Information for multi system air conditioner (Outdoor  
unit: MXZ series)  
sMulti system air conditioner (Outdoor unit: MXZ series) can con-  
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 opera-  
tion 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. Care and cleaning  
Caution:  
Always turn off the power, first on the remote controller and then  
the main switch, before cleaning or servicing the unit.  
When installing or removing the filter or the intake grille, do not  
stand on an unsteady surface.You may fall and injure yourself. Be  
also careful not to let dust fall into your eyes.  
Dirty or clogged filters block the airflow and reduce efficiency. Very dirty  
filters can damage the air-conditioner itself.

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 units

Though both alkaline batteries and man-  
ganese batteries can be used, alkaline  
batteries are recommended because their  
service life is longer than that of manga-  
nese batteries.  
* If indication is not detected even when  
new batteries have been replaced,  
check that the batteries have been in-  
stalled properly.  
Wait about three minutes (operation has  
stopped to prevent damage to the air con-  
ditioner).  
The start and stop functions are not avail-  
able just after restarting the unit.  
Defrosting of the outdoor unit is being  
done (Defrosting operation).  
The operation is stopped for about  
10 minutes in the heating operation.  
Since this is completed in 10 minutes,  
please wait.(When the external tempera-  
ture is too low and humidity is too high,  
frost is formed.)  
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  
fluorescent lamp  
Caution:  
Do not install the unit where flammable gas could leak.  
Wall, etc.  
If gas leaks and collects around the unit, it may cause an explosion.  
To prevent the effect  
of a fluorescent lamp,  
keep it away as far  
apart as possible.  
Well-  
ventilated dry  
place  
Where there is much machine oil.  
To prevent picture  
distortion or

Where there is oil splashing or much oily smoke.  
noise, keep 1 m  
or more apart.  
100 mm or more  
400 mm or more  
TV  
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 refrig-  
erant 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 nor-  
mally 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.

5. Installation, relocation and inspection  
Electrical work  
Provide an exclusive circuit for power supply of the air conditioner.  
Be sure to observe the breaker capacity.  
Warning:  
The customer should not install this unit. If the unit is installed incorrectly, fire, electric shock, injury due to a falling unit, water leakage, etc.  
may result.  
Do not connect using branched outlet or an extension cord, and do not attach many loads to one electric outlet.  
A fire or electric shock may result from poor contact, poor insulation, exceeding the permissible current, etc.  
Consult your dealer.  
Caution:  
Apply grounding  
Do not connect a grounding wire to a gas pipe, water pipe, lightning rod or ground wire of a telephone.  
If a grounding is incorrect, it may cause an electric shock.  
Install an earth leakage breaker depending on the place where the air conditioner is to be installed (humid place, etc.).  
If the earth leakage breaker is not installed, it may cause an electric shock.  
Inspection and maintenance  
When the air conditioner is used for several seasons, the capacity may be lowered due to dirt inside the unit.  
Depending upon the conditions of use, an odor may be generated or dirt, dust, etc. may prevent proper drainage.  
It is recommended to apply inspection and maintenance (charged) by a specialist in addition to normal maintenance. Consult your dealer.  
Also consider operation sound  
Do not put an object around the air outlet of the outdoor unit. It may cause lowering of capacity or increase operating sound.  
If abnormal sound is heard during operation, consult your dealer.  
Relocation  
When the air conditioner is to be removed or reinstalled because of rebuilding, moving, etc., special techniques and work are required.  
Warning:  
Repair or relocation should not be done by the customer.  
If this is done incorrectly, it may cause a fire, electric shock, injury by dropping of the unit, water leakage, etc. Consult your dealer.  
Disposal  
To dispose of this product, consult your dealer.  
If you have any question, consult your dealer.
