Frequently Asked Questions - AUTG09LVLB FUJITSU

Why does the air conditioner not start immediately after turning it on?

The unit has a 3-minute protection delay to prevent compressor damage. Wait 3 minutes; it will start automatically.

How do I clean the air filter?

Open the intake grille, remove the filter, vacuum or wash with mild detergent and warm water, dry thoroughly in shade, then reinstall.

What is ECONOMY mode and how does it save energy?

ECONOMY mode adjusts the thermostat slightly (higher in cooling, lower in heating) to reduce power consumption by about 30% compared to normal operation.

How do I set the ON or OFF timer?

Press TIMER MODE to select OFF or ON timer, then use TIMER SET (+/-) to adjust the desired time. The display will flash; after 5 seconds the setting is saved.

What does the SLEEP timer do?

During heating, it gradually lowers the temperature by 1°C every 30 minutes (up to 4°C). During cooling/dry, it raises by 1°C every hour (up to 2°C). The unit turns off after the set time.

Why is the indoor unit blowing mist or steam?

During cooling or dry mode, moist room air rapidly cools and condenses into a fine mist. This is normal and disappears quickly.

How do I use the manual operation if the remote is lost?

Press the MANUAL AUTO button on the indoor unit for more than 3 seconds (but less than 10) to start in AUTO mode at 24°C. Press again to stop.

What does the flashing ECONOMY indicator lamp mean?

It indicates the air filter needs cleaning. Clean the filter and press the MANUAL AUTO button for 2 seconds or less on the indoor unit to reset.

Can I use multiple indoor units with one outdoor unit?

Yes, this indoor unit can be connected to a multi-type outdoor unit. However, simultaneous heating and cooling modes are not allowed; the first unit's mode determines the outdoor unit's operation.

Why does the heating stop occasionally and the OPERATION lamp flash?

The unit is performing automatic defrosting to remove frost from the outdoor coil. This takes 4-15 minutes, after which heating resumes automatically.

WARNING!

In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the power supply plug or turn off the circuit breaker, 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 Problem		See Page
NORMAL FUNCTION	Doesn't operate immediately:	● 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.	—
	Noise is heard:	● 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 panel due to temperature changes.	—
		*● During Heating operation, a sizzling sound may be heard occasionally. This sound is produced by the Automatic Defrosting operation.	15
	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 indoor unit.	—
	Mist or steam are emitted:	● 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 cool air emitted from the indoor unit, 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 the Automatic Defrosting operation.	15
	Airflow is weak or stops:	*● 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 to a higher setting.	—
		*● During Heating operation, the unit will temporarily stop operation (between 4 and 15 minutes) as the Automatic Defrosting mode operates. During the Automatic Defrosting operation, the OPERATION indicator lamp will flash.	15

\*Heating Performance

● This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating performance is being produced, we recommend you use this air conditioner in conjunction with another type of heating appliance.
- Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

\*When Indoor and Outdoor Temperature are High

- When both indoor and outdoor temperatures are high during use of the heating mode, the outdoor unit's fan may stop at times.

\*Microcomputer-controlled Automatic Defrosting

• When using the Heating mode under conditions of low outdoor temperature and high humidity, frost may form on the outdoor unit, resulting in reduced operating performance.
  In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for about 4 to 15 minutes).
  During Automatic Defrosting operation, the OPERATION indicator lamp will flash.
  ● After heating operation stops, if frost forms on the outdoor unit, the unit will start Automatic Defrosting operation. At this time, the outdoor unit will automatically stop after operating for a few minutes.

Low Ambient Cooling

- When the outdoor temperature drops, the outdoor unit's fans may switch to Low Speed, or one of the fans may stop intermittently.

Dual Remote Controllers (optional)

An additional remote controller can be added up to the maximum of 2 remote controllers. Either remote controller can control the air conditioner. However, the timer functions cannot be used at the secondary unit.

Group Control

1 remote controller can control up to 16 air conditioners. All of the air conditioners will be operated with the same settings. Group control cannot be used when using it by the multi type.

AUTO Restart

In Event of Power Interruption

● Should the power supply to the air conditioner be interrupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored.
● Should a power failure occur during TIMER operation, the timer will be reset and the unit will begin (or stop) operating under the new timer setting. In this event, the TIMER indicator lamp will flash.

- Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily disconnect the power supply plug, reconnect it, and then use the remote controller to resume operation.

Multi-type Air conditioner

This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units to be operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.

Simultaneous Use of Multiple Units

Instructions relating to inverter ( ^* ) are applicable only to "INVERTER MODEL".

• When using a multi-type air conditioner, the multiple indoor units can be operated simultaneously, but when 2 or more indoor units of the same group are operated simultaneously, the heating and cooling efficiency will be less than when a single indoor unit is used alone. Accordingly, when you wish to use more than 1 indoor unit for cooling at the same time, the use should be concentrated at night and other times when less output is required. In the same way, when multiple units are used simultaneously for heating, it is recommended that they be used in conjunction with other auxiliary space heaters, as required.
• Seasonal and outdoor temperature conditions, the structure of the rooms and the number of persons present may also result in differences of operating efficiency. We recommend that you try various operating patterns in order to confirm the level of heating and cooling output provided by your units, and use the units in the way that best matches your family's lifestyle.
• If you discover that 1 or more units delivers a low level of cooling or heating during simultaneous operation, we recommend that you stop simultaneous operation of the multiple units.
  Operation cannot be done in the following different operating modes.
  If the indoor unit is instructed to do an operating mode that

it cannot perform, the OPERATION indicator lamp on the indoor unit will flash (1 second on, 1 second off) and the unit will go into the standby mode.

Heating mode and cooling mode (or dry mode)

Heating mode and fan mode

Operation can be done in the following different operating modes.

Cooling mode and dry mode

The operating mode (heating mode or cooling (dry) mode) of the outdoor unit will be determined by the operating mode of the indoor unit that was operated first. If the indoor unit was started in fan mode, the operating mode of the outdoor unit will not be determined.

For example, if indoor unit (A) was started in fan mode and then indoor unit (B) was then operated in heating mode, indoor unit (A) would temporarily start operation in fan mode but when indoor unit (B) started operating in heating mode, the OPERATION indicator lamp for indoor unit (A) would begin to fl ash (1 second on, 1 second off) and it would go into standby mode. Indoor unit (B) would continue to operate in heating mode.

Notice

Instructions relating to heating (\*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).

* During use of the heating mode, the outdoor unit will occasionally commence the defrost operation for brief periods. During the defrosting operation, if the user sets the indoor unit for heating again, the defrosting mode will continue, and the heating operation will begin after completion of defrosting, with the result that some time may be required before warm air is emitted.

* During use of the heating mode, the top of the indoor unit may become warm, but this is due to the fact that coolant is circulated through the indoor unit even when it is stopped; it is not a malfunction.
