BOLA Pressure-Relief Valve

5. Service / Maintenance

Rinse the pressure-relief valve with clear water after use. Connect the valve to a tap for rinsing. It is possible that the
adjusted opening pressure has to be reduced as it has to be lower than the water pressure in the water line. For cleaning
of the single components, please observe the following steps for correct disassembly:
» Loosen the locking nut (1). Remove the adjusting screw (2) from
the top section (4) by turning it counterclockwise.
» Remove the toggle (3) from the top section (4) by turning it
counterclockwise.
» Remove all four screws with a screw driver (blade with 3.5 mm) by
turning them counterclockwise.
