3.1
Heating Cable Storage
• Store the heating cable in a clean, dry location.
Temperature range: 0°F (–18°C) to 140°F (60°C).
• Protect the heating cable from mechanical
damage.
3.2
Pre-Installation Checks
Check materials received:
• Review the heating cable design and compare the
list of materials to the catalog numbers of the
heating cables and connection kits received to
confirm that the proper materials are on site. The
heating cable type is printed on its jacket.
• The HWAT System is limited to 208 V or 240 V ser-
vice when using the HWAT-ECO controller. When
using the ACS-30 controller the voltage range is
208–277 V. Ensure that the service voltage avail-
able is correct.
• Inspect the heating cable and connection kits to
ensure there is no in-transit damage.
• Verify that the heating cable jackets are not dam-
aged by conducting the insulation resistance test
(refer to Section 9) on each reel of cable. Do not
power the heating cable when it’s on the reel.
Check piping to be traced:
• Make sure all mechanical pipe testing (i.e. hydro-
static testing/purging) is complete and the system
has been cleared by the client for tracing.
• Walk the system and plan the routing of the heat-
ing cable on the pipe.
• Inspect the piping and remove any burrs, rough
surfaces or sharp edges.
3.3
Installation
• Pay out the heating cable, loosely stringing it along
the pipe, making sure that the cable is always next
to the pipe when crossing obstacles.
• Install HWAT heating cable in straight runs along
the pipe.
Spiraling the heating cable is not
necessary.
