aseko ASIN Aqua Pool Water Treatment & Dosing System Manual

Introduction to the Aseko ASIN Aqua Automatic Pool Dosing System

The aseko ASIN Aqua Pool Water Treatment & Dosing System is a compact automatic controller designed to help maintain balanced pool and whirlpool water with less manual chemical dosing. It monitors key water-treatment parameters and operates dosing pumps to add the required treatment agents according to configured settings.

Instead of relying solely on occasional manual testing, the system supports continuous water management through connected measuring probes, a sampled water line, and automatic chemical injection. This can help maintain more consistent pH and disinfectant levels when the installation is correctly configured and the circulation system operates as required.

The ASIN Aqua is intended for residential pools, smaller commercial installations, and whirlpools with a water volume of approximately 1 to 120 m³, depending on the exact model and configuration. Its touchscreen interface provides access to pool parameters, dosing settings, alarms, and operating information.

Typical users include pool owners, service technicians, and installers who want a compact automatic pool chemical dosing system rather than a fully manual treatment routine. The system is particularly useful where stable water quality, reduced daily intervention, and controlled chemical delivery are priorities.

Correct plumbing, probe calibration, chemical selection, and routine inspection remain essential. Automatic dosing does not eliminate the need to test the water, refill chemical containers, clean filters, or follow chemical-handling precautions.

How to Install and Configure the Aseko ASIN Aqua Dosing System

Switch off the pool circulation equipment and isolate electrical power before beginning installation.
Choose a dry, dust-free wall location between 5 °C and 40 °C. Leave at least 30 cm of clear space around the controller and mount it no higher than the limit stated in the applicable manual.
Install the sampled-water supply after the circulation pump and before the filter. Connect the inlet and outlet in the correct direction, and keep water pressure below 1.5 bar.
Install the pH and disinfectant injection points in the correct order. The pH injection point should be upstream from the chlorine or disinfectant injection point where the installation diagram specifies this arrangement.
Connect the pH tube to the pH pump and the disinfectant tube to the disinfectant pump. Never cross these connections.
Install the probes carefully in their probe holders. Tighten fittings by hand or with the approved plastic tool, and connect each probe cable to its matching input.
Connect the controller to a suitable 230 V, 50 Hz supply protected by appropriate electrical safety equipment, including residual-current protection where required by local regulations.
Power on the system, set the date and time, enter the pool volume, and configure the target pH and disinfectant-control parameters.
Prime the dosing lines, check for leaks, and verify that chemical containers are correctly identified before enabling automatic dosing.

Do not mix chemicals, work on pressurized pipework, or handle dosing agents without suitable protective equipment. If the controller reports a connection or dosing error, stop automatic dosing and inspect the tubing before continuing.

Aseko ASIN Aqua Troubleshooting Guide

System displays an ERROR warning

Open the red ERROR area on the controller to view the fault list. Check the displayed condition, then inspect the corresponding probe, chemical supply, tubing, and hydraulic connections. Clear the cause before resuming automatic dosing.

pH and disinfectant lines are connected incorrectly

A crossed connection can trigger an error after repeated dosing cycles. Confirm that the pH pump draws pH agent and that the chlorine or disinfectant pump draws the correct disinfectant. Correct the tubing and inspect the injection valves before restarting.

Dosing pump runs but chemical level does not change

Check whether the chemical container is empty, the suction tube is submerged, the tube has an air leak, or the injection valve is blocked. Prime the line according to the service procedure and replace damaged dosing tubing.

Measured pH or disinfectant value is unstable

Verify circulation, clean the measuring filter, inspect probe connections, and confirm that the probes are installed in the correct flow direction. Incorrect calibration, insufficient water flow, expired probes, and poor chemical mixing can also cause unstable readings.

Water pressure or flow problem

Inspect isolation valves, the sampled-water filter, pipework, and pressure conditions. The sampled-water circuit must remain within the pressure limit specified for the unit.

Preventive maintenance

Check chemical levels, dosing tubes, injection valves, probe condition, leaks, and alarm history regularly. Calibrate probes using suitable reference solutions and arrange service through the installer or authorized Aseko support channel when electrical, hydraulic, or controller faults cannot be safely resolved.

Pros and Cons of the Aseko ASIN Aqua Pool Water Treatment System

Advantages

Automatic dosing: Reduces the need for repeated manual chemical measurement and pouring.
Compact design: The wall-mounted controller suits many dedicated pool plant rooms and equipment spaces.
Touchscreen operation: Settings, measured values, and alarm information are available through a central interface.
Configurable treatment: Pool volume, pH targets, timing, and other supported parameters can be adjusted to match the installation.
Improved consistency: When probes are calibrated and circulation is reliable, automated dosing can provide steadier water treatment than occasional manual dosing.
Useful for routine pool care: It suits owners who want reduced day-to-day intervention while retaining control over their water-treatment setup.

Limitations

Installation complexity: Correct plumbing, probe placement, chemical routing, and electrical protection are essential.
Ongoing maintenance: Probes, tubing, filters, injection valves, and chemical containers still require inspection and servicing.
Not a replacement for testing: Manual verification remains advisable, especially after commissioning, heavy pool use, unusual weather, or chemical changes.
