How to Respond
1 Check if power is supplied to air conditioner.
Nothing appears on the display unless power is
supplied.
2 Wait around 3 minutes to restart unit.
The air conditioner is in a state of being protected
by the microprocessor's directive. Once the com-
pressor is stopped, the unit cannot be restarted
for 3 minutes. This control is also applied when
the unit is turned on and off by remote controller.
3 Check code will be displayed if any protection
devices of the air conditioner are actuated.
What is check code?
1 Wait around 2 minutes.
An automatic startup test will be conducted for 2
minutes when power is supplied to the air con-
ditioner. "PLEASE WAIT" will be kept displayed
while that time.
2 This indicates that it is time to clean the air filters.
Clean the air filters. Press the FILTER button on
the remote controller twice to clear "FILTER" from
the display. See the operation manual that came
with the product for how to clean the filters.
3 This is displayed when the unit starts HEAT
operation, when the thermostat puts the compres-
sor in operation mode, or when the outdoor unit
ends DEFROST operation and returns to HEAT
operation. The display will automatically disappear
around 10 minutes later.
While "STANDBY" is displayed on the remote
controller, the airflow amount will be restricted
because the indoor unit's heat exchanger is not
fully heated up. In addition to that, the up/down
vane will be automatically set to horizontal blow
in order to prevent cold air from directly blowing
out to human body. The up/down vane will return
to the setting specified by the remote controller
when "STANDBY" is released.
4 The outdoor unit gets frosted when the outside
temperature is low and the humidity is high.
"DEFROST" indicates the DEFROST operation is
being performed to melt this frost. The DEFROST
operation ends in around 10 minutes (at most 15
minutes). During the DEFROST operation, the
indoor unit's heat exchanger becomes cold, so the
fan is stopped. The up/down vane will be auto-
matically set to horizontal blow in order to pre-
vent cold air from directly blowing out to human
body. The display will turn into "STANDBY" when
DEFROST operation ends.
