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.

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.

• Apply thread tape to the SS ball valve and thread into the 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

” tube to the SS ball valve

and other end to the pushfit elbow fitting on the back side of the

purifier labeled ‘Raw Water’ (#3 in the above diagram).

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.

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.

• 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.

• 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.

Drain Line Installation Instructions

• 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).

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.

* Purification production rate based on 750 ppm TDS tap water at room temperature.

* This system is designed to work off of the standard line pressure typically found in a home on

USA municipal water. For locations with high feed pressure (over 60 psi) , a feed pressure

regulator should be installed before the system.
