Water Quality Guidelines
TH - Total hardness is caused by calcium
and magnesium.
pH –this measures the alkalinity of the
water, neutral alkalinity is pH7. Heating
systems require an alkaline pH. Lower
pH will increase the corrosion risk.
TDS –. dissolved solids in the system
and is a measure of the cleanliness of
the water. (satisfactory level should be
within TDS of 10% of the mains water) .
Conductivity –this is the measure of the
ability of water to pass an electrical
current.
Free copper –the level of copper in the
system.
Total Iron and Manganese –this
measures iron concentration in mg/litre.
These are strong oxidants and may
increase the risk for corrosion.

Typical Water Quality Guidelines

14 2551988C
Visual inspection should be carried out ensuring that the water is clear, bright and free from
particulate matter. The system must be fully vented, pressurised and dosed with anti-corrosion and
anti-bacteria growth inhibitor.
Dosing Secondary System
Once the system is cleaned and flushed the inhibitors should be added to the secondary side to
prevent the corrosion or bacteria growth.
A suitable long term corrosion inhibitor and inhibitor for preventing the bacteria should be
introduced in a proportion of the system volume.
Excessive filling of the secondary circuit with untreated water may lead to scale
build up and corrosion. This may damage the ModuSat unit or reduce the
performance.
Please confirm with the water treatment consultants that the chemicals used and
cleaning method statement complies with the requirements set out in this
section.
Evinox Energy do not take responsibility for approving inhibitors used for dosing
the system.
Warranty due to Water Quality
The warranty of the ModuSat unit is strictly related to the instructions and procedures indicated in
this manual and the warranty does not cover any damage caused by scale and/or corrosion resulting
from poor water quality.
The components and materials used in the system assembly should also be checked to ensure they
do not contribute to dissolved oxygen that can cause corrosion.
Also:-
Ensure there is no air in the system
Ensure there are no “dead” legs in the system
Remove gas permeable parts and materials
