remove the tool and insert the tting. Ensure

the piping and ring seat against the shoulder

Important! Only perform the necessary number

You should feel some resistance as the tting

goes into the piping. If you do not feel any

resistance, the piping may be over expanded

and will require additional time to shrink over

the tting.
