The Alarm
Low pressure fault
•
After the compressor running for 5 minutes, if the low-pressure switch is detected to
be in the off state for 10 consecutive seconds, the compressor immediately stops
running. At this time, the controller displays the low-pressure fault alarm code “04E”.
If the low-pressure switch is restored, error code does not occur.
•
If no other protection or locking occurs, the compressor is restarted after 3 minutes.
•
If low-pressure fault protection appears 3 times within 1 hour, the controller will lock
the protection and the compressor will lock in the shutdown protection state.
•
At this time, only the shutdown and restarting can unlock the compressor.
The low-pressure switch is not detected during the defrosting.
High pressure failure
•
After the compressor is started, if the high-pressure switch is detected to be in the off
state for 10 seconds, the compressor immediately stops running.
•
At this time, the controller displays the high-pressure fault alarm code “03E”. If the
high-pressure switch is restored, error code will not occur.
•
And if no other protection or locking occurs, the compressor is restarted after 3
minutes.
•
If high-pressure fault protection appears 3 times within 1 hour, the controller will lock
the protection, and the compressor will be locked in the shutdown protection state. At
this time, only the shutdown and restarting can unlock the compressor.
•
At this time, the electric heater is started to heat the water to 75
℃
and the water
temperature is maintained at 70 to 75
℃
for 30 minutes, then the sterilization mode
will be automatically exited.
•
After starting the manual sterilization function, press and hold the “M” + “
∧
” + “
∨
”
button for 5 seconds or more at the same time to exit the manual sterilization mode.
When the water temperature setting value is ≥75
℃
, the sterilization function is not
activated.
Automatic sterilization mode:
•
If the water temperature setting value is <75
℃
, the controller operation time
reaches 7 days, the controller enters the automatic sterilization mode.
•
Once the automatic sterilization mode exits, time begins from zero.When the ambient
temperature is ≥ 20
℃
, the electric heater is started at 1:00 am to start sterilization.
•
When the ambient temperature is <20
℃
, the electric heater is started at 15:00 pm to
start sterilization.
•
After the automatic sterilization function is activated, the sterilization symbol flashes.
At this time, the electric heater is started to heat the water to 75
℃
.
•
And the water temperature is maintained at 70 to 75
℃
for 30 minutes, then the
sterilization mode will be automatically exited.
•
When the water temperature setting value is ≥75
℃
, the sterilization function is not
activated.
