1. Check that the power terminal of the fan is
tightened.
2. Check that the voltage of the DC power is
within the operating range.
3. Check that the fan is not stuck by foreign
matters.
4. Check the output status of the fan in the
cabinet.
4 The fan
generates
abnormal noise.
● The fan bearing
wears out.

is faulty.
● The compressor
motor is burned.
● There is no

o.
1. Secure cable connectors.
2. Check the main power switch.
3. Check that the voltage of the DC power is
within the operating range.
4. Replace the compressor.
5. Check the temperature inside the cabinet.
6. The delay interval for the compressor
startup is 3 minutes.
7. Check whether the contact of the
compressor protector is open.
8. Check whether the external ambient
temperature is too high, whether the air
volume of the external circulation fan is
insucient, and whether the contact of the
high pressure switch is open.
6 The cooling
eect is
unsatisfactory.
The air volume of
the external
circulation fan is
insucient.
Clean the foreign matter on the coil pipe or at
the air intake vent.
