WATER FILTRATION SYSTEM (RO5)
OWNER’S MANUAL

INTRODUCTION
Congratulations on choosing Permatech to improve the quality of your water. You will immediately notice the
numerous benefits of having quality water in your home or office.
This system uses household water pressure to reverse a natural physical process called osmosis. Water under
pressure is forced through a semi-permeabe membrane where minerals and impurities are filtered out. Clean
drinking water goes to the faucet or storage tank, while the impurities are sent to the drain. These impurities are
measured in water as Total Dissolved Solids (TDS).
The system includes innovative and patented replaceable prefilters and postfilter, convenient postfilter cartridge.
The prefilters remove sediment and chlorine from the water supply before they can enter the RO membrane.
The postfilters remove any taste or odours that may remain in the water after passing through the RO membrane,
and just before going to the RO faucet. To prevent water waste, an automatic shut-off valve closes when the
RO faucet is closed and the storage tank is full.
This reverse osmosis system will provide you with a continuous supply of clear, delicious water for drinking,
cooking and other uses. Having high quality RO water at hand eliminates the need to buy bottled water. The
storage tank holds up RO water for your needs.
Standard filtration system includes a pressure tank with a volume of 12 liters.

1. BEFORE YOU INSTALL RO SYSTEM
CAUTION: A refrigerator icemaker may not operate properly when connected to RO system that has
been installed on a water system which operates outside of the specified pressures listed on page 6.
CHECK YOUR WATER SUPPLY: The cold water supply to the RO system must be within certain quality
limits. See the specifications on page 6. If the supply water is not within the limits defined, the RO
system will not produce water as it should and substantially reduced filter and membrane life will result.
CAUTION: Chlorine in water will destroy the RO membrane. Most cities add chlorine to water supply to
kill bacteria. The prefilters will remove the chlorine up to the limits shown in the specifications on page
6 before it enters the RO membrane. It is important to replace the prefilter cartridges at the
recommended time intervals. See System Care and Maintenance starting on page 13
CAUTION: Before consuming any water from the RO system you must purge the RO membrane
cartridge. The RO cartridge contains a food grade preservative that should be removed before
consuming the water from the system. This procedure is explained on page 14.
2. SAFETY CONDITIONS
Read all steps and guides carefully before installing and using your reverse osmosis system. Follow
all steps closely to install correctly. Reading this manual will also help you get all the benefits from
your RO system.
DO NOT attempt to use this product to make safe drinking water from non-potable water sources. Do
not use the system on microbiologically unsafe water, or water of unknown quality without adequate
disinfection before or after the system. This system is suitable for cyst reduction and may be used on
disinfected water that may contain filterable cysts.
Check with your local public works department for plumbing and sanitation codes. You must follow
their guides as you install the system.
This reverse osmosis system works on water pressure of 2,2 bar (32 psi) (minimum) to 6 bar (87 psi)
(maximum). You must install a pressure reducing valve in the water supply pipe to the reverse osmosis
system if the water pressure exceeds 6 bar (87 psi).
DO NOT install this reverse osmosis system outdoors or in extreme hot or cold environments.
Temperature of the feed water supply to the RO system must be between 2° C and 38° C. Do not
install on hot water.

3. HOW YOUR RO SYSTEM WORKS?
Connection scheme and the list of parts of the filtration system are on page 17.
Prefilter Heavy duty Sediment cartridge
Water from the cold water supply pipe enters the filter through sediment cartridge first. Sediment cartridge is
the best solution to remove mechanical impurities such as: sand, fluvial silt, rust and other sediments that you
may or may not be able to see in your water.
Prefilter Sediment & activated carbon cartridge
Activated carbon removes chlorine and its derivatives, lead, toxic metals construction, pesticides, detergents,
phenols and organic compounds. Twine polypropylene removes minor mechanical impurities.
Reverse Osmosis Membrane
The RO membrane is a tightly wound special membrane. The membrane removes the dissolved solids such as
calcium carbonate, chlorides, nitrates etc. and organic matter when the water is forced through the cartridge.
High quality product water exits the RO cartridge and goes to the storage tank or to the postfilter and RO faucet.
Rejected water with the dissolved solids and organic matter is routed through the flow control valve and to the
drain.
Postfilter Activated carbon cartridge
Activated carbon cartridge improve taste and smell of water.
Postfilter mineralizing cartridge
Mineralizing cartridges saturate water with mineral salt ions. The appropriate dissipation of minerals contained
in the cartridge filling causes their dissolution in water.
StorageTank
The storage tank will hold pure water. A diaphragm inside the tank keeps the water pressurized to about 2,6 bar,
when the tank is full. This pressure provides a fast flow to the RO faucet. The tank, when empty is pressurized
to 5-7psi (0,3-0,5 Bar).
Automatic shut-off valve
To conserve water, this drinking water system has an automatic shut-off valve system. When the storage tank
is filled to capacity and the RO faucet is closed, pressure closes the shut-off valve to stop the flow to drain.
Pressure in the storage tank is about half of the water supply pressure. Alter drinking water is used, and pressure
in the system drops, the shut-off valve opens to allow water to flow again.

5. WHERE CAN RO SYSTEM BE INSTALLED?
This RO system is designed for installation under the sink, usually in the kitchen or bathroom.The RO system
can be mounted on a wall surface or can lie on the cabinet floor next to the storage tank. The RO faucet installs
on the sink, into the counter next to the sink or in the special bracket on the wall.
You can also install the system in any remote location from the faucet, observing the safety guides on page 4.
You will need a nearby water supply and drain point.
Water supply: To provide supply water to the RO system, use the included feed supply fittings as described on
page 8.
Drain Point: A suitable drain point is needed for the reject water from the RO membrane. A floor drain, laundry
tub, standpipe, sump, etc., is preferred for remote installations. A saddle drain adapter is included to install the
system under the sink where codes permit, as an optional drain point.
NOTE: Tubing lengths supplied with the system allow for the easy moving of the filter assembly for servicing. lf
tubing lengths are shortened for a neater appearance, it may be necessary to keep the filter assembly in its
installed location for service. Please keep connecting tubes as long as possible for convenient usage.

6. USEFUL INSTALLATION TIPS
Filter System uses Quick Connection type style fittings. These fittings only require you to simply push
the tubing firmly into each fitting.
6.1 Connecting standard the QC push-in fittings
1. Remove yellow locking clip from the fitting.
2. Push the pipe into the fitting, until you fell resistance. The collet (gripper) has stainless steel teeth
which hold the pipe firmly in position whilst the o-ring provides a permanent leak-proof seal. Pull on the
pipe to check whether it is secured. It is a good practice to test the system prior to leaving the site and/or
before use.
3. Place the yellow locking clip back to lock the pipe and prevent it from accidental slip-out.
6.2 Disconnecting standard the QC push-in fittings
Make sure that the system is depressurized before removing fittings.
1. If present, remove locking clip from the fitting.
2. Push in the collet against the face of the fitting. With the collet held in this position the pipe can be
removed. The fitting can then be re-used.
7. SYSTEM INSTALLATION
7.1 STEP 1: INSTALLATION AT COLD WATER INLET
7.1.1 3/8” water feeder – installation at water inlet
Water feeder connection set
(1 - connector element 3/8" , 2 – ball valve)

9
1. Locate the cold water valve under the kitchen sink (if water feeder is to be installed behind the valve) or main
shut-off valve, and then turn off water inlet. Open the cold water tap in the faucet in order to release the remaining
water.
2. Unscrew the nut on the installation tube or shut-off valve. Put on rubber gasket and mount the water feeder
element. Tighten firmly.
3. Screw in the ball valve into the water feeder element.
4. Install the connection tube to water feeder element or mount the shut-off valve.
5. Close the ball valve and then open the main shut-off valve or cold water inlet valve in order to check for
possible leakages.
6. Use teflon tape to seal th threaded connections.
7. Connect the ball valve with the connector „Feed water” by the use of 1/4” elastic tube, which is included in the filter
set.
7.2 STEP 2: INSTALLING THE FAUCET
The faucet should be positioned with aesthetics, function and convenience in mind. A flat surface is required for
the faucet base so that it can be installed firmly. Also, check the under sink area of the desired location to see if
there is enough space to complete the faucet installation.
If the space is not available on the upper sink area, the faucet could be positioned on the counter top at the
edge of the sink. Be sure to watch for obstructions below, i.e., drawers, cabinet walls, support braces, etc. If the
counter top is made of ceramic tile, the method for drilling the holes should be the same as for porcelain sink.
NOTE: The sink drilling process, although not complicated, requires a certain amount of caution and
forethought. A porcelain sink can crack if care is not exercised.

10
7.2.1 DRILLING HOLE IN A PORCELAIN ENAMEL/ STAINLESS STEEL/ALUMINIUM SINK
A Ø 13mm hole is required for the faucet. It is recommended that you obtain a special ceramic drill bit for a
porcelain and/or tile sink/counter. When drilling the faucet hole for the sink/counter, you should wear eye
protection and exercise caution by following the below steps carefully.
1. Place a piece of masking tape or duct tape on the determined
location where the hole is to be drilled.
2. Use a variable speed drill at slow speed with Ø 6mm drill bit,
and drill a centering hole in the center of the desired faucet
location. Use lubricating oil to keep the drill bit cool while
drilling.
3. Enlarge the hole using a Ø 10mm drill bit.
4. Enlarge the hole using Ø 13mm drill bit. Keep bit well oiled
and cool, then drill slowly.
5. File or clean the surrounding area and then remove the
masking or duct tape. (NOTE: the metal chips on porcelain
will stain very fast).
6. Pass the chrome cover plate and rubber washer according to
the picture on page 10 through the threaded mounting tube at
the base of the faucet.
7. Under the sink, install the white plastic locating washer, small
metal washer and screw on the nut untill it is tight against the
underside of the sink/ counter.
8. With all fittings in place, thread the Tube Fastening Nut and
Collet, insert the tubing into the faucet inlet and tighten the nut.
9. Connect the other free ends of the 1/4” tubing to the connector
„Faucet” and „Faucet mineral” on the filter. Please refer to
connection schemes on page 17.

11
7.3 STEP 3: INSTALLATION OF DRAIN SADDLE
1. Drain saddle fits the majority of standard Ø 50 mm sewage pipes. Drain saddle should be mounted
above the siphon trap on the vertical or horizontal pipe under the sink drain.
2. Remove the nuts and bolts from the front half of the saddle, position and hold it in the desired location
on the drain pipe above the siphon trap and water line and mark the spot for drilling with a Ø 4 mm drill
bit or awl through the whole in the clamp. Do not mount the drain saddle near the garbage disposal, as
this may cause the drain line to clog. You should carefully consider the route and available space for
the 1/4” drain line tubing before you drill the 1/4” hole.
3. Drill a Ø6 mm hole in the location marked in point 7.3.2 into the drain pipe and clean the surface of the
pipe.
4. Remove the paper protection and round inner part from the foam gasket that is included in the set. Stick
it to the drain pipe exactly in the place where the hole in gasket covers the hole in the pipe.
5. Allign the drilled hole in the drain pipe with the front half of the drain saddle using a Ø 4 mm bit or a
narrow screwdriver. Now locate the complementary piece of the drain saddle assembly clamp and join
them together with the bolts. Tighten the two bolts evenly.
6. Connect 1/4” tubing to the drain saddle and the other free end to the connector „Drain” on the filter.

12
7.4 STEP 4: MOUNTING THE TANK BALL VALVE
NOTE: Do not tamper with the air valve on the lower side of the storage tank. It has been preset to 0,3-
0,5 bar (5-7 psi) at the factory.
1. Unplug the plastic cap on top of the tank if present.
2. Connect the ball valve to the thread. Hand-tighten only. Do not use a wrench or overtighten it.
3. Connect the other free end of the 1/4” white tubing to the tank fitting.

1. Check all tubing to be sure there are no kinked.
2. Turn the Storage Tank Valve to OFF position.
3. Turn RO faucet lever to continuous flow ON position (handle pointed up).
4. Turn the cold water supply main valve on slowly. When the system is pressurized, check for leaks.
5. You will hear the air purging from the system and within 5 minutes, the water should start dripping
from RO faucet. Once the water starts to drip, allow 20 more minutes for the water to flow through the
system and purge all the air trapped inside the system.
6. After 10 minutes, turn the Storage Tank Valve to the ON position (handel is parallel to the tubing).
7. Turn the RO faucet handle to the OFF position. Now the purified water will start going into the storage
tank.
CAUTION: You must purge the first two tanks of water from the system prior to consumption of the
product water. Do not drink the first 2 tanks of water produced by the system!
8. Allow the storage tank to fill for 2 hours. Then open the faucet untill the tank is empty and the flow just
drips from the faucet.
9. Close the faucet and allow the storage tank to fill again for 2 hours. Then open the RO faucet and empty
the tank again. After discharging the contents of the Storage Tank twice, you can start enjoying the pure
water.
NOTE: Check for leaks daily for the first week after installaion.
8. SYSTEM CARE AND MAINTENANCE
