Feed water valve and T-piece · Install the T-piece and feed water valve according to the diagram. · Wrap the threads of the feed water valve and T-piece with sealing tape. · Connect the white feed water hose from the device to the feed water valve.
· Install the feed water valve. · Install the T-piece of the feed water valve and then connect the mains water. · Attention! The water supply to your device must come from the cold-water line. Note! Use only cold water, as hot water can damage your device. Softened feed water extends the life of the reverse osmosis membrane.
Installation of the wastewater clamp · Place the wastewater clamp on the drainpipe above the siphon and tighten it. · Using the wastewater clamp as a guide, drill a 6 mm hole that is sufficient to pass the ¼ hose through one side of the drainpipe. Do not drill through both sides. · Connect the red wastewater hose from the device to the wastewater clamp.
Attention! · Cut the pipes cleanly and at right angles. Otherwise, poor connections and potential leaks may occur. · The lowest point of the pipe should be the connection point at the wastewater clamp. The pipe should not sag, as this can cause excessive noise when the wastewater flows to the drain.

Flushing the prefilters (first installation, before installing the reverse osmosis element)
Prepare the system for operation by flushing the prefilters:
1. Disconnect the inlet hose of the reverse osmosis element from the element housing cap. Open the water line and inlet valve and let the system run through the 3 prefilters.
2. Direct the output water into a container or drain. 3. Continue flushing until the output water is visibly clean. Reconnect the hose. 4. Note: The pump and membrane can be severely damaged if the system is not flushed through
the prefilters. Discard all water from the flushing process as it is not suitable for use or consumption. 5. After flushing the prefilters, connect and open all valves. 6. Wait about 2 min before opening the faucet. 7. Allow the system to flush for the first 10­15 min with the faucet open. Do not use any water from the reverse osmosis device at this time.
Flushing the pressure tank
1. After flushing the prefilters, operate the device and let the pressure tank fill. 2. It takes approximately 45 min for the tank to fill. Once the tank is full, drain the pressure tank by
leaving the faucet open. 3. Once the tank is completely empty, close the faucet and let the tank fill again. 4. After flushing the pressure tank, the device is ready for use.
Regular operation
Once the system is set up and connected to a power source, it will automatically start water treatment when the faucet is opened. When the faucet is closed, the device will automatically shut off. After use, the device will automatically flush if it is equipped with an automatic flushing function.
Filter maintenance
To ensure optimal operation of the device, regular maintenance is required. The frequency of maintenance depends on the quality of the raw water and the intensity of system use. Here are some guidelines for scheduled filter replacements, though the frequency of filter changes may vary. If unsure, please contact a service technician.
1. Replace the PP filter every 3­6 months or as needed. 2. Replace the carbon block filter every 6­12 months or as needed. 3. Replace the reverse osmosis membrane every 18­24 months or as needed. 4. Replace the inline carbon filter every 6­12 months or as needed.
If you are away for an extended period or will not be using the device for a long time, disconnect the device from the power source. When the device has been shut down and not used for an extended period, perform the same flushing procedure as during initial start-up.
