Application
Sentinel X400 Rapid-Dose
has been formulated for the eective cleaning of fouled hydronic heating systems
which may contain corrosion debris and other sludge. It is ideal for use where a new boiler or pump is to be tted
to an existing system, or where radiators have cold areas or are partly blocked due to sludge build up. The product
is a non-acid formulation which can be used in all types of indirect heating systems including those containing
aluminium components.
Dosing
One can of Sentinel X400 Rapid-Dose is sucient to clean a typical domestic system of 25 gallons. Larger systems
should be dosed with two cans. The product should be applied via the boiler drain valve using the dedicated dosing
connector provided. The system should be less than 33 p.s.i when the product is applied. Never attempt to dose into a
hot system.
To clean the system, Sentinel X400 Rapid-Dose should be circulated, preferably at normal operating temperature,
with all valves open and the pump turned to maximum ow 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 3 weeks) is
recommended. There is no limit to the time for which the product can safely be left in the system. Flush the system
before relling and dosing with Sentinel X100 Rapid-Dose
.
