General Installation Notes
Read and observe the instructions in this guide
to insure that the HWAT System is installed
successfully.
• Accidental damage to the system can be minimized
during construction by installing thermal insulation
on the pipe immediately after the pipe has been
traced and the heating cable has been tested.
• Read all installation documentation to familiarize
yourself with the system components.
• Read and follow all warnings and recommenda-
tions. All involved trades should review this entire
guide and assess the recommendations applicable
to their scope of work.
• All heat-traced pipes and equipment must be ther-
mally insulated. Insulation is an important part
of the HWAT System. For an effective system, the
fiberglass insulation must be a specific thickness
for each specific pipe size as detailed in Table 2 on
page 17.
• Do not install the HWAT System below the mini-
mum installation temperature.
– The minimum installation temperature for HWAT
heating cables is 0°F (–18°C)
– The minimum installation temperature for HWAT-
ECO is 40°F (5°C).
• Ensure that your water heater temperature is set
at your desired pipe maintain temperature.
• Do not energize cable when it is coiled or on the
reel.
• Never use metal tie wire or pipe straps to secure
heating cables to pipes.
Important: Exceeding 185°F (85°C) for HWAT-R2
will decrease the power output of the heating cables
over time.
