Setup and Installation
The ECOP20 system is designed for quick and easy DIY installation under your sink. No professional help is typically needed.
Pre-Installation Checklist:
- Ensure you have adequate space under your sink for the filter unit and faucet.
- Confirm access to your 3/8" cold water line.
- Gather basic tools: adjustable wrench, drill, screwdriver, utility knife.
Installation Steps:
- Turn off Water Supply: Locate and turn off the cold water supply valve under your sink.
- Install Faucet: Drill a hole in your sink or countertop (if not already present) for the dedicated filtered water faucet. Secure the faucet according to the instructions provided in the detailed manual.
- Connect to Cold Water Line: Use the provided connectors to tap into your existing 3/8" cold water line.
- Mount Filter Unit: Securely mount the filter head unit under the sink in a convenient location.
- Connect Tubing: Utilize the color-coded tubing and push-in connectors to link the cold water supply to the filter unit, and the filter unit to the new filtered water faucet. Ensure all connections are secure to prevent leaks.
- Install Filters: Insert the two filter cartridges into their respective housings on the filter unit. Twist them into place until secure.
- Flush System: Slowly turn on the cold water supply. Open the filtered water faucet and allow water to run for several minutes to flush out any air and carbon fines. Check for leaks.

Operating Instructions
Once installed, operating your EcoPure ECOP20 system is straightforward:
- Accessing Filtered Water: Use the dedicated chrome faucet to dispense filtered water for drinking, cooking, and other needs.
- Initial Use: After installation or filter replacement, run water through the filtered faucet for at least 5 minutes to ensure proper flushing and to remove any air from the system.
- Water Flow: The system is designed to provide a steady flow of filtered water. If you notice a significant reduction in flow, it may indicate that the filters are nearing the end of their lifespan and require replacement.

Maintenance: Filter Replacement
Regular filter replacement is crucial for maintaining the performance and water quality of your EcoPure ECOP20 system. The encapsulated filters are designed for quick and mess-free changes.
When to Replace Filters:
- Filters should typically be replaced every six months, or sooner if you notice a decrease in water flow or a change in water taste/odor.
- Refer to the filter life indicator on your faucet (if applicable) or your installation date for guidance.
Filter Replacement Steps:
- No Water Shutoff Needed: The design allows for filter changes without needing to turn off the main water supply.
- Twist Off Old Filters: Grasp the old filter cartridge and twist it counter-clockwise to remove it from the filter head.
- Insert New Filters: Align the new filter cartridge with the filter head and twist it clockwise until it clicks securely into place.
- Flush System: Run water through the filtered faucet for a few minutes to flush the new filters and remove any air.
No tools are required, and there is no messy handling of dirty filters.
