General installation guidelines
Unless otherwise specified, guidelines specified in this section apply, regardless of the type of coating used for
embedding the heating cable.
Please review installation guidelines before starting the installation. Be sure to adhere to all construction codes
and regulations applicable in your area.
4.1. Preparation of foundation
• The heating cable system for snow melting should be installed on a foundation capable of withstanding envi-
ronmental conditions as intended for the application while also providing a long-term structural stability.
• The granular foundation should allow for adequate drainage of melting snow and ice. Provide an additional
drain where necessary.
Note: Thermal insulation is not required but could improve the performance and energy efficiency of the OWS-T
snow melting system. Consult with an architect or engineer to ensure the structural integrity of the thermal
insulation and its appropriate location. The cable should not come into contact with thermal insulation.
4.2. Equipment verification
• Be sure the OWS-T heating cable power output is sufficient for the area to be heated.
• Be sure the OWS-T rated voltage is equivalent to the system’s rated voltage. Never connect a product designed
for 208/240V to 347V.
• Perform all insulation and resistance tests before breaking the integrity seal and enter results in the
measurement table.
• Connect the OTM-CC electrical fault indicator to the free end of the cold lead to ensure the integrity of the
heating cable throughout the entire construction period. Reconnect the electrical fault indicator to the cold
lead after each test phase.

Never cut or shorten the heating cable.
Never connect a product designed for 208/240V to 347V.
If the electric fault indicator sounds during installation or
embedding procedures, mark the location where the cable was
damaged. Delineate an area of at least 2 sq. ft. (0.2 sq. m) around
the damaged section of the cable and do not cover that area.
Proceed with the installation. Repair the cable with the OW-KIT
repair kit. If you need assistance with the repair, contact Ouellet
Canada’s specialists at:1 800 463-7043.
