10. Cover seams and joints in insulation with duct tape or other
suitable material to prevent water from entering the insulation.
Use duct tape to secure temperature sensor cord to outside of
the insulation in several places.
11. Protect the insulated pipe from the wind by burying it at least
three inches deep or covering it with earth. If this is not possible,
slide a larger plastic pipe, sometimes referred to as “Big 0" or
drawpipe, over the exposed sections of insulated pipe.
12. Plug the power cord directly into a three-prong grounded 120
volt GFCI protected outlet installed in accordance with local and
national electrical codes. Do not use an extension cord.
