CHEMICAL BALANCE
It is imperative that correct chemical balance be maintained in your pool and spa water, otherwise corrosion of
your heater may occur. Corrosion of the heat exchanger voids warranty. Your local pool shop specialist or
spa retailer can advise correct chemical balance. Your water should be checked and maintained regularly by a
pool water professional. As a guide the following parameters may be used.
pH 7.6 to 7.8
Total Alkalinity 80 to 120 ppm
Calcium Hardness 150 to 250 ppm
Salinity 4000ppm max. Excessive salt can damage your heater.
You should test your water chemical balance at least on a weekly basis.
Excessive sanitiser can damage your heater. Chlorine should not exceed 3 ppm and bromine should not exceed 5
ppm. Salt chlorinators, especially when used on spa pools or indoor or covered pools, can easily produce
excessive chlorine levels which will damage the heater internals.
