Installation Guide
The Vortopt Q1 system is designed for quick and easy installation, typically within 3 minutes, and fits standard US 3/8" and 1/2" cold water lines.
- Prepare the Installation Area: Turn off the cold water supply to your kitchen faucet. Clear the area under your sink where the filter will be installed.
- Connect to Cold Water Line: Disconnect the existing cold water line from your faucet. Use the provided metal braided hoses to connect the filter system to both the cold water supply valve and your kitchen faucet's cold water inlet. Ensure all connections are hand-tightened, then use a wrench for a quarter turn to secure, being careful not to overtighten.
- Mount the Filter (Optional): The compact design allows for placement under the sink. If desired, secure the filter unit to the cabinet wall using appropriate mounting hardware (not always included, check package).
- Rinse the Filter: Once installed, slowly turn on the cold water supply. Let water run through the filtered faucet for at least 5 minutes to flush out any carbon fines and air from the system. This ensures optimal performance and taste.

Maintenance
Filter Replacement:
The filter cartridge (PP+CTO) should be replaced every 9-12 months or after filtering 10,000 gallons, whichever comes first. Regular replacement ensures optimal filtration performance.
- Turn off Water Supply: Locate the cold water supply valve leading to the filter system and turn it off.
- Release Pressure: Open the filtered water faucet to release any residual pressure in the system.
- Twist and Unlock: The Vortopt Q1 features a twist-and-lock cartridge design. Gently twist the filter cartridge counter-clockwise to unlock it from the filter head.
- Remove Old Filter: Carefully pull down the old filter cartridge. Be prepared for a small amount of water to drip.
- Insert New Filter: Align the new filter cartridge with the filter head and push it upwards. Twist clockwise to lock it securely into place.
- Restore Water Supply & Flush: Slowly turn on the cold water supply. Open the filtered water faucet and let water run for 5 minutes to flush the new filter.
