Interested party Verification method
Incorrect connections
(PCB TERMINAL BLOCK Check connections.
- SMART-MT)
Ground cable -------
Anomaly differs from
TERMINAL BLOCK PCB the cases described
above.
Anomaly differs from
SMART-MT the cases described
above.
Check the correct con-
Power supply line nection of the neutral
(N)
Check the correct con-
Power supply line nection of the phases
(L1, L2, L3)
TEMP. SENSOR OUT- Check the resistance
BOUND WATER with a tester [tables].
TEMP. SENSOR IN- Check the resistance
COMING WATER with a tester [tables].
Check the
TEMP. SENSOR PLATE
resistance with
EXCHANGER
a tester [tables].
Check the INSTAL-
Recycling of LATION site (suction
outgoing air obstruction and
air outlet).
Check the difference
between water inlet
Obstruction in the
and outlet.
PUMP or hydraulic
A high difference
circuit
means that the flow
rate is too low.
PUMP or MAIN PCB
Check the PUMP volt-
age [fig. 3].
MAIN PCB
Check the difference
between water inlet
Obstruction in the
and outlet.
PUMP or hydraulic
A high difference
circuit
means that the flow
rate is too low.
Check the electrical
Fuse CF5
continuity of the CF5
(250V T3.15A)
fuse with a tester
Check wiring con-
HIGH PRESSURE
nection and incorrect
SWITCH
contact.
COMPRESSOR OVER- Check the resistance
TEMPERATURE RELAY with a tester
Check the service
Gas leakage valve and refrigeration
circuit.

Troubleshooting
Check the wiring connection and
incorrect contact, then restart
the device.
Check the correct INSTALLATION
of the ground wire.
Replace the TERMINAL BLOCK
PCB.
Replace SMART-MT.
Connect the neutral (N) correctly.
Connect the phases correctly
(L1, L2, L3).
Replace sensor if faulty.
Replace sensor if faulty.
Replace sensor if faulty.
Correct the INSTALLATION posi-
tion to avoid obstruction of air
intake and outlet.
Remove obstruction
and resume operation.
If the voltage is normal, replace
the PUMP.
If the tension is abnormal,
replace the MAIN PCB board.
Remove the obstruction and
resume operation.
Replace the CF5 FUSE
if blown.
If the same error code occurs
again, replace the
HIGH PRESSURE SWITCH.
Replace the OVERTEMPERA-
TURE
RELAY'
if tripped
Recover the refrigerant, then
recharge the prescribed mass.
Replace the MAIN PCB
