Add additional insulation if necessary. Mark all pipes at the point where the insulation jacket ends. Remove the jacket. Install field provided insulation on the run-out and main trunk pipes first. Peel the adhesive glue protector slip from the insulation jacket and install the clam-shell jacket over the fitting.
