- The module is blocked or used up:
The membrane has to be changed.
As spare parts all standard 18“- membranes with the model specific capacity can be used.
Only TFC- membranes made of Polyamide/Polysulfone should be used. We recommend to
use the original
TFC-membranes. If you want to use a membrane with a
different capacity, you have additionally to change the flushing valve.
- The
r
ejection rate is too low:
Check the water flow rates (waste water, pure water).
If the water flow is ok, flush the unit for approx. 60 min, by removing the flow restrictor. If
the rejection rate increases, go on flushing until the value is acceptable. If the rate does not
improve, change the membrane.
7. Important Notes
- Connection:
Connect the reverse osmosis unit only to the cold water supply. Higher
temperatures increase the pure water production, but at temperatures above 40°C, the
membrane will be destroyed.
- Stopping the unit:
If you stop the unit, always close the tap water supply. Put never a valve
into pure water. If you run the unit automatically with a solenoid valve, switch the valve
between prefilter and module. Take care that waste water and pure water can flow away
freely.
- Disconnection of the unit:
If you want to disconnect the unit for a period longer than 6
weeks, you should add AQUA MEDIC desinfection liquid into the module housing. If the
unit is then started again, flush it for 15 min. We recommend flushing also after shorter
periods of stopping.
- Storage:
The unit has to be stored at temperatures above 0° C. Freezing would destroy the
membrane.
- Temperature:
At low temperatures in winter, the permeate production slows down. For the
calculation of the production rate, see the following table.
8. Warranty
We guarantee 12 months on material defects. Wearing parts, e.g. prefilters as well as damages
caused by use of force and incorrect storage (freezing) or handling are not covered under
warranty.
is not liable for consequential damages (e.g. caused by water).
Warranty only by proof of purchase by the original invoice.
