2 Indoor fan operates, but compressor does
not. See page 121
3 Cooling / heating operation starts but stops
immediately. See page 123
4 After shutting down, equipment does not
restart for a while. See page 124

10 Remote controller LCD displays “ 88 .” See page 131
11 Equipment emits odor. Room smell and cigarette odors
accumulated inside the indoor unit are
discharged with air. Inside of the indoor unit
must be cleaned.
12 Flap operates when power is turned on. It is normal. The flap initializes for accurate
positioning.
13 Change of operation mode causes flap to
move. It is normal. There is a control function that
moves the flap when operation mode is
changed.
14 Fan operates in “M” mode during heating
even if remote controller is set to “Low.” It is normal. It is caused by the activation of
the overload control (airflow shift control).
15 Flap automatically moves during cooling. It is normal. It is caused by the activation of
the dew prevention function or ceiling
soiling prevention function.
16 Indoor unit fan operates in “L” mode for 1
minute in microcomputer-controlled dry
mode even if compressor is not operating. It is normal. The monitoring function
forcibly operates the fan for one minute.
17 In simultaneous ON/OFF multi-system
setup, indoor unit (sub) does not operate in
sync with the other indoor unit (main).
(Flat, fan, etc.) It is normal. It is caused by a signal
transmission lag.
18 Indoor unit fan operates after heating
operation stops. It is normal. The fan operates in the “LL”
mode for 60 to 100 seconds to dissipate the
residual heat in the heater.
19 Drain pump operates when equipment is
not operating. It is normal. The drain pump continues to
operate for several minutes after
equipment is turned off.
20 Horizontal wing sends air to different
directions in cooling and heating even if it is
set to the same position. It is normal. The airflow direction in cooling/
dry operation is different from that in
heating/fan operation.
21 Flap remains horizontal even if it is set to
Swing. It is normal. The flap does not swing in the
thermostat OFF mode.
