Assembly Steps
Roughen 1 cm square area on lower side of plastic container with sandpaper.
Figure 1.
Test Container Preparation
De-grease with alcohol.
Dry area with air gun.
Apply CYA glue to 1 cm square area.
Figure 2.
Applying CYA to Test Container
Attach transducer to glue spot with leads out to side of container.
Figure 3.
Mounting Transducer to Test Container
While applying gentle pressure to transducer to hold it in place apply “CYA Accelerator” to transducer.
Wait approximately 15 sec for glue to cure. Blow off excess Accelerator.
Apply alcohol to clean area. Dry area with air gun.
Apply hot glue around the circumference of the transducer.
Figure 4.
Applying Hot Glue to Transducer
Continue covering transducer until it is completely covered in hot glue.
Use air to gently cool glue.
