TROUBLESHOOTING
(2)
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.
Airfl ow 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.
● During oil recovery operation, the airfl ow may stop for approximately
10 minutes. (See page 2)
● During Heating operation, the unit will temporarily stop operation (be-
tween 4 and 15 minutes) as the Automatic Defrosting mode operates.
(See page 2)
● The fan may operate at low speed during Dry operation or when the
unit is monitoring the room's temperature.
