Installation Guide

Follow these steps to install your Waterdrop DLB Under Sink Water Filter System. A video guide is also available below for visual assistance.

Step 1: Connect the Water Supply (Cold Water Only)

1. Connect the inlet tubing to the filter base marked with "IN". Note: When the hose is fully inserted, there will be a 1/8-inch gap between the hose and the filter base. This design allows for easy replacement and does not affect the sealing performance. To remove the hose, press and pull.
2. Shut off the water supply, then turn on the kitchen faucet to release the water pressure.
3. Disconnect the cold-water pipe from the cold-water supply valve.
4. Twist the feed water adapter onto the cold water supply valve (with its washer) and tighten it with an adjustable wrench.
5. Twist the cold-water pipe (with the washer) onto the feed water adapter and tighten it with an adjustable wrench.

Step 2: Install the Stainless Steel Faucet

1. Insert the faucet spout into the faucet body.
2. Insert the faucet stem into the hole on the countertop. Note: If your kitchen sink or countertop has no pre-drilled hole, you will need to drill a one-inch hole or use the existing hole for a soap dispenser.
3. Under the sink, slide on the other parts as shown in the video.
4. Firmly insert the quick-connect fitting into the faucet stem.
5. Connect one end of the outlet tubing to the faucet's quick-connect fitting, then secure it with the clip.
6. Connect the other end to the outlet tubing of the filter head marked "OUT". Push the tubing into the fitting until it reaches the marked line.

Step 3: Activate the Filter Life Indicator

1. Place the main unit on a flat, clean, and dry surface under the cabinet to ensure the suction cups on the bottom adhere securely.
2. Press and hold the left or right button for five seconds until the system beeps, activating the indicator.

Step 4: Check for Leaks and Flush the Filter

Turn on the water supply. Flush the replacement filter for 10 minutes before use.

Leakage Notes:

• In the event of water leakage, turn off the water supply.
• If the leakage occurs at position 1 (feed water adapter connection), wrap Teflon tape around the external thread.
• If the leakage occurs at positions 2, 3, or 4 (tubing connections), check whether the tubing is fully inserted into the fittings. If not, push it in again until it reaches the mark on the tubing.

Operating Instructions

The Waterdrop DLB system offers convenient access to both filtered and unfiltered water.

Switching Between Tap & Purified Water:

The system includes an extra faucet dedicated to purified water. Use your main kitchen faucet for washing dishes, fruits, and vegetables with unfiltered tap water. For purer drinking water and tastier meals, use the separate pure faucet. This helps extend the life of your filter cartridges.

The system is designed for rapid water flow, providing pure water quickly for various needs:

• 2 Seconds: For 6oz of pure hydration.
• 3 Seconds: For 8oz of water for aromatic tea.
• 17 Seconds: For 48oz of fresh water for soup.

3. Take out the new filter and remove the protective cap.
4. Turn the new filter a quarter turn to the left to install it.
5. Briefly press the button to light up the indicator, then hold it for 5 seconds until the system beeps three times to complete the reset.
