6. Failures
- Waste water or pure water flow rate is too low:
Check the pre-filter for blocking. Connect water inflow directly to the module. If the waste
water flow is normal again, change the pre-filter. If the flow is still too low, the flush valve or
membrane is blocked or has to be renewed.
- Tap water pressure is too low:
If you are connected to a municipal water supply, you are not able to influence the water
pressure. For the reverse osmosis unit, a minimum water pressure of 3 bar is required.
- 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
original Aqua Medic TFC-membranes. If you want to use a membrane with a different capacity,
you also have to change the flush valve.
- Rejection rate is too low:
Check water flow rates (waste water, pure water). Maybe the pre-filter has to be changed.
If the water flow is ok, flush the unit for approx. 60 minutes by opening the flush valve. 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 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. Never put a valve
into pure water. If you run the unit automatically with a solenoid valve, switch the valve
between pre-filter 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 longer period than 6
weeks, you should add Aqua Medic disinfection liquid into the module housing. If the unit is
started again, flush it for 15 – 20 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 permeat production slows down.
