Product Data Sheet

Safety Data Sheet

Underfloor central heating systems or other lower temperature hot water systems can be vulnerable to contamination from bacteria and fungi due to the lower system temperature and slower flow rate than a traditional panel radiator heating system. Sentinel X700 Biocide prevents the development of bacteria and fungi and their associated problems, such as blockages, unpleasant smells, and corrosion within the system.

For efficient operation of an underfloor heating system, it should be treated with Sentinel X700 Biocide and Sentinel X100 Inhibitor at first fill or following a clean.

In new systems, add 1 litre of Sentinel X700 Biocide during the final fill of the system. In larger systems, the product should be dosed at 1 litre per 300 litres system volume. Circulate the system for 30 minutes to ensure complete distribution through the whole system.

This product should not be mixed with other types of cleaning product other than those specified by Sentinel.

This product is only for use in the primary circuit of underfloor heating systems.
