What to do if the suction does not stop when the electrical appliance is switched off on my Renfert Silent V4 Medical Equipment?

If the suction on your Renfert Medical Equipment doesn't stop when the connected electrical appliance is switched off, it could be due to the following reasons: 1. The electrical appliance might not be connected to the QCB. Ensure it is properly connected. 2. The on/off threshold might be set too low. Adjust the on/off threshold accordingly. 3. A connected remote control might have priority over the QCB for that suction channel. Press the mouse scroll wheel from the relevant suction channel to give the QCB priority again.
