Clean the reverse osmosis device only with a ✔ moist cloth and
mild detergents.
✔ Use cloths without any fibres!
✔ Please do not use:
Bleaches,
Solvents,
Alcohol,
to protect the surface of the device.

5.3 Replacement of membrane element

In dependence of the feed water quality and the pre-treatment
salts (predominantly calcium) can be deposited on the membrane
and impair the performance (volume flow) of the membrane and
the quality of the permeate.
If the permeate volume flow declines or the conductivity in the
permeate rises, the membrane element has to be exchanged.
However, this is required latest after 12 months in any case.
➤ The exchange should be executed by the BWT service.
Please record in case of a membrane exchange:
✔ 1. Date of replacement of the new membrane element:
✔ 2. New output of the RO unit (display):
✔ 3. Water quality (μS/cm):
✔ 4. Operating pressure of the device:
✔ 5. Feed water temperature:
✔ 6. Feed water pressure:
✔ 7. Measurement of water hardness °dH (with hardness test set):
