Step 5: Install Gasket Seal. Two people may be required
to perform this step.
The procedure below is a recommended process. Any suitable method for
achieving a snug inner ring is acceptable.
Follow Fig’s 5-1 to 5-12. Surfaces must be clean and dry. Clean away any
excess coupling compound. Do not allow any slack to occur in the gasket
throughout this step. It must remain tight at all times.
Gasket Must Remain
Clean and Free of Grease at all times. If the gasket should become
contaminated, remove and use acetone to clean.
The Idea here is to seal the exposed gap between the transducers
footprint and the pipe. Wrap the transducer footprint, twice, with the O-
ring gasket material provided, then tie to secure in place. The inner layer
performs the function of seal. The second outer layer protects and backs
up the first.
Install the Housing Covers and remove the spacer bar to complete this
procedure.
