Once a heating system has been power flushed to remove sludge and corrosion deposits, it is important to protect it from further deterioration.
This can be achieved by treating the system water with SYSTEMSAFE-DM, a balanced blend of corrosion and scale inhibitors, formulated to provide complete protection against system corrosion and scale formation. It gives long term protection to central heating systems, preventing internal corrosion, scale deposition and boiler noises. It extends the life of systems and maintains operational efficiency.
At the end of the power flush, and before disconnecting the CLEARFLOW pump, SYSTEMSAFE-DM should be added to the CLEARFLOW tank and circulated through the system for a further three minutes before disconnection. Use one litre per 100 litres system water content, or 1% dosage rate by volume.
APPLICATION & USAGE:
To ensure that all SYSTEMSAFE-DM enters the system, add to the feed and expansion tank after isolating water supply and draining off 15 litres (3 gallons) of water. Allow system to re-fill.
Alternatively, SYSTEMSAFE-DM may be introduced directly into a radiator, using a SYSTEMSURE injector unit.
New Systems: Before adding SYSTEMSAFE-DM to a new system, we recommend a pre-commission cleanse with SYSTEM PRE-CLEAN to remove installation and manufacturing debris such as swarf, grease and jointing paste, to mobilise and remove any dust and dirt, and neutralise any acidic flux residues.
Existing Systems: It should be noted that no corrosion inhibitor can reverse previous corrosion damage, and to optimise the system efficiency, and allow SYSTEMSAFE-DM to work to best effect, we advise that the system should first be flushed with POWER FLUSH FX2 or HYPER-FLUSH. This is particularly important in cases where a new boiler or heat exchanger is being added to an older installation.
Correct dosage: The exact dosage rate is not critical, as SYSTEMSAFE-DM will work effectively within a +/- 20% range, but a Systemsafe-DM test kit is available to check for the optimum treatment level. The test kit determines the level of molybdate, which will be 330 ppm at the standard dosage rate. The kit contains reagents for approximately thirty tests, together with sampling syringe and test tube with colour chart and instructions.
