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.

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.

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 3 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. The status and the current
performance values can be checked via the display and pressing the corresponding buttons.
The measurement of the filter performance is set for maximum economic efficiency. If, for example, you
fail to change the RO membrane, the resin in the resin filter will require frequent replacement, increasing
your maintenance costs.
The measured values in the device are calculated for a consumption period of 12 months. As soon as the
filter performance of the membrane decreases, the resin consumption increases slowly, since higher
ppm values now arrive at the resin filter. If the exchange of the membranes is then more favorable than a
continuous change of the resin cartridge, the device recommends a membrane change.

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:
1. Connect the power cord to the power supply.
2. Turn on the main power switch
`The start screen appears.
`A sequence of images appears in the display, which
reminds you to connect the hoses and bleed the air out
of the HydroPower RO.
3. Connect the hoses.
4. Turn on the water supply and make sure that the unit
is completely filled with water. To check that, press the
yellow pressure buttons. When water comes out, the
vessels are filled.
5. Turn the on / off knob to the green position. The pump
will turn on.
6. Bleed the HydroPower RO by pressing the button on
the front two filters for a few seconds until water is
discharged.

7. The system is automatically initialized. The resin is
first by-passed. This is followed by a stabilization of the
filters, in which a status measurement is carried out,
so that all values are displayed correctly.
8. The display shows the status of the 4 filter cartridges.
It uses a traffic light system.
• Green = Everything is all right.
• Yellow = The values reach a critical range, keep a
replacement filter ready.
• Red = Caution, you should now change the filter.
• Red flashing of the selection buttons = Warning,
change this filter right now. The filter is no longer
effective and will cause the other filters to be used
excessively and the cleaning performance is no
longer guaranteed.
9. The display shows the overview of the resin filter, which
informs you about the water quality being produced by
the HydroPower RO.
`Use the buttons next to the display to switch between
the filters.
`The state is indicated by the colours on the right side of
the display.
`The colour in the display or the colour of the 4 buttons
immediately indicates whether the filter is functioning
properly or has to be replaced.
- The middle part of the display shows the TDS value
(number of dissolved solids) of the incoming water
(from the tap or from the previous filter) and the
outgoing water (after filtering).
- The lower section shows the water flow.
`In the lower section of the carbon/sediment combi pre-
filter display, the amount of water able to be filtered is
counted down until the filter has to be replaced.
10. Turn the on / off knob back to the centre position.
3The HydroPower RO is now ready for use.

Operation of the HydroPower RO
General information
www.ungerglobal.com
20
NOTE
You can adjust the amount of pure water produced by moving the on / off
knob within the blue control range.
Centre position = Recommended working position for an optimal
membrane life.
Below the centre position = less pure water is produced.
Above the centre position = more pure water is produced. The load on
membranes and resin increases, which results in higher consumption
costs.
5 Operation of the HydroPower RO
5.1 General information
