Installation Tips

How to Use the Quick-Connect Fittings:

To connect: Push the tubing into the fitting until you reach the mark on the tubing. If the tubing is not fully inserted, no seal will be created and leakage will occur. When the tubing is fully inserted, put the blue lock clip on the fitting. It will lock the tubing in place and prevent it from falling off.

If the tubing is too long, cut it to a suitable length with a sharp utility knife or scissors. Cut the tubing squarely and cleanly. Make sure the tubing is fully inserted (about 0.8").

To disconnect: Remove the blue lock clip from the fitting. Use your thumb and index finger to press down the lock sleeve. Use your other hand to pull out the tubing from the fitting. Do not pull out the tubing directly, as this will damage the fitting and cause leakage.

How to Drill a Hole into Your Sink or Countertop (Optional):

Confirm if there is an existing hole available to install the RO faucet. If not, drill a hole referring to the instructions. It's highly recommended to watch the YouTube video "How to Drill a Faucet Hole" for a better understanding. Wear safety glasses to protect your eyes while drilling the faucet hole.

1. Choose a diamond core bit for granite, and a carbide drill bit for stainless steel. Do not use a hammer drill on natural stone, glass or ceramic.

2. Glue the sticker on your sink or countertop, and drill a hole referring to the sticker hole size (1").

3. Make an indent with a center punch on a stainless-steel sink before drilling to help guide the bit.

4. Be careful when drilling on a porcelain sink, as it can be easily chipped. Apply downward pressure firmly on the bit until you break through the surface.

5. Start at the lowest speed, and hold the drill straight with firm pressure to prevent the bit from walking on the counter.

6. Once you break through the surface, swirl the drill a little to apply pressure in a circle evenly.

Installation Steps

Prior to installation, it is highly recommended to watch the video "Waterdrop G3 RO Installation" on YouTube.

NOTES:

• The RO system must be connected to the COLD water supply ONLY.
• Do not install the system in exposure to direct sunlight or harmful chemicals, nor any place where it may be damaged.
• Do not install the system near any heat source.
• Do not install the system outdoors.

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

The "INPUT" water tubing has been attached to the feed water adapter for easy installation.

1. Shut off the water supply. Turn on the kitchen faucet to release the water pressure. Make sure the water has stopped before proceeding. Get a towel or bucket to catch any excess water.
2. Disconnect the cold water pipe from the cold water supply valve.
3. Twist the feed water adapter onto the cold water supply valve (with its washer) and tighten it with an adjustable wrench. If the cold water pipe is 1/2", unscrew the two converters from the feed water adapter first.
4. Twist the cold water pipe (with its washer) onto the feed water adapter and tighten with an adjustable wrench.

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

If your kitchen sink or countertop does not have an existing hole, you will have to drill one (1"). Refer to Page 5.

1. Insert the faucet spout into the faucet body.
2. Insert the faucet stem, power cord and filtered water tubing into the hole on the countertop.
3. Under the sink, slip on the nut and tighten it up.

Step 3: Install the Drain Saddle

1. Paste the foam seal onto the front plate of the drain saddle. Ensure the hole of the foam seal is aligned with the hole of the front panel. Choose a spot on the drain pipe that is convenient for installing the drain saddle. It's recommended to install the drain saddle on the vertical drain pipe.
2. Drill a 1/4" hole in the drain pipe. Be sure not to penetrate the opposite side of the pipe.
3. Slip the front plate on one end of the tubing (without the mark), and insert the tubing into the drilled hole for about 0.6".
4. Position the back plate on the drain pipe by tightening the screws and nuts evenly while leaving the tubing in the hole.
5. Pop the lock clip on the fitting to secure the connection. In some cases, the "WASTE" water tubing needs to be connected to the drainpipe through an air gap. Consumers need to purchase air gap accessories additionally.

Step 4: Position the RO System Housing

It is not recommended to place the housing against the cabinet, as there may be vibrations when the system works. The power-supply receptacle for the appliance shall be installed in a cabinet or on a wall adjacent to the undercounter space in which the appliance is to be installed. There should be an opening through the partition between the compartments large enough for the attachment plug to pass through. The longest dimension of the opening shall not be more than 1.5" (38 mm). If the partition is wood, the edges of the opening should be smooth and rounded. If the partition is metal, it should be covered with an edge protector. Care should be exercised when the appliance is installed or removed to reduce the likelihood of damage to the power cord.

The system housing dimensions are approximately 18.12" (height) x 5.67" (width) x 17.72" (depth).

Step 5: Connect Tubing

Confirm the tubing length you need first, and then cut the tubing if it's too long, referring to "How to Use the Quick-Connect Fittings" on page 4.

1. Install the "INPUT" Water Tubing: Remove the plug from the "INPUT" water port. Identify the white 3/8" PE tubing which has been attached to the feed water adapter. Insert the other end of the tubing into the "INPUT" water port and pop the lock clip on the fitting.
2. Install the "FILTERED" Water Tubing: Remove the plug from the "FILTERED" water port. Identify the white 1/4" PE tubing that is pre-installed with the RO faucet. Insert the other end of the tubing into the "FILTERED" water port and pop the lock clip on the fitting. Make sure it is fully inserted until you reach the mark on the tubing.
3. Install the "WASTE" Water Tubing: Remove the plug from the "WASTE" water port. Identify the red 1/4" PE tubing which has been attached to the drain saddle. Insert the other end of the tubing into the "WASTE" water port and pop the lock clip onto the fitting. Make sure it is fully inserted until you reach the mark on the tubing.

Step 6: Connect Power Cord

Connect the RO faucet to the system: Insert the power cord which is attached to the RO faucet into the "FAUCET" connector at the back of the housing, and tighten the nut. Connect Power Adapter: Insert the DC head of the power adapter into the "POWER" port at the back of the housing. Do not connect the power socket yet.

Step 7: Install the Filters

Each filter is marked with a logo (CB/CF/RO) and an installation arrow.

1. Remove the wrapping and protective cap from the filter.
2. Insert the filter into its corresponding hole, align the arrow with the empty circle on the housing.
3. Twist the filter with a little force forward in a clockwise direction for 90 degrees, until the arrow is aligned with the solid circle on the housing. You may hear a clicking sound when the filter is fitted into place properly.
4. Repeat the above steps to install the other two filters.

Step 8: Start up the System

1. Turn on the cold water supply valve. Check for leaks.
2. Insert the plug of the power adapter into the socket. If the system cannot be powered on, check the power under the sink, the connection between the plug and the power outlet, and ensure the system has been plugged correctly into the power outlet. Try another power outlet if necessary. Contact customer service if the system still cannot be powered on.
3. The system starts flushing automatically for 5 minutes. The filter life indicators on the front panel will flash blue, yellow, and red in turn, then turn blue for 5 minutes. The front screen displays flushing status. The faucet filter life indicator will flash white, yellow, red in turn for 1 second, then turn white for 5 minutes. The faucet displays flushing status and the outer ring light will flash clockwise dynamically. Do not turn on the RO faucet. Allow the system to flush automatically for 5 minutes. The three indicator lights will be off when the flush is complete. A slow water flow is normal if the RO faucet is turned on, and water is not drinkable during the automatic flush.
4. Turn on the RO faucet. Allow it to run for 30 minutes until the front panel screen and faucet screen start displaying a TDS reading. Be sure to carefully check the tightness of each part of the system while flushing. Check and ensure all tubing is installed correctly and completely. Make sure there are no leaks at the joints, fittings, valves, and tubing connections. The water is not drinkable during the flushing. The 30 minutes are accumulative. If the flush is stopped in advance, the system will continue to flush when you open the RO faucet again until it reaches 30 minutes.
5. Confirm the flush is completed before turning off the RO faucet and ensure it's not leaking.
6. Please fix the power adapter with the cable tie so that it does not move by impact. To avoid failure, stay away from any water sources, including pipe fittings, the bottom of the basement, and wet floors.

Congratulations! You have successfully installed the system!

Owner's Manual

Display and Operation

Section 1: TDS Display

The built-in TDS sensor detects the water quality when the system begins to work, and shows the TDS reading on the front panel display screen and faucet screen. The system will provide above a 90% TDS rejection rate when working properly, which may vary with a deviation of 10% depending on the source water quality and water usage. The TDS reading may vary as the water is flowing. The TDS display on the front panel screen will go off after 5 minutes when the system stops dispensing water. The TDS display on the RO faucet screen will go off after 1 minute when the system stops dispensing water. During the first 10-30 seconds of water dispensing, the system is updating the TDS reading and there is residual water in the filtered water tubing. Therefore, the actual TDS value will be higher than the TDS reading on the screen. Please note that the reading in the figure is only used as an example, and the actual reading may vary according to different water conditions.

Section 2: Filter Life Reminder

Filter life may vary depending on source water quality and water usage. Please replace the filter according to the reminder of the filter life indicators.

1. Filter Life Indicator on System Housing: There are helpful electronic filter indicators (CF/CB/RO) on the front panel that will notify you to perform a routine filter replacement by color change. Be sure to reset the filter life indicator every time you replace your filter.

Filter Life:

• Activated Carbon Filter (CB): Up to 12 months or 1,100 gallons
• Pre-sediment and Carbon Block Filter (CF): Up to 6 months or 550 gallons
• Reverse Osmosis Membrane Filter (RO): Up to 24 months or 2,200 gallons

Display Status:

NOTE: The indicators will notify you according to the usage time or processing capacity of the filters, whichever comes first.

Visual indicators show filter status: Blue (Good), Yellow (Replace Soon), Red (Replace Now).

2. Filter Life Indicator on the RO Faucet: Different light colors displayed on RO faucet indicate different filter life status.

Faucet Screen Status:

Section 3: Filter Replacement Guide

If the filter expires, please purchase and replace the filter immediately. Otherwise, the filtration efficiency will decrease significantly and affect the performance.

How to Replace Filters: The filters can be replaced directly without cutting off the power and water supplies, and there will be no water and electric leakage.

1. Before removing the filter, please turn off the faucet first and wait for 30s to fully release the internal pressure of the RO system, which makes the filter easier to remove and install.
2. Twist off the filter that needs to be replaced in a counterclockwise direction. After replacing the CF and CB filter, it's recommended to press the center knob protruding at the top of the old RO filter to release the pressure to avoid water spills. Get a towel or bucket to catch any excess water.
3. Twist the new filter into the housing in a clockwise direction.
4. Reset the filter life indicator and flush the filter after replacement (please refer to the following steps).

How to Reset the Filter Life Indicator: Hold the CB filter life indicator for 7 seconds until the system beeps. Refer to the same method for CF or RO indicators.

How to Flush the Filter after Replacement:

• For CF filter: It will be flushed automatically for 5 minutes without turning on the RO faucet.
• For CB filter: Turn on the RO faucet to flush for 15 minutes.
• For RO filter: Turn on the RO faucet to flush for 30 minutes.

Section 4: Automatic Flushing

The system will be flushed automatically in one of the following situations:

1. Flush for Accumulative Working Time over 2 Hours: To maintain and extend the life expectancy of the filters, the system will be automatically flushed for 20 seconds after working for two hours. While flushing, the front panel screen will show a display similar to what is shown in Figure 30. If the user decides to take water during the flushing, the system will quit flushing and switch to dispensing.
2. Flush for Power Restore: When power is restored after a blackout, the system will be forced to be flushed automatically for 20 seconds. While flushing, the front panel screen will display as seen in Figure 30. The blue, yellow, and red lights will flash in turn for one second, and then the blue light will be on for 20 seconds. The indicators will be off when the flushing is complete.
3. Recycled Fresh Water Flushing: Recycled fresh water flushing function is to ensure each cup of water to be fresh and healthy. The system will automatically recycle fresh water and start flushing after it has dispensed water over 5 minutes. When the system is recycling fresh water and subjected to flushing, the panel displays as shown in Figure 30.

Section 5: Malfunction Display

When the system is in fault, the malfunction indicates as follows:

• E02: For inside water leakage: The buzzer keeps beeping. Please pull out the water container at the back and check if there's any water. If there is, clean the container and re-install it back. The malfunction should be fixed automatically. If E02 shows again shortly, please contact the customer service hotline 1-888-352-3558 or send an email to service@waterdropfilter.com for assistance.
• E03: If the booster pump overworks: The buzzer beeps for 3 minutes. The system will need to be powered on again to recover.
• E04: If the booster pump starts and stops frequently: The buzzer sounds 5 times. The system will need to be powered on again to recover.

Refer to "Troubleshooting" for detailed solutions concerning malfunction code reminders.

System Maintenance

• If you don't use the system for more than one week, turn on the RO faucet, shut off the cold water valve, and disconnect the power. Seal the filters and store them in the refrigerator (not the freezer). You need to open the RO faucet and allow it to run for 10 minutes first before using the system again. Otherwise, you need to replace the filters, as bacteria may grow when the system is not used for a long time.
• Please replace the filter regularly according to the filter life indicator. While the testing was performed under standard laboratory conditions, actual performance may vary depending on the source water quality and water usage. In case of early blockage and failure of the filters, it's recommended to replace the filter in accordance with the actual usage.
• Clean the system with clear water. Do not spray the water directly. Do not use steel wool, an abrasive cleaner or corrosive liquid such as gasoline or acetone.
• When cleaning, do not pour other liquids into the filter to avoid damage to the filter system.
• Keep the waste water pipe unobstructed to avoid damage to the filter or internal components.
• When the drain pipe is blocked, do not use the system (please turn off the power) to avoid waste water from soaking the floor.
• Check the system and water pipe fittings regularly for water leakage to avoid any property damage.
• Regularly check whether the power supply and wires are damaged or loose to avoid major accidents caused by electric leakage.
• If you are using well water as the source, please ensure that the feed water has been through a pre-filtration system. Otherwise, large particles in the well water will easily clog the filter and shorten the filter life.

Troubleshooting

If the System Cannot Be Powered on After You Insert the Plug of Power Adapter:

Check the power under the sink, as this mostly occurs when the power under the sink is off. Also, check the connection between the plug and the power outlet, and ensure that the system has been plugged correctly into the power outlet, as this may occur in a few cases. To test if there is a problem with the system itself, just pick up the system and try another power outlet. Please contact us if the system can't be powered on. We will help you figure it out.

No Output Water from RO Faucet:

• Filter expired. Check the filter life indicators to confirm which filter needs to be replaced and replace it immediately.
• Low water pressure. Check and confirm the water pressure is between 14.5 PSI and 87 PSI.
• Water supply is off. Turn on the feed water adapter or water supply valve.
• Incorrect filter installation. Re-install the three filters, and make sure they are fitted properly.
• Tubing is crimped. Check all tubing and remove any crimps.

Low Water Flow at the RO Faucet:

• Leak from tubing connection. Check and ensure all tubing is installed correctly and completely.
• Filter expires. Check the filter life indicators to confirm which filter needs to be replaced and replace it immediately.
• Low water temperature. Be sure to use the system at a temperature of 41-100 °F.
• Use well water as the source and the feed water has not been through a pre-filtration system, the filter has been clogged. If you are using well water as the source, please ensure that the feed water has been through a pre-filtration system. Otherwise, large particles in the well water will easily clog the filter and shorten the filter life.

Water Leakage:

• Check all joints, fittings and tubing connections to locate the leakage. Make sure the filters are well installed.
• If the front panel screen and faucet screen show the code E02, which means there is water leakage inside the system, please pull out the water container at the back and check if there's any water. If there is, clean the container and re-install it. The malfunction should be fixed automatically. If E02 shows again shortly, please contact the customer service hotline 1-888-352-3558 or send an email to service@waterdropfilter.com for assistance.

No Display on the System:

• To save power, the faucet screen will go off after 1 minute when the system stops dispensing water, and the front panel screen will go off after 5 minutes when the system stops making water.
• No power or power adapter is broken. Check and make sure the power adapter is plugged in. Change a new power adapter if it is broken.

High TDS in Filtered Water:

The system will provide a 90%+ TDS rejection rate (tested under standard laboratory conditions) after full flushing when working properly. If the TDS reading is high, the following are possible causes:

• The system hasn't been used for a long time. Open the RO faucet, allow it to run for a while. The TDS reading will return to normal.
• The RO filter expired. Replace the RO filter immediately.
• The waste water pipe may be crimped or clogged. Check and remove crimps. Re-align the drain saddle and drainpipe.
• The source water may have a high TDS. Test the source water and filtered water. The filtered water's TDS shall be about 5%-10% of your source water's TDS. This is a normal range. If there is a high TDS in the source water, it may reduce the service life of the system. When the filtered water's TDS creeps up to 15%-20% of the source water's TDS, please perform routine filter replacement.

TDS Reading Fluctuates When Dispensing Water:

• The TDS reading displayed is the TDS of the flowing filtered water. Therefore, the content of the dissolved solids may vary slightly as the water flows, causing the fluctuation of the TDS reading.
• The built-in TDS sensor has deviation, causing the fluctuation of the TDS reading.

The Difference between the TDS Reading Tested by the TDS Meter and the Displayed Reading:

• The reading tested by the TDS Meter is the TDS of static water in the container while the TDS reading displayed by the system is the TDS of flowing water. As a result, the TDS readings are different.
• There are errors in the TDS Meter tests.

Filtered Water from the RO Faucet Tastes Like Tap Water:

• Incorrect tubing installation. Make sure the waste water tubing is not connected with RO faucet.
• The filters are not well-installed. Make sure the filters are placed properly.
• Filter expires. Check the filter life indicators to confirm which filter needs to be replaced and replace immediately.

Booster Pump Overworked Reminder:

The front panel screen and RO faucet screen show code E03. The buzzer keeps beeping for 3 minutes.

• Continuously dispensing water for more than 30 minutes. Power on the system again to recover.
• There is a leak at the tubing connection between the system and the RO faucet. Turn off the power. Check the tubing connection, make sure the tubing is inserted into the quick-connect fitting properly and firmly, and power on the system again.

Booster Pump Starting and Stopping Frequently Reminder:

The front panel screen and RO faucet screen show code E04. The buzzer sounds 5 times.

• There is an internal pressure imbalance. Disconnect the power. Turn on or turn off the RO faucet completely and remove all tubing crimps. Make sure the faucet is not blocked and power on the system again.

Loud Sound of RO System:

The sound will not exceed 65 dB, which makes no difference to everyday lives (65 dB is tested under standard laboratory conditions, where the feed water pressure is between 14.5 PSI and 87 PSI). A loud sound may be caused by the following reasons:

• The system is not positioned in a flat area. Make sure the system is placed smoothly without shaking.
• The system is placed against the cabinet. Do not place the system against the cabinet. The system may vibrate when it works.
• The water pressure is unstable. Check and confirm the water pressure is between 14.5 PSI and 87 PSI. The sound will decrease when the water pressure becomes stable.
