Installation
Install an appropriately sized fused disconnect switch for field installed heat
tape when applying it to all exposed piping. A shore power 115V plug is
provided for factory installed heat tape. Be sure to use heat tape that is
recommended for low-temperature applications, it should be thermostatic
controlled and dissipate 7 watts per linear foot. A field installed thermostat
must be installed if the heat tape does not include a thermostat.
To install the heat tape properly, follow the instructions provided by the heat
tape manufacturer. If no instructions are provided, use the recommendations
outlined below:
1. Wrap the heat tape around the pipe or apply it straight along the pipe, as
necessary, to provide the required protection. Refer to Figure 15 and
Tables 2A and 2B.
2. Use friction tape to secure the heat tape to the solution pipe.
3. Place the thermostat parallel to the water pipe and tape it tightly in place
at both ends. Be sure to install the thermostat on the most exposed (i.e.,
coldest) portion of the pipe.
4. Wrap the pipe with an insulation material and cover it with a weatherproof
tape (if additional protection is required). On vertical pipe runs, start the
wrap at the bottom and work up as shown in Figure 15. Be sure to over-
lap the tape so that it will shed moisture.
Note: To prevent heat tape failure, frozen pipes, and other unit damage, do
not install insulation under the weatherproof wrap if a non-thermostatic
controlled heat tape is used.
