General Instructions
•Observe the safety warnings on page 1. Follow the installation steps (pages
•To ensure the plug is properly connected, do not assemble at temperatures below 0°F
•The Frostex system can be left plugged in all year, but you will save energy by unplugging the system when there is no risk of freezing.
•Use a properly grounded,
•In manufactured housing installations, use the electrical receptacle on the underside of the home. Do not use an extension cord or there may be danger of fire or shock.
Using an extension cord is not in compliance with national electrical codes.
•Frostex heating cable may be used on metal or plastic pipes and tubing. Do not install on garden hoses or in applications with tubing that is flexed frequently.
•Exposure to temperatures above 150°F (65°C) will shorten the life of your Frostex heating cable. Before installing the heating cable on hot water pipes, set the water heater ther- mostat below 150°F (65°C), low to medium on most ther- mostats.
•Remove any old heating tapes and insulation before you install the Frostex heating cable.
•Do not use more than 50 feet (15 meters) of Frostex heat- ing cable with each 9800 FlexFit plug. Longer lengths will blow the nonreplaceable fuse in the plug.
•The homeowner will need to keep these instructions for future reference. It contains important safety warnings and maintenance information.
•If you have any difficulty installing the system, please contact Tyco Thermal Controls for information at (800)
•Remove the clear label that covers the test and reset buttons after installation.
Installation Instructions
Step 1.
Determine the length of heat- ing cable you need.
1A. Collect the necessary information.
You will need to know the following:
•Type of pipe (plastic or metal).
•Length and diameter of pipe.
•Lowest expected air temperature (disregard windchill).
•Number of valves and spigots (requires additional heating cable).
•If there is a crock (typically used for manufactured housing applications).
1B. Determine the amount of Frostex heating cable you will need.
How to use the tables:
•Decide on the lowest temperature you can expect in your area, down to
•Measure the diameter of your pipe in inches.
•Using Table 1 or 2 depending on pipe material, determine how many straight runs of Frostex heating cable required to protect the pipe. One run is equal to the length of the pipe.
•To minimize the amount of heating cable required, select the optimal insulation thickness from Table 1 or Table 2.
