CHECK BEFORE AND AFTER «TROUBLESHOOTING»

(A)

 

Check power supply wiring.

     • Check the power supply wires are correctly connected.

(B)

 

Check power supply.

     • Check that voltage is in specified range (±10% of the rating).
     • Check that power is being supplied.

• WARNING: If the following troubleshooting must be done with power supplied, 
be careful not to touch any uninsulated live part that can cause ELECTRIC SHOCK.

A CIRCUIT BREAKER TRIPS OR FUSE BLOWS.

• When circuit breaker is set to ON, it trips in a few moments. Resetting is not possible.
• Measure insulation resistance. There is a possibility of ground fault.
  If resistance value is 1 Mohm or less, insulation is defective.

B CIRCUIT BREAKER TRIPS IN SEVERAL MINUTES AFTER TURNING AIR CONDITIONER ON.

1 • There is the possibility of short circuit.
