It shows the routing of inlet water tubing, hot water tubing, pure water tubing, and drain water tubing, along with the power connection.

Installation Tips

1. How to Use the Quick-Connect Fittings

To connect tubing:

Figure 1 shows a quick-connect fitting. Ensure the tubing is pushed into the fitting until it reaches the mark (approximately 0.8 inches) for a secure seal. Then, insert the blue lock clip to secure the tubing.

NOTE: If the tubing is not fully inserted, a seal will not be created, leading to leaks. If the tubing is too long, cut it squarely and cleanly with a utility knife or scissors, as shown in Figure 2.

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

If an existing hole is not available for the faucet, a new hole must be drilled. It is recommended to watch a tutorial video for this process. Wear safety glasses during drilling.

Steps:

1. Choose a suitable location for the faucet, ensuring enough space for the nut.
2. Use a diamond core bit for granite or a carbide drill bit for stainless steel. Avoid hammer drills on natural stone or glass.
3. Glue the provided sticker onto the sink or countertop and drill a hole matching the sticker's size (1 inch).
4. For stainless steel sinks, create an indent with a center punch before drilling to guide the bit.
5. Be cautious when drilling porcelain sinks to prevent chipping. Apply firm, steady downward pressure.
6. Start drilling at the lowest speed, keeping the drill straight. Once through the surface, swirl the drill slightly to ensure an even hole.

Figure 4 shows the placement of the hole on the sink edge, approximately 1.5 inches from the wall.

Disconnecting Tubing

To disconnect tubing from a fitting:

1. Remove the blue lock clip.
2. Press down the lock sleeve with your thumb and index finger.
3. Pull the tubing out with your other hand. (Figure 3)

NOTE: Do not pull the tubing directly, as this can damage the fitting and cause leaks.

Installation Steps

Before installation, select an accessible, flat area under the sink for the system. Ensure a grounded power outlet is available within reach.

WARNING: The system plug must be inserted into a grounding socket that complies with local codes and regulations. Do not share the power outlet with a garbage disposal. The system must be connected to the COLD water supply ONLY. Do not install the system in direct sunlight, near heat sources, outdoors, or in places where it may be damaged.

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

1. Shut off the water supply and open the kitchen faucet to release pressure. Catch any excess water with a towel or bucket.
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 with an adjustable wrench (Figure 5). The "INLET" water tubing is pre-attached.
4. If the cold water pipe is 1/2", unscrew the converters from the feed water adapter (Figure 6) before proceeding.
5. Twist the cold water pipe (with its washer) onto the feed water adapter and tighten with an adjustable wrench.

Step 2: Install the Smart Faucet

If no existing hole is present, drill a 1-inch hole (refer to Page 4). Insert the faucet stem, power cord, and filtered water tubing through the hole and into the decoration base. Under the sink, slide on the nut and tighten it (Figure 7). The faucet rotation angle is 120°.

Step 3: Install the Drain Saddle

1. Attach the foam seal to the front plate of the drain saddle, aligning the holes.
2. Choose a convenient spot on the drainpipe and drill a 1/4" hole, ensuring not to penetrate the opposite side (Figure 8). It is recommended to install on the vertical drainpipe.
3. Slip the front plate onto the tubing (without a mark) and insert it into the drilled hole for about 0.6" (Figure 9).
4. Position the back plate on the drainpipe and tighten screws and nuts evenly, keeping the tubing in place.

WARNING: To ensure smooth drainage, the drain water tubing must not touch the side wall of the drainpipe. Do not pull out the waste water tubing during boiling water to avoid scalding.

5. Pop the lock clip onto the fitting to secure the connection (Figure 10).

NOTE: In some areas, an air gap accessory may be required for connecting the drain tubing to the drainpipe.

Step 4: Position the System Housing

Ensure sufficient space under the countertop (6.7" *17.5" *16.6"). Allow 2 inches of clearance around the system. The power-supply receptacle should be in the cabinet or on an adjacent wall. An opening of no more than 1.5" is needed for the plug. Ensure edges of the opening are smooth. Position the front panel facing outwards for easy access to filters and indicators. The system should be placed horizontally, not tilted or on its side.

Step 5: Connect Tubing

Confirm tubing lengths and trim if necessary (refer to Quick-Connect Fittings section). Before connecting, remove plugs from water ports (Figure 12).

Connect tubing as follows (Figure 13):

• INLET water tubing (white) to the "INLET" port (white water port).
• "PURE" water tubing (blue) to the "PURE" port (blue water port).
• "HOT" water tubing (red) to the "HOT" port (red water port).
• "DRAIN" water tubing (gray) to the "DRAIN" port (gray water port).

Ensure tubing is fully inserted until it reaches the mark and the lock clip is engaged (Figure 14).

Step 6: Connect the Faucet Power Cord

Insert the faucet power cord into the "FAUCET" connector at the back of the housing and tighten the nut (Figure 15). Do not plug into the socket yet.

Step 7: Start up the System

1. Turn on the cold water valve and check for leaks.
2. Insert the system's power plug into a grounded socket.

WARNING: If the system does not power on, check the power plug and outlet. If the plug is live but the system still doesn't power on, contact customer service.

3. Flush for 60 seconds for first-time use. The system will automatically flush for 60 seconds, indicated by a countdown on the system and faucet displays.
4. Turn on the faucet and flush for 10 minutes by touching the cold water button (Figure 16) until no water outputs.
5. The system will automatically add water to the heating tank for 5 minutes until full. The system stops working automatically.

NOTE: Do not operate the faucet control panel during system flushing or water filling.

Step 8: Check Leakage

Carefully check all tubing connections, fittings, and valves for leaks. Congratulations on successfully installing the system!

System Maintenance

• Long-term storage: If the system is not used for a long time, turn off the water inlet valve, disconnect power, remove and seal the filter, and store it in a temperature above 32°F (0°C) to prevent freezing.
• First use after storage: Turn on cold water, run the system for 10 minutes to wash the filter. Then turn on hot water, run for 5 minutes, and discharge old water to prevent bacterial growth.
• Filter replacement: Replace the filter regularly according to the filter life indicator. Filter performance may vary based on water quality. Replace if blocked prematurely.
• Cleaning: Clean the system with clear water only. Do not use steel wool, abrasive cleaners, or corrosive liquids.
• Water quality: If feed water has large particles or high hardness, install a pretreatment device.
• Sewage tubing: Ensure the sewage tubing is not blocked to prevent sewage backup.
• Leak checks: Regularly check water tubing fittings for leaks to prevent property damage.
• Power checks: Regularly check the power supply and cord for damage to prevent electrical hazards.
• Accessories: Use only company-provided installation accessories. The company is not responsible for issues caused by third-party accessories.

Troubleshooting

a. After the system is plugged in, it cannot be powered on.

Check the power under the sink, ensure the plug is securely connected to the outlet. Try another power outlet. If the issue persists, contact customer service.

b. No water comes out of the faucet or the faucet discharges water slowly.

• Check the filter lifespan indicator.
• Ensure water inlet pressure is between 14.5-87 psi.
• Turn on the water supply valve.
• Check for crimped tubing and remove any kinks.
• Confirm all water tubing joints are correctly connected and fastened.
• Ensure the service temperature is within the 41-100 °F range.
• If using well water, contact customer service for assistance.

c. High TDS of filtered water.

The system provides 90%+ TDS rejection after flushing. If TDS is high:

• If the system hasn't been used for a long time, run the faucet for a while to normalize TDS.
• Replace the filter if it has expired.
• Check and remove kinks or blockages in the waste water pipe or drain saddle.
• Source water may have a high TDS, reducing rejection rate. Contact customer service for solutions.

d. Filtered water from the RO faucet tastes like tap water.

• Ensure waste water tubing is not connected to the faucet.
• Replace the filter if it has expired.

e. Water is not hot when taking hot water.

• Confirm the system is in heating mode.
• Verify the heating temperature has been set correctly.
• Allow time for the system to heat; the water may initially be warm.
• The system can continuously produce hot water for approximately 50oz/1.5L before needing to reheat. Check the real-time outlet water temperature on the faucet screen.
• If the issue persists, the heating module may be damaged. Stop using the system and contact customer service.

f. Hear the heating sound of system every once in a while.

The system automatically heats when the tank temperature drops below 7.2°F / 4°C of the set temperature. You can disable the heating function if hot water is not needed.

g. The outlet water temperature is inconsistent with the temperature displayed on the screen.

This can be due to residual cold water in the tubing, the system displaying tank temperature in standby vs. flow temperature, or a temperature sensor error.

h. The maximum temperature of the system is set below 203°F/95°C.

The system intelligently adjusts the maximum heating temperature to be 9°F / 5°C below the local boiling point to prevent boiling and scalding.

i. Loud sound of RO system.

The sound should not exceed 65 dB. Loud sounds may be caused by:

• The system not being placed on a flat, stable surface.
• The system being placed against the cabinet, causing vibration.
• Unstable water pressure. Ensure pressure is between 14.5 psi and 87 psi.

j. The heating switch cannot be turned on.

• Ensure the system is not in the initial flushing state or during filter replacement.
• Check for error codes on the system and faucet displays. If an internal error is indicated, heating may be disabled. Consult the fault code for resolution or contact customer service.
