14.1 Maintenance intervals
Consumable materials are to be replaced at the intervals given in the following Table or when
there is a drop in performance:
Material Flow chart no. Article no. Interval*
Pretreatment 09.4001
Prefilter/Hardness stabilization F1
06.5204
6 Months
Pretreatment 09.4000
Prefilter
Hardness stabilization F1
06.5201
06.5452
6 Months
6 Months
Filter cartridge F3 09.4011/09.4012 12 Months
*Please keep in mind that the life of your consumables is directly dependent on the quality of
the feed water and the amount of water used daily. The interval is contingent on the feedwater
quality so that a shorter one may be necessary.
14.2 Rinsing the membrane
Rinsing out preserving liquid:
According to the mode of delivery of the system, it may be supplied filled with a solution
containing a preservative.
Should this be the case, when the system is first put into operation, the permeate obtained after
switching to production must be discarded for at least 3 – 4 hours.
To do this, each time the tank is full, open the valve at your drawing-off point and lead the
purified water to drain.
Cleaning the membrane:
The automatic flushing lengthens the service life of your reverse osmosis module by sweeping
coarse particles and other contaminants away from the surface of the reverse osmosis
membrane. The flushing phases so ensure maximum service life and optimal purified water
quality.
Leave your pure water system on over the weekend and during
holiday times. Only then can the 12-hourly rinse operate and ensure
that your reverse osmosis module is not subject to bacterial growth
during standstill periods
Should there be a reduction in the flow rate because inappropriate pretreatment has caused
blockage of the reverse osmosis module, it is often possible to recondition the module.
Such reconditioning of the module is only to be carried out by authorized service personnel
responsible for your area, or is to be returned to the manufacturer of the reverse osmosis
module. The module must be not be subjected to frost during transport.
