Introduction

Thank you for purchasing this quality product. To minimise the risk of injury we urge that our clients take some basic safety precautions when using this device. Please read the operation instruc-tions carefully and make sure you have understood its content.
Keep these operation instructions safe.

Safety instructions

• Clean and replace the filter cartridges regularly.
• Do not disassemble parts indiscriminately; this can lead to leaks or damage.
• Do not use power supply units with an unsuitable rated voltage.
• Disconnect the mains plug and close the water tap before storing the appliance for a longer period.
• Do not store or use the appliance at an ambient temperature of 0 ℃ or below.
• Take care when installing or removing the cartridge or moving the appliance.

Other instructions

• When not in use, interrupt the water supply and close the ball valve to prevent damage from pressure surges. Uncontrolled pressure surges can lead to leaks and damage to the filter hous-ing. We accept no liability for damage caused by pressure surges.
• In the event of problems, disconnect the appliance from the power and water supply and contact a specialist. Replacing the filters may solve the problem.
• The appliance vibrates slightly during the filtering process.
• It is recommended that the cartridges are replaced by a specialist.
• If the water supply is insufficient, the indicator light lights up yellow and the buzzer sounds for 5 s
• After 50 operating hours, the indicator lights up green and the buzzer sounds for 10 s. At the same time, the system stops operating and reminds the user to replace the 3 pre-filters. The calculation of the filter service life starts after the system is switched on again.

Note!

• Before opening the faucet for the first time, make sure that the system is correctly installed and working properly. Rinse the filters for 10–15 min before taking the first glass of water for drinking.
• Allow the system to run normally for more than 90 min before carrying out a test.

Installation

Installing the ball valve and T pieces

• Install the T piece and the 3-way ball valve according to the instructions.
• Wrap the thread of the 3-way ball valve and T piece with adhesive rubber.
• Connect the water supply line (⅜″, white) from the device to the feed-water valve.
• Install the 3-way ball valve to the T piece, then connect it to the water source.

Mounting the water faucet

• Chose a suitable spot near your washbasin to install the water faucet.
• Drill a 12-mm diameter hole into the worktop.
• Install the washers, plates, gaskets, and nuts in the order shown and tighten them on the worktop.
• Fix the reverse-osmosis water line (¼″, blue) to the un-derside of the water faucet, then connect the line to the device. Attention! Make sure that the lines have been connected properly.

Installing the drain clamp

• Install the drain clamp to the drainpipe above the syphon and tighten it.
• Using the drain clamp as a guide, drill a 6-mm hole large enough to feed the ¼-inch pipe through one side of the drainpipe. Do not drill through both sides!
• Connect the drainpipe (¼″, red) from the device to the drain clamp.

Attention!

• Cut the hoses cleanly and at right angles. Failure to do so will result in poor connections and possible water leaks.
• The lowest point of the pipe should be the point where the drain clamp is connected.
• The pipe should not sag, as this might lead to excessive noise when the wastewater flows to the drain.

1. Connect the reverse osmosis system to the adapter, then the power indicator light lights up, the buzzer sounds three times, the device rinses for 90 s and the rinsing symbol flashes
2. The reverse osmosis system starts producing water and the integrated computer displays the TDS value, cartridge life and operating indicator in real time. All symbols go out when the water tank is full.
3. The water reservoir symbol flashes and buzzes 10 times if there is not enough water or the water pressure is too low. The machine rinses for 5 s if there is enough water or the water pressure is too high. 4.
4. The machine stops producing water and issues a warning message. All symbols flash and the buzzer sounds 30 times after 6 hours of uninterrupted operation or if a water leak is detected.
