5.2 Cleaning
Clean the reverse osmosis device only with a moist cloth and
mild detergents.
Use cloths without any fibres!
For the protection of the surface of the device,
please do not use: bleaches, solvents, alcohol.
5.4 Replacement of membrane element
In dependence of the feed water quality and the pre-treatment
salts (predominantly limescale) 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 must be performed by an
authorized service technician.
Please record in case of a membrane exchange:
✔ 1. Date of membrane exchange:
✔ 2. Permeate L/H (display):
✔ 3. Permeate (μS/cm) (display):
✔ 4. Pump pressure max. 8 bar! (display):
✔ 5. Feed water temperature (display):
✔ 6. Feed water pressure (pressure gauge external):
✔ 7.
