5.4 Initial Programming

After installation, program the Aquameter according to your specific filter and water hardness settings. Refer to your filter's documentation for its rated capacity.

1. Press and hold the PROG button until the display enters programming mode.
2. Use the PROG button to cycle through settings (e.g., total filter capacity in liters).
3. Use the RESET button to adjust the value for the selected setting.
4. Repeat for all necessary settings, such as water hardness if your filter requires this input.
5. Once all settings are configured, press and hold the PROG button again to save and exit programming mode.

6. Operating

6.1 Reading the Display

The LCD display shows the remaining capacity of your water filter in liters. As water flows through the sensor, this value will decrease. When the capacity reaches a low level or zero, it indicates that a filter change is due.

6.2 Resetting the Meter

After replacing your water filter, the Aquameter must be reset to its full capacity. To do this:

1. Ensure the new filter is installed correctly.
2. Press and hold the RESET button for at least 3 seconds.
3. The display will show the full programmed capacity, indicating a successful reset.

7. Maintenance

7.1 Filter Replacement

Replace your water filter cartridge when the Aquameter indicates that the remaining capacity is low or depleted. Follow the specific instructions provided with your BWT filter cartridge for replacement procedures.

7.2 Battery Replacement

When the display becomes dim or stops functioning, it is time to replace the CR2032 battery. Follow the battery installation steps in Section 5.1.

7.3 Cleaning

Wipe the exterior of the display unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.

8. Troubleshooting

• Display is blank: Check or replace the CR2032 battery. Ensure the battery is inserted with correct polarity.
• No flow reading: Verify that the flow sensor is installed correctly with the arrow pointing in the direction of water flow. Check for any blockages in the water line or sensor. Ensure the sensor cable is securely connected to the display unit.
• Incorrect readings: Re-check the programming settings (filter capacity, water hardness) as described in Section 5.4. Ensure the correct filter type is being used for the programmed settings.
• Leaks at connections: Turn off water supply immediately. Check all connections for proper tightening and ensure sealing washers are correctly seated and not damaged.
