General Troubleshooting

1. Fujitsu AC doesn’t operate immediately

Possible causes:

• If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes, in order to prevent fuse blowouts.
• Whenever the Power Supply Plug is disconnected and then reconnected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.

2. Fujitsu AC have noise

Possible causes:

• During operation and immediately after stopping the unit, the sound of water flowing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing).
• During operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front cover due to temperature changes.
• During Heating operation, a sizzling sound may be heard occasional. This sound is produced by the Automatic Defrosting operation

3. Fujitsu AC have smell

Possible cause:

• 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.

4. Mist or steam are emitted in Fujitsu AC

Possible causes:

• During Cooling or Dry 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.
• During Heating operation, the outdoor unit’s fan may stop, and steam may be seen rising from the unit. This is due to Automatic Defrosting operation.

5. Fujitsu AC airflow is weak or stops

Possible causes:

• When Heating operation is started, fan speed is temporarily very low, 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 will operate at very low fan speed. If you wish to warm the room further, set the thermostat for a higher setting.
• During Heating operation, the unit will temporarily stop operation (between 7 and 15 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, the OPERATION Indicator Lamp will flash.
• The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature.
• During SUPER QUIET operation, the fan will operate at very low speed.
• In the monitor AUTO operation, the fan will operate at very low speed.

6. Water is produced from Fujitsu AC outdoor unit

Possible cause:

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

7. Fujitsu AC doesn’t operate at all

Possible causes:

• Is the Power Supply Plug disconnected its outlet?
• Has there been a power failure?
• Has a fuse blown out, or a circuit breaker been tripped?
• Is the timer operating?

7. Fujitsu AC not cool

Possible causes:

• Is the Air Filter dirty?
• Air the air conditioner’s intake grille or outlet port blocked?
• Did you adjust the room temperature settings (thermostat) correctly?
• 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 computers inside the room, or are there too many people in the room?

7. Fujitsu AC operates differently from the Remote Controller’s setting

Possible causes:

• Are the Remote Controller’s batteries dead?
• Are the Remote Controller’s batteries loaded properly?

How to clean Fujitsu air conditioner intake grille?

2. Replace them by two new Air cleaning filters.

• Remove the old air cleaning filters in reverse order of their installation.
• Install in the same way as for installation of the air cleaning filter set.

3. Install the two Air filters and close the Intake Grille

In regard to the Fujitsu air conditioner air filter:

POLYPHENOL CATECHIN AIR CLEANING FILTER (one sheet)

• The Air Cleaning Filters are disposable filters. (They can not be washed and reused.)
• For storage of the Air Cleaning Filters, use the filters as soon as possible after the package has been opened. (The air cleaning effect decreases when the filters are left in the opened package)
• Generally, the filters should be exchanged about every three months.

Negative air ions deodorizing filter (one sheet) – light blue

• The filters should be exchanged about every three years so as to maintain the deodorizing effect.
• Filter frame is not a one-off product.

Maintenance of Deodorizing Filters

In order to maintain the deodorizing effect, please clean the filter in the follow way once three months.

1. Remove the deodorizing filter.
2. Clean with water and dry in the air.
3. Reinstall the deodorizing filter.

Fujitsu Air Conditioner Troubleshooting

In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the Power Supply Plug, and consult authorized service personnel. Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to disconnect the Power Supply Plug or turn off your circuit breaker to ensure that power is completely off.

Before requesting service, perform the following checks:

Symptom: Doesn’t operate immediately

Problem:

• If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes, in order to prevent fuse blowouts.
• Whenever the Power Supply Plug is disconnected and then re- connected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.

Symptom: Noise is heard

Problem:

• During operation and immediately after stopping the unit, the sound of water flowing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing).
• During operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front cover due to temperature changes.
• During Heating operation, a sizzling sound may be heard occasional. This sound is produced by the Automatic Defrosting operation.

Symptom: Smells

Problem: 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.

Symptom: Mist or steam are emitted

Problem:

• During Cooling or Dry 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.
• During Heating operation, the outdoor unit’s fan may stop, and steam may be seen rising from the unit. This is due to Automatic Defrosting operation.

Symptom: Airflow is weak or stops

Problem:

• When Heating operation is started, fan speed is temporarily very low, 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 will operate at very low fan speed. If you wish to warm the room further, set the thermostat for a higher setting.
• During Heating operation, the unit will temporarily stop opera- tion (between 7 and 15 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, the OPERATION Indicator Lamp will flash.
• The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature.
• During SUPER QUIET operation, the fan will operate at very low speed
• In the monitor AUTO operation, the fan will operate at very low speed.

Symptom: Water is produced from the outdoor unit

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

Symptom: The AIR CLEAN Indicator Lamp (green) will begin to slowly flash (as shown in the figure):

Problem: After approximately 400 hours of Air Cleaning Mode use, the AIR CLEAN Indicator Lamp will begin to flash slowly (as shown in the figure). When this occurs, please stop the system, remove the mains socket and carry out maintenance on the dust collecting unit’s air filter.

Symptom: The AIR CLEAN Indicator Lamp (green) will begin to flash quickly (as shown in the figure):

Problem: After approximately 500 hours of Air Cleaning Mode use, the AIR CLEAN Indicator Lamp will begin to flash quickly (as shown in the figure). At this point, Air Cleaning will stop functioning. Please stop the system, remove the mains socket and carry out maintenance on the dust collecting unit’s air filter.

Symptom: Doesn’t operate at all

Problem:

• Is the Power Supply Plug disconnected its outlet?
• Has there been a power failure?
• Has a fuse blown out, or a circuit breaker been tripped?
• Is the timer operating?

Symptom: Poor Cooling performance

Problem:

• Is the Air Filter dirty?
• Air the air conditioner’s intake grille or outlet port blocked?
• Did you adjust the room temperature settings (thermostat) cor- rectly?
• Is there a window or door open?
• In the case of Cooling operation, is a window allowing bright sun- light to enter? (Close the curtains.)
• In the case of Cooling operation, are there heating apparatus and computers inside the room, or are there too many people in the room?
