General safety regulations
3 Safety
3.1 General safety regulations
3.1.1 Basic principles
Special safety regulations may apply to certain activities. Safety instructions and warnings are given in the
respective sections of the operating instructions.
Operate the HydroPower RO only:
• in accordance with the operating instructions for safety and driving safety
• if the HydroPower RO is in a technically sound condition.
This includes:
• The safety stickers attached to the HydroPower RO must always be complete and in good readable
condition. Renew damaged or unreadable signs.
• Carry out cleaning and maintenance work on the HydroPower RO only if it is disconnected from
electricity.
Turn off the main power switch and unplug the power cord.
• Carry out maintenance on the filter vessels only if they are depressurized.
• Clean the HydroPower RO after use of dirt and impurities.
Use personal protective equipment to avoid personal injury:
`protective gloves,
`safety shoes,
`safety goggles.
3.1.2 Unit protection and warning processes
Overheat protection
If the pump overheats, the overheat protection is triggered automatically and the HydroPower RO switches
off.
Pressure relief valve
If the water pressure in the HydroPower RO is too high (above 10.5 bar), the pressure relief valve opens
at the back of the HydroPower RO and releases excess water through the concentrate hose to reduce the
pressure in the system.

System overview
4 Preparing for use
4.1 Construction of the HydroPower RO
4.2 Interfaces
On the front are 3 connections for attaching hoses for water fed
poles 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 using the enclosed concentrate hose.

11 Main switch (On / Off)
12 Pump Reset
13 Pump ventilation slot
14 Power cord
15 Concentrate output
16 Pressure valve
(with lever for manual draining of water)
The manometer shows the water pressure on the membranes when the pump
is running. Ensure that the water 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.
At a pressure of 10.5 bar, the pressure relief valve opens automatically at the
rear.
ENGLISH
The TDS meter shows the water quality behind the RO membranes and
behind the DI resin filter. The membranes (RO) should operate at 95-98%
efficiency in relation to tap water.
The resin filter (DI) should ideally show a value of 0. At the latest when it
shows 10, it should be replaced.

Transport and storage
4.3 Transport and storage
4.3.1 Transport
The HydroPower RO is delivered on a pallet by a forwarding company.
The HydroPower RO is carefully tested and packaged before shipment. However, damage during transport
cannot be ruled out.
Therefore, immediately check the HydroPower RO 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 for transport damage.
If the HydroPower RO has been damaged during transport, show the damage to the company delivering
HydroPower RO 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 for use at height, e.g. on a house roof:
DANGER
Severe injuries and property damage due to the HydroPower RO 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 to the transport.
`Observe the weight and maximum dimensions of the HydroPower RO.
`Wear protective gloves and safety shoes.
When transporting, ensure that the HydroPower RO is
properly secured and cannot move in the transport. Protect
the HydroPower RO from external damage.
Use the fixing points of the frame during transport, or if
the HydroPower RO 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 via the water inlet (item 5).
The carbon/sediment combi pre-filter (item 1), which filters out the largest impurities and chlorine from
the water and thus protects the membranes, sits before the membranes.
The 2 membrane filters (items 2, 3) remove up to 98% of the minerals from the water in the
HydroPower RO.
The resin filter (item 4) sits after the membranes, which removes the last 2% of the minerals from the
water in the HydroPower RO.
Pure water is discharged from the 2 water outlets (item 5) into a hose connected to a water fed pole for
cleaning glass surfaces without chemicals.
The 4 filter cartridges (items 1 - 4) can be easily removed and replaced.

4.4 Commissioning
CAUTION
Slight injuries due to pressurized containers possible.
`The 4 filter vessels are pressurized during operation.
`Never open a filter vessel during operation.
`Check if the hoses and tubes are water-tight and fit properly before
commissioning the system.
`Use protective gloves.
To start the HydroPower RO, proceed as follows:
ATTENTION: For new or conserved units, the resin filter is removed from the unit and must be
inserted in step 14 !
1. Connect the hoses. Do not forget the concentrate hose at the back
of the RO35C.
2. Turn on the water supply
3. Connect the power cord to the power supply.
4. Turn on the main switch.
5. Wait until the system is completely filled with water. You can check
this by pressing the two yellow buttons on the front filters. As soon
as water comes out here, the tanks are filled.
6. Turn the yellow rotary switch to the upper position. The filtered pure
water is delivered to the two water outlets.
3The HydroPower RO is now ready for use.

HydroPower® RO35C
Commissioning
4.4.1. Commissioning of new or preserved RO35C:
The resin filter is not used in new or preserved units, as it 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. Start the appliance as described on page 18 and let it rinse out the
membrane care agent for about 20 minutes.
2. Switch off the RO35C: turn the yellow switch to RO FLUSH.
3. Then turn off the main switch.
4. Disconnect the water supply.
5. Insert the resin cartridge. Make sure that the orientation is correct, the
arrow on the cartridge must point downwards, or the blue paper filter
must point upwards!
6. Press the resin cartridge a little firmly so that it sits well on the rubber
seal.
7. Screw the cover back on.
8. Start the RO35C with steps 1-6 on page 18.
3The HydroPower RO is now ready for use.
NOTE
You can adjust the amount of pure water produced by moving the yellow control
knob between the left and upper position.
Middle position = Recommended working position, for optimum membrane life.
Below the middle position = Less pure water is produced.
Above the middle position = More pure water is produced. The load on
membranes and resin increases more, which results in higher consumption
costs.
