Step 4: 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 4-1 to 4-12. Do not allow any slack to occur in the
gasket throughout this step. It must remain tight at all times.
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.
