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).
Temperature and humidity range
●
The temperature and humidity required for operating this product is as
shown in the following table.
Cooling/Dry Mode
Heating Mode
Outdoor
temperature
Please refer to the speci
fi
cation of outdoor units.
Indoor
temperature
18 to 32 °C DB
10 to 30 °C DB
Indoor humidity
About 80% 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 and Dry modes, 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
damage.
●
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.
●
Be sure the intake grille is installed securely.
●
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.
●
Do not remove any part from the unit except for the
fi
lter.
●
If dirt is allowed to accumulate on the Air Filter, 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 every 2
months.
Cleaning the Air Filter
When the
fi
lter lamp lights on, remove and clean the
fi
lter.
1. Push the intake grille push-buttons (two places)
and open the intake grille.
2. Pull out the
fi
lter from the intake grille.

Situations in which the sensor will detect no people in the room,
even when there is someone there
●
When the temperature is high and the difference with between people’s
body temperature is small. (Such as during the summer when the
temperature is 30°C or higher.)
●
When there is someone in the room, but they do not move for a long
period of time.
●
When someone is hidden behind a sofa, other furniture, glass, or in
similar situations.
●
When someone is wearing extremely thick clothing and has their back
facing the sensor.
Situations in which the sensor will incorrectly detect people in the
room, even when there is no one there
●
When there is a dog or a cat moving around in the room.
●
When the wind is making curtains or plants move.
●
When there are heating units, humidi
fi
ers, or electric appliances such
as oscillating electric fans operating.
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.
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.
