NOTE ON OPERATION

OPERATING CONDITION
temperature

Cooling

Upper limit
Heating
Lower limit
• The built-in protective device may prevent the
unit from operating when used at higher tem-
perature than this range.
• Condensation may form on the air outlet if the
unit operates continuously in the COOL or
DRY mode when humidity is over 80 %.
WHEN POWER FAILURE OCCURS
• This air conditioner has a memory function to
store settings when a power failure occurs.
After power recovery, the unit will automati-
cally re-start in the same settings which were
active before the power failure, except for
timer settings.
• If a power failure occurs while the timer is set,
the timer setting will be cancelled and will not
be retrieved even after the power is restored.
NOTE ON HEATING OPERATION
DEFROSTING FUNCTION
• When frost forms on the outdoor unit during
heating operation, the unit operate automatic
defrosting for about 5 to 10 minutes to remove
the frost. During defrosting, the inside and out-
side fans stop operating.
HEATING EFFICIENCY
• The unit employs a heat pump that draws
heat from the outside air and releases it into
the room. The outside temperature therefore
greatly affects the heating efficiency.
• If the heating efficiency is reduced due to
low outside temperatures, use an additional
heater.
• It takes time to warm up and heat the entire
room because of the forced air circulation sys-
tem.

TIPS ON SAVING ENERGY

Below are some simple ways to save en-
ergy when you use your air conditioner.
Set the proper temperature
• Setting to higher or lower then necessary tem-
perature point will result in increased power
consumption.
Block direct sunlight and prevent drafts
• Blocking direct sunlight during cooling opera-
tion will reduce power consumption.
• Close the windows and doors during cooling
and heating operations.
Keep filter clean to ensure the most ef-
ficient operation
Turn off the circuit breaker when the
unit is not used for an extended period
of time
• The indoor unit still consumes a small amount
of power when it is not operating.
