature you require may exceed the
setting range of the unit.
A function or mode currently enabled may be
preventing the adjustment of the temperature.
The air inlets or outlets of the indoor or outdoor
unit may be obstructed.
The indoor ambient temperature may have
reached the set temperature.
Heating mode may have just been selected as
the operation mode.
The distance between the indoor unit and the
remote control may be too great.
The remote control may not be properly aligned
with the indoor unit's signal receiver.
There may be a fluorescent lamp in the room.
The indoor unit may be significantly interfered
by static pressure, unstable voltage, etc.
There may be objects obstructing the signal
from the remote control.
The remote control buttons may be inoperative
due to the Control Lock function being enabled.
The batteries of the remote control may be de-
pleted.
The dust filters may be dirty.
The set temperature may not be suitable for the
current outdoor conditions.
The air inlets or outlets of the indoor or outdoor
unit may be obstructed.
There may be heat sources present when at-
tempting to cool the room.
Doors or windows may have been left open in
the room.
Set the temperature between a minimum of 16 °C (61 °F) to a
maximum of 30 °C (86 °F).
Some functions (e.g. Energy-Saving, 8 °C Heating) and oper-
ation modes (e.g. Ventilation) does not allow the user to adjust
the set temperature. First, deactivate the function or change
operation mode, then adjust the set temperature.
Clear away any objects or furniture that could be blocking the
air inlet or outlet of either units.
When the room temperature reaches the set temperature, the
indoor unit stops blowing out cooled or heated air. No action is
required unless the temperature is not to your liking, in which
case, adjust the set temperature.
To prevent cold air from being blown into the room as Heating
mode is started, the indoor unit will delay blowing air for 1 to
5 minutes in order to preheat the air. Wait until the delay has
elapsed.
Get within range of the indoor unit so that the signal from the
remote control can be transmitted successfully.
Make sure to be facing the unit as much as possible when
pressing buttons on the remote control.
Turn off the fluorescent lamp and try again, or move closer to
the indoor unit.
Unplug the power cord, wait for about 3 minutes, reconnect the
power, then turn on the unit and try using the remote control.
Remove any possible obstructions between the remote control
and the indoor unit that could be blocking the signal.
Deactivate the Control Lock function.
Replace the depleted batteries with new one.
Check and and clean the dust filters.
Set the temperature to be higher or lower, depending in the
conditions.
Clear away any objects or furniture that could be blocking the
air inlet or outlet of either units.
Turn off or remove any heat sources that could be counteract-
ing the cooling efficiency of the unit.
Close doors and windows to prevent cooled or heated air from
escaping the room.
