INSTALLATION

Prior to installation, it is highly recommended to watch the video “Slevoo- KFRO 1000U-F3 RO Water Filtration System Installation” on YouTube.

2.1 Step 1. Install The Feed Water Adapter

1. Close the cold water supply valve. Keep the kitchen faucet tumed on to release the water pressure. Remember to put a towel under the inlet valve to catch any water.

2. Disconnect the cold water pipe (connect with kitchen faucet) from the cold water supply valve.

3. If it is a 3/8″ outlet valve, connect the Feed Water Adapter to the cold water supply valve and tighten it up with wrench.

4. Connect the cold water pipe fo the feed water adapter with the original washer in between. Then tighten the pipe firmly with an adjust-able wrench (Figure 4).
   Note: For 3 and 4, If the cold water pipe is 1/2″instead of 3/8″, please use the attached 1/2″ converter (Figure 5).

5. Insert the white 3/8″ PE pipe to the adapter. Please make sure the pipe is fully inserted.

2.2 Step 2. Install The Faucet

1. Push the 1/4″ PE pipe into the Quick-Connect Fitting inside the faucet and make sure it is fully inserted.
2. Put the faucet mounting-washer through the PE pipe and faucet power cord, and then pass the PE pipe and faucet power cord through the faucet mounting hole.
3. Insert the faucet into the hole on the countertop.
4. Under the sink, screw the lock washer wing nut into the faucet threads until the faucet fits securely (Figure 6).
   Note: Please confirm if there is an existing hole available to install the faucet, if not, please drill a hole in accordance with the following steps.

How to Drill a Hole into Your Sink or Countertop
It’s highly recommended to was the YouTube video “How to Drill Faucet Holes” for a better understanding of the process. When driling the hole, please remember to wear safety goggles to protect your eyes.

1. Choose matching dirill bits for the material of the counter: use diamond core for granite, and use a carbide drill bit for stainl steel. Avoiding using a hammer drill on natural stone, glass or cerami
2. Make an indent with a center punch on a stainless-steel sink before drilling to help guide the bit.
3. Need to drill a suitable hole according to the size (0.98™1.26″/25-32mm) of the faucet pr stallation hole. Start driling at the lowest speed with a 1″ drill bit, and hold the drrill straight with firm pressure to prevent the kit from slippin:
4. Once the drill bit breaks through the surface, slightly swirl the drill to apply pressure in a circle evenly.

2.3 Step 3. Install The Waste Water Pipe

1. Choose a preferred location on the drainpipe to install the drain saddle. We highly suggest to install the drain saddle on the vertical directed drainpipe.
2. Drilla 1/4″ hole on the side of the drainpipe. Be careful not to penetrate the other side of the drainpipe.
3. Place the front plate on the end of the remaining 1/4″ PE pipe, and align the two holes (Figure 7).
4. Place the back plate on the other side of the drain pipe to combine fo the front plate. Use the adjustable wrench to tighten the plates with screws and nuts evenly.
5. Insert the lock clip into the fitting to secure the connection (Figure 8).
   Note: Please make sure that the drain pipe is not bent, otherwise it may affect the filtering effect and result in high TDS of the filtered water.

2.4 Step 4. Position the RO System Housing
Note: It is not recommended to place the housing against the cabinet, as there may be vibrations when the system works.

1. The power-supply receptacle for the appliance shall be installed in a cabinet or on a wall adjacent to the undercount-er space in which the appliance is to be installed.
2. There should be an opening through the partition between the compartments specified in (1) that is large enough for the attachment plug to pass through.
3. Care should be exercised when the appliance is installed or removed in order to reduce the likelihood of damage to the supply cord.

2.5 Step 5. Connect Pipe
If the pipe is too long, cut it to a suitable length with a sharp utility knife. Cut the pipe squarely and cleanly, burr-free, and the pipe should not have obvious deformation due to extru-sion (Figure 9).

1. C2 B2 A2
   Remove the plug from the “INPUT”, “FILTERED”, “WASTE” water port.

2. Install the “INPUT” Water Pipe
   Identify the white 3/8″ PE pipe which has been attached to the feed water adapter; Insert the other end of the pipe into the “INPUT” water port [Figure 10], make sure it is fully inserted. Then insert the lock clip into the fitting (Figure 11].
   Note: Please try to ensure that the PE pipe is connected as straight as possible, and do not bend excessively otherwise it will easily cause water seepage at the connection.

3. Install the “FILTERED” Water Pipe
   Identify the white 1/4″ PE pipe that has been connected with the Quick-Connect Fitting inside the faucet. Insert the other end of the pipe info the “FILTERED” water port, make sure it is fully inserted (Figure 12). Then insert the lock clip into the fitting (Figure 13).

4. Install the “WASTE” Water Pipe
   Identify the 1/4″ PE pipe which has been attached to the drain saddle. Insert the other end of the pipe into the “WASTE” water port (Figure 14), make sure it is fully inserted. Then insert the lock clip into the fitting (Figure 15}.

5. Connect the faucet power cord to the system
   Insert the power cord which is attached to the faucet into the “FAUCET” connector at the back of the housing (Figure 16).

2.4 Step 6. Plug In The Power and Start Up System

1. Turn on the cold water supply valve. Check for leaks.
   Note: If there is water leakage at the connection position, please tighten the joint or make sure the PE pipe is fully inserted.

2. Connect the power adapter to the power port on the machine then plug the power adapter into the power outlet (Figure 17).

3. Turn on the faucet. The machine will automatically start flushing for 30 seconds. Then let the faucet runs for 30 minutes to flush out the RO filter.
   Note: Some black water may flow out of the faucet because activated carbon powder in the filter for the first time. The purpose of continuing to turn on the faucet for 30 minutes is to drain the small particles of activated carbon powder.
   Be sure to carefully check the tightness of each part of the system while flushing. Check and ensure all pipe is installed correctly and completely. Make sure there are no leaks at the joints, fittings, valves and pipe connections.
   Be aware that a slow water flow is normal when the faucet is turned on, and the water is NOT drinkable during the flushing process.

4. Confirm the flush is completed before tuming off the faucet and ensure it’s not leaking.

How 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 pipe from the fitting (Figure 18).
Note: Plecse close the water valve and open the faucet to relieve pressure before disconnectting the PE pipe.
Please do not pull out the pipe directly. This wil damage the fitting and cause leakage.

DISPLAY AND OPERATION

3.1 POWER INDICATOR

3.2 FILTER LIFE REMINDER

1. Faucet
   The color of faucet light remind you the state of fitter.

2. Filter Life Indicator on System Housing
   There are helpful electronic filter indicators (PP+CF/GAC/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.

3.3 DISPLAY STATUS

Note: The indicators will notify you according to the usage time or processing capacity of the filters, whichever comes first.
3.4 FILTER REPLACEMENT CYCLE Note:

1. Actual lifetime of the filters varies from different regions, water quadlity, season and usage. Please replace the filters according to the reminder from the filter lifetime indicator.
2. If the filters expire, please purchase and replace the filters as soon as possible. Otherwise, the filtration efficiency will be greatly reduced and affect performance.

3.5 FILTER REPLACEMENT STEPS

1. The filters could be replaced directly without cutting off the power and water supplies, and there will be no water and electric leakage.
   Note: Before removing the filter, turn off the valve first and turn on the faucet to fully release the internal pressure of the RO machine, which makes the fiter easier to remove and install.

2. Twist off the filter that needs to be replaced in a counterclockwise direction, then pull out the expired filter.

3. Insert new filter info the corresponding hole, then follow the direction of the arrow to twist the filter.

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 (Taking Reset of RO Mem- brane Filter as an Example):
   Press the RO Memlbrane Filter Reset for 3 seconds until the system beeps.
   Note: Refer to the above method, Polypropylene Carbon Fiber Compoisite Filter [PP+CF) Reset and Granular Activated Carbon Filter (GAC) Reset to reset the coresponding filter.

5. Restart the system. Turn on the faucet to flush out the filters. Do not drink until the 30 minutes of flushing process is completed.

3.6 CONNECT REVERSE OSMOSIS TO REFRIGERATOR/ICE MAKER
Reverse osmosis to refrigerator/ice maker connection is possible depending on the refrigerator type and RO system model.
However, we want to draw your attention to a few things you should keep in mind.
4 Things to Keep in Mind before Making the Connection

1. Check for Compatibility
   Some refrigerator companies will let you know if their products are not compatible with RO systems due to a difference in pressure. This is because for the water valve to operate as it should, the fridge has to be pressurized at a higher PSI (pounds per inch) than what RO systems are able to deliver on their own.

2. Purge the RO System
   Before connecting an RO system to your fridge, you’d need to first purge the system. Purging the reverse osmosis system before connecting to a fridge is essential to prevent excess carben from the system from clogging the fridge, especially if the fridge has a built-in water fiter.

3. Pay Attention to the Water Line Distance (and the Pressure)
   The way reverse osmosis works when connected to a fridge is; the water line is fed to the RO system, and then the filtered water line goes through a pipe and into the refrigerator.
   Running a long water line might end up disrupting the water pressure. So, it’s important to keep the water line between the water source (tap), RO system and refrigerator as snort as possible.

4. If your fridge has a copper pipe leading to the ice maker or water dispenser, you won’t be able to connect the RO filter. It’s dangerous to use reverse osmosis-treated water in copper pipes due to the water being more susceptible to metal leaching.

How to Connect a Reverse Osmosis System to Refrigerator
The refrigerator kit is only suitable for most refrigerators or ice makers with 1/4″ quick connectors. Please consult customer service for other specifications

1. The first thing that you should do is shut off the cold water line that is feeding your RO system.
2. Next, locate the pipe that should extend from the RO system to the faucet. Remember to place a container under that pipe in order to keep the surface beneath it dry.
3. Cut the pipe to required measurements. This all depends on where the pipe comes out of your RO system, how long the pipe is, and the space you have. The system will be able to drain the water straight into the container below through the pipe.
4. Once you’ve turn on the faucet and drained the water, install a tee fitting on one end of the cut pipe, and connect the other end that goes to your faucet to the same fitting.
5. After that, take a new pipe and slot it info the tee fitting that runs perpendicular to the line to your faucet. The other end of this pipe should run to the shut-off valve. The valve will regulate the water and the pressure coming from the filfration system and into your fridge.
6. The valve should be turned off at all times and perpendicular to the pipe line. You can let the valve run only after the instal- lation has been completed.
7. The next step is running a pipe from the other end of the valve into your fridge. Be mindful of the water pressure here—it has to match the levels that your fridge is capable of taking. Check the instruction manual of your fridge or reach out to the manufacturer for more information.
   Once you’ve installed all the pipes properly, your RO-to-fridge connection should be working.

As an additional note, when changing your RO filters after this procedure, first shut off the inline valve, then flush the system.
If you find the following problems, you can order a Mini Water Tank For Reverse Osmosis Systems to solve them:
a) occasional pulsing of the system caused by unsta-ble water pressure, especially when it is connected to a refrigerator or long distance point of use.
b) initial time lag of water output of tankless reverse osmosis system.

MAINTENANCE

1. If you don’t use the system for a long time, shut off the cold water valve, turn on the faucet to empty the water, and disconnect the power. Seal the filters and store them in the refrigerator (not the freezer). You need to open the faucst and allow it o run for 10 minutes first before using the system again as bacteria may grow when the system is not used for along time.
   Please replace the fiter regularly according to the filter life indicator.
   Note: 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 premature blockage and failure of the filters, it’s recommended to replace the filter in accordance with the actual usage.

2. Clean the system with clear water. Do not spray the water directly. Do not use steel wool, an abrasive cleaner or como- sive liquid such as gasoline or acetone.

3. When cleaning, do not pour other liquids into the filter to avoid damage to the filter system.

4. Keep the waste water pipe unobstructed to avoid damage to the filter or internal components.

5. When the drain pipe is blocked, do not use the system (please turn off the power) to avoid waste water from soaking the floor.

6. Check the system and water pipe fittings regularly for water leakage to avoid any property damage.

7. Regularly check whether the power supply and wires are damaged or loose to avoid major accidents caused by electric leakage.

8. 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.

9. When the inlet water temperature is lower than 41°F/5°C, turn off the cold water supply valve, turn on the faucet and let the water flow for about 1 minute to prevent freezing and damage to the machine.
   Note: The noise of the machine may be higher during this period.
   Be sure to cut off the power after the water purifier is drained.

10. Automatic Flushing
    The system automatically enters flushing mode under the circumstances below:

a) For The First Time Using
When the power is on, the system will automatically switch to auto-flushing mode and start back-flushing for 30 seconds.
b) For Accumulative Working Time Over 24 Hours
To maintain and extend the lifetime of the filters, the system will do auto back-flushing for 30 seconds when it accumulatively works up to 24 hours. If you decide to take water during the flushing, the system will quit flushing and switch to dispensing.
Note: To save water resources and maintain and extend the service life of the water filter, the system will automatically shut down after working for 1 hour (the faucet is continuously opened for one hour). The fault can be resolved by power-ing on and powering off the system using the power cords.

FAQ

Q: Why the system can't be powered on after inserting the plug of power adapter?

A1: Power failure: Check if there is power outage. Check the power under the sink, as this mostly occurs when the power under the sink is off. Check if the power adapter is properly connected to the machine and power outlet. Or simply disconnect the system and try another power outlet. A2: Power adapfer failure: Check if the adapter light is off. Replace the power adapter. If you are unsure about the model of adapter, please contact our Customer Service for further assistance.

Q: Why there is no water dispensing from the faucet or the water output becomes weaker?

A1: Excessive bending of water pipe: Check and straighten out the pipe. A2: RO feed water adapter is being turned off: Check and make sure the feed water adapter switch is being turned on totally. A3: Water outage occurred: Check if there are any water outage in the area. If yes, please wait for the local water supply to be fixed. A4: Filters clogged: Check filters to see if they are properly inserted. Make sure dll the filters are replaced and have not expired yet. AS: Leak from pipe connection: Check and make sure the pipe is properly connected and no leakage on the pipe(s). Aé: Temperature of feed water is low: Check and make sure the system runs at water temperature between 41°F-100°F.

‘Q: Why TDS in filtered water is so high?

The system will provide a 95%+ TDS rejection rate (tested under standard laboratory conditions) after full flushing when work- ing properly, if the TDS reading is high, the following are possible causes: A1: The system hasn't been used for a long time. Open the faucet, allow it to run for a while. The TDS reading will return to normal A2: The RO filter expired. Replace the RO filter immediately. A3: The waste water pipe may be crimped or clogged. Check and remove crimps. Re-align the drain saddle and drain pipe. A4: 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 replocement.

Q: Why the pure water looks dirty?

A1: Activated carbon particles: It is normal that the pure water tuns black with activated carbon particles in the new filter. Do not drink until the 30 minutes of flushing process is completed.

Q: Why the pure water smells abnormal?

A1: Tumn on the faucet for 30 minutes to flush out the filters. A2: Expired filters remain unchanged for a long period: Replace the filters. A3: The machine has remained unused for a long period: Restart the machine and turn on the faucet to run for 10 minutes. If the smell remains, please replace the filters.

Q: Why the filtered water from the faucet tastes like tap water?

Al: Incorrect pipe installation. Make sure the waste water pipe is not connected with faucet. A2: The filters are not well-installed. Make sure the filters are placed properly. AZ3: Filter expires. Check the filter life indicators to confirm which filter needs to be replaced and replace immediately.

‘Q: Why the filters are clogged shortly after filter replacement?

A1: Actual lifetime and condition of a filter may vary due to different quality of water supply or different water usage. Poor water quality and high operating frequency might lead to the shorter lifetime. It is recommended to add a pre-filtration system.

‘Q: Why the machine makes loud noise during operation?

It is normal for the water purifier to have slight vibration and sound when purifying water. The sound will not exceed 60 dB, which makes no difference to everyday lives (60 dB is tested under standard laboratory conditions, where the feed water pressure is between 14.5 psi and 58 psi. A loud sound may be caused by the following reasons: A1: The system is not positioned in a flat area. Make sure the system is placed smoothly without shaking. A2: The vibration generated by the pump: Move the machine away from the side wall. Do not place the machine against the side wall or on the uneven ground. A3: Unstable feed water pressure: Check and confirm the water pressure is between 0.1-0.4MPa. A4: Abnormal power voltage: Contact our support team for assistance. Do not attempt to repair as there may be electrical leckage.
