Do not use this filter with microbiologically unsafe water or water of unknown quality unless it has been adequately disinfected before or after filtration.

• If water supply does not meet the requirements, service life of membrane and/or pre-filter cartridges may be shortened.
• If your home is supplied with raw well water,  perform laboratory test of your water before installing a reverse osmosis filter. If any of your water indices exceed the limit, consider using a water treatment system to correct supply water quality. Refer to water treatment specialists or companies for advice and proper equipment selection.

If the water quality requirements for free chlorine and turbidity exceed the requirements for the water supplied to the RO filter, it is recommended to install Eco soft in-line filter FDPP3P0110/G118 with dual gradient PP sediment filter and activated carbon cartridge.

UNPACKING AND INSPECTION

1. Carefully unpack the system.
2. Inspect the contents for damage. Do not open the sealed component package.
   Important: The manufacturer does not accept claims if the package is opened.
3. In case of missing parts or damage, contact the seller immediately.

INSTALL FEED WATER CONNECTION

Ensure the filter is connected only to cold tap water.

1.  Shut off the cold water valve at the entrance to the apartment and open the sink faucet to release pressure from the system. Then, close the faucet.
   • To connect to a 1/2’’ cold water feed line, it is sufficient to install a tee in the feed line.
   • If you have a 3/8˝ connection, use the additional adapters included in the kit.
2. Install the feed water adapter in the cold water pipe.
3. Tighten the nut by hand, then use a wrench for added security.
4. Cut the required length of the tubing, connect it to the feed water adapter and use fixing clip.

INSTALLATION OF THE LEAK SENSOR

1. Attach the adhesive stickers to the surface.
2. Install the leak detector element in the space marked.
3. Place the leak detector on the stickers.
4. Connect the tube from the feed water adapter to the sensor.
5. Cut the tube and connect it to the sensor.
6. Connect the tube to the «Feed» panel and secure the tube with the clips for reliable fixation.

DRAIN CONNECTION

1. Drill a 5 mm hole in the drainpipe.
2. Install the sealing gasket with its adhesive side facing the pipe.
3. Attach the drain clamp, ensuring the hole in the pipe aligns with the clamp’s fitting.
4. Attach the drain clamp, ensuring the hole in the pipe aligns with the clamp’s fitting.
5. Insert the tube into the drain fitting.
6. Connect the tubing to the «Drain» port on the filter and secure it with a fixing clip.

DRINKING FAUCET CONNECTION

1. Drill a 12.5 mm hole in the countertop or sink.
2. Assemble the faucet on the countertop or sink.
3. Insert the quick-connect fitting into the faucet pipe and secure it with a clip.
4. Cut the required length of tubing and insert it into the quick-connect fitting, securing it with a clip.
5. Connect the tubing to the «Drink» port on the connection panel and secure it with a fixing clip.

FIRST FILTER START-UP

1. Open the cold water supply valve.
2. Open the purified water facet.
3. Connect the power adapter to the power outlet on the connection panel. A short beep will sound, and three indicators will light up in blue. The filter will automatically flush for 18 seconds.
4. Flush the filter for an additional 10 minutes by opening the purified water facet. Indicators 1 and 3 will stay on, while indicator 2 will blink. After 10 minutes, close the purified water facet.
5. Check all connections for leaks by wiping them with a paper towel. Ensure that all tubing is securely connected.
6. Close the purified water facet and make sure the faucet is not leaking. The filter installation is complete.

CARTRIDGE REPLACEMENT GUIDE

Before starting:

1. Close the cold water valve at the system inlet.
2. Unplug the filter by disconnecting the power adapter.

REMOVING THE USED CARTRIDGE

1. Open the safety lock.
2. Remove the used cartridge and dispose of it properly.

INSTALLING THE NEW CARTRIDGE

1. Unpack the new cartridge.
2. Remove the protective caps (if present).
3. Insert the cartridge fully into the slot.
4. Secure the cartridge and close the safety lock.

FILTER STARTUP

1. Open the cold water supply valve.
2. Open the purified water facet.
3. Connect the power adapter to the power outlet on the connection panel. A short beep will sound, and three indicators will light up in blue. The filter will automatically flush for 18 seconds.
4. Rinse the filter for a further 10 minutes by opening the purified water faucet. Indicators 1 and 2 will remain on and indicator 3 will flash. After 10 minutes, close the purified water faucet
5. Check all connections for leaks by wiping them with a paper towel. Ensure that all tubing is securely connected.
