◆ Inspection of resistance value of discharge
pipe thermistor
Remove the connector and check the resistance value.
See the section of Thermistor characteristics on page 40.
◆Inspection of capacitor
Check the charging characteristics with a tester.
(Needle should swing and return slowy.Change
the polarity and check again.If the needle returns,
it is normal.)

¡ Check the voltage between terminals
1~2 on the terminal block. (It is
normal if AC220/240V is detected.)
¡ Fuse check:It is normal if it is con-
