1. Product Overview
The Aquasure Serene Lite 800K Whole House Water Conditioning System is a 3-in-1 bundle designed to provide comprehensive water treatment for homes with 1 to 3 bathrooms. This system includes a Salt-Free Conditioning/Descaling System, a Triple Purpose Pre-Filter, and an 8 GPM Light System, working together to improve water quality throughout your home.
The Salt-Free Water Conditioner prevents scale build-up in plumbing and appliances without using salt. The Triple Purpose Sediment/Carbon/Zinc Pre-Filter offers a 5-stage filtration process, reducing contaminants such as sediment, chemicals, chlorine, VOCs, odors, taste, soil, sand, rust, and organic matter. The 8 GPM Light System provides an additional layer of water purification.

4. Installation Guide
Installation of the Aquasure Serene Lite 800K system should be performed by a qualified professional to ensure proper function and adherence to local plumbing codes. The system is designed for municipal water sources with hardness levels below 25 grains/gallon.
Installation Considerations:
- Location: Choose a suitable location that is protected from freezing temperatures and direct sunlight, with adequate space for maintenance.
- Water Pressure: Ensure your home's water pressure is within the system's operating range. The system is designed for optimal performance with a high flow rate of up to 10 GPM.
- Pre-assembled Design: The system comes largely pre-assembled, and the anti-scale media does not require cleaning or drain lines.

5. Operation
The Aquasure Serene Lite 800K system operates continuously to treat your home's water supply. Water enters the system and undergoes a multi-stage treatment process:
- Triple Purpose Pre-Filter: This is the first stage of defense, reducing contaminants such as sediment, chemicals, chlorine, VOCs, odors, taste, soil, sand, rust, and organic matter.
- Conditioner with Catalytic Media: The water then flows through the conditioning tank containing catalytic media. This media converts dissolved minerals into microscopic crystals that remain suspended in the water, preventing them from adhering to surfaces and forming limescale build-up. The conditioner imparts a negative charge to these crystals, reducing their attraction to pipes and surfaces.
- UV System: Finally, the water passes through the 8 GPM Ultraviolet (UV) System. This system eliminates harmful waterborne pathogens and microorganisms, providing an additional layer of purification.
The system maintains a high flow rate of up to 10 GPM, ensuring that water pressure is not significantly affected during operation.
6. Maintenance
Regular maintenance is essential to ensure the optimal performance and longevity of your Aquasure Serene Lite 800K system.
- Pre-Filter Replacement: The Triple Purpose Sediment/Carbon/Zinc Pre-Filter should be replaced every 6 months for optimal filtration performance.
- UV Light Replacement: The UV lamp in the 8 GPM Light System should be changed annually (every 12 months) to ensure effective water purification.
- Anti-Scale Media: The anti-scale media within the main conditioning tank is designed to last for 10 years and does not require regular cleaning or replacement within this period.
