System Restorer for Hydronic Heating Systems
Features & Benefits
• Effectively removes radiator sludge

• Easy to handle
• Neutral pH -no neutralisation procedure is
needed
• Manufactured under a quality system
conforming to ISO9001
Application
Sentinel X400 has been formulated for the effective
cleaning of existing hydronic 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
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 that can be
used in all types of indirect heating systems including
those containing aluminum components.
Dosing & Feeding
1 quart of Sentinel X400 is sufficient to treat a typical
residential system of 25 gallon. Larger systems
should be dosed at 1% of system water. To clean an
existing system, Sentinel X400 should be circulated,
preferably at normal operating temperature, with all
valves open and the pump turned to 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.
Open Systems: Dose via F&E cistern, via a
by-pass feeder or use a dosing vessel.
Sealed Systems: If the system is empty, add to any
convenient point before filling. If full, use a dosing
vessel to inject via the filling loop or other access
point.
