Introduction
1. Introduction
When choosing UNGER complete desalination as water treatment system, you have
decided in favour of a high-quality product.
Complete desalination is based on the principle of ion exchange. The minerals
responsible for producing hardness and the conductivity (TDS value) are removed from the
water.
The application of this treatment filter 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 and instructions for installation and maintenance contained in these
instructions.
• The manufacturer is not liable for the malfunction of the device:
• When handling is not in compliance with regular use.
• When used for applications not mentioned in the manual (use other than intended),
• When failing to comply with safety regulations.
There is a risk of damage to the treatment filter if:
• Operating and installation errors.
• Usage of loose resin (Overfill, expansion of resin, resin flows into waterline)
• Vessel is opened incorrectly.
• Replacing spare parts that are not included in the official UNGER spare parts pricelist.
• Performing unauthorised modifications to the design.
• Non-compliance with safety regulations (e.g. anti-freeze protection).
• Use of chemical additives.
• Insufficient maintenance.

Saftey regulations
2.5 Attention (General hazards)
Purified water is delivered to the waterfed pole by flexible hose from the
HydroPower®Ultra system. This introduces a risk of tripping both to worker and
general public. Identify work area with appropriate signage.
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.
General hazards associated with the use of water fed poles and deionization equipment1:
• 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.

HydroPower® Ultra
System Overview
4. System Overview
4.1 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 consi-
dered 100% demineralised (pure) when its TDS is measured at 0 ppm, whilst the 180 ppm is
considered as average water hardness.
The HydroPower®Ultra offers you a bundle of great benefits, delivered through innovative
features plus 30% more resin efficiency compared to other systems.

5. Installation and start-up
5.1 New Machine Set-Up
• Unpack unit: Inspect HydroPower®Ultra system and all components. Read warnings
and operating manual.
• Inspection & Scope of Delivery: Refer to illustration; perform visual inspection and
take inventory of the following items that should be shipped with the system, then test
system for functionality:
• TDS Meter functional (powers on/off)
• Fast Lock lever (yellow) – depress lever, rotate in clockwise direction and remove
top cap assembly.
• Ultra Resin Packs installed in unit.
• DIUH1 - One green Ultra Resin Pack
• DIUH2 - One green two red Ultra Resin Packs
• DIUH3 - One green two red Ultra Resin Packs,
Trolley, wheels and tank clamp system.
• Water supply connection
• The inflowing water must comply with the applicable local Drinking Water
Ordinance.
• It must be assured that the connected watertap is equipped with a rebound valve
to prevent water flowing back into drink water line.
• Inflowing water temperature max. 30°C
• Temperature on site 5° to 40°C; not in immediate vicinity of heater.
• Do not operate in the immediate vicinity of heat sources or in direct sun.
• Depending on the composition of the raw water, the treated water is more or less
aggressive. Thus, the parts getting in contact with the treated water must be
made of suitable material (e.g. glass, plastic or aluminium). Copper and other
non-ferrous metals are not suitable.
5.2 Start-up
1. Locate jobsite drinking water supply.
2. Before window cleaning can begin, the system must be connected to a drinking water
supply (see page 7 (1). If well water system is source, it is recommended water quality
analysis be performed prior to application.
3. UNGER recommends testing the onsite water supply for TDS (total dissolved solids) (5)
prior to working. Higher TDS levels reduce the DI system‘s capacity. Conversely, lower
TDS levels will increase the amount of water the system is able to produce.
4. Inspect system – ensure UNGER’S Ultra Resin Packs (7) are properly
installed: the red coded units must always be at center and bottom position and the
green unit on top. In DIUH1 only use the green Ultra Resin Pack.

HydroPower® Ultra
Installation & Start-up
a. NOTE: The performance of HydroPower®Ultra is optimized for the usage with
Ultra Resin Packs. Never use with loose resin as then the tightness of the unit is not
guaranteed.
5. Set up system in upright position. Choose a stable onsite location;
best to locate near work area.
6. Connect hoses to system (tap water (1) and waterfed pole tubing (2),
(fig. A).
7. Ensure all waterfed pole on/off valves are in “OPEN” position.
8. Turn on tap water supply slowly.
9. Inspect system as it pressurizes and begins producing pure water.
Keep discharge line open and hold down yellow lever (3) to remove
trapped air from system (fig. B). Use only with drinking water.
10. Turn on TDS meter (5) and inspect pure water quality (fig. C).
For first time use, the TDS meter should read 000.
Stop use when TDS meter reads 010 ppm and change resin.
Adjust flow at waterfed pole brush head by:
a. Tap water valve or
b. Waterfed pole control
(on/off) valve (e.g. UNGER HiFlo Control).
11. You are ready to start cleaning.
5.3 During operation
1. Periodically inspect the HydroPower®Ultra system during use. Ensure hoses are properly
attached. Inspect system for leaks and proper fit of top cap assembly.
2. Take care when working to ensure there is enough slack in waterfed pole tubing. This
tubing is connected to the top of the unit, and excessive tugging may cause the system to
tip over.
3. Drinking water flows into the system’s lower connection port via tap pressure and flows
upwards through the HydroPower®Ultra vessel. Pure Water exits through the top
connection. When plumbing line pressures fall below 3 bar (44psi),
a reduction in flow rates will be noticeable.
4. Use the included water valve on Water IN valve (8) to regulate the water stream
inside the HydroPower®Ultra.
• After a longer non-usage period, flush the filter thoroughly so that only fresh water is in.

6. Resin Change
6.1 Capacity
Since the HydroPower®Ultra resin filter is used at different water filling points
with various degrees of hardness, the available quantity of completely
desalinated water differs.
The conductivity measurement is used to monitor water quality.
If a conductivity measurement indicates a value of >10 ppm, the resin is
depleted. The Ultra Resin Pack must be replaced.
Raw water quality can be determined in various ways:
a) Information from responsible water works (indication of overall hardness).
b) By measuring the mineral content with UNGER TDS-Meter (5).

6.2 Resin Change - Ultra Resin Pack
REMOVE USED ULTRA RESIN PACKS
1. Close the water line.
2. Close the valve at bottom Water In of the filter (fig. A) and disconnect the hose.
3. Open the valve again, to let the water out of the system (fig. B).
4. Now remove the upper hose.
5. Press yellow FastLock Opening lever (fig. C) to get pressure out of the vessel.
6. Fix the base unit with your feet, press the top cap slightly down and use a
counter-clockwise 1/8 turn to release top cap assembly; remove and set aside
(fig. D).
7. Reach into housing and remove exhausted Ultra Resin Packs(s) by hand with the
rubber handle (fig. E); discard according to local regulations. Be sure that the valve at
the bottom is still open as this simplyfies the removal of the resin packs.
REPLACE ULTRA RESIN PACKS
Install new Ultra Resin Packs by hand (fig. F) – be sure to seat bags with handle
facing up!
One stage unit (DIUH1):
• 1x green Ultra Resin Pack
(never use red Ultra Resin Pack in this unit!)
Three stage unit (DIUH2, DIUH3):
• 1x green Ultra Resin Pack (top position)
2x red Ultra Resin Packs (middle + bottom position)

Resin change
1. Insert the new Ultra Resin Packs with circular movements until they are
completely seated in the tank (fig. F).
CHECK: The green border of the upper resin pack must sit flat on the inner
edge.
2. Stamp the tank on the floor, so that Resin Pack can settle (fig. G)
3. Tap on the green frame to check correct fit. It must no longer wiggle, otherwise
the cover cannot be closed.
The green ring on upper Ultra Resin Pack seals the system, ensuring optimum
resin performance.
Never use other resin in this system! This leads to have water spillage in the
top cap and resin spillage in the hose!
4. Replace the cover. Press it down slightly and then turn it clockwise 1/8
without pressing the yellow lever. Fix the device with your feet.
• If the cover is difficult to rotate, lubricate the sealing ring with silicone grease.
• If the cover does not close, stamp the unit on the floor again and check that
the resin packs are seated correctly.
5. First connect the upper (fig H) and then the lower hose.
6. Turn “ON“ water supply at tap (fig. I).
7. Hold down yellow lever to remove trapped air from system. (Abb. J).
8. Test the TDS value (fig. K) The value should be at 000.

Dynamic Flow Control
Technical Data
6.3 Dynamic Flow Control
The ideal water flow for regular glass cleaning in this system is 120l/hour.
Depending on the regional water pressure it is possible that more water is
produced than consumed.
To make the performance of HydroPower®Ultra independend from incoming
water suppply pressure, the dynamic water flow controller included with the filter
can be used. It reduces the water flow to 2l/minute (= 120l/hour). Optimising the
water flow in this way allows you to use less water, extending the lifetime and
performance of a single resin refill.
You can easily insert the Dynamic Flow Control:
1. Remove the bottom connector. You will need a 30mm and a 19mm wrench
(fig. L).
2. Use the 19mm wrench to hold the front nut and the 30mm wrench to loosen
the rear nut (Fig. M). Loosen the rest by hand and remove the front part of
the connector.
3. Insert the dynamic water flow control into the opening, wide white rim
towards the inside. (Fig.N)
4. Mount the adapter again using the two wrenches. Tighten the two nuts by
hand.
If you want to remove the dynamic water flow regulator proceed in the same way
and push it out from behind in step 3 with a screwdriver carefully. (Fig.O)
Note:
By reducing the flow it will take longer to fill a pure water vessel / storage tank.

Tips for cleaning with pure water
After cleaning I see stains or smudges on the window. What could be causing this ?
How do I clean wooden window frames?
Other sources of errors
The cleaning was not thorough enough:
Make sure to wash off all visible dirt and residues. Rinse thoroughly.
Cleaning detergent residues on the surface:
If the window was previously cleaned using traditional method, it may take up to 2-3 rounds of cleaning
with pure water to achieve perfect results to remove all residues of soap out of the glass.
Insufficient water flow:
An optimum level of between 120-150l per hour is ideal for regular glass cleaning. Make sure that the
entire glass surface has been rinsed thoroughly.
The water is not 100% pure:
Water is considered pure when its TDS measure is 0 ppm - use the TDS meter to check this. The resin
should be changed when the TDS measure rises up to 10ppm to ensure spot-free finish. Consider the
overall quality of incoming water, e.g. well water may contain contaminants that make it unsuitable for
window cleaning.
Wrong movement of the brush:
Always wash and rinse from top to bottom.
Dirt around the frames:
Over time, dirt may accumulate in and around the frames, especially when silicone joints and rubber
seals are not watertight. Water can loosen and transfer the dirt onto glass, so wash and rinse thoroughly.
Damage to laminated and coated glass:
Test on a small area first and allow to dry. Check the results before cleaning the entire glass sur-
face. Water beading on the surface may indicate hydrophobic glass – change to Fan Jets for better
results.
High air pollution:
Dirt particles present in the air, especially in heavy traffic or high pollen count areas, may affect
cleaning results – you may need to dry the window with a squeegee.
Dirty Brush:
Clean the brush to avoid transferring any impurities back onto the window.
Post construction cleaning:
This may require removal of plaster, stucco, concrete, paint, texture, taping mud,
mortar, silicone, stickers and tape from glass. Generally, traditional glass cleaning methods are
recommended for this type of cleaning.
Scratching of Plexi & Acrylic:
Surface dirt retained through static charge can produce scratches in the soft material. Apply
plenty of pure water and use a soft brush such as a boar bristle brush. Contact the client to advise
of the risk of scratching.
Avoid glazed or oiled frames
Pure water dissolves the oils or tannin.
Varnished window frames:
Avoid using pure water as it may accelerate stripping of these coatings.

Quality Tools for Smart Cleaning
CLEANING WITH PURE WATER:
TWICE AS FAST AND SAVING COSTS
NEW!

Quality Tools for Smart Cleaning
PURE WATER - THIS IS
PROFESSIONAL GLASS CLEANING TODAY
Wash, wipe, polish - the three steps to traditional glass cleaning are two too many.
You can also achieve perfect results in just one step - with pure water.
*Prof. Dr. rer.nat. Gerhard Winter, Albstadt-Sigmaringen University, seminar documents February/March 2011
We are now twice as quick as we
were before, thanks to cleaning
with pure water, which means
we can cope with many more
jobs. And the results are top!
Dirk Steinmann, BRAUN Clean-Service
Gebäudereinigungen und Dienstleistungen
Süd-West GmbH
WHAT IS PURE WATER?
It is water in its purest form. Minerals, which would
otherwise leave lime deposits behind on the glass, are
extracted from the water as though with an invisible
magnet. These impurities are known as TDS (dissolved
solids) and measured in ppm (parts per million). Water is
identified as 100 % demineralised (pure) if the TDS value
is 0 ppm.
WHY PURE WATER?
Pure water contains phenomenal cleaning power –
without using any chemicals whatsoever. One-step
cleaning with pure water means there is no need to wipe
and polish the glass. The pane dries streak-free and
without any deposits. It is twice as quick as with
traditional glass cleaning and significantly improves the
cost calculations*.
Using the professional UNGER nLite®systems with
water-fed poles makes pure water the safest method
for cleaning at height – no need for a working platform
or ladders. You save the extra cost of hiring a cherry
picker.
HOW IS PURE WATER CREATED?
The new deionising filter UNGER HydroPower®Ultra
produces 100 % pure water instantly using an
ion exchange process. It removes the minerals from
tap water. The ion exchange resin becomes saturated
with minerals and will need to be changed later. The
lifespan of the resin depends on the hardness of the
water. The softer the water, the longer the resin lasts.

CRYSTAL CLEAR ADVANTAGES
OF CLEANING WITH PURE WATER
SAFE
Safe working from the ground
up to the 6th floor, with no
cherry picker or ladder
whatsoever.
COST-SAVING
Half the labour costs.
