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 Bottle-Free Water Dispenser is based on Reverse Osmosis System and is a perfect source of crystal clear
cold, warm and hot water to be installed at home or office. You have now become the owner of the highest quality
Water Distributor, which will provide you with crystal clear water without the necessity to use water bottles.
Additionally, New Line Molecular Reverse Osmosis System assures perfect water treatment based on the
innovative technology and German licence. New Line system reduces the majority of impurities present in water,
such as rust, silt, chemical compounds, bacteria, viruses and many others.
Water Dispenser uses water pressure provided by the water mains. Raw water flows through prefilters and
reverse osmosis membrane, which remove all impurities. Then, purified water is saturated with minerals received
from carefully sellected natural dolomite stones. Next, water goes to water tanks, where it is stored, and dirty
water is directed to the drain.
Please read the Instruction Manual carefully and follow all guides while installing.

1. BEFORE YOU INSTALL THE BOTTLE-FREE WATER DISPENSER
CAUTION: Do not push the “HOT POWER” button until the main water tank is filled with water.
CHECK RAW WATER INLET: COLD raw water must fulfill certain conditions. Please refer to the
specificaton outlined on p.8. If raw water does not fulfill the required technical parameters, then the
Moelcular Reverse Osmosis system will not work properly and cartridges and membrane lifetime may be
substantially reduced.
CAUTION: Chlorine dissolved in water may severely damage the membrane. Prefilters remove chlorine
only to the level given on p.8. It is essential that one carries out periodical prefilter exchange and service
of the whole filtration system. Please refer to WATER DISTRIBUTOR SERVICE AND MAINTENANCE
described on p.16-17.
CAUTION: Rinse the membrane and postfilters before the first use. Membrane is protected by a food
preservative, which must be washed out before the first water consumption from the Water Distributor.
For details please refer to p.13.
2. SAFETY ISSUES

4. OPERATING FUNCTIONS OF WATER DISPENSER EQUIPPED
WITH AN RO SYSTEM
4.1 WATER FILTRATION
Sediment cartridge (prefilter) –STAGE 1
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.
Sediment cartridge (prefilter) –STAGE 2
This prefilter has a replaceable meltblow or yarn sediment cartridge. This is the 2nd stage of the system with the
higher gradation than 1st.
Activatedcarboncartridge (prefilter) –STAGE 3
Activated carbon cartridge use the ability to absorb chemical pollutants in the activated carbon. Used for improving
the quality of drinking water. Water flows through the entire filter bed for maximum absorption of pollutants.
Activated carbon cartridge improve the taste and smell of water, reducing organic impurities, chlorine and its
poisonous derivatives, eliminate lead and other toxic heavy metals.

Reverse Osmosis Membrane –STAGE 4
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.
Inline Activatedcarboncartridge (postfilter) –STAGE 5
This postfilter improves water taste and smell.
Inline Mineralizingcartridge (postfilter) –STAGE 6
Mineralizing cartridges saturate water with mineral salt ions. The appropriate dissipation of minerals contained
in the cartridge filling causes their dissolution in water.
4.2 TANK FILLING
There are three tanks in Water Distributor CW-929:
A. Cool water tank ~ 8 l capacity
B. Hot water tank ~2 l capacity
C. Cold water tank ~ 4 l capacity
Filtered water enters cool water tank A, then goes to hot water tank B and cold water tank C. Check valve is
installed between the cool water tank and hot water tank, which prevents hot water from going back to the cool
water tank. When the tanks are filled with water, hydraulic floating valve shuts off water supply to cool water
tank.
4.3 WATER COOLING SYSTEM
Water cooling system contains the following elements: compressor, condenser and steamer. A freon-free
refrigerant R134 circulates in the cooling system. In order to keep temperature on the same low level thermal
insulation is used in cold water tank.
4.4 FLOW RESTRICTOR
Flow restrictor is located on the line before drain saddle. Is is used to regulate pressure and sewage volume after
the purification process.

7. 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.
7.1 Connecting standard the QC push-in fitting
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.
7.2 Disconnecting standard the QC push-in fitting
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.

8.2 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 8.2.2 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 flow restrictor valve.
