Troubleshooting - Davey PoolFresh Instructions D'utilisation

Algae - Microscopic forms of plant life which enter the pool by rain, wind and dust. There are numerous
varieties - some are free floating whilst others grow on walls and in cracks and come in different colours.
Some are more resistant to chemical treatment than others.
Bacteria - The germs that contaminate your pool - generally introduced by swimmers, dust, rain storms and
other elements.
Balanced Water - The correct ratio of mineral content and pH level that prevents pool water from being-
corrosive or scale forming.
Chloramines - Compounds formed when chlorine combines with nitrogen from urine, perspiration, etc.
Chloramines cause eye and skin irritation, as well as unpleasant odours.
Chlorine Demand - The chlorine required to destroy germs, algae and other contaminants in the pool.
Chlorine Residual - The amount of chlorine remaining after chlorine demand has been satisfied. This is the
reading obtained with your test kit.
Cyanuric Acid - Also known as stabiliser or conditioner. It reduces dissipation of chlorine by direct sunlight.
Only needed in outdoor pools
Liquid Acid - Chemical used to reduce the pH and total alkalinity in the pool water, and for cleaning
chlorinator Cell.
ppm - An abbreviation for Parts Per Million the accepted measurement of chemical concentration in
swimming pool water. I ppm- l mg/L.
WARNING:
Do not add Hydrogen Peroxide to pool water or through swimming pool hydraulic or
sanitiser system. Use of Hydrogen Peroxide will void warranty on Davey products.
TROUBLE SHOOTING
No Chlorine Production - Check for:
1. Main power outlet switched off or Chlorinator not connected to mains supply.
2. Chlorinator fuse blown
3. Cell needs cleaning
4. Filter needs backwashing
5. Flow Switch not connected or incorrectly installed
6. Running times incorrect
7. Main house fuse blown
8. Low / No flow from pump
Low Chlorine Production - Check for:
1. Dirty Cell - clean if required
2. Filter needs backwashing
3. Not set at correct production level/Cell failing
4. Pool stabiliser too low or Salt level to low
5. pH too high
6. Running times too short
