5. Installation Guide

This system is designed for easy under-sink installation. No professional plumber is typically required. Ensure you have basic tools like a drill (if needed), adjustable wrench, and a bucket.

5.1. Pre-Installation Checklist

• Confirm all package contents are present.
• Identify a suitable location under your sink for the main unit, ensuring enough space for filter changes.
• Locate a power outlet for the UV-C faucet.
• Ensure your sink has an existing hole (e.g., for a soap dispenser) or is suitable for drilling a 1-inch hole for the faucet.

5.2. Step-by-Step Installation

1. Turn off Water Supply: Locate the cold water shut-off valve under your sink and turn it off. Open your kitchen faucet to relieve pressure.
2. Install Faucet:
   • If no existing hole, drill a 1-inch (25mm) hole in your countertop or sink.
   • Insert the UV-C faucet stem through the hole.
   • Secure the faucet from underneath the sink using the provided washer and nut.

3. Connect Water Inlet:
   • Disconnect the cold water line from your existing faucet.
   • Install the provided water inlet adapter (T-valve) to the cold water supply line. Use Teflon tape on threaded connections to prevent leaks.
   • Reconnect your existing faucet's cold water line to the adapter.
   • Connect one end of the water tubing to the adapter's filtered water outlet.
4. Connect to Main Unit:
   • Connect the other end of the water tubing from the inlet adapter to the "IN" port on the LCF main unit.
   • Connect another piece of water tubing from the "OUT" port on the LCF main unit to the inlet on the UV-C faucet.
5. Install Filters: Ensure the PPC, CTO, and UF filters are correctly inserted into their respective slots in the main unit. They are typically labeled. Twist and pull to secure or remove.
6. Power Connection:
   • Insert the 2 AAA batteries into the battery compartment for the filter life reminder.
   • Connect the power adapter to the UV-C faucet and plug it into a standard electrical outlet.
7. Restore Water Supply & Check for Leaks: Slowly turn on the cold water supply valve. Check all connections for leaks. Tighten any leaking connections.
8. Flush the System: Open the LCF UV-C faucet and let water run for at least 10-15 minutes to flush out air and carbon fines. The water may appear cloudy initially; this is normal.

6. Operating Instructions

Using your LCF water filter system is straightforward.

6.1. Dispensing Filtered Water

• To dispense filtered water, simply turn the handle on the UV-C faucet.
