Diagnosis
Countermeasure
Does the low
pressure fluctuate after the
startup?
Is the
connection of sensor connector
OK?
Does the
error occur immediately after
the startup?
Are the
sensor characteristics
OK?*
* The sensor
characteristics is shown in

Is the opening
degree of EEV
for evaporator side
flucturing?
Is the
connection of
thermistor connector for
heat exchanger
OK?
Is the checked
result of harness and insulation
of EEV coil OK?
Are the thermistor
characteristics OK?
Does the
EEV operate
normally by judging
from Mente PC
data, etc?
Isn’t EEV
or strainer
clogged?

Check and save the data of
operating conditions
Check error status.
Is the refrigerant amount
OK
Check additional
refrigerant amount charged
at site according to the
piping length instructed
on the label pasted on the
panel of the unit.
Check whether the service
valves are open.
Correct the connection
of low pressure sensor
connector
Replace low pressure
sensor.
Replace outdoor control
PCB.
Correct the connection of
temperature thermistor
connector of heat
exchanger
Replace temperature
thermistor of heat
exchanger at evaporator
side.
Replace control PCB at
evaporator side.
Replace EEV coil.
Replace EEV main body or
strainer.
Check for short circuit of
airflow of heat exchanger
at evaporator side and for
fan motor anomaly
2. Error detection method
Detection of anomalously low
pressure
3.
Condition of error displayed
• At start up after power on:
When the low pressure sensor
detects lower than 0.003MPa
for 60 seconds continuously.
And if this anomaly occurs 2
times.
•
During operation:
When the low pressure sensor
detects 0.134MPa or lower
for 30 seconds coninuously.
And if this anomaly occurs 5
times within 60 minutes
4. Presumable cause
•
Low pressure sensor (PSL)
anomaly
•
Service valves closed
•
EEV anomaly (EEV closed)
•
Insufficient refrigerant
amount
•
Clogging at EEV or strainer
Note:
Check whether the indoor unit is connected to other outdoor superlink network.
If the error does not recur, connect the Mente PC and continue to collect data.
