Complete Water Treatment in 3 Powerful Stages

• Stage 1: Sediment Filter: First the water passes through a five micron filter which removes dirt, sand, rust, grit, and any other sediment suspended in the water.
• Stage 2: Carbon FilterS: Next, the water passes through two carbon filters to remove chlorine, chemicals, and bad tastes and odors from your water.
• Stage 3: Reverse Osmosis Membrane: The final stage is the reverse osmosis membrane, which is the heart of the RO system that removes up to 99.9% of total dissolved solids in your water. The RO membrane works on a molecular level – separating the pure water from the impurities and flushing the impurities down the drain.

About Quick Connect Fittings

AMI Direct Flow is equipped with quick-connect fittings throughout the system to make installation and maintenance simple and fast. Before beginning installation, take a few moments to familiarize yourself with how to properly connect and disconnect tubing to quick-connect fittings.

• Cut tubing with the end square with a blade against a flat surface, or use a tube cutter. An angled cut or distortion of the tubing will not provide an efficient seal and may cause leaks.
• Remove blue locking clip from fitting before installing tubing. Push down on the fitting collet and remove the plug. Keep the clip. The plug may be discarded.
• Push the tubing into the fitting, to the pipe stop. The collet (gripper) has teeth which hold the tubing firmly in position while the ‘O’ Ring provides a permanent leak proof seal.
• Check the Seal: Pull on the tubing to check it is secure. It is good practice to test the system prior to leaving site and/or before use.
• Replace blue locking clip after tubing is installed.
• To Disconnect: Ensure system is depressurized before removing fittings. Remove the locking clip. Push in the collet against the face of the fitting. With the collet held in this position the tube can be removed. The fitting can then be re-used.

Installation Instructions

AMI Direct Flow is a user-friendly under-the-counter model recommended for installation under a kitchen sink but can be installed near any cold water supply meeting the below installation site recommendations.

• Electrical Outlet no more than 9ft. from the point of installation
• Cold Water supply line with ½” inch nipple, no more than 9ft. away. (If your supply line is 3/8”, an adapter will be necessary.)
• Drain pipe for reject water, no more than 9 ft. away.
• Installation space as per the dimensions of the purifier
• Countertop with pre-drilled 1/2” hole for installation of the faucet.
• The system and installation need to comply with state and local laws and regulations

System Connections

All of the system connections are in a panel located on the back of the unit.

1. Purified Water – 1/4” White Tube. Connect to the faucet.

2. Reject Water – 1/4“ Blue Tube. Connect to Drain.

3. Water In – 3/8” White Tube.
   Connect to Cold Water Supply.

4. Power Supply – Plug into electrical outlet. (Do this last)

Feed Line Installation Instructions

• Apply thread tape to the SS ball valve and thread into the ¼ e ¼ inch port of the 3-way connector as shown in the figure.
• Connect the 3-way connector to the raw water supply as shown in the figure. The threaded end of the 3-way connector is fit in–line with the cold water supply.
• Now connect one end of the white 3/8” tube to the SS ball v aallvvee and other end to the pushfit elbow fitting on the back side of the of the purifier labeled ‘Raw Water’ (#3 in the above diagram).

Drain Line Installation Instructions

• Select a location for the drain hole based on the design of the plumbing. It should be installed above the trap and on the vertical or horizontal tail piece. To avoid possible drainage noise, mount drain line as low as possible on the vertical tailpiece. Do not install downstream of a garbage disposal, as this can cause contamination and system fouling.

• Place the self-adhesive black foam square over the hole, making sure the holes match.

• Place one half of the plastic drain saddle assembly on each side of the drain pipe with the fitting, and clamp loosely using the nuts and bolts included.

• Align the hole drilled in the drain pipe with the hole in the drain saddle. Make sure to align the drain saddle hole to the drilled hole perfectly. A drill bit or other long narrow object may be used to help align correctly.

• Use Phillips screwdriver to tighten the clamp. Avoid over-tightening.

• Install one end the blue tubing to the drain saddle fitting, and the other to the system connection marked Reject Water’ (#2 on the page 6 diagram).

Faucet Installation Instructions

• Install the faucet , faucet base and large black washer on top of the counter, and inserting the threaded pipe through the pre-drilled 1/2” hole.

• From beneath, thread on the washers and lock nut to secure the faucet to the counter. Check the positioning then tighten the lock nut with a wrench.

• Slide the compression nut then sleeve onto one end of the ¼“ white tube. Insert the tubing insert into the end of the tubing. Slide the tubing (until it stops) into the faucet stem and screw it in by hand with the nut

• Connect the other end of the tubing to the system care fitting labeled ‘Faucet’ (#1 on the page 6 diagram).

Starting-up the Purifier

• Before plugging in the power supply, open the feed inlet ball valve (the handle will be parallel to the feed line) to start the flow of water into the purifier. Open the faucet and wait for 1-2 minutes while the unit fills with water and the air is purged.
• Plug in and switch on the power supply.
• Let water flow for first 5 mins to flush the filters.
• Close the faucet.
• The purifier is ready to use.

Important Safety Instructions

• If the supply cord is damaged, it must be replaced by the original part in order to avoid hazard.
• Only use this system on potable water supplies. Do not use this system where the water is microbiologically unsafe or of unknown quality without adequate disinfection before or after system.
• Excessive incoming water pressure can cause leaks, flooding and property damage. It is highly recommended to monitor your home’s incoming water pressure over a period of 24 hours to determine if a pressure regulator is required.
• Manufacturer assumes no responsibility for damages incurred through improper installation or use of these products. Incorrect installation or operation will void the warranty.
• Do not use copper fittings or tubing on RO product water. Due to the high purity, it can leach the minerals from copper tubing and develop pinhole leaks over time.
• Please TURN OFF the main cold water supply to the RO system when the unit is not in use during a vacation or extended leave. During very cold or freezing weather conditions, please also TURN OFF the main cold water supply and completely drain all of the water from the RO system and water storage tank.
• Never use hot water or allow the unit to freeze.

Maintenance

Regular system maintenance is required to ensure optimum performance.

• Sediment & Carbon Filter: Replace Every 3-6 months
• Membrane Element & Flow Restrictor: Replace Every 12 months

This recommended replacement schedule is for average feed water quality, and service needs will vary based on water quality and use.

• For cleaner city water less frequent change-outs may be sufficient as long as there is no loss of performance.
• For applications where the feed water is dirtier or has specific issues, more frequent change-outs may be required.
• Generally speaking, filters should be changed when there is a loss of performance and after any extended periods of non-use.
• For extended periods of non-use, ensure that you have disconnected the power supply and turned off the water supply.

Filter & Membrane Changing Instructions

Note: If your RO system is connected to an icemaker or other equipment, you must turn off the connection to the equipment before performing any maintenance.

1. Before starting, disconnect the power supply and shut off the cold water supply to unit by closing the feed valve. Open the RO faucet to drain and decompress the system. Leave the faucet open and the cold water supply closed until the filter change is complete.

2. Using a phillips-head screwdriver, remove the three screws on the rear of the enclosure and remove the back and top sections of the enclosure. If the zip tie securing the filters together for shipping is still present, this can be removed and discarded before continuing.
   Take note of the flow arrow direction on each of the filters before removing them from the system

3. Remove the sediment filter: On the fitting at the end of the filter body: remove the blue locking clip from beneath the collet. With one hand, press the collet down toward the filter and hold it down while pulling out the elbow fitting. (Reference page 5). Repeat this process on the other end. Remove the filter from the mounting clips by holding the base of the clip in one hand and pulling with a sharp tug. Repeat for the second clip.

4. Replace the sediment Filter: Snap the new filter into the clips, taking care to make sure flow arrow is pointing in the same direction. Remove the locking clip from beneath the collet. Press the elbow fitting in to the pipe stop. Tug on the fitting to ensure it is secure. Replace the Locking Clip.

5. Repeat these steps with both of the carbon filters to complete the filter change.
   (If you are not replacing the membrane or flow restrictor at this time, you may skip to step 9)

6. Locate the feed end of the membrane housing (the end with only one connection). Remove the locking clip from the feed elbow fitting and disconnect the tubing. Remove the cap of the housing by twisting counter-clockwise. Using pliers, pull out the old membrane from the housing.

7. Remove the new membrane from its bag. Insert the membrane in the housing in the same direction as the old membrane and push it firmly into the housing until it seats on the far end. Screw the housing cap back on, making sure the o-ring is positioned correctly. Reconnect the tubing and tug to make sure it is secure. Replace the locking clip.

8. Locate the flow restrictor mounted on the blue tube between the membrane and the drain line, taking note of the direction of the flow arrows. Remove the locking clips and press in on the collets to release the tubing. Replace with the new flow restrictor, ensuring the flow arrow is pointing toward the drain, tug to ensure a tight seal, and replace the locking clips.

9. Double-check all connections and prepare to restart the system. Leaving the faucet open, slowly open the feed valve and allow water to purge air from the system for several minutes. Plug in the power supply and allow the unit to flush for 5 minutes before closing the faucet. Check for leaks and reseat tubing where needed. Once proper operation is verified, reassemble the enclosure, fastening with the three screws in the back.

Technical Specifications
