Chlorine Production; General Information; Trouble Shooting - Davey EcoSalt 2 DES2-15E Instructions D'installation Et D'utilisation

CHLORINE PRODUCTION

The EcoSalt2 must be run daily to generate sufficient chlorine to sanitise the pool. During summer a typical
installation would require eight hours per day of chlorination. Depending on when you choose to run the
EcoSalt2, it is best to test the residual Chlorine in the pool at the point where you would anticipate the levels
be at their lowest. At that chosen time of the day, if the residual Chlorine level from your test is reading too
high, reduce the EcoSalt2 CHLORINE OUTPUT. Alternatively, if the residual Chlorine level from your test is
reading too low, increase the EcoSalt2 CHLORINE OUTPUT (refer to page 13). Correct chemical balances
(see page 29) are critical to ensure the EcoSalt2 performs correctly.
In cooler times of the year, it's typically possible to reduce running hours of the EcoSalt2. Follow instruction
from your pool professional. Chlorine output can also be reduced throughout this time by entering WINTER
MODE, (see page 19).
"SHOCK" TREATMENT
Periodically, especially during extremely hot conditions, it may be necessary to boost the chlorine level in the
pool. This can be achieved by selecting BOOST MODE, which will run the system on full for 24 hours, (see
page 15). Alternatively, add either liquid, or granulated chlorine. If granulated chlorine is added, the cell must
be checked regularly, since the additives from this product can clog the electrodes.
CHLORINE TYPES AND COMPARISONS / MAX POOL SIZE
Many chlorinator manufacturers calibrate their units to compare with 65% granulated chlorine, making it
necessary to adjust their readings to a lower level in order to determine true chlorine production. Below is a
comparison table of the available types of chlorine used to sanitise pools.

NOTE: The appropriate EcoSalt2 for your pool is dependent on the local climate,
bather load of the pool and running times. Please note that the EcoSalt2 cell life can be
increased with shorter running times during winter and lower output settings. Davey
recommends the EcoSalt2 be run for between 6 - 8 hours a day during summer, and 4
hours during winter.

TROUBLE SHOOTING

No Chlorine Production - Check for:
1. No power to system
2. Insufficient flow from pump
3. Control set to manual off
4. CHLORINE OUTPUT set to "0" setting
5. Dirty cell
6. Filter needs back washing
7. Flow switch not connected or damaged
8. Salt level too low triggering low salt cut-out
9. Main house fuse blown
10. Pump faulty
Low Salt Alarm:
1. Check salt level (within operation range)
2. Check temperature (above 15°C)
3. Clean the cell
