Small flange connections
Leakages are often due to improper small flange connections between the
various components and hose connections or to leakages in the valves.
• Loosen the connection and place the centring ring (with sealing ring
inside) in a centred manner between the flange connections.
• Seal the connection with the clamping ring by tightening the wing nut.
• Ensure that the centring ring neither slips out of place nor gets jammed.
