Installation on Fittings and Equipment . . .
1. Install heating cable in accordance with illustrations below.
Secure heating cable to piping using attachment tape.
2. Elbows: Locate the cable on the outside radius of an elbow
to provide sufficient heat to compensate for the added pip-
ing material. Secure the cable to the pipe on each side of
the elbow with attachment tape.
