reverse osmosis system have been designed in such a way that they can usually be operated
with feed water quality of “drinking water” quality (according to EPA “National Primary Drinking Water
Regulation” (2009)) (
The service lifetime of the reverse osmosis membranes used and the permeate quality of the product flow
of the reverse osmosis system depend directly on the concentration of the individual water contents and
can be optimized through suitable pretreatment methods.
The critical parameters are highlighted in
part 1, chapter 2.1, in the column “Feed water for reverse
osmosis” in these operating instructions (bold print).
Ambient temperature
5–40°C / 41…104°F
Internal temperature of housing
5–70°C / 32…158°F
Relative air humidity (control)
max 75 % rel. hum., non-condensing

Stainless steel 316L, EPDM, PP, PS, PVDF, PA
Design data
NOTICE
Additional information on life expectancy of carbon filters, softener resin, pre-filtration,
reverse osmosis membranes that are relative to the user's typical feed water is available
upon request.
WARNING
Product water is proportionally related to feed water quality. Feed water must be monitored,
since changes in product water may exceed acceptable limits if feed water deteriorates
significantly, the operator is responsible for monitoring.
Raw water requirements
Water intake (raw water)
At least double the pure water capacity (when using a pretreatment
system, the minimum water consumption for this system must be added)

Temperature range
6–30°C / 42.8…86°F
NOTICE
Incoming tap water contaminants, temperature, pH, pressure and flowrates have a direct
impact on the quality and quantity of the water treatment system output.
You must be aware of changing tap water conditions. This can be easily accomplished
with good, two-way communications with your municipal drinking water supplier and with
routine testing of the tap water provided to you.
WARNING
The raw water quality must be in accordance to National Primary Drinking Water or
Standards of the United States Enviromental Protection Agency (EPA) (US). Raw water
must not contain more than 0.1 ppm Iron or 0.1 ppm Manganese.
