BUBBLE TRAPPER CLEANING
Clean the Bubble Trapper. Remove the locking ring, then un-thread the Drainage Lid, so the sample
can be drained from the instrument. Wash it using neutral soap and dry it using a soft absorbent
paper, a type that will not leave residues. Make sure to look for areas where residues can
accumulate (shown below picture). Remove the Bubble trapper as shown below and after cleaning
make sure to put it back in place!
