Installation Instruction
Danfoss RX-C Roof and Gutter De-Icing System
1 Overview
This manual introduces the installation and operation of trace heating circuits using the following
self-regulating trace heaters:
• Danfoss RX-C Roof and Gutter De-Icing System
The self-regulating trace heater features a temperature-dependent resistive element between two
parallel copper conductors, that regulates and limits the heat output of the trace heater according to
the ambient temperature. If the ambient temperature rises, the power output of the trace heater is
reduced. This self-regulating property prevents overheating which would cause damage to the trace
heater. Even crossing or overlapping with other trace heaters (or other portions of the same trace heater) are possible as given from table on page 13.
The heating system is set up as a fixed equipment heating system for roof and gutter de-icing in ordinary locations. Thanks to the parallel design the trace heater can be cut and installed to any required
length.
Multiple options for connection, splicing and end-termination of the heating circuit are available to
meet the individual requirements on site. A large variety of accessories allows for easy customization
and extensibility.
2 Safety
For safe installation and operation of the RX-C trace heater the technical requirements and instructions
given in this manual must be followed.

10 Trace heater installation
Preparation
Before installing any electric trace heating, the person installing must check if the trace heating has
been designed and planned correctly. It is particularly essential to verify the following points:
• complete project planning documentation, operating instructions and installation instructions.
• correct selection of the trace heater and accessories with respect to:
· calculation of heat losses;
· min. permissible start-up temperature;
· max. permissible operating temperature;
· max. permissible ambient temperature.
Before installing, make sure that the roof covering, gutters and downspouts are properly installed.
Determination of the trace heater length
The total required trace heater length is determined by the length of the roof, the number of valleys
and dimensions of gutters and downspouts.

11 Tests and putting into operation
Measurement of the insulation resistance
The measurement of the insulation resistance is used to determine damage to the trace heater and
possible installation faults. It must be carried out at the following times:
• Preliminary test (shortly before beginning installation of the trace heater on the construction site;
refer to section Acceptance Report on page 19)
• Acceptance test (after the complete installation of the heating circuit or fitting of the thermal insulation; refer to section Acceptance Report on page 19)
• Final inspection (immediately after completion of work on the thermal insulation)
• Upon commissioning
• Before switching on the installation
14 | © Danfoss | 2019.11

Installation Instruction
Danfoss RX-C Roof and Gutter De-Icing System
To do the measurement, proceed as follows:
• Use an isolation tester with a minimum testing voltage of 500 VDC and a maximum testing voltage
of 2500 VDC. Recommended testing voltage: 1500 VDC. Required insulation resistance: > 20 MΩ.
• Measure the resistance between each bus wire of the trace heater and the grounding braid.
• Measure the resistance between the grounding braid and the earth potential (for this measurement
the heating circuit must not be grounded yet).
WARNING:
Risk of fire or electrical shock. If the insulation resistance is insufficient you must fix the heating circuit
before putting it into operation.
NOTICE: The heating circuit must not be grounded.
Acceptance test and acceptance test report
After completion of the installation work (before fitting the thermal insulation) each heating circuit
must be accepted, if possible in the presence of the client.
All further tests must also be documented in an acceptance test report (refer to section Acceptance
Report on page 19).
NOTICE: Claims under warranty will not be considered if the acceptance report is not filled in
completely.
After completion of work on the thermal insulation final inspection and acceptance of the individual
heating circuits is recommended. Usually, this is the task of the client or the final customer (final inspection).
