ORP / RESIDUAL chlorine control: input for potential-free contact.. This input can be used to make the electrolysis system
interact with an external controller (ORP, RESIDUAL CHLORINE, PHOTOMETER, etc.). It will be enough to connect two wires
from the potential-free contact located in the external controller, to the corresponding input [or] located in the control board of the
Smart+ unit.
4.8. Start-up
1. Check that the filter is 100% clean, and ensure that the swimming pool and the installation do not contain copper, iron or algae. Ensure
that any heating equipment on the pool is suitable for use in salt water.
2. Ensure that the swimming pool water is balanced. Balanced water enables the chlorine that is produced to be used more efficiently and
effectively, and ensures that the life of the electrodes is prolonged. Water should be maintained within the parameters shown below:
a) pH must be in the range 7.2-7.6
b) Total alkalinity must be in the range 80-120 ppm
3. Although the AstralPool Chlore Smart+ system can work at a salinity range of 4–6 g/l, try to maintain the recommended minimum salt level
3
of 5 g/l, by adding 5 kgper m
of water if the water does not already contain salt. Always use common salt (sodium chloride), without additives
like iodides, that is "apt for human consumption". Never add the salt through the cell. Add it directly to the swimming pool or into the balance
tank.
4. When adding the salt, and in case the swimming pool is going to be used immediately, carry out a treatment with chlorine. An initial dose of
3
2 g/m
of trichloroisocyanuric acid may be added.
5. Prior to starting up the salt chlorinator, disconnect the power supply to the salt chlorinator and run the pump for 24 hours to ensure that the
salt is completely dissolved.
6. Next, reconnect the power supply and turn on the salt chlorinator, locating the production level so that free chlorine concentration stays
within the recommended range (0.5 – 1.5 ppm).
NOTE: in order to establish the free chlorine level you will need to use a test kit.
7. In outdoor swimming pools it is advisable to maintain a level of 25-30 g/m
ppm should be never exceeded. This will help to stop the chlorine that is in the water from being destroyed by the sun.
