(l)
When you use a Permaswage union in the repair section, you must make allowance for swage growth. Tighten the repair section in position after installation of the Permaswage union.
(m)
When you replace a tube bend section, make sure you keep the minimum straight length specifications for all fittings (Fig. 812).
