TROUBLESHOOTING

The following conditions are not breakdowns or op-
eration failures.

Doesn’t operate immediately:

 

If the unit is stopped and then immediately started again, the com-
pressor will not operate for about 3 minutes, in order to prevent fuse 
blowouts.

 

Whenever the electrical breaker is turned off then on again, the protec-
tion circuit will operate for about 3 minutes, preventing unit operation 
during that period.

Air

fl

 ow is weak or stops:

 

When Heating operation is started, indoor unit’s fan may temporarily 
stop, to allow internal parts to warm up.

 

During Heating operation, if the room temperature rises above the 
thermostat setting, the outdoor unit will stop, and the indoor unit’s fan 
will stop. If you wish to warm the room further, set the thermostat for a 
higher setting.

 

During oil recovery operation, the air

fl

 ow may stop for approximately 

10 minutes. (See page 2)

 

During Heating operation, the unit will temporarily stop operation (be-
tween 4 and 15 minutes) as the Automatic Defrosting mode operates. 
(See page 2)

 

The fan may operate at low speed during Dry operation or when the 
unit is monitoring the room’s temperature.

 

In the monitor AUTO operation, the fan will operate at low speed.

Flashing lamps:
(Limited to only when receiver unit is connected)

 

The OPERATION indicator lamp (green) 

fl

 ashes:

An oil recovery operation is being performed. (See page 2)

 

The OPERATION indicator lamp (green) 

fl

 ashes:

An automatic defrosting operation is being performed. (See page 2)

 

The OPERATION indicator lamp (green) and TIMER indicator lamp 
(orange) are 

fl

 ashing alternately:

It has recovered from a power outage.

 

The OPERATION indicator lamp (green) and TIMER indicator lamp 
(orange) are 

fl

 ashing simultaneously:

It is operating in trial operation mode. Ask a manager as there may be 
maintenance being conducted.

 

The OPERATION indicator lamp (green) lights up and the TIMER 
indicator lamp (orange) 

fl

 ashes:

This is the standby state. (See page 2)

Noise is heard:

 

In the following conditions there are sounds of water 

fl

 owing from the 

indoor unit and the operation sound becomes loud. These are the 
sounds of the 

fl

 owing of refrigerant.

When operation starts
When oil recovery operation 

fi

 nishes

When automatic defrosting operation 

fi

 nishes

 

During operation, a slight squeaking sound may be heard. This is the 
result of minute expansion and contraction of the panel due to tem-
perature changes.

 

During Heating operation, a sizzling sound may be heard occasionally. 
This sound is produced by the Automatic Defrosting operation. (See 
page 2)

Smells:

 

Some smell may be emitted from the indoor unit. This smell is the 
result of room smells (furniture, tobacco, etc.) which have been taken 
into the air conditioner.

Fog comes out of the indoor unit:

 

During Cooling operation, a thin mist may be seen emitted from the 
indoor unit. This results from the sudden Cooling of room air by the air 
emitted from the air conditioner, resulting in condensation and misting.

Steam comes out of the indoor unit:

 

During Heating operation, the outdoor unit’s fan may stop, and steam 
may be seen rising from the unit. This is due to the Automatic Defrost-
ing operation. (See page 2)

Water is produced from the outdoor unit:

 

During Heating operation, water may be produced from the outdoor 
unit due to the Automatic Defrosting operation.

The following conditions may not be breakdowns so 
check again.

Doesn’t operate at all:

 

Has there been a power failure?

 

Has a fuse blown out, or a circuit breaker been tripped?

 

Is the main power switch set to the OFF position?

 

Are you trying to engage in an operation different from the priority 
state? (See page 2)

 

Is it in standby state? (See page 2)

The operation mode cannot be changed:

 

Are you trying to change to an operation different from the priority 
conditions? (See page 2)

Poor Cooling (or Heating) performance:

 

Did you adjust the room temperature settings (thermostat) correctly?

 

Is the air 

fi

 lter dirty? (See page 2)

 

Are the air conditioner’s inlet port or outlet port blocked?

 

Is there a window or door open?

 

In the case of Cooling operation, is a window allowing bright sunlight to 
enter? (Close the curtains.)

 

In the case of Cooling operation, are there heating apparatus and com-
puters inside the room, or are there too many people in the room?

 

Is the fan speed set to low?

Set the temperature lower than the room temperature and use it:

 

Temperature does not fall down well.
Temperature may not fall down depending on the room conditions.
(While high humidity or the room temperature is high.) (See page 2)

In the following situations stop operation immediately 
and get in touch with authorized service personnel.

 

The problem cannot be solved even when the troubleshooting checks 
have been performed.

 

The FILTER indicator lamp (red) is 

fl

 ashing very fast (when receiver 

unit is connected).

 

The wired remote controller or simple remote controller indicate Er 
(when connected).

 

It has burning smell.

 

For details on marking the Flashing lamps, please refer to the Manual 
of “IR Receiver Unit” or “Wired Remote Controller”.
