● 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 floor or other objects underneath.
● Do not use this unit for any purposes other than the Cooling, Heating,

TROUBLESHOOTING
The following conditions are not breakdowns or op-
eration failures.
Doesn't operate immediately:
● If the unit is stopped and then immediately started again, the com-
pressor will not operate for about 3 minutes, in order to prevent fuse
blowouts.
● Whenever the electrical breaker is turned off then on again, the protec-
tion circuit will operate for about 3 minutes, preventing unit operation
during that period.
Airflow is weak or stops:
● When Heating operation is started, indoor unit's fan may temporarily
stop, to allow internal parts to warm up.
● During Heating operation, if the room temperature rises above the
thermostat setting, the outdoor unit will stop, and the indoor unit's fan
will stop. If you wish to warm the room further, set the thermostat for a
higher setting.
