Membrane protection
The membrane achieves its optimal life with regular water flow or flushing.
If the HydroPower RO is not in use for an extended period of time (longer than 7 days), the membrane
must be protected against blockage.
For this purpose, there is the UNGER Membrane Care Agent (Order No. 15436). You need one bottle (1l) for
each membrane. This preserves the current state of the membrane and prevents reduced performance
and/or damage after sitting for a longer period of time. Alternatively, you can run the unit once a week for
approx. 30 minutes to rinse the membranes.
To protect the membrane, proceed as follows:
1. Switch off the HydroPower RO and disconnect the
power supply.
2. Drain the water from the HydroPower RO.
Unscrew all filter top caps and open the pressure relief
valve on the back of the HydroPower RO until no more
water leaks out.
3. Close the pressure relief valve and screw the yellow
cap onto the concentrate outlet.
4. Remove the pre-filter and resin filter cartridges and
store them protected from dust and dirt.
5. Pour one bottle of membrane care liquid (1l) into each
of the mebrane tanks.
6. Fill all tanks (#1 pre-filter + both membranes #2, #3)
with tap water until all three tanks have filled just
below the top edge. Tank #4 can remain without water.
7. Close all four tanks.
The membranes are protected and the HydroPower RO
3
can be stored.
