Verification method
Check the power supply.
Check the electrical
continuity with a tester
[fig. 1]

Check the power
supply.
Run with the FAN MO-
TOR disconnected.
Check the electrical
continuity with a tester.
Run with the FAN MO-
TOR disconnected.
Check the electrical
continuity with a tester.
Run with the FAN MOTOR
disconnected.
Check the electrical conti-
nuity with a tester.
Run with the PUMP
disconnected.
Check the electrical
continuity between the
REACTOR terminals
with a tester and the
resistance value (0.1
A 20°C).
Check the FAN MOTOR
voltage with a tester.
Check the PUMP volt-
age with a tester.

Troubleshooting
Make sure the power supply is
correct.
If the fuse CF1 has blown, replace
the MAIN PCB.
If the CF3 fuse has blown, replace
the MAIN PCB.
If the CF4 fuse has blown, replace
the MAIN PCB.
Replace the MAIN PCB.
If the fuse CF1 or 2 or 3 has blown,
replace the MAIN PCB.
If the CF4 fuse has blown, replace
the MAIN PCB.
Make sure the power supply
is correct.
If the same error code appears,
the MAIN PCB or the PUMP
must be replaced. If a different
error code appears, replace the
FAN MOTOR.
If the fuse CF6 has blown,
replace the fuse.
If the CF7 fuse has blown,
replace the fuse.
If the same error code appears,
the MAIN PCB or FAN MOTOR
must be replaced. If a different
error code appears, replace the
PUMP.
If there is no electrical continu-
ity on the REACTOR, replace it.
If the voltage is abnormal,
replace the MAIN PCB.
Replace the MAIN PCB.
Replace the INVERTER PCB.
