Information for multi system air conditioner (Outdoor unit: MXZ series)

Multi system air conditioner (Outdoor unit: MXZ series) can connect two or more indoor units with one outdoor unit. According to the capacity, two or more units can operate simultaneously.
- When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the operation later cannot operate, indicating an operation state in blinking.
In this case, please set all the indoor units to the same operation mode.
- There might be a case that the indoor unit, which is operating in (AUTO) mode. Cannot change over to the operating mode (COOL HEAT) and becomes a state of standby.
- When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max. about 15 minutes) to blow out the warm air.
- In the heating operation, though indoor unit that does not operate may get warm or the sound of refrigerant flowing may be heard, they are not malfunction. The reason is that the refrigerant continuously flows into it.

Automatic operation

• According to a set temperature, cooling operation starts if the room temperature is too hot and heating operation starts if the room temperature is too cold.
  During automatic operation, if the room temperature changes and remains 2^ , 4^ or more above the set temperature for 15 minutes, the air conditioner switches to cooling mode. In the same way, if the room temperature remains 2^ , 4^ or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.

Because the room temperature is automatically adjusted in order to maintain a fixed effective temperature, cooling operation is performed a few degrees warmer and heating operation is performed a few degrees cooler than the set room temperature once the temperature is reached (automatic energy-saving operation).

■ Indicates that the filter needs cleaning. Ask authorized people to clean the filter
- When resetting "FILTER" display - When the [FILTER] button is pressed two times successively after cleaning the filter, the display goes off and is reset.

Note:

• When two or more different types of indoor unit are controlled, the cleaning period differs with the type of filter. When the master unit cleaning period arrives, "FILTER" is displayed. When the filter display goes off, the cumulative time is reset.
• "FILTER" indicates the cleaning period when the air conditioner was used under general indoor air conditions by criteria time. Since the degree of dirtiness depends on the environmental conditions, clean the filter accordingly.
• The filter cleaning period cumulative time differs with the model.
• This indication is not available for wireless remote controller.

Cleaning the filters

• Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the filters against a solid object to knock off dirt and dust.
• If the filters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the filters to dry completely before putting them back into the unit.

Caution:

• Do not dry the filters in direct sunlight or by using a heat source, such as an electric heater: this may warp them.
• Do not wash the filters in hot water (above 50^ , 122^ ), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit without air filters can cause malfunction.

Caution:

• Before you start cleaning, stop operation and turn OFF the power supply.
• Indoor units are equipped with filters to remove the dust of sucked-in air. Clean the filters using the methods shown in the following sketches.

Filter removal

Caution:

• In removing the filter, precautions must be taken to protect your eyes from dust. Also, if you have to climb up on a stool to do the job, be careful not to fall.
• When the filter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result.

Having trouble?	Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well.	■ Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)■ Check the temperature adjustment and adjust the set temperature.■ Make sure that there is plenty of space around the outdoor unit. Is the indoor unit air intake or outlet blocked?■ Has a door or window been left open?
When heating operation starts, warm air does not blow from the indoor unit soon.	■ Warm air does not blow until the indoor unit has sufficiently warmed up.
During heating mode, the air conditioner stops before the set room temperature is reached.	■ When the outdoor temperature is low and the humidity is high, frost may form on the outdoor unit. If this occurs, the outdoor unit performs a defrosting operation. Normal operation should begin after approximately 10 minutes.
Airflow direction changes during operation or airflow direction cannot be set.	■ During cooling mode, the vanes automatically move to the horizontal (down) position after 1 hour when the down (horizontal) airflow direction is selected. This is to prevent water from forming and dripping from the vanes.■ During heating mode, the vanes automatically move to the horizontal airflow direction when the airflow temperature is low or during defrosting mode.
When the airflow direction is changed, the vanes always move up and down past the set position before finally stopping at the position.	■ When the airflow direction is changed, the vanes move to the set position after detecting the base position.
A flowing water sound or occasional hissing sound is heard.	■ These sounds can be heard when refrigerant is flowing in the air conditioner or when the refrigerant flow is changing.
A cracking or creaking sound is heard.	■ These sounds can be heard when parts rub against each due to expan-sion and contraction from temperature changes.
The room has an unpleasant odor.	■ The indoor unit draws in air that contains gases produced from the walls, carpeting, and furniture as well as odors trapped in clothing, and then blows this air back into the room.
A white mist or vapor is emitted from the indoor unit.	■ If the indoor temperature and the humidity are high, this condition may occur when operation starts.■ During defrosting mode, cool airflow may blow down and appear like a mist.
Water or vapor is emitted from the outdoor unit.	■ During cooling mode, water may form and drip from the cool pipes and joints.■ During heating mode, water may form and drip from the heat exchang-er.■ During defrosting mode, water on the heat exchanger evaporates and water vapor may be emitted.
The operation indicator does not appear in the remote controller display.	■ Turn on the power switch. "⑥" will appear in the remote controller dis-play.
"⑦" appears in the remote controller display.	■ During central control, "⑧" appears in the remote controller display and air conditioner operation cannot be started or stopped using the remote controller.
When restarting the air conditioner soon after stopping it, it does not oper-ate even though the ON/OFF button is pressed.	■ Wait approximately three minutes. (Operation has stopped to protect the air conditioner.)
Air conditioner operates without the ON/OFF button being pressed.	■ Is the on timer set?Press the ON/OFF button to stop operation.■ Is the air conditioner connected to a central remote controller?Consult the concerned people who control the air conditioner.■ Does "⑨" appear in the remote controller display?Consult the concerned people who control the air conditioner.■ Has the auto recovery feature from power failures been set?Press the ON/OFF button to stop operation.
Air conditioner stops without the ON/OFF button being pressed.	■ Is the off timer set?Press the ON/OFF button to restart operation.■ Is the air conditioner connected to a central remote controller?Consult the concerned people who control the air conditioner.■ Does "⑩" appear in the remote controller display?Consult the concerned people who control the air conditioner.
Remote controller timer operation cannot be set.	■ Are timer settings invalid?If the timer can be set, WEEKLY , SIMPLE , or AUTO OFF appears in the remote controller display.
"PLEASE WAIT" appears in the remote controller display.	■ The initial settings are being performed. Wait approximately 3 minutes.
An error code appears in the remote controller display.	■ The protection devices have operated to protect the air conditioner.■ Do not attempt to repair this equipment by yourself. Turn off the power switch immediately and consult your dealer. Be sure to provide the dealer with the model name and information that appeared in the remote controller display.
Draining water or motor rotation sound is heard.	■ When cooling operation stops, the drain pump operates and then stops. Wait approximately 3 minutes.

11. Trouble Shooting

Having trouble?	Here is the solution. (Unit is operating normally.)
Noise is louder than specifications.	■ The indoor operation sound level is affected by the acoustics of the particular room as shown in the following table and will be higher than the noise specification, which was measured in anechoic room.
		High sound absorbing rooms	Normal rooms	Low sound absorbing rooms
	Location examples	Broadcasting studio, music room, etc.	Reception room, hotel lobby, etc.	Office, hotel room
	Noise levels	3 to 7 dB	6 to 10 dB	9 to 13 dB
Nothing appears in the wireless remote controller display, the display is faint, or signals are not received by the indoor unit unless the remote controller is close.	■ The batteries are low. Replace the batteries and press the Reset button. ■ If nothing appears even after the batteries are replaced, make sure that the batteries are installed in the correct directions (+,-).
The operation lamp near the receiver for the wireless remote controller on the indoor unit is blinking.	■ The self diagnosis function has operated to protect the air conditioner. ■ Do not attempt to repair this equipment by yourself. Turn off the power switch immediately and consult your dealer. Be sure to provide the dealer with the model name.
