The ISPRING WCB320 has the following specifications:

The ISPRING WCB320 uses the following filter stages:

You will need the following tools to install the ISPRING WCB320:

Safety Glasses, Towels, Flat Head Screwdriver, Deburring Tools, Pipe Cutter, Torch, Adjustable Wrench, Medium Crescent Wrench, and Plumber’s Tape.

Step 1: Determine the location and water flow direction. Measure, cut, and remove the section of water line where the system is to be installed. Allow the line to drain and smooth the cut ends with a deburring tool.

Step 2: Securely mount the ISPRING WCB320 filter bracket to a wall, ensuring it is level. Attach plumbing to the inlet and outlet using 3/4 inch male NPT threaded adapters, applying 12 to 15 wraps of plumber’s tape to each.

Step 3: Add optional shutoff valves or pressure gauges on either side of the filter. Fit pipe unions, shutoff valves, and nipples as needed to connect to the main water line.

Step 4: If you have metal pipes, connect a ground jumper wire to the ISPRING WCB320 system.

Step 5: Unwrap the cartridges and insert them into each housing, centering them on the standpipe. Ensure the center knob of the housing fits securely into the filter’s central hole. Hand tighten the housing, then use the supplied filter wrench to lightly turn, taking care not to over-tighten.

Step 6: Slowly turn on the water supply to fill the housing. Check for leaks. Open the nearest cold water faucet and run water for about 10 minutes to expel carbon fines. Do not use a hot water faucet for this initial flush.

To replace cartridges in the ISPRING WCB320:

1. Turn off the water supply and open a nearby faucet to drain the system. Use the filter wrench to unscrew the housing.

2. Locate and remove the O-ring using a small, clean flat head screwdriver. Set it aside.

3. Remove and discard the old filter cartridge.

4. Scrub the housing and cap with warm water mixed with about 2 tablespoons of household bleach. Rinse all parts thoroughly.

5. If necessary, lubricate the O-ring with clean silicone grease. Do not use petroleum jelly. Insert the O-ring into the groove and ensure it is seated correctly.

6. Insert the new cartridge, ensuring it slips over the standpipe. Align the bottom of the housing into the cap and hand tighten, then use the wrench to fit it snugly. Do not over-tighten.

7. Turn the water on slowly and check for leaks. Finally, run a few cold-water faucets to flush the system of air and carbon.

If water pressure drops over time, the cartridges may need replacement. It is recommended to replace them every 6 to 12 months. If pressure drops immediately after installing the ISPRING WCB320, check that the plastic wrapping was removed from the cartridges. Additionally, avoid high-flow situations for the first 72 hours, as this can cause temporary carbon blockage; if this occurs, turn off all water for at least 10 minutes and then resume using water at low or normal flow rates.

Yes, if your source water has a high level of hardness, a water softener is still needed. While the ISPRING WCB320 can remove sediment, chlorine, and rust, it does not soften the water. Hard water can reduce the lifespan of the filter cartridges in the ISPRING WCB320.
