ss
sMulti system air conditioner (Outdoor unit: MXZ series) can con-
ss
nect 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 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.

3.1. Cleaning the filters and the indoor unit
Cleaning the filter
• Clean the filter using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the filter against a solid object to knock off dirt and dust.
• If the filter is especially dirty, wash it in lukewarm water. Take care to
rinse off any detergent thoroughly and allow the filter to dry completely
before putting it back into the unit.
Caution:
• Do not dry the filter in direct sunlight or by using a heat source,
such as an electric heater: this may warp it.
• Do not wash the filter in hot water (above 50°C), as this may warp
them.
• Make sure that the air filter is always installed. Operating the unit
without air filter can cause malfunction.
Cleaning the indoor unit
• Wipe the outside of the unit with a clean, dry, soft cloth.
• Clean off any oil stains or finger marks using a neutral household deter-
gent (such as dishwashing liquid or laundry detergent).
Caution:
Never use gasoline, benzene, thinner, scouring powder or any type of
non-neutral detergent, as these substances may damage the unit’s
case.

4. Troubleshooting
Before you call out a repair man, check the following table to see whether there is a simple solution to your problem.
Problem
Unit does not cool or heat very well.
The airflow direction suddenly changes.
A white mist is expelled from the indoor
unit.
The air conditioner cannot be operated
for about 3 minutes when restarted.
Air does not blow out soon in the heating
operation.
The start and stop functions are not available just after restarting the unit.
The operation is stopped for about
10 minutes in the heating operation.
Solution
Clean the filter.
After one hour of cooling mode or drying
mode operation with the airflow in a
downward direction, the unit will automatically change to the “Horizontal airflow” mode.
When the unit is in the heating or defrosting mode, it will automatically change to
the “Horizontal airflow” mode.
This may occur just after the unit is turned
on when a high level of humidity is
present in the room.
This protects the air conditioner according to instructions from the microprocessor. Please wait.
Please wait as the air conditioner is preparing to blow out warm air.
Wait about three minutes (operation has
stopped to prevent damage to the air conditioner).
Defrosting of the outdoor unit is being
done (Defrosting operation).
Since this is completed in 10 minutes,
please wait. (When the external temperature is too low and humidity is too high,
frost is formed.)
The operation lamp of the wireless remote controller’s receiver is flashing.
Unit operates even if ON/OFF button has
not been pressed.
No indication of wireless remote controller, indication is dim, or signal transmission cannot reach remote controller sensor.
Problem
A self-diagnostic function is being performed to preserve the air conditioner.
* Do not attempt to make repairs your-
self. Turn the main switch off and contact the dealer from whom you bought
the air conditioner. Provide him or her
with the name of the unit and the
number of times the operation lamp of
the wireless remote controller’s receiver
flashes.
It occurs for the AUTO RESTART FUNCTION mode.
Press the ON/OFF button to stop operation.
The batteries have run out.
Replace the batteries with new ones (size
AAA), and then press the reset button.
Though both alkaline batteries and manganese batteries can be used, alkaline
batteries are recommended because their
service life is longer than that of manganese batteries.
* If indication is not detected even when
new batteries have been replaced,
check that the batteries have been installed properly.
Solution
If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the
nature of the problem. Do not try to fix the unit yourself.
In any of the following cases, turn off the main power switch and contact your local dealer for service:
• The operation lamp (on the main unit) flashes.
• The switches do not work properly.
• The circuit breaker trips frequently (or the fuse blows frequently).
• Water has accidentally been splashed into the unit.
• Water leaks from the unit.
• Something is accidentally dropped into the air-conditioner.
• An unusual noise is heard during operation.
The following do not indicate any malfunction:
Odours: smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit.
Sound of liquid flowing inside indoor unit: this can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit.
Ticking sound coming from indoor unit: this can occur when cooling or heating has just begun or has just stopped. It is caused by the indoor unit shrinking
or expanding slightly due to the change in temperature.
5. Installation, relocation and inspection
Installation place
Avoid installing the air conditioner in the following places.
• Where flammable gas could leak.
Inverter type
Radio
fluorescent lamp
To prevent picture
distortion or
noise, keep 1 m
or more apart.
Wall, etc.
Wellventilated dry
place
100 mm or more
TV
400 mm or more
Caution:
Do not install the unit where flammable gas could leak.
If gas leaks and collects around the unit, it may cause an explosion.
• Where there is much machine oil.
• Salty place such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where there is oil splashing or much oily smoke.
Warning:
If the air conditioner operates but does not cool or heat (depending
on model) the room, consult your dealer since there may be a refrigerant leak. Be sure to ask the service representative whether there is
refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and
comes into contact with the fire of a fan heater, space heater, stove,
etc., harmful substances will be generated.
To prevent the effect
of a fluorescent lamp,
keep it away as far
apart as possible.
