A．General Information
How Heating Cable Work
The Problem
Thermal insulation alone will not prevent pipes from freezing. For example, a 19mm (0.75in) pipe having
25mm (1in) thick insulation will freeze solid in only 13 hours when the ambient temperature is at -10°C
(14°F). Frozen water pipes can burst causing loss of supply, flooding, and damage.
The Solution
An electric heating cable compensates the heat that is lost through the thermal insulation layer by keeping
the pipe and water inside the pipe at a constant temperature. With a built-in bi-metallic thermostat (inside
the black cap), the heating cable operates only when the thermostat is at a temperature of 4°C (40°F) or
below.
H eating Cable Application
The cable is mounted straight along the pipe and will protect pipes up to 3.8cm (1.5in) in diameter.
The electric heating cable is designed and approved for freeze protection of insulated metallic or plastic
general water piping at the generally accepted maintenance temperature of 4°C (40°F) with approved
accessories.
Warnings:
 Do not use on pipes heated above 65°C (150°F) such as steam lines.

Never install in walls, floors or ceiling.
 Never install on plastic pipe unless pipe is filled with water.
 Do not use on waste lines, drain lines, fuel lines or hoses.
 Do not us for roof and gutter de-icing applications.
