Aqua Medic easy line 90 Manual De Instrucciones página 11

In fresh water aquaria:
- pure for breeding soft water fish
- hardened up with Hydrocarbonate in all fresh water tanks
- pure for re-filling evaporated water
In households:
- for preparation of food and drinks
- for car batteries and flat irons
- for home plants, especially orchids, bromelids and cacti
In laboratories and industry:
- everywhere, where up to now distilled or deionized water has been used and a conductivity of
>20 µS is accepted.
5. Maintenance
- Rinsing: For rinsing the membrane, the flush valve (Fig. 1, No. 11) has to be opened.
Afterwards, the water flows at full speed through the reverse osmosis module and flushes
most contamination and residues.
This should be done after each production of osmosis water for 5 minutes (dependent on
-
contamination and produced quantity of osmosis water). Afterwards, the flush valve can be re-
mounted and the unit is ready for next production. By rinsing the membrane, possible deposits
in the membrane are avoided and thus, the life span of the membrane is extended.
- Pre-filter: If the tap water is not extremely polluted, a yearly replacement of both pre-filters
will be sufficient. If the water is higher polluted, the filters have to be changed more often - as
required. If the pre-filter is blocked, the water production will slow down. On changing the
pre-filter, always rinse it before mounting it to the osmosis module.
Membrane: The membrane normally has a lifetime of several years. Afterwards, it has to be
-
replaced.
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 membrane 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.
