Note: Before taking the unit into first operation, rinse the pre-filter and then attach it to the reverse
osmosis module!
1. Attach the tap connection to a 3/4" tap. If necessary, use a reduction piece (not included in shipment).
2. By using a piece of tube, one puts it from the tap connection into the tap water inlet of the unit into the pre-
filter (1).
3. Connection between pre-filter and reverse osmosis module.
4. Waste water outlet (6) at the flush valve.
5. Pure water (permeat) (5).
Mounting the membrane:
Remove the screw cap of the module housing (Fig. 1, No. 4). Take the membrane out of the plastic bag and put
it into the reverse osmosis module. Take care to insert the membrane in the right direction (Fig. 2, No. 2) with
both sealings (Fig. 2, No. 1) directed to water outlet. The membrane has to be pushed forward until the 2
sealings are in the right position at the top and the pure water sealing (Fig. 2, No. 3) is fixed. Before the
housing can be closed, mount the O-rings (Fig. 1, No. 9) on the reverse osmosis module.

Starting:
When all connections are tight, you can open the tap water. The minimum water pressure for the unit is 3 bar.
The nominal capacity is reached at 4 bar. If the pressure drops below 3 bar, the production capacity is reduced,
below 2 bar it also reduces the rejection rate.
Firstly, check all connections on water tightness. If leakage occurs, tighten the fittings or the housing. Now, the
concentrate flows out of the outlet at closed flush valve. After some minutes, also purified water flows out of the
permeate outlet, however, at a lower flow rate.
The pure water, produced in the first 2 hours, has to be discarded because it may contain residues
of the disinfection liquid which has been filled in the module for storage. After 2 hours, the water
can be used.
3. Use of the water
Rejection rate:
The retention rate of the membrane is up to 98%. Nitrate and silicate are only rejected up to max. 70%.
The water can be used in various areas:
In saltwater aquaria:
-
for preparation of salt water
-
for preparation of „Kalkwasser" or Calcium enriched water
-
for re-filling evaporated water
In freshwater aquaria:
-
pure for breeding soft water fish
-
hardened up with Hydrocarbonate in all fresh water tanks
-
pure for re-filling evaporated water
