Application & usage:
Loose scale and deposits should first be removed by brush or vacuum cleaner.
Depending on the thickness of scale, make up a solution of one part Scalebreaker LS3 to one, two, or three parts of water. This solution should then be sprayed on to the fouled surfaces once they have cooled down to below 50°C, starting at the top, until all heat transfer surfaces have been soaked.
Deposits immediately begin to effervesce and dissolve. Allow to react for 10 - 15 minutes. Heavily fouled boilers may require a second application.
At this stage, the deposits have been neutralised and will fall away with no further action as the boiler dries out. It can be advantageous to refire the boiler for 10 minutes, causing the treated residues to break up and fall away from heat transfer surfaces.
When cleaning sectional boilers, the use of a 'wet' vacuum cleaner is the most convenient way to removing the damp debris from the floor of the boiler.
CAUTION: As a mild alkaline liquid, Scalebreaker LS3 is safe to handle and does not harm the skin. It should be treated with respect as for any chemical product, and gloves are advised, along with eye protection.
Splashes to the eyes should be washed out immediately with copious quantities of water. Spray equipment should be washed thoroughly after use, in order to avoid corrosion of any copper or brass components.
