(ii)
Phosphates: should be less than (<) 200 ppb (Parts per billion)
Phosphates are food for algae and will increase chlorine consumption thus shortening cell life if present in water.
Remove phosphates with Saltline approved Phosphate Remover.
Possible Chemistry Problems
(i)
The use of sulphate containing chemicals may promote the production of oxygen compounds at the cell, which
can lead to slightly lower chlorine production, and the production of chemicals which can adversely affect ORP
probes. Chemicals to avoid
- Sulphuric acid and Sulphate flocking compounds
Note: the use of potassium monopersulphate is acceptable.
(ii)
The use of quaternary ammonium compounds (Quats) as an
algaecide can promote turbidity (cloudiness). This is caused by the very high
chlorine levels in the cell reacting with the Quats compound. A common Quats
compound is
benzalkonium chloride (also known as alkyldimethylbenzylammonium chloride or ABDAC).
(iii)
The use of Citric Acid as a “black spot remover” will cause the chlorine residual reading in the pool to fall to zero
for an extended period of time.
(iv)
Hydrogen peroxide, peroxygen chemicals and peroxide in general do not interfere with the ECO-matic System
but can seriously affect the ORP probes (redox probes) on chlorine/redox/ORP controllers.
MAINTENANCE
DAILY
1. Ensure all indicator lights are Green in Control Box
2. Ensure fan is running in Power Supply.
3. Ensure all cords attached
4. Ensure water is balanced to L.S.I.
5. Ensure that chlorine levels are between 1-3 ppm of free available chlorine for swimming pools and 2-5 ppm of
free available chlorine for spas.
WEEKLY
1. Ensure Flow Rate to cell is to spec
2. Inspect SaltPro to see if it is being attacked (look for signs for erosion)
MONTHLY
1. Ensure all connections (especially DC Cords) are snug
2. Inspect cell for build-up between blades and clean
only if necessary
SEMI ANNUALLY
1. Turn off Power Supply
2. Tighten all internal connections
3. Ensure all wire loomes are in good order
