DRYDEN AQUA DA-Gen Pool and Chemical Management for Magnesium Salt User Manual

DRYDEN AQUA DA-Gen Pool and Chemical Management for Magnesium Salt

DESCRIPTION

The DA-GEN® is an innovative water treatment system and additional an intelligent pool controller. The DA-GEN® combines Hydrolysis with Electrolysis with a low mineral content.

The Hydrolysis produces free radicals and other oxygen compounds like ozone, peroxide and persulfate. All these oxidants destroy organic substances and pathogens in the water. Free radicals are the strongest oxidants we know. They oxidise and decompose in a few seconds. To guarantee a safe residual disinfection the DA-GEN® produces a very small amount of chlorine. In combination with Dryden DAISY® we need a very low mineral content of 1 to 2 kg MgCl2 or NaCl per m3.
The DA-GEN® also controls all your pool equipment centrally. Thanks to WiFi you can check and control your pool system 24/7.

INITIAL WATER ADJUSTMENTS

Water adjustments

1. Adjust the alkalinity between 100 and 200 ppm.
2. Adjust the pH to 7.5.
3. Adjust the chlorine between 0.1 and 0.5 ppm.

Attention: Let the system run 24 hours before calibrating and make sure to have a free chlorine level of at least 0.3 ppm!

Adding activator/salt to the water

1. We recommend to add 1 to 2 kg of magnesium chloride (MgCl2) or normal salt (NaCl) per m3 of water. The TDS should be at around 1200ppm. It is recommended to mix them, for example in a ratio of 1:1 to 1:3 (MgCl2:NaCl).
2. Add the magnesium chloride or salt directly to your swimming pool and let the system run.

In outdoor pools it is necessary to use ACO®.

SYSTEM SETTINGS

PADDLE FLOW SWITCH
Connect as shown in the image and contact your installer for activation.

SUCTION LANCE (pH BOTTLE)
Connect the suction lance. The installer/provider should be contacted to activate the sensor.

HYDROLYSIS

1. Hydrolysis: Programming of hydrolysis functions

2. Level:
   Hydrolysis – Desired disinfection production (Always 100%). Boost has no effect, leave as off.

3. Mode: If the device has Free Chlorine and redox probes, choose the parameter that controls the cell’s chlorine generation.

MEASUREMENTS

1. Measurements: Adjustment of setpoints and measuring probes.
2. Setpoints for each measurement.
3. Setpoints:
   pH: 7.4-7.6; redox: 600 – 800 mV; free chlorine: 0.1- 0.5 ppm; conductivity: ~ 2000 μS/cm

Temperature calibration

Free Chlorine calibration
Let the system run 24 hours before calibrating and make sure to have a free chlorine level of at least 0.3 ppm free chlorine!

1. Calibration of the Free Chlorine probe: Recommended at least every 2 to 3 months
2. Calibration with buffer (photometer DPD1): Follow the instructions in 7 steps that appear in the display.
3. Step 1 of 7 – Calibrate Cl at 0 ppm (offset): Close the water flow through the probe and wait for 5 to 60 min until the reading is close to 0. Press OK
4. Step 3 of 7 – Calibrate Cl: Set the water flow to the correct rate of 80-100 litres/hour. Wait for 1 to 10 min until there is a stable ppm reading. Press OK.
5. Step 5 of 7 – Establish the real ppm values with the up/down keys according to your DPD1 (free chlorine) value. Press OK.
6. Step 7 of 7 – If this screen is not shown repeat the calibration process.
   8 Manual calibration: Open the water flow and set the flowmeter (rotameter) to the correct flowrate (50-100l/h). Wait until the current level is stable. Set the chlorine level with the up/down keys, manually (use a manual DPD1 test kit). Press OK when value is correct.

Redox Calibration
The redox value shows the oxidation/reduction potential and is used to determine the sterility of the water. Adjusting the ideal redox level (setpoint) is the last step in the system start up sequence.

Redox control

10.41 Calibration of the redox probe: Recommended at least every 2 to 3 months.
10.42 Calibration with buffer (buffer solution 465 mV): Follow the instructions that appear on the display
10.44 Manual calibration:
Not recommended!

Conductivity calibration
Optional Conductivity probe

FILTRATION

Manual mode

Only with an external pump controller unit

12.11 Filtration:
Configuration control of the filter pump. To set, select Filtration and confirm by pressing OK. The mode selection is done in Mode line with the plus/minus keys.
12.12 Manual:
Manually turns ON/OFF the filtration process. No timing or additional functions. The State (Status) line indicates whether the filtration pump is ON.
Filter Cleaning: See chapter 13

Automatic mode
Without an external pump controller unit

12.21 Automatic
In this mode the filtration is controlled by up to 3 timers.
We highly recommend to run your system in a 24/7 mode with a variable speed pump.
For example: During the night time (6:00 until 24:00 & 0:00 until 10:00) in low speed, during day time (10:00 until 6:00) in medium speed.
To set the ON/OFF times select with the up/down keys in the timer line you want to change (1-3 ).

The plus/minus keys open the selected start time field. Set the time with plus/minus keys. Scroll with the up key to the minute field and set it up with plus/minus keys. To confirm press OK and to cancel press return/escape.
Backwash: See chapter 13

Heating mode

12.31 Heating: This mode acts equally to the automatic mode, but besides it includes the option to work on a relay to control the temperature. The system works with a hysteresis of 1 degree (example: the setting temperature is 23° C, the system will activate itself when the temperature goes below 22° C and will not stop before it passes 23° C).
Use the plus/minus keys to set the desired temperatures
Clima OFF: The heating only works within the set filtration periods.
Clima ON: Keeps the filtration working when the filtration period is finished if the water temperature is below the setting temperature.

Note : Mode only visible if the temperature probe is installed and/or heating is activated in the “Installer Menu”.

AUTOMATIC BACKWASH

1. Backwash Mode with Besgo Valve: The DA-GEN is configured for automatic backwash with Besgo. Use AUX 2!

• Mode: Choose Auto

Attention: If the DA-GEN was once registered at vistapool.com it needs to be removed there by the manufacturer before you can register it at DA-GEN.com. Please contact your dealer.

COVER

17.1 Cover: If the DA-GEN is runned with a frequency controlled pump and if it is connected to the pool cover, the filtration speed will automaticly go to «medium» when the cover is opened. (Please check the filtration speed in Chapter E). Set the Reduction value to 0%!
How to install: If the cover is open, the contact has to be closed and vice versa

AUXILIARY RELAYS

18.2 It is possible to control up to 4 extra auxiliary relays (water attractions, dosing pumps, etc).
In default setting you will only see two available relays: APF® and ACO®: (AUX 1 and 3). AUX 2 is reserved for the Besgo Valve and AUX 4 for the heating and therefore not shown here. If you do not have a heating, you can deactivate it (Chapter C & D in the service manual) and you will get a additional free relay (AUX4).
18.3 Manual mode (ON/OFF).
18.4 Automatic mode: ON/OFF according to a timer that adjusts the start and end of the program. The timers can be configured with a frequency.
18.5 Timer mode: Working time is programmed in minutes. Each time the Shortcut on the front panel is pressed, it will start up and run for the programmed time. This function is recommended for timing of air pumps of spas.
18.7 Rename relays: It is posible to rename each auxiliary relay to suit the use you want to assign. By pressing the plus/minus keys, a pop-up keyboard will appear. Scroll up and down with the up/down keys and left to right with the plus/minus keys. To select a letter press the OK.

MAINTENANCE

Monthly checks

SALT CONCENTRATION:
~1200 ppm TDS
~2000 μS/cm

HYDROLYSIS CELL: Visual inspection to detect incrustations.

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

1. Stop the system and close the valves
2. 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.
3. 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

1. The pool must be vacuumed as usual and the skimmers emptied whenever necessary.

2. FILTER BACKWASHING: At least once every 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

3. Check regularly the level of your pH and APF® bottle to prevent the dosing pump from running dry.

4. 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 winterising, 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

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.

Hydrolysis does not reach the setpoint value

• Attention: At 1200 TDS, 50 – 80% and the warning “LOW” is normal
• 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).

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.

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. Setpoint app. 1200 ppm.
• 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!

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.

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).

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 (1- 2 kg/m3 MgCl2 or 0.75 – 1.5 kg/m3 NaCl): 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.
