Pre-Installation Guidelines
Before attempting to install the heating cable, read this in-
struction sheet and those enclosed with the accessories to
familiarize yourself with the products. Complete the following
pre-installation steps:
• Verify that the selection of heating cable type and rating
is in accordance with the procedures located in the ap-
plicable application design guide.
• Ensure that the voltage rating of the heating cable is ac-
ceptable for the available service voltage.
• Walk along the pipe segment that is to be traced and plan
out the path for the heating cable on the pipe.
• Remove any obstacles or sharp edges that are present
along the pipe segment.
• Open package and visually check for breaks or nicks in
the cable jacket. File claim with carrier if any damage is
found.
• After removing the cable from the carton or wrapping,
measure the insulation resistance of the unit from buss
wires to braid at 2,500 VDC to assure the cables have not
been damaged during shipping and handling. If the cable
has no braid, uncoil the cable onto a metal surface and
check resistance between the buss wires and the metal
surface. See Table 4 for acceptable minimum insulation
resistance readings and page 32 for a detailed explana-
tion on how to conduct the insulation resistance test.
ELECTRIC SHOCK HAZARD. Any cable with an in-
sulation resistance reading less than 20 megohms
before installation should not be installed. Contact
your local Chromalox representative.
• Ensure all pipes, tanks etc. have been hydrostatically
tested prior to the installation of the heating cable.
• Ensure all cable ends, connections, and surfaces are dry
prior to installation.
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heating cable. Failure
to do so could result in personal injury or property
damage. Heaters must be installed by a qualified
person in accordance with IEC 62086-2:2001.
Any installation involving electric heating must be
effectively grounded in accordance with IEC 62086-
2:2001 to eliminate shock hazard.
