WARNING
WATER CHEMISTRY
All Waterco Limited portable spa and bath pumps have been designed to withstand the
harsh environments of spa or bath systems. Non corrosive (non metallic) materials are used
extensively, however metal parts are used in the heater element.
The heater element can be damaged due to incorrect chemical balance of the spa water. It is
very important to maintain the chemical balance of your spa. By doing so you will help prevent
corrosion of the heater element and ensure a long, trouble free life.
The chemical balance of water is a relationship between its pH, total alkalinity, calcium
hardness and water temperature. Testing kits are available to test water yourself or alternatively
a professional pool and spa shop can test your water to ensure that it is chemically balanced in
accordance with the Langelier saturation index.
Chlorine levels should not exceed
5.0ppm
and have an ideal range of between
1.5ppm &
3.0ppm
. It is recommended that in water that exceeds 30°C, you should use bromine as an
effective sanitizer with a similar concentration to chlorine.
High levels of chlorine, bromine and ozone may corrode the heater element and stainless steel
components as well as the pump mechanical seal.
Extremely hard water above 300ppm of calcium with a high pH level can cause scaling of the
heater element. This will cause a reduction in heating efficiency.
NEVER ADD CHEMICALS TO YOUR SPA VIA YOUR SKIMMER BOX.
When adding chemicals always mix them into a bucket of water and evenly disperse the mixture
over the spa surface.
The water must be maintained at all times to the following
