DESCRIPTION

DA-Gen is a traditional salt electrolyze unit, working by splitting NaCL into Na and CL. By this, chlorine is added to the pool water as main disinfectant. Furthermore, free radicals are produced, which supports the chlorine in killing bacteria. The level of chlorine in the pool water is adjustable to the level the user decides and to the level demanded from the standards demanded from the authorities. The unit should be specified to fit the size of the pool, in order to be able to produce sufficient amount of chlorine.
The content of NaCL in the pool water has influence on the production capacity of the unit. Recommended level is between 2000 – 4000 TDS. The volume of the pool and the TDS will specify the size of the unit. By this, the unit can produce any level of chlorine demanded by user. The specification of the unit can be provided of the distributor of the unit. Hydrogen can be lead away from the unit by installing a pipe connection to outside air.

MAINTENANCE

Weekly checks

SALT CONCENTRATION : ~2000 – 4000 ppm TDS
CELL : Visual inspection to detect incrustations.

Cleaning the Cell
If necessary, carry out a monthly visual inspection. To clean the cell:

Stop the system and close the valves
Place the cell for no more than 10 min. in 3% hydrochloric acid or put it for 2 to 4 hrs in normal vinegar or take a high pressure cleaner.
Once the incrustations have softened remove with a hose to complete cleaning the cell.

DO NOT USE METALLIC OR SHARP OBJECTS TO REMOVE INCRUSTATIONS. Scratching the edges or surface of the cell will make it vulnerable to chemicals, deteriorate the cell and invalidate the guarantee.

General maintenance

The pool must be vacuumed as usual and the skimmers emptied whenever necessary.
FILTER BACKWASHING: At least once a week for 4 to 5 minutes.
VERY IMPORTANT : Make sure the cell is off while cleaning the filter. If the system controls the filtration pump, use the option “backwash” of the programmed filtration mode. See chapter 13 – automatic backwash
Check regularly the level of your pH and APF® bottle to prevent the dosing pump from running dry.
pH / Redox / Conductivity – probes: The probes must be cleaned and recalibrated every 2 to 3 months. To clean the probe insert in electrode cleaner. After each clean the probes must be re-calibrated.

Attention : the probes should never dry out and must be kept wet if stored (when emptying the pool for winterizing, make sure to store the probe head in water).

TROUBLESHOOTING

Blank display

Check if ON/OFF switch is illuminated.
Check the connection wire between display and motherboard.
Check the 3.15 A fuse of the device – it could have tripped due to overload.
Check the power supply – 230V/50Hz.
If the problem persists contact TECHNICAL SERVICE

Hydrolysis does not reach the setpoint value

Low water temperature. Check the salt concentration (TDS) in water.
Check the cell status (it may be incrusted or calcified).
Clean the cell according to the instructions in section 19.
Check that the cell is not worn out (remember that the cell is guaranteed for 5,000 hours, approx. 2-3 years of summer usage).

Free chlorine level doesn’t reach the setpoint

Increase the filtration hours to 24 hours
Increase the hydrolysis level (to 100%).
Increase the salt concentraion (TDS) in the water.
In an outdoor pool: Add ACO® to the water.
Check if the reagents in test kit are in date.
Check if the temperature or number of users has risen.
If you want a higher chlorine level you have to increase the salt concentration. Attention: Higher risk of corrosion!

Hydrolysis display shows FLOW

Check gas and paddle flow detector cable.
Clean for incrustations of the paddle flow detector at the top of the cell housing.
Check to see if system is free of air (gas detector must always be submerged).

Excess of chlorine in the water

Lower hydrolysis cell intensity.
If your system includes automatic Redox control, check the Redox setpoint value. Reduce it by 50 to 100 mV.
If your system includes free chlorine measurment, adjust the setpoint value.
Check redox probe and calibrate it if necessary.
Check the free chlorine probe and calibrate it.

Cell incrusted in less than 1 month

Very hard waters with a high pH and total alkalinity: balance water adjusting pH and total alkalinity.
Check to ensure that the system automatically changes polarity approximately every 300 minutes.
Consult with our technical service to consider accelerating the polarity change (auto-cleaning) . WARNING: Accelerating the polarity change decreases the cell life (5,000 hours) proportionally. Don’t go below 200 minutes!
If the crust is not foaming when in contact with acid, it might be Struvite. In this case do not use anymore MgCl2, use only NaCl.

Alarm AL3 and pH dosing pump stopped

The maximum dosing time (standard 999 min.) is accomplished and the pH-Minus dosing pump stops in order to avoid the acidification of the water.
Delete the message and restart the metering. Do the following verifications in order to preclude errors on the device: Verify if the pH probe reading is correct (if not, calibrate the probe or substitute it with a new one); Verify if the acid/base reservoir is full and if the dosing pump is working correctly; Verify the variable speed of the dosing pump.

Rust on metallic components in the pool

Metallic elements lack standardised earth connection. Contact an electrician to solve the problem.
Rusted components are not stainless steel (minimum 316/V4A/1.4571).
The salt concentration (TDS) is too high.
Attention Stainless Steel parts must be cleaned regularly

Polarity 1 reaches maximum intensity, but polarity 2 (auto clean) does not reach maximum intensity

If the salt concentration is correct : The cell is reaching its end of life. As of this moment check the intensity every 15-20 days.
When polarity 2 does not reach intensity of Polarity 1, we recommend substituting the cell for a new one if it happens during the summer period. If it happens during winter, change the cell before the next summer period.

Dosing pump is not working properly

Check fuse on the right side of the dosing pump
Check (and change) the dosing speed
Check electrical connections
Check tubes and fittings for leaks
Check if injection valve is blocked
Check if suction lance/suction weight is blocked
Check if error message «TANK» appears. If yes replace bottle, if not check the polarity of the suction lance or replace the suction lance

IMPORTANT NOTES

WARNING
Keep chemical levels in pool as instructed in this manual.
CLEANING FILTER
Very Important: Make sure the cell is off while cleaning/backwashing the filter. If the system controls the filtration pump, use the option “filter cleaning” of the programmed filtration mode. See section 5 – Filtration / Filter Cleaning of the General Installation Guide.
VERY IMPORTANT
Remember that the system needs some time to adapt to your pool (up to 14 days)!
SECURITY
To avoid accidents, children should not handle this product unless supervised by an adult. Children should be supervised at all times when in or near a spa, pool or jacuzzi.
HANDLING AND DOSING DANGEROUS CHEMICALS
Chemicals should be handled with extreme caution. When preparing acid, always add acid to water, never add water to acid, because very dangerous gases may be produced.
