Before using for the first time
Rinse the tubular filter before first use under running water to remo‐
ve any possible external soiling.
Carry out a visual check to make sure there is no visible damage to
it. A damaged tubular filter must not be used.
The O rings at either end seal the tubular filter. The filter must not be
used without the O rings.
Check that the O rings are present and not damaged.
Carry out a visual check to make sure the injector tube is free of any
possible soiling inside it. If necessary rinse it through before inser‐
ting the tubular filter.
