• The environment where the system is installed should adhere to appropriate hygiene and sanitation conditions. Avoid any external dripping liquids from pipes or drains, etc, onto the system.
• This system should be placed on a stable and at the surface.
• Keep the system away from heat. It shall not be placed in a place that may have in-inflammable gas leakage.

How to use the quick-connector fitting

To connect

• There is an existing mark at the end of the PE tubing for you to confirm if the PE tubing is fully inserted into the fitting.
• Push the PE tubing into the fitting until you reach the mark on the tubing.

NOTICE
If the PE tubing is not fully inserted, no seal will be created, and leakage will occur.

• When the PE tubing is fully inserted, put the clip on the fitting. It will lock the PE tubing in place and prevent it from falling off.

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

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 PE tubing from the fitting.

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

Selecting the Faucet Location
Most sinks have pre-drilled holes designed for spray hoses. The RO faucet may be through using one of these holes despite their larger size. If these pre-drilled holes cannot be used or are in an inconvenient location, it will be necessary to drill a 1″ hole in the sink or through the countertop next to the sink.

CAUTION

• This procedure may generate dust, which can cause severe irritation if inhaled or come in contact with the eyes. Safety glasses and a safety mask are recommended for this procedure.
• Do not attempt to drill through an all-porcelain or porcelain-coated sink. For applications on these types of sinks, we recommend using the sprayer hole or drilling the hole through the countertop.
• When drilling through a countertop, make sure the area below the drilled area is free of wiring and piping. Make certain that you have ample room to make the proper connections to the bottom of the countertop.
• Do not drill through a countertop that is more than 1 inch thick.
• Do not attempt to drill through a tiled, marble, granite or similar countertop. Consult a plumber or the countertop manufacturer for advice or assistance.

The following instructions apply to stainless steel sinks ONLY.

• (A)Line the bottom of the sink with newspaper to prevent shavings, parts or tools from falling down the drain.
• (B) Place masking tape over the area to be drilled to help prevent scratches if drill bit slips.
• (C) Mark the point with a center punch. Use a 1/4-inch drill bit to drill a pilot hole through the sink.
• (D) Use a 1″ hole saw to enlarge the hole. Smooth rough edges with a file.

Install the Angle Stop Valve for the feed water (3/8″ or 1/2″)

• (A) Turn off the cold water supply valve. Turn on the kitchen cold water faucet to release the pressure and allow water to drain from the line. Disconnect the cold water hose from the cold water valve.
• (B) Insert the 3/8″ white PE tubing into the angle (B) Insert the 3/8″ white PE tubing into the angle 
• (C) Install the Angle Stop Valve on the cold water valve and tighten it with an adjustable wrench. Please don’t miss the gasket inside the angle stop adapter during installation.

NOTICE
If the cold water tubing is 1/2″, screw the conversion adaptor upper the Angle Stop Valve.

• (D) Switch off the angle stop adapter. Turn on the cold water supply valve. Wipe the connections with a tissue to check for leakage. If the tissue stays dry, the angle stop valve is installed correctly.

NOTICE
If your kitchen sink or countertop does not have an existing hole, you will have to drill one (1″). Refer to chapter 3.2.

1. Insert the faucet spout into the faucet body.
2. Insert the faucet stem, power cord, and PE tubing into the hole on the countertop.
3. Under the sink, slip on the nut and tighten it up (Do not forget the washer).
4. Insert the quick-connector fitting into the PE tubing. Use a clip to secure the tubing.

Install RO drain connector

1. Identify drain outlet location.
2. Knock out the center hole on the foam seal (④).
3. Use the hole in the foam seal (④) as a template to locate your drilling position above the drain tap. Mark the location with a pencil. Note: If you have a double sink and cross- or horizontal drain tubing, it is safe to mark the drill location on the top of the horizontal drain tubing.
4. At the marked location, drill a 1/4″ hole through the wall of the drain tubing, being sure not to penetrate the opposite side of the tubing.
5. Remove the protective cover from the back of the foam seal (④) and attach it to the front plate of the drain connector (①) in alignment with the holes.
6. Begin to position the drain connector (①) on the sink drain tubing with Screws (②) and Nuts (③), using your pencil (or a thin pen) in the drain connector (①) tube hole to guide your location over your drilled hole as you securely tighten Nuts (③) and Screws (②).

Maintenance

If you plan on not using the system for one week or longer, take out the filter and seal it with plastic wrap. Store the sealed filter in the fridge to protect the system against microbiological growth. To start the system again after the period of non-use, flush the system for at least 10 minutes OR change the filters.
If you will not use the system for two weeks or longer, disconnect the water supply, drain the system, and disconnect the power.
Follow the recommended filter replacement schedule. Replace the filter any time the indicator is on. Note that the actual filter life depends on the family size and water source quality. Failure to replace the filter at the appropriate times can damage the system and potentially cause health hazards.

Filter Cartridge Replacement

NOTICE
The life of the filter cartridges depends on the water volume used and the quality of the feed water. For the best performance, please change your filter cartridge according to the filter lifetime indicator or the filter replacement cycle suggested below. When there is a noticeable change in taste, odor, or flow of filtered water, we recommend changing the filters as well.

Filter Service Life Table

The actual lifetime of the filter cartridge depends on the local tap water quality and daily usage. The recommended replacement cycle is an average based on different local tap water quality. If the local tap water quality is below the average, the actual lifetime of the cartridge would differ from the recommended replacement cycle. If the filter cartridge is blocked, please replace it.

Filter cartridge replacement

• Turn off the power and water supply before replacing the filter cartridges
• Remove the front cover.
• Turn the filter that needs to be replaced anticlockwise and pull it out (figure1).
• Remove the packaging of the new filter and insert the cartridge in the system. Turn it clockwise to align the triangle icon on the filter cartridge with the lock icon on the system (figure2).
• Turn on the water supply and re-connect with power. If the RO filter is replaced, turn on the faucet and allow the water to run for 30 minutes. If the PCF filter is replaced, turn on the faucet and allow the water to run for 10 minutes
• Reset the filter lifetime according to chapter 5.1.

Automatic Flushing
The reverse osmosis membrane features a filtration capacity as fine as 0.0001 microns, effectively removing contaminants. The flush mode helps expel accumulated contaminants from the membrane, ensuring a longer filter lifespan and delivering purer water. The system will automatically enter flush mode in the following situations:

1. Flush for Power Restore
   When power is restored after a blackout, the system will be forced to be flushed automatically for 30 seconds.
   While flushing, the flush indicator will flash a blue light.
2. Recycled Flushing
   The recycled flushing function ensures that each cup of water is fresh and healthy. The system will automatically recycle flushing after it has dispensed water for more than 10 minutes.
3. Flush for Accumulative Time per 24 hours
   To maintain and extend the life expectancy of the filters, the system will be automatically flushed for 300 seconds per 24 hours.
   The flush mode doesn’t affect the user when taking water. If the user decides to take water during the flushing, the system will quit flushing and switch to dispensing.
