the appropriate wrench, remove the cartridge and refill it. Then close the 10" housing firmly and
restart the system.

Maintenance
- Flushing:
The membrane will be flushed automatically at
regular intervals. The LED Flush will
be lit then.
-
Prefilter:
If the tap water is not extremely polluted, a yearly replacement of both prefilter
cartridges will be sufficient. If the water is higher polluted, the cartridges have to be changed
more often - as required.
-
Membrane:
The membrane normally has a lifetime of several years. Afterwards, it has to be
replaced.
-
Flushing valve:
The flushing valve has a limited lifetime. In case of a decrease in adjusted
waste water flow, the valve is encrusted with calcium and can be cleaned using acid (e. g.
vinegar). If the waste water flow increases, the valve has to be replaced.
5.
Failures
- Waste water flow rate is too high:
Replace flush valve or check membrane’s power. The unit
can calcify very quickly at high degrees of water hardness. Then, the unit has to be returned for
checking to the manufacturer or dealer.
-
Waste water flow rate is too low:
Check if the prefilters are blocked. If so, replace them.
- Pure water flow is too low:
Check if the waste water flow is also low and maybe change the
prefilter.
- Tap water pressure is too low:
Check the high pressure pump.
- The membrane is blocked or expired:
The membrane has to be replaced. As spare parts all
standard 18“- membranes with a daily output of 400 litres 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 if the sealings at the connection of the membrane are tight
or if there’s a crack in the support of the membrane’s housing. If so, replace the membrane.
6. 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 and pull the power
plug.
- Disconnection of the unit:
If you want to disconnect the unit for a longer period than 6
weeks, you should take the membrane out and put it in the fridge (keep it humid) or fill the unit
with an adequate disinfectant liquid. If the unit is started again, it has to run for a few hours.
The water produced then has to be discarded.
