Setup: Naturewater NW-3-1 100 Counter-top Ultrafilter System User Manual

Overview

The NW-3-1 100 Counter-top Ultrafilter System is a compact countertop drinking-water appliance for indoor use. It filters drinking water through a replaceable multi-stage cartridge and dispenses water at room temperature or selected hot-water settings.

This system is designed for kitchens, work areas, and other locations with a suitable electrical outlet. It is intended only for drinking water and combines filtration with controlled dispensing at 25 °C, 45 °C, 85 °C, or 100 °C.

Detailed Description

The appliance uses a feed-water tank, an internal pump, a purified-water tank, a heating element, and a replaceable filter cartridge. Water from the feed-water tank passes through the cartridge before entering the purified-water section. The system then delivers filtered water through the front outlet.

The cartridge combines three filtration functions. A PP sediment layer captures suspended particles and colloidal matter. Activated carbon helps reduce chlorine, unwanted taste, odor, color, and certain dissolved contaminants. The ultrafiltration membrane provides fine filtration for suspended matter, bacteria, viruses, and similar impurities within the cartridge’s stated filtration capability.

The main external components are the feed-water tank, control panel and display, water outlet, collection-container cover, collection container, main housing, and power cord. The collection container sits in front of the main housing and catches dispensed water or drips.

Safety

• Use the NW-3-1 100 Counter-top Ultrafilter System only with drinking water. Do not process chemicals or other liquids.
• Keep the appliance indoors and away from temperatures below 4 °C.
• Check that the water pressure is suitable before operation. Excessive pressure can damage the system, while insufficient pressure can reduce filtration performance.
• Keep every connection tight and correctly installed. Use an appropriate thread-sealing material where required.
• Inspect the appliance, tanks, cartridge connection, and surrounding area regularly for leaks. If a leak appears, stop the water supply and arrange professional inspection.
• Keep the outlet from touching dirty surfaces. Contamination at the outlet can affect the cleanliness of dispensed water.
• Keep children away from the appliance and do not allow unsupervised use.
• Never modify the appliance, cartridge connection, electrical system, or tubing.
• Do not open or repair the appliance yourself. Electrical and internal repairs require a qualified professional.
• Keep the plug and hands dry before connecting the power cord.
• Confirm that the supply is 230 V / 50 Hz and that the outlet is rated above 10 A before plugging in the appliance.
• If the power cord is damaged, have it replaced by a qualified electrician.
• Disconnect the plug when the appliance will remain unused for an extended period.

Setup and Operation

Install the Collection Container and Cartridge

1. Place the collection container directly in front of the main housing.
2. Insert the filter cartridge into its mounting position.
3. Turn the cartridge clockwise until it is secured.

Fill the Feed-Water Tank

1. Raise the feed-water tank handle.
2. Pull the tank out of the appliance.
3. Open the tank cover and add drinking water up to the maximum-level mark.
4. Close the cover and return the tank fully into the appliance.

Connect the Power

After checking the electrical supply, insert the dry power plug into the outlet. Position the cord so it cannot be pulled, pinched, or exposed to water.

Control Panel Functions

• Formula selection: Selects the 45 °C dispensing mode.
• Room-temperature selection: Selects water at approximately 25 °C.
• Continuous-operation button: Used for continuous operation and for resetting the cartridge after replacement.
• Child-lock button: Unlocks hot-water dispensing before selecting formula, tea, or boiling water.
• Tea selection: Selects the 85 °C dispensing mode.
• Boiling-water selection: Selects the 100 °C dispensing mode.
• Temperature-selection button: Cycles through the available temperature levels.
• Dispense button: Starts water delivery.
• Temperature display: Shows the selected temperature.

Dispense Water

1. Confirm that the feed-water tank contains water and is seated correctly.
2. Press the temperature-selection button or the appropriate temperature mode.
3. For formula, tea, or boiling water, press the child-lock button first.
4. Press the dispense button to start delivery.
5. The appliance stops automatically after dispensing 250 ml, or you can press any button to stop the flow sooner.

Indicators and Automatic States

• Water-production indicator: Illuminates while the appliance is producing purified water. If the feed-water tank is full and no control is used for two minutes, the system enters standby mode.
• Water-shortage indicator: Shows that the purified-water tank does not contain enough water. The appliance sounds three beeps, and only room-temperature water remains available.
• High-temperature lock during shortage: If a high temperature was selected when water became insufficient, that setting remains unavailable until the purified-water level is restored.
• Missing feed-water tank: The shortage indicator illuminates and the appliance switches off automatically.
• Empty feed-water tank: The pump may run for about 15 seconds before stopping.
• Filter-life indicator: Five illuminated bars represent the remaining cartridge life. Fewer bars appear as the cartridge becomes depleted. When all bars flash together, replace the cartridge.
• Child-lock indicator: Shows when the child-lock function is active.

Cleaning and Maintenance

Rinse the appliance and cartridge regularly as part of normal maintenance. Keep the tanks, outlet, and collection container clean, and prevent the outlet from contacting contaminated surfaces.

Replace the filter cartridge according to water quality and usage. The recommended cartridge service period is approximately three to six months, but heavy use or poor feed-water quality may shorten this interval. A clogged or overdue cartridge can reduce filtration performance.

Replace the Filter Cartridge

1. Remove the feed-water tank.
2. Turn the used cartridge 90 degrees counterclockwise.
3. Pull the cartridge out of the appliance.
4. Insert the replacement cartridge into the mounting position.
5. Turn the new cartridge 90 degrees clockwise until secure.
6. Reinstall the feed-water tank.

Reset the Filter Indicator

1. Switch on the appliance after installing the new cartridge.
2. Press and hold the continuous-operation button and dispense button together for three seconds.
3. Release the buttons after the beep confirms that the cartridge indicator has been reset.

Troubleshooting

The Alarm Sounds and the Water-Shortage Indicator Is On

Check whether the feed-water tank or purified-water tank is empty. Refill the feed-water tank and make sure it is fully and correctly positioned.

The Appliance Produces Water but Does Not Dispense It

The cartridge may be blocked or incorrectly fitted. Remove and reinstall it correctly. Replace it if the cartridge has reached the end of its service life or remains clogged.

The Appliance Does Not Heat Water

A circuit fault, heating-tank fault, or control-board fault may be present. Stop using the appliance and arrange inspection and repair by a qualified electrician.

Error Code E1 Appears

E1 indicates a problem with the temperature sensor or NTC probe. Do not disassemble the appliance; have the sensor checked by a qualified professional.

Disposal

The crossed-out wheeled-bin symbol means that the appliance must not be discarded with ordinary household waste. Dispose of the electrical system through an appropriate electrical and electronic equipment collection or recycling service in accordance with local regulations.

Correct recycling helps recover materials and reduces the environmental and health risks associated with improper disposal.
