Operations and performance
▼
Check before running
• Check whether the earth wire is cut or disconnected.
• Check whether the air
fi
lter is installed.
• Turn on the circuit breaker 12 hours or more before
starting operation.
▼
3 minutes protection function
3-minutes protection function prevents the
air conditioner from starting for initial 3 minutes after
the main power switch / circuit breaker is turned on for
restarting the air conditioner.
▼
Power failure
Power failure during operation will stop the unit
completely.
• To restart the operation, push the ON / OFF button
on the remote controller.
• Lightning or a wireless car telephone operating
nearby may cause the unit to malfunction. Turn off
the main power switch or circuit breaker and then
turn them on again. Push the ON / OFF button on the
remote controller to restart.
▼
Defrosting operation
If the outdoor unit is frosted during the heating
operation, defrosting starts automatically (for
approximately 2 to 10 minutes) to maintain the heating
capacity.
• The fans in both indoor and outdoor units will stop
during the defrosting operation.
• During the defrosting operation, the defrosted water
will be drained from the bottom plate of the
outdoor unit.
▼
Heating capacity
In the heating operation, the heat is absorbed from
the outside and brought into the room. This way of
heating is called heat pump system. When the outside
temperature is too low, it is recommended to use
another heating apparatus in combination with the
air conditioner.
▼
Protective device
• Stops operation when the air-conditioner is
overloaded.
• If the protective device is activated, the unit stops
running, and the operation indicator and check
indicator on the remote controller blink.
▼
If the protective device is activated
• Turn off the circuit breaker and perform a checkup.
Continued running may cause a malfunction.
• Check whether the air
fi
lter is installed. If not, the
heat exchanger may be clogged with dust and water
leakage may occur.
▼
During cooling
• The air intake or discharge of the outdoor unit is
clogged.
• Strong wind continuously blows against the outlet of
the outdoor unit.
▼
During heating
• The air
fi
lter is clogged with a large amount of dust.
• The air intake or discharge of the indoor unit is
clogged.
▼
Do not turn off the circuit breaker
• During the air-conditioning season, leave the circuit
breaker turned on, and use the ON / OFF key on the
remote controller.
▼
Attention to snowfall and freeze on the
outdoor unit
• In snowy areas, the air intake and air discharge
of the outdoor unit are often covered with snow or
frozen up. If snow or freeze on the outdoor unit is
left as it is, it may cause machine failure or poor
warming.
• In cold areas, pay attention to the drain hose so that
it perfectly drains water without water remaining
inside for freeze prevention. If water freezes in the
drain hose or inside the outdoor unit, it may cause
machine failure or poor warming.

Air conditioner operating conditions
For proper performance, operate the air conditioner under the following temperature conditions:
Cooling operation
Outdoor temperature
: –15°C to 46°C (Dry bulb temp.)
Room temperature
: 21°C to 32°C (Dry bulb temp.), 15°C to 24°C (Wet bulb temp.)
[CAUTION]
Room relative humidity – less than 80%. If the air conditioner operates in
excess of this
fi
gure, the surface of the air conditioner may cause dewing.
Heating operation
Outdoor temperature
: –15°C to 15°C (Wet bulb temp.)
Room temperature
