Installation Instructions

Before Installation

Inspect the Package

Open the box and inspect all components and quick-connect fittings against the parts list. Contact Waterdrop at 1-888-352-3558 or waterdropfilter.com if any parts are cracked or broken.

Required Tools

• Variable speed drill
• Drill bit: 1/4" (for drainpipe), 1" (for faucet hole)
• Adjustable wrench, pliers
• Screwdriver
• Utility knife or scissors
• Flashlight
• Towel

Specifications

NOTE: The daily production rate is measured under 30 psi dynamic feed water pressure and 77 "F water temperature. If using well water, ensure it has a pre-filtration system.

Installation Steps

It is highly recommended to watch the video "Waterdrop G2 undersink RO installation" on YouTube ▶️.

General Notes:

• Connect to COLD water supply ONLY.
• Do not install in direct sunlight, near harmful chemicals, heat sources, or outdoors.

Step 1: Install the Feed Water Adapter (3/8" or 1/2")

Ensure water supply is shut off and pressure is released. Disconnect the cold water pipe from the valve and attach the feed water adapter. If the cold water pipe is 1/2", unscrew converters first.

Diagram Description (Figure 3 & 4): Shows connecting the feed water adapter to the cold water supply valve and then connecting the cold water pipe to the adapter. Illustrates unscrewing converters for a 1/2" pipe.

Step 2: Install the RO Faucet (Non-Air Gap Faucet)

If no hole is available, drill a 1" hole or use the soap dispenser hole (refer to Page 5 for drilling instructions). Insert the faucet spout into the body, then the stem into the countertop hole. Secure parts under the sink and attach the quick-connect fitting to the faucet stem.

Diagram Description (Figure 5): Illustrates installing the RO faucet body, stem, mounting washer, nut, and quick-connect fitting under the sink.

Step 3: Install the Drain Saddle

Choose a convenient spot on the drainpipe and drill a 1/4" hole, avoiding the opposite side. Install the drain saddle on the vertical drainpipe. Connect the waste water tubing to the saddle, ensuring it's inserted about 0.6". Secure with screws and a lock clip.

Diagram Description (Figure 6, 7, 8): Shows the front and back plates of the drain saddle, inserting tubing into the drilled hole, and securing the saddle.

NOTE: In some areas, waste water tubing requires an air gap connection (additional accessories may be needed).

Step 4: Position the RO System Housing

Ensure sufficient space under the countertop. A power outlet must be accessible. Avoid placing the housing directly against the cabinet to prevent vibration noise.

Diagram Description (Figure 9): Shows the dimensions of the RO system housing (14" height, 17.3" length, 5.9" width) and its placement under the countertop.

Step 5: Connect Tubing

Refer to "How to Use the Quick-Connect Fittings" on page 4 for detailed instructions.

• Input Water Tubing: Connect from the feed water adapter to the "IN" water port on the system. Ensure full insertion to the mark.
• Filtered Water Tubing: Connect from the RO faucet to the "F" filtered water port on the system. Ensure full insertion to the mark.
• Waste Water Tubing: Connect from the drain saddle to the "W" waste water port on the system. Ensure full insertion to the mark.

Diagram Description: Illustrates the connection points for input, filtered, and waste water tubing using quick-connect fittings and lock clips.

Step 6: Start up the System

1. Turn on the cold water supply valve and check for leaks.
2. Insert the power plug. If the system doesn't power on, check power sources and connections.
3. The system will beep, and filter life indicators will flash blue, purple, and red before turning solid blue for 3 seconds.
4. Turn on the RO faucet and let water run for 30 minutes for flushing. The filtering indicator should change from flashing to permanent blue. Check all connections for leaks during flushing. Note: Water is undrinkable during this 30-minute flush.
5. Confirm flushing is complete and the faucet doesn't leak.
6. Secure the power adapter with a cable tie to prevent movement. Keep away from water sources.

Owner's Manual

Display and Operation

Section 1: Working Mode Display

When making water, filter and power indicators are solid blue (Figure 11). Filter life indicators show real-time status and color. The filtering indicator turns off when the system stops making water (Figure 12).

Diagram Description (Figure 11 & 12): Shows the RO system front panel with indicator lights in different states.

Section 2: Filter Life Reminder

Electronic filter indicators (CF/MRO) on the front panel notify you of filter replacement needs via color change. Reset the indicator after each filter replacement.

NOTE: Indicators alert based on usage time or capacity, whichever comes first. Filter life may vary based on water quality and usage.

Diagram Description: Shows indicator lights for "Good" (Blue), "Replace Soon" (Purple), and "Replace Now" (Red).

Section 3: Filter Replacement Guide

Replace filters immediately if expired to maintain filtration efficiency. Filters can be replaced without shutting off power or water.

1. Twist the filter counterclockwise to remove it (Figure 13). Hold the filter body while twisting.
2. Remove wrappings and protective cap from the new filter.
3. Insert the new filter, aligning the arrow with the empty circle on the housing.
4. Twist clockwise for 90 degrees until the arrow aligns with the solid circle. You should hear a click.
5. Repeat for the other filter.
6. Reset the filter life indicator and flush the filter after replacement.

Diagram Description (Figure 13): Illustrates twisting a filter to remove it from the housing.

How to Reset the Filter Life Indicator

1. Press the filter life reset indicator for 5 seconds until you hear a beep.
2. Press the reset indicator again to choose the CF or MRO filter (if only one expired, no choice needed). The indicator will flash.
3. Press the reset indicator for another 5 seconds. Reset is complete when you hear a beep, and the indicator turns solid blue.

NOTE: If the indicator starts flashing and there's no operation for 10 seconds, resetting stops.

Diagram Description (Figure 14): Shows a hand pressing the filter life reset indicator on the system's front panel.

Section 4: Malfunction Display

• Overworked Reminder: If the system runs for over 30 minutes continuously, it will beep for 3 minutes, stop making water, and indicators may flash red. Power cycle to recover.
• Starting and Stopping Frequently Reminder: If the booster pump cycles frequently within 20 minutes, the system stops, and indicators may flash purple. Power cycle to recover.

System Maintenance

• If not used for over 1 week, flush the faucet before reuse.
• Replace filters regularly based on indicators.
• Clean the system with clear water. Do not use abrasive cleaners or corrosive liquids.
• Do not pour other liquids into the filter.
• Keep the waste water pipe unobstructed.
• If the drainpipe is blocked, turn off the system to prevent flooding.
• Regularly check for water leaks and damaged wires.
• If using well water, ensure it has pre-filtration to prevent clogging and extend filter life.

Troubleshooting

• System Cannot Be Powered On: Check power source, connections, and try another outlet. Contact Waterdrop if issues persist.
• No Output Water from RO Faucet: Check filter expiration, water pressure (14.5-87 psi), water supply valve, and filter installation. Ensure no tubing is crimped.
• Low Water Flow at RO Faucet: Check for crimped tubing or leaks. Check filter expiration. Ensure water temperature is 41-100 "F. If using well water, ensure pre-filtration.
• High TDS in Filtered Water: System may need flushing after long disuse. Check RO membrane filter expiration. Ensure waste water tubing is not crimped/clogged. Source water may have high TDS; compare filtered TDS (should be 5-10% of source TDS).
• Water Leakage: Check all joints, fittings, and tubing connections. Ensure filters are installed correctly.
• Filtered Water Tastes Like Tap Water: Check tubing installation (waste water tubing not connected to RO faucet). Check filter expiration.
• Booster Pump Overworked Reminder: If dispensing continuously for >30 mins, power cycle to recover. Check for leaks at tubing connections.
• Booster Pump Starting and Stopping Frequently Reminder: Check for internal pressure imbalance. Power cycle, remove tubing crimps, ensure faucet is not blocked.
• Loud Sound from the RO System: Ensure system is on a flat, stable surface. Do not place against cabinets. Check water pressure (14.5-87 psi).
