Introduction
INTRODUCTION
© COPYRIGHT UNGER GMBH
When choosing the Unger HydroPower RO XXL pure water filter system, you have decided in favour of a high quality
product.
In this system two desalination filters are working. The minerals responsible for producing hardness and the
conductivity (TDS value) are removed from the water. First the main quantity of minerals is filtered out by a reverse
osmosis membrane (RO). After that a deionisation filter (DI) filters the rest to achieve a 100% pure water result.
Complete desalination is based on the principle of reverse osmosis, supported by ion exchange in this system.
The application of this treatment has the following advantages:
• A water fed pole and a brush are all that is needed for glass cleaning.
• Prior to system installation and start-up it is essential that you observe the safety
regulations & instructions for installation and maintenance contained in these instructions.
• The manufacturer is not liable for the function of the device:

General Warnings
1. SAFETY  GENERAL WARNINGS
General:
Please observe the applicable rules and regulations, as well as the effective accident prevention regulations.
UNGER is not liable for any occurring water damage. Make sure that the area of application has sufficient water
drainage. Close feed valve in case of prolonged shut-down times (e.g. weekends).
The HydroPower RO XXL can be exclusively used by trained and qualified persons who have been instructed in
the service of it and explicitly with the service of it have been charged.
For this reason a complete knowledge of this guide is necessary to avoid damage to yourself, third parties,
objects or to the machine self. The HydroPower RO XXL is not suitable for use by children or young people! Not
instructed personnel or persons with limited psychical, physical skills may not use the machine.
If the machine is used by other persons than you must as an owner inform the user of the safety regulations. The
use of the HydroPower RO XXL falls under the applying national provisions. Beside the instructions for use and
in the country where the machine is used applying binding regulations concerning accidents prevention, also the
recognised technical rules for safely and judicious work must be observed.
Each working method which can be dangerous for safety matters must be avoided.
Protect the trailer from standing in direct sunlight. The black cover and the metal plates become hot and could
lead to injuries. The longevity of all components like membrane, resin filter and even pure water is longer at
normal temperatures.
Hoses:
Hoses, fittings and joints are important for the safety of the machine.
Use only by the manufacturer approved parts! Do not use the hose as a draft cable.
Look out for tripping hazard when the hose is unrolled from the reel.
Please note: block the hose reel with the locking handle and hook, couple the left/right flow reel hoses to the
RO- connections at transporting the trailer (so the hoses are locked & could not unroll!)
Uncouple the hoses again (after transport) from the RO- connections when using the reels of the cleaner!
Spraying:
The water hose may not be aimed on yourself, persons, animals, installations under electric tension or at the
machine itself.
Never spray electric installations with water: danger for persons, short circuit danger.
Carry safety clothing, safety optical device, if necessary!
During the use keep all protective coverings and doors (cap) of the machine closed!
Any surface that becomes wet must be identified with appropriate signage to direct pedestrians and workers
away from work area. During wintertime, it is important to avoid water pooling, which could freeze, creating a
dangerous slip hazard. Do not clean sensitive parts with the jet.
Never spray water from an unstable duty station/place (ladder, small boat, wharf...).
Spray equipment:
Stop the machine, if spraying equipment need to be exchanged. Fix the spray equipment correctly.
Take the necessary safety precautions when spraying!
Machine:
Never take the HydroPower RO XXL in use without water. Even a brief lack of water can lead to
damages! When the machine is connected to the drinking water supply, the existing regulations about that must
be observed (EN 1717). The machine must stand on a stable horizontal base & with the trailer in braked position!
Working at artificial light: if daylight offers not sufficient visibility during the use, the use of adapted
impermeable lighting armature(s) stretches to recommendation. In spaces provide with standard lighting these
must remain on wide distance of the water jet. Never work outdoors during a storm or bad weather.
Fixed adjustments of the machine may not be modified under no circumstances.
The nLite® HydroPower RO XXL has been made in running order and tested by UNGER according the safety
standards. When the machine is in use these can never be left behind unattended.
Do not spray materials containing asbestos or other health-hazardous substances.
Water outlet:
Take care for a sound and smooth water outlet of the concentrate.
Traffic:
Protect piping and cables with protective boards/plates when they are lying on a roadway.

General Warnings
1. SAFETY  GENERAL WARNINGS
DI Ion exchange resin filter:
Transportation: ensure that the DI tank is properly secured to the related moulding in the trailer.
This device may cause danger if it is improperly installed, not regularly maintained or not used as intended.
Use this device only for water treatment to reach an optimal water quality for glass cleaning. Any other use,
especially water treatment for food production (e.g. beverages) is considered as non- intended and not allowed.
When operating with water other than from drinking water system, e.g. from a well, a water analysis must be
performed prior to application to determine if the water is suitable.
Excess impurities in the water may have an adverse effect on system performance and cleaning result.
Resin can cause skin irritation. Avoid skin contact.
If you use loose resin: Pay attention to not overfill the vessel. Only use new, saturated wet resin. Never use dry
resin as this will expand a lot and can destroy the system.
Possible failures at spraying activities:
• Trip hazard to the general public when using trailing hoses.
• Slip hazard presented from wet pathways.
• Slip hazard for operator when concentrating on work.
• Falls from height when working on flat roofs.
• Electrocution from poles coming into contact with overhead power source.
• Injuries to others from falling poles or fabric of the building that may be dislodged.
• Injury to others from falling poles caused by incorrect handling or failure of pole.
• Injury through incorrect manual handling of poles and other equipment.
• Spread of legionella disease through poor maintenance of system.
• Hazards from carrying tanks, systems and equipment that are overloaded, unstable, unsecured or incorrectly
installed within a vehicle.
Personal safety measurements:
Do not drink the water produced by this system.
Water produced by the machine is too pure and will rob the body of vital minerals and nutrients if imbibed in
quantity.
When operating with a tap waterline, it must be assured that the connected water hose is equipped with a non-
return valve to prevent water flowing back into drink water line!
Trailer:
We recommend to transport the trailer without water, a filled water tank could affect the riding behavior of the
trailer. Do not climb on the trailer if it is not connected to a towing vehicle. No permitted use as a lifting device
for either people or animals! None of the safety devices may be removed or put out of operation.
Ensure that nobody can become trapped, do not exceed the maximum load/maximum permitted ball thrust (see
type plate). A valid driving licence is obviously required for driving with the trailer.
Your trailer should ALWAYS be provided with good readable, official license plate according to your country
regulations. Place the plate on the back side of the trailer and make sure it is properly illuminated by the license
plate light! Also note on a good tire pressure!
Pay attention to the risk that the trailer might skid or swerve, you should also adjust your driving speed
depending on road conditions and the load you are pulling.
This applies especially to bends, notice that your car reacts differently with the trailer coupled! In runs with a
brake, trailer loaded, it is important that you limit the speed for handling and manageability of your combination.
Do not handle this speed limit as striving but as absolute maximum!
Hand brake:
Pay attention to risk of accident due to failure of the hand brake! If the trailer is to be uncoupled from the
towing vehicle, the hand brake must be applied and the trailer must be secured by means of two additional
wheel blocks. At parking or placing of the whole combination, tighten also the hand brake!
Danger - risk of injury! The trailer may roll back before the full braking force is applied!
Ensure that there is sufficient space when parking the trailer.
Breakaway cable:
Always route the breakaway cable through the breakaway cable guide ring!
See photo beneath.
Attach the breakaway cable in such a way that cornering is not impeded.
The breakaway cable must not be wrapped around the jockey wheel.
Observe country specific regulations when attaching the breakaway cable.
Danger due to uncoupling of the trailer!
Jockey wheel/ support arm: Ensure that the jockey wheel is seated securely
and that the support arm is secured, before driving on the road!

Before use
2. BEFORE USE
For each start up all substantial parts of the HydroPower RO XXL must be checked by taking them in
consideration like for example: all the cleaning equipment is still fixed firmly, check hoses and electric wiring on
damages. Persuade yourself of the safety regulations from previous chapter.
Before starting, check the HydroPower DI on cracks. Be sure the cover is in locked position.
Keep discharge line open and hold yellow lever down to remove trapped air from system.
For use only with drinking water.
2.1. Accomplish water supply and water outlet
2.1.1. Accomplish water supply
The water supply pipe can be connected (towards circumstances) on their own water supplies
(under pressure) or on a drinking water supply with a water barge. When the machine is connected to the
drinking water supply, the existing regulations about that must be observed ( EN 1717 ).
Water supply under pressure:
Maximum hose length 50 m (160 ft), minimum hose diameter (inside) 12.7 mm (1/2”).
Check the water pressure using a water meter.
2.1.2. Concentrate water
Check that all water outlets have been correctly connected.
Take the necessary measurements so that the water concentrate is suitable enough to drain.
2.1.3. Anti- legionella bacterium measure
If the machine has stood still some time, the water in the machine must be drained above an evacuation.
Stationary water that becomes hot (between 20 - 55°C) can cause the legionella bacterium.
• Clean therefore piping and tanks on a yearly base.
• Remove possible sediment.
• Rinse periodically.

3.3. Component review
Battery
The type of battery is a sealed gel block battery with specs: 12V - 210Ah.
Pressure gauge
On the manometer you can read the pressure of the incoming water, before the RO-system.
The pressure must be below 5 Bar at all times (optimal value: 3,0-3,5 bar)!
Trailer
The complete water filter systems ands the water tank are build on a trailer.
Water tank
The water tank provides a buffer of pure water and prevents that there may appear pressure impulses
in the water system. The water tank has a volume of approx 750 Litres. Below the water tank there’s
a drain valve provided to drain the water from the tank (see picture A). At the back side of the trailer
there’s a cap which can only be used to check the water level of the water tank or for any maintenance
activities in the tank (see picture B).
Note: the cap on the water tank can NOT be used to fill the tank. Filling through the cap may in no
case be done, the supplied water will not pass through the RO & DI and so it is no pure water.
Unger is not responsible for possible damage caused by improper use of the cap.
Please also add no other products (such as chemical products, ...) in the water tank through the cap!
Water Pre-filter
The water supply will be filtered with the carbon water filter and ensures the durability of the osmosis
membrane.
Osmosis system
Reverse Osmosis is a separation process in which feed water
permeates a selective membrane. Dissolved as well as undissolved
materials are rejected by the membrane and carried away in the
concentrate water stream. The purified water contains only a fraction
of these materials, with TDS - total dissolved solids (a measure of the
salt content in water) of the original feed water concentration.
Ion exchange resin filter
The ion exchange resin filter is usually a stand alone solution to purify water. In the HydroPower RO XXL
it works behind the RO-membrane as a polisher to filter out the final minerals out of the water and to deliver
100% pure water (0 ppm).
Hose reels
The HydroPower RO XXL is standard equipped with 2 reels with each 100m.
Always secure/block the reel(s) after use and before transporting the trailer.
Disconnecting the reel coupling: pull the plastic coupling to loosen from the RO- connection, unroll the hose reel
loosening the reel lever (see photo).
Connecting the reel coupling: couple the flow reel hose coupling(s) to the RO- connection by clicking/pushing the
plastic coupling to the connection.
Secure the hose also by the reel lever so the hoses are locked & could not unroll!
Note: uncouple the hoses again (after transport) from the RO- connections when using the reels of the
HydroPower RO XXL!
The green bumpers protect the connectors when the hose is rolled back.
COUPLINGS HOSE REEL
CONCENTRATE
Containing salts are rejected by the
membrane and do not enter the product
tube. The concentrate water exits on the
side of the element opposite to the feed.
PRODUCT TUBE
Here the filtered water
flows into the tank.
TAB WATER FEED
enters into membrane layers.
Applied pressure forces raw
water across the membrane
into the product tube.
PURE WATER
collects in the product tube and
can be output from either end
of the membrane element.
