Use and Maintenance
Each snow season:
• Check cable position
• Ensure all debris is removed
• Inspect cable for damage, deterioration
• Test GFI devices
When to operate the heating system:
Operate the RX system in the winter season when temperatures fall between 15 °F to 35 °F (-9 °C to +2 °C).
In very cold temperatures, the RX system may not generate enough heat to prevent the formation of ice
dams. Turn off the system when ice dams have melted or temperatures are greater than 35 °F (2 °C).
In the off season the system may remain on the roof. Disconnect the system to ensure it isn’t accidentally
turned on. Never operate the system when ambient temperatures are above 50 °F (10 °C) to prevent
cable damage or fire hazard.
During the winter season, ensure the system is working efficiently by observing the melting path created
by the heating cables. Cable layout modification may be required to adapt to changing ice dams or
incorrect design.
Use a weather-proof power outlet to prevent accidental GFI tripping.
An optional automatic system controller is available. Ask your Danfoss representative for details
