Compared with the sliding vane suction device, diaphragm suction device with low noise and stabilization. Because of its structure and circuit is relatively complex, failure rate and maintenance is corresponding to high.
a). Manual switch is normal, foot switch is unresponsive
The manual switch is normal, that the machine circuit can operate normally. The manual switch is normal, that the machine circuit can operate normally. www.hksuction.com
There are two reason: 1). broken circuit 2).Micro switch failure
In this case, we replace the large electric shock reed.
b). Negative suction is insufficient
This is more complicated. There are four general case.
1). Rubber aging pipeline break, leak or loose connections is not binding-------Replace the rubber tube, then firmly.
2).Operational fault:Two bottles must be used as required and marked with liquid level. However, in the course of use, some people only use one bottle, the body waste into the pump inlet, resulting in lack suction or even no suction-------Unplug the rubber tube, clean the filter, re-connect.
3).The air intake is blown outside.
Pump air inlet diaphragm is not close, Remove the pump, clean or replace the diaphragm.
