User information mix-bed resin system (handling, replace-
ment, recycling, disposal)
We are delighted that you have decided for a Lehmann mix-bed resin system. Before
you start to work with demineralized water (pure water), we would like to provide you
with some important user and safety information. We kindly ask you to read them
carefully and to essentially comply with. As owner and operator of a Lehmann
cleaning system also make sure that your sta has read this “User information
mix-bed resin”, too, and observes the safety and warning information.
Furthermore, we kindly ask you to consider and observe the General User and Safety
information (see Lehmann publication “General User and Safety Information”).
The document on hand is the original user information. It was written in German
language. Versions in other languages are translations of this original user informa-
tion.

1. Description of the PURAQLEEN
procedure (Cleaning with demineralized
water)
The high chemical-free cleaning power of pure water is the principle the Lehmann
PURAQLEEN procedure for glass and façade cleaning is based on. Tap water is conduc-
ted through a mix-bed resin system there (granulate bottle). The minerals contained in
tap water adhere to the granulate (mix-bed resin). The tap water is demineralized and
fed to the pump as pure water and to the cleaning head aerwards. Pure water has
not only excellent wetting capacities, but also dries without leaving stains and streaks
even in strongest sunlight. Thus, a use of detergents can be omitted in many cases
(exception: greasy, oily or very heavy pollutions).

1.2 Safety remark
Pure water (= demineralized water) freezes – dierent from tap water – already
at +1°C. Thus, no cleaning works with demineralized water are allowed at outside
air temperatures below +3 °C. The demineralization station and the mix-bed resin
must be protected against temperatures below +1 °C and frost, because frost may
damage the water-conducting parts of the cleaning system. Mix-bed resin must be
stored frost-free and must be used only for cleaning works up to +50 °C maximum.

2. Handling mix-bed resin
Lehmann cleaning systems are delivered with full granulate bottle. The granulate
bottle is immediately ready for use. The following table displays the amount of pure
water that can be produced (in 1, right column) with one granulate bottle lling
depending on the water’s electrical conductivity (in μS; le column):
3. Replacing the mix-bed resin
The mix-bed resin must always be replaced
• if the device measuring the water conductivity displays a value higher than
„050“ (μS).
If the measuring device displays a value higher than „010“ (μS), the granulate is
about 80% saturated and has to be replaced as soon as possible. It has to be taken
into account that the measuring value does not increase linearly but exponentially. A
working pressure of 5 bar applies to the water conducting system. Due to this, the
pressure must be removed from the granulate before replacement.
New granulate can be ordered in 25-litre-sacks (accessories), either as new granula-
te or as recycled granulate. The 25-litre-sacks must be stored in a suitable room. The
room must be well ventilated, dry and frost-free and have a clean and even ground
with suicient load-bearing capacity. Recycled granulate has an about 80% produc-
tivity compared to new granulate. To have the system ready for operation at any
time, it is recommended to permanently have at least one granulate bottle in reserve
(accessory).
Procedure
CAUTION
Electrical Shock Hazard! The live system and accessory parts and plugs must not be
touched with wet hands. Protective gloves must be worn.
1. Disconnect the system from power supply*
▷ Unplug the main plug
✓ The system is disconnected from the power supply.
2. Remove the system pressure
▷ Open all levers at the system and put them into position „open“ to do so
✓ The system ist pressureless.
3. Shut o the water supply and disconnect the hose connection at the quick faste-
ner at the granulate bottle top
✓ The water supply is shut o and the quick fastener is disconnected.
4. Disassemble saturated granulate bottles
▷ Put granulate bottle into upright position
▷ Cautiously li down the granulate bottle from the system trolley
• The granulate bottle weighs about 30 kg in this status!

CAUTION
Risk of crushing! Feed might get jammed by the granulate bottle.
• Wear safety shoes!
• Set o the granulate bottle on even ground with suicient load-bearing ca-
pacity only
▷ Put the granulate bottle on the ground in upright position and protect it against
tipping over
5. Return saturated granulate bottles to the Lehmann KG (Option 1 – this service is
currently oered for Germany only)
▷ Cautiously disassemble bottle top with hose and lter
▷ Cautiously put the granulate bottle into tilted position
▷ Drain surplus water – hold possibly escaping granulate with a sieve or with your
hand
▷ Close the granulate bottle carefully with the screw cap
▷ Check the screw cap for tightness
▷ Send the saturated granulate bottle back to the Lehmann KG with return note
• The granulate bottle must be closed absolutely secure/tight. No water must
escape during transportation!
✓ The granulate bottle is prepared for sending.
6. Replace saturated granulate yourself (Option 2)
▷ Cautiously disassemble the bottle top with hose and lter
▷ Cautiously bring the granulate bottle into tilted position and remove the granulate-
water-mix from the granulate bottle
▷ Cautiously bring the granulate bottle in tilted position over a collection tank (about
30 l volume)
▷ Pour out the granulate-water-mix quickly
▷ Rinse and ush granulate remains with water
▷ Strain o the collection tank cautiously
▷ Hold back the granulate with a sieve or by hand
▷ Dispose the drained granulate into the household waste or, within Germany, by
sending it back for recycling (see 4, please, Recycling or Disposal)
CAUTION
Risk of crushing! Feed might get jammed by the granulate bottle.
• Wear safety shoes!
• Set o the granulate bottle on even ground with suicient load-bearing ca-
pacity only
▷ Protect the granulate bottle against tipping over
▷ Cautiously ll in new granulate
• Use a suiciently big funnel as lling aid here
• A bottle lling needs a 25-litre-sack of granulate
▷ In case the granulate bottle is not immediately recommissioned again: Close the
granulate bottle with the screw cap
✓ The granulate was replaced
7. Assemble the granulate bottle
▷ Unfasten the screw cap from the new granulate bottle
▷ Slowly and cautiously ll the granulate bottle with water until the granulate is las-
tingly covered by water

• The process will take a few minutes because the granulate soaks with water
only slowly
> Check if the position of the riser pipe in the granulate bottle head is correct
• The riser pipe must be pressed ush and up to the stop into the granulate
bottle head and t closely at the sides
• In case of leakages at the riser pipe tap and pure water will mix which can
result into a reduced cleaning performance.
▷ Rinse the granulate bottle top, the riser pipe fastened to it included, with cautious
but quick upward and downward movements into the granulate
▷ Clean the thread at the granulate bottle head from granulate remains
▷ Fasten den granulate bottle head by screwing into clockwise direction
✓ The granulate bottle is screwed together.
8. Assemble granulate bottle
▷ Li the granulate bottle cautiously into the system
• The granulate bottle weighs about 30 kg in this status!
▷ Connect the two hoses at the granulate bottle top with the two quick fasteners (IN,
OUT) with the granulate bottle top.
▷ Fasten the front lid again
✓ The granulate bottle is assembled
4. Recycling or Disposal
You have the following options for recycling or disposing the saturated granulate:
1. Return the saturated granulate bottle to Lehmann KG for exchange. This exchange
service is oered inside Germany only:
• The return to Lehmann KG is done via a return note that is enclosed to the
granulate bottle. The saturated granulate is recycled at the Lehmann KG.
2. Replace the saturated granulate yourself and return it to Lehmann KG for proces-
sing:
• Loose saturate granulate can – properly packed – send back to the Lehmann
KG. The shipping costs are paid by the sender.
3. Replace the saturated granulate yourself and dispose it as household waste:
• The granulate is environmentally neutral and can be disposed as household
waste.
• Still, we kindly ask you to consider possible information provided by your
regional disposal service company.
5. Accessories
The Lehmann KG oers a wide range of accessories and spare parts. In case of
interest we will be pleased to send you the current overview. Just send a request
