Sentinel X400 has been formulated for the effective cleaning of existing central heating systems where there is a significant amount of corrosion debris.

Sentinel X400 disperses old corrosion products. It is ideal for use where a new boiler or pump is to be fited to an existing system, or where radiators have cold areas or are partly blocked due to sludge build up.

Sentinel X400 is a non-acid formulation which can be used in all types of direct heating systems including those containing aluminium components.

Dosage

1 litre of Sentinel X400 is sufficient to treat a typical domestic system of 8 to 10 radiator panels. Larger systems should be dosed with 2 litres. To clean an existing system in accordance with BS7593: Sentinel X400 should be circulated, preferably at normal operating temperature, with all valves open and the pump turned to a maximum flow for a minimum period of 2 hours or until satisfactory performance is restored. Where systems are badly fouled, a longer period of circulation (e.g., up to 4 weeks) is recommended, but the product will not clear a completely blocked pipe.

There is no limit to the time for which the product can safely be left in the system.

Rapid cleaning may be carried out if Sentinel X400 is used in conjunction with a power flushing device.

Flush the system before refilling and treating with Sentinel X100 inhibitor or Sentinel X500 inhibited antifreeze.
