Original Instructions (English)
Thermal cycling, corrosion and vibration can cause degradation of thermal system and electrical
interfaces. Follow system designer’s guidelines for periodic checking the condition of the
installed heater and the electrical connections.
Check line connections on a regular basis (6 months recommended) to make sure they are tight,
free of oxide build-up, and that no dust or dirt build-up is present. Retighten as necessary per the
instruction found in Wiring Section of this manual.
If an enclosure is provided, check enclosure (inside) for rust, dirt or dust. Remove rust if present,
with steel wool (or equal) and thoroughly blow clean with dry, oil-free air. If enclosure is moisture
resistant, check condition of cover gasket. If the gasket is damaged or is in needed of
replacement, please contact the factory for further assistance in resolving this issue.
Thermal cycling may cause sealed joints to relax causing a leak. Inspect all sealing-related
features and replace gaskets and/or tighten connections if necessary.
