Sentinel
X400 has been
formulated for the effective cleaning of existing central heating systems where
there is a significant amount of magnetite corrosion debris and sludge.
Sentinel
X400
disperses old corrosion deposits and sludge. It is ideal for use where a new
boiler or pump is to be fitted 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 indirect heating systems
including those containing aluminium components.
Dosage:
1 litre
of Sentinel X400 is sufficient to treat a typical domestic system
of up to 10 radiators. Larger systems
should be dosed with 2 litres. To clean an existing system in accordance with
BS7593: 2006 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.
The
product is not aggressive and can be safely left in the system for extended
periods.
Rapid
cleaning may be performed 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.
Feeding:
Open
Systems: Dose via
F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel.
Sealed Systems: If the system is empty, add to any convenient point
before filling. If full, use a Sentinel Dosing Vessel to inject via the
filling loop or other access point.
