How It Works
The Aquasure Harmony Series water softener utilizes an ion exchange process to remove hard minerals from your water. Hard water enters the system, and as it passes through the resin beads, calcium and magnesium ions are exchanged for sodium ions. During regeneration, a brine solution flushes the accumulated hard minerals from the resin, sending them to the drain, and recharging the resin for continued softening.

Installation Guide
This section provides a general overview of the installation process. For detailed, step-by-step instructions, always refer to the comprehensive user manual included with your product. Professional plumbing assistance is recommended if you are unsure about any steps.
Pre-Installation Considerations
- Ensure you have basic plumbing tools: channel locks or adjustable wrench, Phillips head screwdriver, plumber's tape, utility knife, and silicone grease.
- Confirm access to a 120-volt outlet within 6 feet of the softener for the electronic control valve.
- The softener needs to be placed as close as possible to a floor drain or other acceptable drain point (e.g., sump, laundry tub, standpipe) to prevent air breaks and backflow.
Installation Steps Overview
- Shut Off Main Water Supply: Locate and completely turn off the main water supply valve to your home. Test a nearby faucet to confirm water is shut off.
- Mounting the Control Valve: Lubricate the bypass valve and the back O-rings of the control head with food-grade silicone grease. Attach the bypass valve to the control head, securing it with metal plates and screws. Lubricate the inner and outer O-rings on the bottom of the control valve. Install the upper basket onto the bottom of the valve. Insert the riser tube into the tank, ensuring it's flush with the top. Place the upper basket over the distributor tube and push the valve onto the tank, threading it clockwise until hand-tight. Do not use tools to overtighten.
- Connecting the Softener: Apply 8 to 12 wraps of plumber's tape to the bypass inlet and outlet fittings. Connect the inlet and outlet of the softener using appropriate fittings, ensuring all connections are secure to prevent stress. Connect the 1/2-inch drain hose to the quick-connect fitting on the control head, securing it with the locking clip. Run the drain hose to the nearest laundry tub or floor drain, ensuring no sags or drops.
- Connecting the Brine Tank: Connect the brine line to the control valve by removing the blue locking clip, pushing the brine line into the connector, and securing it with the locking clip. Pour 80 lbs of coarse-grade salt and 5 gallons of tap water into the brine tank.
- Powering On the Control Valve: Plug the power supply into a 120-volt outlet and connect the power line to the control valve. The screen should light up.
- Flushing and Testing the Plumbing Lines: Place the unit in the bypass position. Locate the nearest faucet, remove the aerator (if present), and turn on the cold water. Slowly turn on the main water supply. Allow water to run for a few minutes until the system is free of air or foreign material and runs clear.

System Initialization
After installation, the system needs to be initialized and programmed. Familiarize yourself with the digital display and control buttons. The system is not ready for service until the startup procedure, detailed in the owner's manual, is completed. This typically involves setting the time, regeneration mode, and water hardness levels.

Operating Instructions
The Aquasure Harmony water softener operates automatically once initialized. The digital control head manages regeneration cycles based on your programmed settings or water usage. You can monitor the system's status, including time of day, current flow rate, totalizer, and volume/days until the next regeneration, directly from the backlit display.
- Regeneration Modes: The system supports Time Clock Delayed Control, Meter Immediate Control, and Meter Delayed Control. Select the mode that best suits your household's water consumption patterns.
- One-Push Regeneration: For immediate regeneration, press the designated button on the control head. This initiates a regeneration cycle to rinse out hardness.
- Bypass Valve: The bypass valve allows you to temporarily bypass the softener, providing untreated water to your home for tasks where softened water is not required.
Maintenance
Regular maintenance ensures the longevity and efficiency of your Aquasure Harmony water softener.
- Salt Refilling: Periodically check the salt level in the brine tank. Refill with coarse-grade water softener salt as needed to maintain optimal performance. The frequency depends on your water usage and hardness levels.
- System Cleaning: Keep the exterior of the unit clean. Avoid using harsh chemicals that could damage the components.
- Filter Replacement: If your system includes a pre-filter, ensure it is replaced according to the manufacturer's recommendations to prevent sediment buildup and protect the softener.
