1. Product description
The AB Aqua Medic
reverse osmosis unit Premium Line 90/150
is a compact and highly
efficient unit with a daily capacity of 75 - 90 / 120 - 150 litres. It consists of the following parts:
- Sediment prefilter,
10“ with
5 µm pore size (6/10)
- activated carbon filter (7/11)
- 1 reverse osmosis module with a first class synthetic membrane (Polyamide/Polysulfon, TFC)
which has a capacity of 75 - 90 / 120 - 150 litres (5)
- flushing valve: at this valve (3), the permeat/concentrate ratio is adjusted to 1:2,5 - 1:3
- tap water connection fitting (3/4“)
with
3 m pressure tube
2. Set-Up
The system is delivered ready-to-use on a mounting unit. Fix it directly on the wall - preferably
near a water tap.
Then, remove plugs from the fittings and connect the tubes. To avoid any failures, follow the
instructions carefully:
Tube Fittings:
- First of all, remove the plugs.
- Put the nut and the small ring on the tube (flushing valve).
- Push the tube tight into the fitting and fix the nut.
The connections of the unit are (see Fig. 1):
1. Tap water inlet - into the sediment pre-filter (1)
2. Concentrate outlet (waste water) at flushing valve (3)
3. Pure water (permeat) (2)
4.Tap water connection
Fix the water connection piece to a 3/4“ water tap (cold water). If it does not fit, use a reduction
piece (not included in shipment).
3. Starting
When all connections are tight, you can open the water tap. The minimum water pressure for the
unit is 3 bar. The nominal capacity is reached at 4 bar. If the pressure drops below 3 bar, the
production capacity is reduced, below 2 bar it reduces also the reduction rates.
First of all, check all connections on water tightness. If leakage occurs, tighten the fittings or the
housing.
Now, the concentrate flows out of the outlet (3). After some minutes, also the purified water flows
out of the permeat outlet (11), however, at a lower flow rate. The flow rate of pure water is
approx. 2.5 – 4 / 4 – 6 l/h, the flow rate of waste water is approx. 12 - 15 / 15 – 18 l/h (at 4 bar
and 15 °C). Lower pressure or temperatures reduce the pure water capacity.
The pure water produced within the first 2 hours has to be discarded, because it may contain
residues of disinfection liquid which has been filled in the module for storage. After 2 hours of
operation, the water can be used.
