Operations and Performance
▼
Check before running
• Check whether the earth wire is cut or disconnected.
• Check whether the air filter 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 re-starting 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.
▼
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.
• When an outdoor unit using R32 refrigerant is combined,
in order to detect refrigerant leak, do not turn off the circuit
breaker even if air conditioner will not be operated for long
time.
▼
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.
▼
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 filter 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 discharge of the outdoor unit.
During heating
• The air filter is clogged with a large amount of dust.
• The air intake or discharge of the indoor unit is clogged.
