14. Apply a liberal amount of thermal paste
around both epoxy joints to prevent heat from
damaging joint integrity.
15. Install a metal brazing shield between the
joints and the plastic liner.
16. Protect the freezer fl oor from molten solder
during brazing.
17. Angle torch so that the fl ame is directed away
