Warning !
The septum ring has a sharp edge and should be
treated with care whenever cleaning or
handling the instrument.
Periodically check for debris in the funnel and blockage of the inlet and outlet
ports. Remove any debris present and clean the meshes.
The water outlet on the underside of the funnel can be unscrewed allowing
the inlet mesh to be removed and cleaned.
If necessary, bucket surfaces can be cleaned using a mild detergent solution.
