T.D.S. (Total Dissolved Solids) :
The chemicals which are introduced into the pool water leave by-products which can build up over a period of
time, such as chlorides and sulphates.
T.D.S. can only be reduced by dilution with fresh water. Dilution occurs every time the pool filter is back washed.
The T.D.S. level MUST not exceed 1500 mg/L.
DISINFECTANT LEVEL :
Free chlorine is most important in relation to swimming pool disinfection. In chlorine treated pools a free chlorine
residual of at least 1mg/L should be maintained at all times. The free chlorine level MUST be maintained
between 1 and 3 mg/L.
If bromine is used, the level must be maintained between 2 and 3 mg/L.
If ozone is used, the level must be maintained between 0.8 and 1.0 mg/L.
If baquacil is used, the level must be maintained between 25 and 50 mg/L.
SALT PURIFICATION SYSTEMS :
The Heatstar is not warranted for use in conjunction with any form of salt chlorination of electrolytic system due
to potential concerns of an enhanced risk of corrosion. The warranty exclusion relates only to corrosion damage.
ELECTROLYSIS :
Electrolysis can be caused by a bad or non-existent earth connection. Faulty electrical insulation on any
apparatus connected in the system will allow electricity to run to earth via the metal components in contact with
the swimming pool water.
This will create a cathode / anode effect and may lead to metal components being damaged.
INCORRECT WINTERISATION :
If the Heatstar and filtration system are not required to be in operation for a period of time and are not flushed
with fresh water, then the conditions of the stagnant pool water retained within the system may prove damaging
as the water evaporates to leave increased concentration of corrosive chemicals.
The essential requirement is that the water should be properly balanced - that it is neither corrosive nor scale
forming when measured by the Langelier Saturation Index.
As the condition of the pool water and the design of the disinfection system are obviously beyond the control of
the manufacturers, no warranty claim can be accepted if the product has been damaged in any way due to any
form of corrosion.
Please look after your Heatstar.
