[4] HOW TO OPERATE THE OUTDOOR UNIT INDEPENDENTLY
1.Cooling in 40 Hz fixed mode
To operate the outdoor unit independently, short-circuit the sections indicated by arrows in the diagram below with an adapter, and apply 230 VAC
between (1) and (N) on the terminal board of the outdoor unit. This allows the outdoor unit to be operated in cooling mode independently.
(Do not operate the outdoor unit in this condition for an extended period of time.)

TH1, TH2, TH3, TH4, TH5
The errors for the thermistors that are not mentioned above are irrelevant.
These indoor units don’t have power relay.
1.Indoor unit does not turn on
Main cause
Inspection method
Normal value/condition
Remedy
Cracked PWB.
(Cracked pattern)
Check visually.
There should be no cracking in
PWB or pattern.
Replace PWB.
Open-circuit in FU1
(250 V, 3.15 A)
Check melting of FU1.
There should be no open-cir-
cuit.
Replace PWB.
2.Indoor unit fan does not operate
Main cause
Inspection method
Normal value/condition
Remedy
Open-circuit in heat exchanger
thermistor (TH2) (in heating opera-
tion)
Measure thermistor resistance
(dismount for check).
Refer to THERMISTOR TEM-
PERATURE CHARACTERIS-
TICS-1
Replace thermistor.
There should be no open-cir-
cuit or faulty contact.
Replace thermistor.
Disconnected heat exchanger therm-
istor (TH2) (in heating operation)
Inspect connector on PWB.
Check thermistor installation
condition.
Thermistor should not be dis-
connected.
Install correctly.
3.Indoor unit fan speed does not change
Main cause
Inspection method
Normal value/condition
Remedy
Remote control not designed to allow

except during dehumidifying
operation, ventilation, light de-
humidifying operation, internal-
ly normal operation
Explain to user.
4.Remote control signal is not received
Main cause
Inspection method

2.5 V or higher (two batteries in
series connection)
Install new batteries.
Batteries installed incorrectly.
Check battery direction.
As indicated on battery com-
partment.
