• Be sure to put the cable leads deep into the terminal
board and tighten up the screws. Poor contact can
cause overheating of fi re, or malfunction.
• Be sure to use a disconnect switch. Follow the local and

6 WIRE CHECK
Miswiring of connecting cable will be self-corrected by the
wire check operation.
(1) Turn the circuit breaker on.
(2) Check that all LED(LED1A, LED1B) on the display board are fl ashing
simultaneously.
If one or more of the LED is/are kept lit, check for mismatching terminal
markings ( , L1, L2, 2) and correct them.
(3) To start the wire check, press the WIRE CHECK button(SW2) for 5
seconds or more.
The operation lamp on the indoor unit will fl ash, and three BEEP will be
emitted.
All LED will fl ash rapidly.
(4) When wire check is completed normally, all LED will fl ash simultaneously
and the operation will stop. (Wire check time: 5 - 10 minutes)
When self-correction can not done, all LED will indicate triple fl ash for
eight times and the operation will stop. Check and correct following
points.
• Check all pipings are connected.
• Check the stop valves are open.
After correction, repeat the wire check again. If error is still detected, or other types
of LED signal should be indicated, please contact a service technician. (Refer to
wiring diagram attached inside the outdoor unit for self diagnosis signal.)
