Osmosis Professional 190
Turns hard tap water into soft,
highly pure aquarium water
- Please read the instructions carefully before using the system for the first time
Keep the instructions in a safe place. -
Congratulations on purchasing this high-quality osmosis system from DENNERLE. You have opted for a highly efficient,
state-of-the-art piece of aquarium equipment. If used properly you will be able to produce highly pure and clean water that
is idea for use in maintaining aquariums.
It will enable you to set the water values to match those to which the tropical fish and plants are accustomed from their
natural habitat. Osmosis water allows you to successfully keep the most demanding of fish such as discus or salt water fish.
DENNERLE wishes you lasting enjoyment from your aquarium!
Important tips
· Protect all components, especially the membrane, from sunlight, heat and frost!
· Maximum permissible operating temperature: 25 °C, for short intervals up to 30 °C.
· Required operating pressure: at least 3 bar. Maximum permissible operating pressure: 6 bar.
· The systemis designed to be used with tap water of a quality that corresponds to the European standards for drinking-
water. The system must not be operated with well water or spring water – the high iron content in the water will result
in the membrane becoming blocked within only a short space of time.
· Switch off the system while work is being carried out on the mains water supply and for several hours afterwards, as
otherwise it might suddenly become blocked by rust or other deposits that are released while work is in process.
· If the tap water is chlorinated, the system should only be used together with a fitted active carbon filter, since chlorine
may destroy the membrane.
· Do not bend the hoses. Osmosis water and residual water must always be able to drain off freely – do not close the
hoses using a faucet or solenoid valve.
· Once the membrane has been put into operation, do not allow it to dry out.
1 This is how the DENNERLE Osmosis system works
The system works according to the principle of reverse osmosis: tap water is forced through a special membrane with
ultra-fine pores by the pressure of the water mains supply. These pores are so small that only small water molecules
can pass through. The larger molecules of harmful substances, hardness elements and salts, on the other hand, are
filtered out. Even bacteria and viruses are removed. The result is extremely soft and highly pure water.
The standard fine filter with a pore diameter of 5 µm removes even the smallest of floating particles from the tap
water, thus preventing the osmosis membrane from becoming blocked. The active carbon filter protects the membrane
safely against aggressive chlorine.
The precision flow restrictor automatically guarantees an optimum ratio of osmosis water to residual water of 1 : 4,
thus ensuring a long membrane operating life

·
Remove the two holding clips from the membrane container and affix them vertically one above the other at a suita-
ble distance from one another on a wall or board.
Please note: Ensure that there is a suitable facility to allow the water to drain away beneath the osmosis system to
enable water to drain away without causing damage in the event of possible leakages.
·
Carefully press the osmosis system into the holding clips.
Connect the tap adapter of the osmosis system to a 3/4" tap (cold water tap!). Ensure that the seal fits properly.
·
·
Place the residual water hose and initially also the osmosis water hose in the drain. The flushing valve must be closed
(level at right angles to the flow direction).
·
Carefully open the tap, to begin with only slightly.
·
Now check all hose connections and screws carefully to ensure that they are watertight.
(In case of leakages see point 11)
·
Open tap fully. Allow the system to run for 2-3 hours in order the rinse away the preservative in the membrane. During
this period, do NOT use the osmosis water, but allow it to drain away.
·
Your DENNERLE Osmosis system is now ready for use. The osmosis Water can now be collected and used.
The residual water can also be used, for example for cleaning, watering your houseplants or flushing your toilet.
Recommendation: The osmosis water reservoir should be equipped with a safety overflow to channel the water into the
drain. This will enable you to prevent "flooding" should you forget to turn off the system in time.
4 Quality of the osmosis water
The DENNERLE osmosis system reduces harmful substances in tap water such as heavy metals, nitrate, phosphate and
pesticides as well as hardness elements and salts by at least 95 %. Osmosis water is therefore very soft and virtually
free of any harmful substances.
Total hardness and conductivity of the osmosis water depend on the tap water:
