4. Setup

The BWT Perla One water softener is designed for standalone installation. It is recommended that installation be carried out by a certified plumber.

4.1. Choosing an Installation Location

• Select a dry, level, and frost-free location near the main water supply inlet.
• Ensure adequate space for maintenance, salt replenishment, and access to connections.
• The location must have access to a suitable drain for the regeneration wastewater.

4.2. Connecting to Water Supply

1. Shut off the main water supply to your home.
2. Install the Multiblock X DN 32 and the Connection Kit DN 32/32 DVGW according to the provided diagrams (not included in this manual, refer to separate installation guide).
3. Connect the water softener's inlet and outlet to the plumbing system using the flexible hoses. Ensure all connections are secure and watertight.

4.3. Drain and Overflow Connections

1. Connect the 2m Flush Hose and the 2m Overflow Hose (18 x 24 mm) to the designated ports on the softener.
2. Route these hoses to a suitable drain, ensuring there is an air gap to prevent back-siphonage. Install the BWT Siphon as per local regulations.

4.4. Adding Regeneration Salt

1. Open the lid of the water softener.
2. Fill the storage tank with BWT-approved regeneration salt. The tank can hold up to 32 kg of salt.

4.5. Initial Startup and Programming

1. Slowly open the main water supply valve to allow water to fill the softener. Check for leaks.
2. Plug in the power cord (if applicable). The microprocessor control will guide you through the initial setup.
3. Use the AQA Hardness Tester to determine your incoming water hardness.
4. Program the water softener with your specific water hardness settings using the control panel. Refer to the separate programming guide for detailed instructions.
5. Initiate a manual regeneration cycle to flush the system and prepare it for operation.

5. Operating

The BWT Perla One operates automatically once properly set up. It uses AQA Perla technology with microprocessor control for efficient and easy operation.

5.1. Automatic Softening

The system continuously monitors water usage and automatically initiates regeneration cycles as needed. It offers 24 hours of soft water operation for 1 to 2 residential units.

5.2. Regeneration Process

During regeneration, the softener flushes the resin bed with a brine solution to remove accumulated hardness minerals. This process is typically scheduled for times of low water usage (e.g., late at night) to minimize inconvenience. The intelligent regeneration system ensures economical use of salt and rinse water.

5.3. Monitoring Salt Levels

Regularly check the salt level in the brine tank. When the salt level is low, replenish it with BWT-approved regeneration salt to ensure continuous soft water supply. The system may provide an indicator for low salt levels.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your BWT Perla One water softener.

6.1. Salt Replenishment

As mentioned in the operating section, regularly check and replenish the salt in the brine tank. It is recommended to keep the tank at least one-quarter full. Use only high-quality water softener salt.

6.2. Brine Tank Cleaning

Periodically (e.g., once a year), inspect and clean the brine tank. This involves removing any salt crusts or sediment that may accumulate at the bottom. Refer to the detailed cleaning instructions in the full product manual.

6.3. System Inspection

Annually, inspect all connections, hoses, and valves for any signs of wear, corrosion, or leaks. Ensure the drain line is clear and free of obstructions. If any issues are found, contact a qualified service technician.

6.4. Resin Bed Maintenance

While the resin bed is designed for long-term use, certain conditions (e.g., high iron content in water) may require specialized cleaning or replacement over time. Consult a professional if you suspect issues with the resin bed.
