INSTALLATION PROCEDURES
Attachment Tape
(Value Represents Approximate Linear Pipe Length Allowance Per Roll)
Where space is a problem, Thermon approved plastic cable
ties may be used on the same interval as tape. Do not over
tighten cable ties.
NO NOT attach cable to pipe with metal hose
clamps, metal strapping, tie wire or similar
materials. Damaged to cable and system could
result.
Avoid pinch points when installing cable. Over
the course of time, the pipe will move due to
vibration, thermal expansion, contraction and
building settling. Do not allow the heating cable
to bind between items such as pipe supports,
wall or floor penetrations.
Pipe supports: Run the heating cable on the outside of any
pipe hanger or support that comes in contact with the pipe.
Thermon recommends the use of insulated pipe supports to
prevent additional heat loss at the point of support.

Installing Cable on Pipe. . .
1. Placement Of Cable
The HSX cable will be installed on the pipe in a parallel pass.
There is no need for spiral wrapping. Locate the cable in the
10 or 2 o'clock position where possible. If accessibility is
a problem the cable may be installed in the 4 or 8 o'clock
position.
Insulated Pipe Support: For cork or polyurethane insulation
insert, cut small hole for cable to pass through.

2. Attaching Cable to the Pipe
The HSX is held in place with temperature-rated attach-
ment tape (FT-1L). Circumferential bands of tape should be
installed at 300mm (12") intervals to ensure the cable main-
tains proper contact with the pipe.
