Installation Tips

How to Use the Quick-Connect Fittings

To connect:

There is an existing mark (Figure 1) at the end of the tubing for you to confirm if the tubing is fully inserted into the fitting. Please push the tubing into the fitting until it reaches the mark on the tubing (about 0.8″). Put the blue lock clip on the fitting. It will lock the tubing in place and prevent it from falling off.

NOTE:

• If the tubing is not fully inserted, no seal will be created, and leakage will occur.
• 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. (Figure 2).

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 (Figure 3).

NOTE: Please do not pull out the tubing directly. This will damage the fitting and cause leakage.

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

NOTE: Please confirm if there is an existing hole available to install the RO faucet. If not, please drill a hole in accordance with the following steps. It’s highly recommended to watch the YouTube video “How to Drill Faucet Holes” for a better understanding of the process. There is also a reference sticker to help you drill the hole. Remember to wear safety glasses to protect your eyes while drilling the faucet hole.

• a. Choose a suitable place to install the faucet and leave enough space for the nut to avoid touching the wall or sink.
• b. 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.
• c. Glue the sticker on your sink or countertop, and then drill a hole the size of the sticker hole (7″).
• d. Make an indent with a center punch on a stainless-steel sink before drilling to help guide the bit.
• e. 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.
• f. Starting at the lowest speed, hold the drill straight with firm pressure to prevent the bit from walking on the counter.
• g. Once you break through the surface, swirl the drill a little to apply pressure in a circle evenly.

Installation Steps

• Before installation, remove the system from the box and choose an easy-to-access area under the sink to place it. An adequate flat area is necessary to allow the system to rest securely. Do not lay it on its side, on its back, or upside down.
• Also, before installation, ensure that there is a power outlet in the cabinet or on the wall connected to the lower cabinet space. & WARNING: The system plug must be inserted into a grounding socket that complies with local codes and regulations. Additionally, ensure that the system does not share the same power outlet as the garbage disposal.
• The system must be connected to the COLD water supply ONLY.
• Do not install the system where it will be exposed to direct sunlight or harmful chemicals, nor in 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″)

• a. Shut off the water supply. Turn on the kitchen faucet to release the water pressure. NOTE: Make sure the water has stopped flowing before moving on to the next step. Get a towel or bucket to catch any excess water.
• b. Disconnect the cold water pipe from the cold water supply valve.
• c. Twist the feed water adapter onto the cold water supply valve (with its washer) and tighten it with an adjustable wrench (Figure 5). The “INLET” water tubing has been attached to the feed water adapter for easy installation. NOTE: If the cold water pipe is 1/2″, unscrew the two converters from the feed water adapter (Figure 6), and then implement step c.
• d. 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

NOTE: If your kitchen sink or countertop does not have an existing hole, you will have to drill one (7″). (Refer to Page 4)

• a. Insert the faucet stem, the power cord, and the filtered water tubing into the decoration base and the hole on the countertop in turn.
• b. Under the sink, slip on the nut and tighten it up (Figure 7). NOTE: The maximum rotation angle of the faucet is 720°, and please use the faucet within this angle range. To avoid damage, do not pull the faucet hard.

Step 3: Install the Drain Saddle

• a. Stick the foam seal on the front plate of the drain saddle. Ensure that the hole of the foam seal is aligned with the hole of the front plate.
• b. Choose a spot on the drainpipe that is convenient for installing the drain saddle (Figure 8). Drill a 7/4″ hole in the drainpipe. Be sure not to penetrate the opposite side of the pipe. NOTE: It’s recommended to install the drain saddle on the vertical drainpipe.
• c. Slip the front plate over one end of the tubing (without a mark) and insert the tubing into the drilled hole for about 0.6″ (Figure 9).
• d. Position the back plate on the drainpipe by tightening the screws and nuts evenly while leaving the tubing in the hole. & WARNING: To ensure smooth drainage and exhaust of the system, the drain water tubing must not touch the side wall of the drainpipe. During heating, do not pull out the waste water tubing from the sewer to avoid scalding.
• e. Pop the lock clip onto the fitting to secure the connection (Figure 10).

NOTE: In some areas, the drain tubing must be connected to the drainpipe through the air gap. Consumers must purchase air gap accessories separately.

Step 4: Position the System Housing

Ensure that there is sufficient space under the countertop to install the system (6.7″ \7.5″ \6.6″) (Figure 11). Set aside 2 inches of space around the system to avoid placing the system against the cabinet.

• a. The power-supply receptacle for the appliance shall be installed in the cabinet or on the wall adjacent to the undercounter space in which the appliance is to be installed.
• b. There should be an opening through the partition between the compartments specified in (a) that is large enough for the attachment plug to pass through. The longest dimension of the opening shall not be more than 7.5″ (38 mm).
• c. If the partition is made of wood, the edges of the opening specified in (b) should be smooth and rounded. If the partition is made of metal, it should be protected with an edge protector provided by the manufacturer.
• d. Caution should be exercised when installing or removing the appliance to reduce the possibility of damage to the supply cord.

NOTE: Position the front panel facing you, which will be convenient for future filter replacement and indicator checking. You can also adjust the placement direction of the system according to the layout under the sink.
The system must be installed horizontally, not tilted, placed on the side, lying on the side, or inverted.

Step 5: Connect Tubing

NOTE: 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 3. Before connecting the PE tubing to the system, remove the plugs from the corresponding water ports (Figure 12).

Connect Tubing Step (Figure 13)

• a. Insert “INLET” water tubing (white tubing) into the “INLET” port (white water port)
• b. Insert “PURE” water tubing (blue tubing) into “PURE” port (blue water port)
• c. Insert “HOT” water tubing (red tubing) into “HOT” port (red water port)
• d. Insert “DRAIN” water tubing (gray tubing) into “DRAIN” port (gray water port)

NOTE: Make sure it is fully inserted until you reach the mark on the tubing and pop up the lock clip (Figure 14).

Step 6: Connect the Faucet Power Cord

Insert the faucet power cord, which is connected to the faucet, into the “FAUCET” connector at the back of the housing and tighten the nut (Figure 15). NOTE: When connecting, please pay attention to aligning the notches and protrusions on the connector. NOTE: DO NOT insert the plug into the socket yet.

Step 7: Start up the System. 

• a. Turn on the cold water valve. Check for leaks.
• b. Insert the system’s power plug into the socket. & WARNING:
• The system plug must be inserted into a grounding socket that complies with local codes and regulations.
• If the system can’t be powered on after you insert the power plug, check whether the power plug is live; if the power plug is live and the system still cannot be powered on normally, please feel free to contact us.
• c. Flush for 60 seconds for first-time use.
  After being powered up, the system starts flushing automatically for 60 seconds. The screens on the system and the faucet display a 60-second  countdown.
• d. Turn on the faucet and flush for 15 minutes. Touch the key and turn on the faucet. The system starts flushing for 15 minutes until there is no water output from the faucet. During the flushing period, the system will inject water into the heating tank. There will be no water coming out of the smart faucet at this time, and no action is needed until the flushing is completed and the system automatically goes into standby mode (Figure 16).

Step 8: Check Leakage

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. Congratulations! You have successfully installed the system. Please follow the instructions to set up the heating function.

Troubleshooting

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

• Please check whether the power under the sink is off
• Please check whether the power plug is correctly plugged into the power outlet.
• To test whether there is a problem with the system itself, simply pick up the system and try another power outlet.
• Please contact us if the system cannot be powered on. We will help you figure it out.

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

• Please check whether the filter has expired and needs to be replaced.
• Please check whether the water inlet pressure is too low, and make sure the water inlet pressure is between 74.5-87 psi.
•  Please check whether the water supply is off. If yes, turn on the feed water adapter or the water supply valve.
• Please check whether the tubing is crimped and remove any crimps.
• Please check whether there is water leakage at water tubing joints and confirm that all pipes are connected correctly and fastened.
• Please check whether the service temperature is too low, and make sure the temperature of water used by the system is in the range of 5–38°C.
• Please check whether well water is used as the water source. In this case, please make sure to contact us, and we will give you a better solution.

c.High TDS of 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. Turn on the RO faucet to allow it to run for a while. The TDS reading will return to normal.
• The filter expired. Replace the filter immediately.
• The wastewater 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, thereby making the TDS removal rate lower than 90%. In this case, please make sure to contact us, and we will provide a satisfactory solution.

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

• Incorrect tubing installation. Make sure the wastewater tubing is not connected to the faucet.
• Filter expires. Please check the filter life indicator, and if the filter has expired, please replace the filter right now.

e.Water is not hot when taking hot water.

• Please confirm whether the system is in heating mode.
• Confirm whether the heating temperature has been set; the system will heat to the specified temperature according to the setting. The temperature setup range is 40–95°F.
• The system takes time to heat. Immediately after the heating temperature is set, the system will not be at the set temperature. Before that, the water in the heating tank may be warm.• The system can continuously produce hot water in amounts of about 50 oz / 1.5L at a time. Then the water will slowly cool and need to be heated to the set temperature again. In the process of obtaining hot water, you can check the outlet water temperature in real time through the faucet screen.
• If the above reasons are not confirmed, the heating module may be damaged. In this case, please stop using the system and contact us.

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

• When the system detects that the temperature of the heating tank is lower than 4°C / 7.2°F of the set temperature, it will automatically heat to the set temperature. If you will not need hot water for a while, you can disable the heating indicator on the system.

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

• Because there is some cold water in the system’s water tubing, there will be some cold water initially.
• There may be a deviation between the displayed temperature and actually measured temperature. This is because the temperature of your cup is low, and heat loss occurs when hot water is poured into your cup. If you want to measure the actual water temperature, please put a thermometer at the faucet outlet for accurate temperature measurement.
• The temperature sensor has an error, resulting in temperature display deviation.

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

• The system can intelligently determine the local boiling point temperature. If the system determines that the local boiling point temperature is lower than 95°C / 203°F, the system will automatically reduce the maximum heating temperature to 5°C / 9°F lower than the boiling point to avoid boiling, scalding, and other risks.

I. 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 74.5 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 74.5 psi and 87 psi. The sound will decrease when the water pressure becomes stable.

j.The heating switch cannot be turned on.

• Confirm whether the system is in flushing status for the first time or replacing the filter. When flushing for the first time or replacing the filter, the heating switch cannot be enabled.
• Check whether there is an error code on the system and the faucet display. In case of internal errors of the system, the heating function cannot be turned on. Please check the cause according to the fault code. If it cannot be solved, please contact us right away.
