3.3.3.1 Assembly clearances
Maintain adequate assembly clearances to ensure there is enough room to exchange the
gas flow meter. The upward clearance is needed to remove the gas flow meter from the
adapter and to put it back on again. The downward clearance is needed to loosen the
screws, take these out or insert these again and to fit the tool correctly.
