System overview
4 Preparing for use
4.1 Construction of the HydroPower RO S
4.2 Interfaces
On the front is 1 connection for attaching the hose for the water fed
pole and 1 connection for the water supply. These are standard hose
connections.
Make sure that water cannot flow back into the tap water line, e.g.
through a backflow prevention device.
The water outlet for the concentrate is located at the back. Pour the
concentrate down the drain unsing the enclosed concentrate hose.

8 Carbon/sediment combi pre-filter
9 Membrane
10 DI resin filter
11 Pump ventilation slot
12 Pump Control
13 Power cord
14 Concentrate output
(connection concentrate hose)
The manometer shows the water pressure behind the pump. Ensure that
the water inlet pressure is at least 1 bar. The optimum is 4 bar, maximum
should not exceed 6 bar. The pump increases the pressure by approx. 4 bar.
Accordingly, the pressure in operation should not exceed 10 bar.
ENGLISH
The TDS meter shows the water quality at water outlet for the Pure and the
Boost Mode.
PURE: TDS metre shows the value of the filtered water after RO Membrane
and DI resin. It should ideally show a value of 0. At the latest when it shows
10, the resin should be replaced.
TAP BOOST: TDS metre shows the value of the tap water.
The water meter measures the water flow at the inlet. This is particularly
important for the combination pre-filter, as it must be replaced after approx.
30,000l.

Transport and storage
4.3 Transport and storage
4.3.1 Transport
The HydroPower RO S is delivered on a pallet by a forwarding company.
The HydroPower RO S is carefully tested and packaged before shipment. However, damage during
transport cannot be ruled out.
Therefore, immediately check the HydroPower RO S for integrity in the presence of the dealer.
Check the completeness of the delivery, see chapter „2.3 Scope of delivery“.
Carry out a visual inspection of the HydroPower RO S for transport damage.
If the HydroPower RO S has been damaged during transport, show the damage to the company delivering
HydroPower RO S on behalf of your dealer.
Complaints due to transport damage cannot be accepted without written confirmation by the dealer or
with unreserved acceptance!
In the case of transport of the HydroPower RO S for use at height, e.g. on a house roof:
DANGER
Severe injuries and property damage due to the HydroPower RO S
falling are possible.
`Do not walk or grab under the suspended load.
`Use only the fixing points provided for fixing the hoist.
`Only use a suitable hoist.
`Secure the HydroPower RO S to the transport.
`Observe the weight and maximum dimensions of the HydroPower RO S.
`Wear protective gloves and safety shoes.
When transporting, ensure that the HydroPower RO S is
properly secured and cannot move in the transport. Protect
the HydroPower RO S from external damage.
Use the fixing points of the frame during transport, or if the
HydroPower RO S is lifted with a crane, in order to avoid
damage.

Operating the HydroPower RO
4.3.2 Storage
If the unit is not in use for more than 7 days, the membranes must be protected according to the storage
instructions, see chapter „7.2.4 Membrane protection“.
4.3.3 Operating the HydroPower RO
What is Pure Water?
Pure Water is water in its purest form, physically processed to remove the minerals that
would otherwise lead to limescale spots and streaks. Such impurities are referred to as TDS
(Total Dissolved Solids) and are measured in ppm (parts per million). The water is considered
100 % demineralised (pure) when its TDS is measured at 0 ppm, whilst the 180 ppm is
considered as average water hardness.
Flow of water purification
The water enters the HydroPower RO S via the water inlet (1).
The carbon/sediment combi pre-filter (2), which filters out the largest impurities and chlorine from the
water and thus protects the membranes, sits before the membrane.
The membrane filter (3) removes up to 98% of the minerals from the water in the HydroPower RO S.
The resin filter (4) sits after the membrane, which removes the last 2% of the minerals from the water in
the HydroPower RO S.
Pure water is discharged from the water outlet (5) into a hose connected to a water fed pole for cleaning
glass surfaces without chemicals.
The 3 filter cartridges (2-4) can be easily removed and replaced (see page 27).

4.4 Commissioning
CAUTION
Slight injuries due to pressurized containers possible.
`The 3 filter cartridges are pressurized during operation.
`Never remove a filter vessel during operation.
`Check if the hoses and tubes are water-tight and fit properly before
commissioning the system.
`Use protective gloves.
ATTENTION: For new or conserved units, the resin filter is removed from the unit and must be
inserted! See next page.
To start the HydroPower RO S, proceed as follows:
1. Connect the two hoses. Do not forget the concentrate hose at the
back of the unit.
2. Connect the power cord to the power supply.
3. Turn on the water supply
4. Put upper switch to the position „WORK“
5. Turn the lower switch from OFF > PURE to work with pure water.
6. The pre-filter cartridges must fill completely with water before
100% efficiency can be achieved.
`
The red RESTART button on the pump control on the back restarts
the pump in case of low pressure. As the system is only just filling
with water at this point, press the RESTART button until the filling
process for both filter cups is complete.
The excess air escapes through the water and concentrate outlets.
3The HydroPower RO S is now ready for use.
`
Info: When you select „TAP BOOST“, unfiltered tap water with
increased pressure comes out to flush surfaces and remove stuborn
dirt.

Commissioning
4.4.1 Commissioning of new or preserved HydroPower RO S:
The pre-filter and the resin filter are not inserted in new or preserved units, as they must not come
into contact with the diaphragm care agent.
Before using the resin filter, the membrane maintenance agent must be completely rinsed out.
1. Open the water line and start the HydroPower RO S by setting the upper
switch to „RO FLUSH“ and the lower switch to „PURE“. Rinse out the
membrane care agent for about 15 minutes.
2. Switch off the HydroPower RO S: turn the lower switch to OFF.
3. Disconnect the water supply.
4. Unscrew the resin cartridge and insert the resin filter (RORE2).
Make sure that the orientation is correct, the blue filter inlet must be on
top!
5. Screw the cartridge back on with help of the included filter key.
6. Start the HydroPower RO S by setting upper switch to WORK and lower
switch to PURE.
