REMEHA Quinta 115 Technical Information page 37

As most systems contain a variety of metals, it is considered good practice to provide
some form of water treatment in order to prevent or reduce the following:
• Metallic corrosion
• Formation of scale and sludge
• Microbiological contamination
• Chemical changes in the untreated system water

All scale deposits, however small, will reduce the efficiency of the boiler and should be
prevented.
Suitable chemicals and their use should be discussed with a specialist water treatment
company prior to carrying out any work (environmental aspects, health aspects). The
specification of the system and manufacturers recommendations must be taken into
account, along with the age and condition of the system. New systems should be
flushed thoroughly to BS 7593(1992) to remove all traces of flux, debris, grease and
metal swarf generated during installation. Care to be taken with old systems to ensure
any black metallic iron oxide sludge and other corrosive residues are removed, again
by power flushing, ensuring that the system is drained completely from all low points.

Please ensure that the new boiler plant is not in circuit when the flushing takes place,
especially if cleansing chemicals are used to assist the process.
It is important to check the inhibitor concentration after installation, system
modifications, filling the system and every service in accordance with these
instructions.
For the correct dosage and the suitability of inhibitors for use with our boilers and for
further information on water treatment or system cleaning we advise direct contact with
either of the following companies:
