OPERATING TIPS

Operation and Performance

About priority state and standby state

 

Multiple indoor units can be connected within the same system. De-
pending on the system, choice of operating mode are limited.

Cooling priority state:

When the other indoor units within the same system operate in cooling 
or dry mode, heating can not be selected at the same time.

Heating priority state:

When the other indoor units within the same system operate in heating 
mode, cooling and dry mode can not be selected at the same time.

Standby state:

The standby state activates when 2 or more indoor units start up at the 
same time in different mode. Any indoor unit other than priority mode 
will wait in standby state until priority mode changes (operation starts 
as soon as priority is switched).
At this time, the OPERATION indicator lamp (green) lights up and the 
TIMER indicator lamp (orange) 

fl

 ashes. (limited to only when receiver 

unit is connected)

Low ambient cooling

 

When the outdoor temperature drops, the outdoor unit’s fans may 
switch to Low Speed, or one of the fans may stop intermittently.

Heating performance

 

Heating mode operates on the heat-pump principle, absorbing heat 
from outdoor air and transferring that heat indoors. As a result, the 
operating performance is reduced as outdoor air temperature drops. 
If you feel that insuf

fi

 cient heating performance is being produced, we 

recommend you use this air conditioner in conjunction with another 
type of heating appliance.

 

Heating mode heat your entire room by recirculating air throughout the 
room, with the result that some time may be required after 

fi

 rst starting 

the air conditioner until the room is heated.

Microcomputer-controlled automatic defrosting

 

When using the Heating mode under conditions of low outdoor air 
temperature high humidity, frost may form on the outdoor unit, result-
ing in reduced operating performance. In order to prevent this kind of 
reduced performance, this unit is equipped with a Microcomputer-con-
trolled automatic defrosting function. If frost forms, the air conditioner 
will temporarily stop, and the defrosting circuit will operate brie

fl

 y (for 

about 4 to 15 minutes). 
During Automatic Defrosting operation, the OPERATION indicator 
lamp (green) will 

fl

 ash (limited to only when receiver unit is connected).

Oil recovery operation

 

Periodically, the oil recovery operation is performed in order to return 
compressor oil to the outdoor unit. 
During oil recovery operation, the OPERATION indicator lamp (green) 
will 

fl

 ash (for about 10 minutes) (limited to only when receiver unit is 

connected).

Temperature and humidity range

 

The temperature and humidity required for operating this product is as 
shown in the following table.

Cooling Mode

Heating Mode

Indoor unit inlet 
air temperature

18 to 43 °C DB

32 °C WB or less

-7 to 21 °C DB

Indoor unit inlet 
air humidity

90% or less

---

 

If the air conditioner is operated under higher temperature conditions 
than those listed, the built-in protection circuit may operate to prevent 
internal circuit damage. Also, during Cooling mode, if the unit is used 
under conditions of lower temperature than those listed above, the 
heat-exchanger may freeze, leading to water leakage and other dam-
age.

 

If the unit is used for long periods under high-humidity conditions, 
condensation may form on the surface of the indoor unit, and drip onto 
the 

fl

 oor or other objects underneath.

 

Do not use this unit for any purposes other than the Cooling, Heating, 
Dehumidifying, and air-circulation of rooms in ordinary dwellings.

CLEANING AND CARE

 CAUTION

 

Before cleaning the unit, be sure to stop the unit and disconnect the 
power supply.

 

Do not stand on an unstable platform when cleaning.

 

When removing and replacing the air 

fi

 lters, be sure not to touch the 

heat exchanger, as personal injury may result.

 

Do not clean the inside of the unit by yourself. To clean the inside, 
always consult authorized service personnel.

 

When cleaning the unit’s body, do not use water hotter than 40 °C, 
harsh abrasive cleansers, or volatile agents like benzene or thinner.

 

If dirt is allowed to accumulate on the air 

fi

 lter, air

fl

 ow will be reduced, 

lowering operating ef

fi

 ciency and increasing noise.

During periods of normal use, the air 

fi

 lters should be cleaned regularly.

Cleaning

Cleaning the Air 

fi

 lter

Remove dust with a vacuum cleaner or by washing. After washing, be 
sure to allow it to dry thoroughly in a shady place before reinstalling.

When not using for an extended period

Leave the breaker on for at least 12 hours before starting operation when 
it is to be used again.
