The connections of the unit are (please refer to Fig. 1):
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).

The flow rates of permeat and waste water are:
Reverse osmosis unit
easy line 90
easy line 150
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.

Use of the water
Rejection rate:
The retention rate of the membrane is approx. 95%. Nitrate and silicate are only rejected up to
max. 70%.
The water can be used in various areas:
In salt water aquaria:
- for preparation of salt water
- for preparation of „Kalkwasser" or Calcium enriched water
- for re-filling evaporated water

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-ring (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 permeat outlet, however, at a lower flow rate.
Flow rate (litre/hour) at 4 bar and 15° C
Pure water/permeat
3.0 – 3.75 l
4.5 – 6.25 l
Waste water/concentrate
approx. 16 l
approx. 25 l
