1 Overview
Cold applied connection system for use with a ½”NPT thread junction box Danfoss PX or
RX trace heaters.
Catalog No.: 088L0023.
This manual introduces the operation and installation of Danfoss heat shrink connection technology
for use with a ½”NPT thread junction box and the following self-regulating trace heaters:
• Danfoss PX Pipe Trace Heating System
• Danfoss RX-C Roof and Gutter De-Icing System
To connect the trace heater to the cold lead cable the 2 bus wires are insulated with heat shrink tubes,
then connected to the cold lead cable inside the junction box. Additionally, a green/yellow heat shrink
tube is provided to connect the twisted grounding braid to the grounding conductor. Finally, the end
of the trace heater is insulated by means of another heat shrink tube.
The following terms describe the parts of the trace heater within these instructions:
heating matrix
bus wire
insulation jacket
grounding braid
outer jacket
