Please refer to the exploded drawing of the MAS transducer in
Appendix A when using the following procedures. All cleaning of
the flow path can be accomplished with Freon™, alcohol, or any
cleaner safe for the listed materials.
Remove inlet and outlet fittings (Nos. 13), pull out the LFE hold-
downs (Nos. 12) and either replace or clean the inlet and outlet
screens (Nos. 14).

tapered shape with the larger diameter upstream (on the inlet
side). To remove the LFE for cleaning, simply push it out the inlet
side from the outlet side using a blunt object which does not mar
the flow channels. A
