DRYDEN AQUA DA-GEN Manuale d'uso
Blank display
•
Check if ON/OFF switch is illuminated.
•
Check the connection wire between display and motherboard.
•
Check fuse of the device 3.15 A – it could have tripped due to overload.
•
Check the power supply – 230V/50Hz.
•
If problem persists contact TECHNICAL SERVICE
Electrolysis does not reach the setpoint value
•
Low water temperature.
•
Check salt concentration (TDS) in water.
•
Check cell status (may be incrusted or calcified).
•
Clean the cell according to the instructions in section 4.
•
Clean the flow detector situated in the cell housing.
•
Check titanium 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 don't reach the setpoint value
•
Increase filtration hours to 24 hours
•
Increase electrolysis level.
•
Check the salt concentraion (TDS) in the water. Setpoint value app. 1200 ppm.
•
In an outdoor pool: Add ACO to the water.
•
Check if reactive agents in test kit are expired.
•
Check if the temperature or amount of users has risen.
Electrolysis display shows FLOW
•
Check flow detector cable.
•
Clean incrustations of flow detector at the top of cell housing.
•
Check if system is free of air (probe must be always submerged).
Polarity 1 reaches maximum intensity, but polarity 2 (auto clean) does not reach maximum intensity
•
If salt concentration is correct (1- 2 kg/m
•
When polarity 2 does not reach medium intensity, 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.
WARNING
Keep chemical levels in pool as instructed in this manual.
CLEANING FILTER
Very Important: Make sure the cell is off while cleaning 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 and that you will have to increase chemical levels for the first 5 days.
EARTHING
All metallic components in the pool such as lamps, ladders, heat exchangers, drains or similar elements within 3 m from the pool (10 feet) must be connected to an earth
below 37 Ohms. If using heat exchangers, we recommend them to be made of titanium.
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 precaution. When preparing acid, always add acid to water, never add water to acid, because very dangerous gasses may be
produced.

5 TROUBLESHOOTING

3
MgCl
or 0.75 - 1.5 kg/m
3
NaCl): Cell is reaching its end of life. As of this moment check intensity every 15-20 days.
2
Excess of chlorine in the water
•
Lower electrolysis cell intensity.
•
If your system includes automatic Redox control, check 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.
Titanium 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 the system automatically changes polarity every 300 minutes
approximately.
•
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.
•
Reduce pH set point to 7.0
Alarm AL3 and pH dosing pump stopped
•
The maximum dosing time (standard 200 min.) is accomplished and the acid
dosing pump stops in order to avoid the acidification of the water.
•
To delete the message and to restart the metering press ESC ( ). 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 deposit 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 standardized 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.
