4.6.3 Water treatment
The heat exchanger is manufactured from aluminum alloys which will provide many years of excellent service, if
maintained properly. All heat exchangers require proper water conditions to remain ecient and function properly.
Failure to do so will lead to premature failures within the heat exchanger. The system should be lled with mains, cold
water (this will usually have a pH of between 7 and 8). Pressurized installations with a boiler/system content ratio of
1:10 or less should not require water treatment, provided the following conditions apply:
1. The system is ushed thoroughly to remove all uxes and debris and lled completely once.
2. Make up water is limited to 5% per annum.
3. The hardness of the water shall conform to the water quality document requirements
4. All scale deposits will reduce the eciency of the boiler and should be prevented. However provided the above
is complied with any scale produced will not be too detrimental to the boiler eciency and will not reduce the
anticipated life expectancy of the boiler.
WARNING
The boiler water shall be maintained between 7 and 8 ph at all times. Failures to do so will nullify any and all warranties
implied
Suitable chemicals and their uses should be discussed with a specialist water treatment company before to carrying out
any work. The specications of the system and the manufactures recommendations must be taken into account, along
with the age and condition of the entire system. New systems should be ushed thoroughly to remove any traces of
ux debris grease and metal swarfs generated during installation and assembly of a new system
For old systems to ensure any black metallic iron oxide sludge and their corrosives residues are removed, again by
power ushing, ensuring that the entire system is drained and completely clean of all possible debris
