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. Accord ing 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 ﬂ owing may be heard, they are not malfunction. The reason is that the refrigerant continuously ﬂ ows 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 re-

mains 2 °C, 4 °F 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 °C, 4 °F or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.

Note:

When two or more different types of indoor unit are controlled, the clean-

ing period differs with the type of filter. When the master unit cleaning period arrives, “FILTER” is displayed. When the ﬁ lter 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 ﬁ lter accordingly.

The ﬁ lter cleaning period cumulative time differs with the model. This indication is not available for wireless remote controller.

FILTER

Filter removal

Caution:

• In removing the ﬁ lter, 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 ﬁ lter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result.

PLA-A

Cleaning the ﬁ lters

• Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the ﬁ lters against a solid object to knock off dirt and dust.

• If the ﬁ lters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the ﬁ lters to dry completely before putting them back into the unit.

Caution:

• Do not dry the ﬁ lters in direct sunlight or by using a heat source, such as an electric heater: this may warp them.

• Do not wash the ﬁ lters in hot water (above 50°C, 122°F), as this may warp them.

• Make sure that the air ﬁ lters are always installed. Operating the unit without air ﬁ lters can cause malfunction.

Caution:

• Before you start cleaning, stop operation and turn OFF the power supply.

• Indoor units are equipped with ﬁ lters to remove the dust of sucked-in air. Clean the ﬁ lters using the methods shown in the following sketches.

Pull the knob on the intake grille in the direction indicated by

the arrow and it should open. Open the intake grille. Release the knob on the center edge of the intake grille and

pull the ﬁ lter forward to remove the ﬁ lter.

11. Trouble Shooting

Having trouble? Here is the solution. (Unit is operating normally.)

Air conditioner does not heat or cool well.

When heating operation starts, warm air does not blow from the indoor unit soon.

Clean the ﬁ lter. (Airﬂ ow is reduced when the ﬁ lter 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? Warm air does not blow until the indoor unit has sufﬁ ciently warmed up.

During heating mode, the air conditioner stops before the set room temperature is reached.

Airﬂ ow direction changes during operation or airﬂ ow direction cannot be set.

When the airflow direction is changed, the vanes always move up and down past the set position before ﬁ nally stopping at the position.

A ﬂ owing water sound or occasional hissing sound is heard. These sounds can be heard when refrigerant is ﬂ owing in the air condi-

Air conditioner stops without the ON/OFF button being pressed.

Remote controller timer operation cannot be set. Are timer settings invalid?

“PLEASE WAIT” appears in the remote controller display. An error code appears in the remote controller display.

Draining water or motor rotation sound is heard. When cooling operation stops, the drain pump operates and then stops.

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.

During cooling mode, the vanes automatically move to the horizontal

(down) position after 1 hour when the down (horizontal) airﬂ ow 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

airﬂ ow direction when the airﬂ ow temperature is low or during defrosting mode.

When the airﬂ ow direction is changed, the vanes move to the set posi-

tion after detecting the base position.

These sounds can be heard when parts rub against each due to expan-

sion and contraction from temperature changes.

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.

If the indoor temperature and the humidity are high, this condition may

occur when operation starts.

During defrosting mode, cool airﬂ ow may blow down and appear like a

mist.

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.
