TROUBLESHOOTING
Symptom
NORMAL
The damper opens and
FUNCTION
closes automatically
Symptom
Doesn't operate at all:
CHECK ONCE
MORE
Poor performance:
The unit operates
differently from the Remote
Control Unit's setting:
If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp
(Fig. 3 6) and the TIMER Indicator Lamp (Fig. 3 7) flashes, immediately stop operation, and consult authorized service
personnel.
When the OPERATION Indicator Lamp (Fig.3 6) and the 10°C HEAT Indicator Lamp (Fig.3 8) flashes, the operation can be
maintained temporary by changing of air outlet selection switch to
STOP button.
(If the damper does not close automatically, close the damper manually and fix the position by an adhesive tape etc.) The unit
operates almost the same as upper air flow operation, however the indicator lamp flashes continuously if same symptom is
detected again. Therefore, consult an authorized service personnel for the complete functional repair.
