3.2 Installation Steps
- Turn off Water Supply: Locate the main water shut-off valve for your system (e.g., whirlpool or hot tub) and turn it off completely.
- Relieve Pressure: Open a nearby faucet or valve to release any residual pressure in the system.
- Open Filter Housing: Use the appropriate wrench or tool to carefully open and remove the existing filter housing.
- Remove Old Filter: Extract the old filter cartridge and dispose of it properly.
- Clean Housing: Clean the inside of the filter housing, including the O-rings, to ensure a proper seal. Replace O-rings if they appear worn or damaged.
- Insert New Filter: Carefully insert the new KINETICO 5 Micron 10 inch Pleated Filter Cartridge into the housing. Ensure it is seated correctly and securely. The filter is 10 inches in length and designed for compatible housings.
- Close Housing: Hand-tighten the filter housing until snug, then use the wrench for an additional quarter to half turn. Do not overtighten.
- Restore Water Supply: Slowly turn on the main water supply valve. Check for any leaks around the filter housing.
- Flush System: Allow water to run through the system for a few minutes to flush out any air or loose carbon fines (if applicable to your system, though this is a pleated filter).

4. Operation
Once installed, the KINETICO 5 Micron 10 inch Pleated Filter Cartridge operates passively as water flows through your system. Its primary function is to remove suspended solids and particulate matter from the water.
- The 5-micron rating indicates the nominal particle size the filter is designed to capture.
- The pleated design provides a large surface area for efficient filtration and dirt-holding capacity.
- Monitor your water quality and system pressure. A noticeable drop in water flow or clarity may indicate that the filter is becoming clogged and requires replacement.
5. Maintenance
Regular replacement of the filter cartridge is crucial for maintaining optimal water quality and system performance.
