Safety instructions

This device is intended to operate and function according to the instructions in this manual. It is not designed to work outside the listed specifications, and any attempt to do so or tamper with the device may result in damage to the device and/or personal injury.
This device is not a toy; keep it out of reach of small children. If the device needs maintenance or repair, please contact your local service technician.
Ensure the feed water temperature is above 4 ℃. Water temperatures below 4 ℃ can cause ice formation and damage the device.
Before connecting the device, make sure the power source is correct. Incorrect voltage can cause damage to the device and/or a fire hazard.
Do not damage the device or use it if the power cord is damaged. A damaged power cord can cause electric shock or fire. If the power cord is damaged, unplug it immediately and do not use the device.
Read all instructions before starting the installation and operation of the system. Follow all steps precisely to avoid damage to the system or improper operation.
This system contains filters that need to be replaced at certain intervals. The replacement intervals vary depending on usage; please contact your local dealer.
Install the system with potable water only, as the system will not function properly with non-potable water sources and may require additional pre-treatment.
Ensure that the source water pressure is within the recommended range. If the source water pressure exceeds the maximum pressure of 7 bar, a pressure-reducing valve may be required.
Ensure that the source water temperature is between 5 ℃ and 45 ℃. The system will not func-tion properly if these temperatures are exceeded.
Do not install the system on a hot water source.
Do not use the system for noticeably contaminated water such as raw sewage or well water.
This device must not be disassembled, opened, or altered. Tampering with the device can lead to malfunction or damage and will void the warranty.
Do not cover the device, as this will prevent proper heat dissipation and can lead to damage or fire.
Do not place any objects on the device, as this can cause damage and leaks.
Adhere to all recommended operating pressures and temperatures; otherwise, the device will be damaged. Avoid contact with corrosive materials.
Keep away from heat sources.

No-power water flow

Placement of units

This device is designed to be installed under the sink or on the countertop. However, if due to space constraints or other limitations, you need to place this device in a suitable location, please ensure that it is accessible and convenient.
When choosing the installation location, make sure that the cold water line, drain pipe, and power outlet are easily accessible and that there is enough space for filter replacement.

Pressure tank

Keep the pressure tank within a 3-meter radius of the faucet.
If longer hoses are needed, use only ¼″ hoses to avoid pressure drop.
The tank can weigh up to 13.5 kg (30 lbs) when full; place it on a firm and level surface.
Install the ball valve by screwing it onto the tank and sealing it with Teflon tape to prevent leaks.
Connect the yellow hose from the post-filter to the pressure tank.
Apply Teflon tape to the fitting on top of the tank.
Install the tank valve and tighten it hand-tight.
Connect the yellow hoses from the system.
Ensure the valve is open.

Tank ball valve

Feed water valve and T-piece

Install the T-piece and feed water valve as shown in the diagram.
Wrap the threads of the feed water valve and T-piece with Teflon tape.
Connect the white feed water hose from the device to the feed water valve.

Installing the feed water valve

Install the T-piece of the feed water valve and connect it to the water source.
Caution! The water supply to your device must come from the cold water line!
Note! Use only cold, local water as feed water. Hot water will damage your device. Softened feed water extends the lifespan of the reverse osmosis membrane

Installing the wastewater clamp

Place the wastewater clamp on the drain pipe above the siphon and tighten it securely.
Using the wastewater clamp as a guide, drill a 6 mm hole that is large enough to pass the ¼″ tubing through one side of the drain pipe. Do not drill through both sides.
Connect the red wastewater hose from the device to the wastewater clamp.

Wastewater clamp assembly

Installing the faucet

Select a suitable location near your sink for the faucet.
Drill a 12-mm diameter hole in the countertop.
Attach washers, plates, gaskets, and nuts in the order shown in the diagram, and tighten them securely on the countertop.
Attach the blue purified water hose to the bottom of the faucet and connect the hose to the device.

Operation and maintenance

LED display and control panel

When powered on, the light illuminates brightly, the buzzer sounds once, the screen flashes once, and the system starts operating. During the automatic flush, which lasts 60 s, the washing symbol (Washing) blinks.
The device is in water production mode when the water production symbol (Source) is displayed. Once the pressure tank is full, the water production symbol turns off, and the full tank symbol (Full) lights up.
In case of water shortage or insufficient water pressure, the water shortage symbol (Lack) lights up and the buzzer sounds 10 times.
The machine produces water for a total of 2 hours. During this period, no flushing occurs. After 2 hours, the machine automatically flushes for 30 s.
The machine stops automatically after 6 hours of water production or if a water leak is detected. Alarm message: The check symbol blinks, and a buzzer sounds.

Filter replacement reminder

1st and 2nd filters: after 270 hours – 3rd filter: after 1620 hours – 4th filter: after 540 hours
Increased water consumption or exhausted filters trigger an alarm, and the corresponding sym-bol blinks.
After replacing the filter, press the reset button to reset the filter recognition

Resetting the filters

Press the reset button for less than 3 s to activate the filter selection.
Press the reset button again to select the filter you want to reset.
The symbol for the selected filter blinks.
Hold the reset button for over 3 s to reset the selected filter.
After 3 s, a beep confirms the successful reset.

Flush button

Pressing the flush button: the buzzer sounds once.
Pressing the flush button during flushing stops the flush program.
Pressing the flush button during water production or when the water tank is full, flushes the reverse osmosis membrane for 120 s.

Prefilter flushing (initial setup)

Disconnect the inlet pipe of the reverse osmosis element.
Open the main water valve and the inlet valve, allowing water to run through the prefilters.
Dispose of the water that exits during flushing.
Continue flushing until the water is clear.
Reconnect the inlet pipe.

Caution! The pump and membrane can be damaged if the prefilters are not flushed.

Pressure tank flushing

Allow the device to operate and fill the pressure tank.
The tank takes about 3.5 hours to fill.
Empty the tank by leaving the faucet open.
Once the tank is empty, close the faucet and allow the tank to refill.

Regular operation

The device automatically starts water treatment when the faucet is opened.
It shuts off automatically when the faucet is closed.
After use, the device automatically flushes if equipped with an automatic flush function

Filter maintenance
Regular maintenance is required to ensure optimal performance. The frequency of maintenance depends on the quality of the feed water

PP filter and block carbon filter: every 3–6 months
Inline carbon filter: every 6–12 months
Reverse osmosis membrane: every 18–24 months

For extended periods of non-use, disconnect the device from the power supply. If the device has not been used for a long time, follow the same flushing procedure as during the initial setup.Filter replacement

Filter replacement

Close the feed water valve.
Close the ball valve on the pressure tank.
Open the faucet and drain the remaining water.
Turn the old cartridge clockwise to remove it.
Align the new cartridge and gently insert it into the hole.
Turn it counterclockwise to secure the new cartridge.
Flush the prefilters after replacement
