Security information, installation and maintenance
For detailed information, refer to the Installation and Maintenance Guide (IM-P180-05) supplied with the product.
Installation Tip:
The product is designed to be installed on vertical piping with the flow directed downward to ensure free discharge of condensate. Do not expose the thermostatic element to excessive heat as this may damage the element. Suitable shut-off valves should be installed before and after the trap to ensure safety during maintenance and replacement.
