Check and save the data of
operating condition
Check the ROM version
Confirmation of SV1 operation
Propose an improvement to
the customer.
Adjust the refrigerant
amount poperly
(Check whether the
refrigerant amount is
insufficient or not.)
(Check the gas leakage)
Insert connectors securely.
Check if characteristics
are correct, referring to
the characteristics list of
E39. (Page 350) . And
if necessary, replace the
discharge pipe temperature
thermistor.
Check it, as much as
possible, under the
operating conditions for
30 minutes before error
occurred.
Wait and see.
Continue to obtain data, if
possible.
(Keep connecting the
Mente PC)
Check refrigerant amount
again.
2. Error detection method
Detection of anomalously high
temperature by the discharge
pipe temperature thermistor
3
.
Condition of error displayed
When the discharge pipe
temperature thermistor detects
115°C or higher the compressor
stops. After 3-minutes delay,
the compressor starts again
automatically, but if this
anomaly occurs 5 times within
60 minutes after the initial
detection.
4. Presumable cause
• Defective discharge pipe
temperature thermistor
• Defective outdoor control
PCB
• Insufficient amount of
refrigerant
• Insufficient airflow volume
• Short-circuit
