RO-DTF600 Direct Flow Water Purifier
Product Information:
The AMI Direct Flow is an under-the-counter tankless RO (Reverse
Osmosis) water purifier. It is a single cabinet design that
provides high-quality, clean, filtered drinking water right from
your sink. The system is equipped with AMI Ultra-High Flow RO
Membrane, which produces water on demand without the need for a
storage tank. It is designed for quick and simple installation and
maintenance.
The system consists of three powerful stages of water
treatment:
-
Stage 1: Sediment Filter: This five micron
filter removes dirt, sand, rust, grit, and other suspended sediment
from the water. -
Stage 2: Carbon Filters: The water passes
through two carbon filters to remove chlorine, chemicals, bad
tastes, and odors. -
Stage 3: Reverse Osmosis Membrane: The heart
of the system, the reverse osmosis membrane, removes up to 99.9% of
total dissolved solids in the water. It works on a molecular level,
separating pure water from impurities and flushing the impurities
down the drain.
The product features include a compact single cabinet design for
under-the-counter placement, fully automatic operation with
auto-on/off function, suitability for brackish/tap water/municipal
water supply, a feed water booster pump to optimize water flow and
quality, and compatibility for both under-the-counter and
side-by-side placement adjacent to a refrigerator. The high flow
direct flow RO technology eliminates the need for a tank, making
the design compact and space-saving.

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.
Collet
· 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.

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.
