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 %.
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 indoor and out-
door 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 effi ciency.
• 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 system.
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.

With a multi system air conditioner, multiple in-
door units can connect to one outdoor unit.
Outdoor temperature
With a multi system air conditioner, you can not

operate different indoor units in different mode.
• If one unit is operating in COOL (or DRY)
14˚F (-10˚C)
mode, the other units are to be operated in
the same mode. The mode of the indoor unit
which operates fi rst is given priority. The in-
door unit turned on later in different mode can

not start operation. It starts to beep and the
OPERATION lamp and TIMER lamp starts to
75˚F (23.9˚C)
blink. In this case, set all the indoor units to
the same operation mode.
5˚F (-15˚C)
• COOL mode and DRY mode can be set at the
same time.
5˚F(-15˚C) AUTO STOP FUNCTION
• During the heating operation, the unit will
automatically stop when the outdoor tempera-
ture drops below 5°F(-15°C) to prevent the
outdoor unit from the damage caused by the
freezing of the drained water. The unit will
stop its operation for 4 hour and then resume
the operation when the outdoor temperature
rises above 7°F(-13.9°C).
• Outdoor temperature will be detected by the
thermometer incorporated in the unit. De-
tected temperature may differ from the actual
temperature depending on the installation
place and environment.
• The green OPERATION lamp and the red
5°F/-15°C AUTO OFF lamp will blink while the
unit stops.
• This function can be inactivated if you do not
want to use this function. Please contact your
contractor if you would like to inactivate this
function.
• Regardless of activating this function or not,
the lower limit of the operating condition for
cooling mode remains at 5°F (-15°C).
