when it happens, will result in back flow pressure and damage the pond
aeration.
8. In case of less air, please check the following:
1)Whether the voltage is normal.
2)Whether the distributor or the connecting piece is damaged, air-leaking
or sacked.
3)pond aeration location with poor ventilation will result in over-high
temperature
and less air volume.
9. Replace the filtration cotton, the packing cup and the valve block
regularly to maintain air volume and pressure.
10.In case of abnormal power, please check the following:
1) Whether the working voltage is beyond the specified range.
2) Whether there is damage or air leakage at the air tube connections.
3) Whether the valve block or the packing cup is damaged.
4) pond aeration location with poor ventilation will result in an over-high
temperature of the pond aeration and less air output.
11.In case of non-operation of the pond aeration, please check the
following:
1) Whether the power line is damaged, whether there is verdigris, whether
the connection becomes loose, or there is a power cut-off.
