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, 2 or more units can operate simultaneously.

• When you try to operate 2 or more indoor units with 1 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

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

When the [FILTER] button is pressed 2 times successively after

cleaning the fi lter, the display goes off and is reset.

Note:

● When 2 or more different types of indoor unit are controlled, the cleaning

period differs with the type of fi lter. When the master unit cleaning period
arrives, “FILTER” is displayed. When the fi lter display goes off, the cumu-
lative 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 accord-
ingly.

● The fi lter cleaning period cumulative time differs with the model.

● This indication is not available for wireless remote controller.

► Cleaning the fi lters

• Clean the fi lters using a vacuum cleaner. If you do not have a vacuum clean-
er, 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), 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.

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.

could be damaged.

• Household neutral detergent or alkalescent detergent (for washing dishes or
clothes)

Note:
If alkaline detergent is used for cleaning, the part made of aluminum could
discolor.

Note:
Make sure the fi lter element is removed when cleaning the oil fi lter.

1 If the fi lter is not so dirty. (If the fi lter is cleaned once a week (once per 100 oper-

ating hours).)
Wash the fi lter with water and above-mentioned detergent using a scrubbing brush
or brush, etc. (It is more effective to wash the fi lter with lukewarm water.)

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 airfl ow 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.

A cracking or creaking sound is heard.

The room has an unpleasant odor.

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 approxi-

mately 10 minutes.

■

During cooling mode, the vanes automatically move to the horizontal

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

tion 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 defrost-

ing 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 refrigerant is fl owing in the air condi-

tioner or when the refrigerant fl ow is changing.

■

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
