2 General notes and safety instructions
This manual will give you an overview of the functions, operation and proper use of our QLEEN PROFI I
machine.
Certain symbols in these instructions indicate various information:
The information sign indicates useful tips and information.
The exclamation mark warns of potential dangers and risks
2.1 Instruction structure

6 | General notes and safety instructions
2.2 Safety instructions
Warning: Fire and explosion hazard:
• Never use flammable liquids or operate the machine near flammable liquids/vapors or
combustible dust.
This machine is not equipped with an explosion-proof motor. The electric motor emits sparks
during startup and operation that can cause ignition of flammable materials.
• Do not aspirate flammable materials with the machine.
Warning: Risk of electric shock:
• Before each start-up, check the power cable and the power plug for damage.
If any damage is detected, the machine must be shut down immediately and repaired by a
specialist!
• When plugging in the machine, make sure that the power plug and your hands are not wet!
Caution: Danger of accident:
• The operating personnel must be adequately trained in the use of the machine.
• The machine must be in perfect condition.
• Only set up the machine on solid, even surfaces.
• Wear sturdy, non-slip footwear with protective caps to protect yourself from being crushed by
the machine.
• Work on roofs only with appropriate safety equipment.
• Take care not to get mixed bed resin in your eyes. For further safety instructions and handling
of the mixed bed resin, read the "Mixed bed resin systems user information".
• When using cleaning solution, observe the respective manufacturer's specifications.
Warning: Risk of accidents and damage to the machine and equipment
• Use the machine only from +5 °C and higher, frost damage to the machine and equipment may
occur.
• Do not work with the pole system in wind forces above 2 (>3.3 m/s), the rod system may
buckle and fall o

3 Description of the QLEEN PROFI I
3.1 The PUREWATER principle - cleaning with pure water
The high chemical-free cleaning power of PUREWATER is the basis on which the
PURAQLEEN principle for cleaning glass, solar and facade surfaces.
In this process, tap water is passed through a granulate bottle. The minerals contained in the tap water
accumulate in the mixed bed resin and all salts are removed from the water.
The tap water is demineralized by pre-pressurization in the granulate bottle and reaches the cleaning head as
PUREWATER.
PUREWATER not only has a very good wetting capacity, but also dries without stains or streaks, even in strong
sunlight.
This means that in many cases the use of cleaning solutions can be dispensed with.
(exception: greasy, oily or very heavy soiling).
3.2 Sustainability
Our system contributes to the careful and sustainable use of resources for cleaning in times of dwindling resources.
In contrast to the reverse osmosis process, our devices operate in the energy-saving low-pressure range; the
pressure of the domestic water supply is suicient to operate our devices.
In addition, our systems convert 100% of the supplied water into PUREWATER, which can be used for cleaning.
3.3 Water hardness and productivity of the mixed bed resin
The water hardness at the place of use can be obtained from the local water supplier.
This allows you to estimate the yield of the granulate bottle.
Depending on the measured value, the following values result for the maximum PUREWATER quantity and
cleaning time with a granulate bottle (at a maximum initial value of 50 µS, approximate data):

3.4 Functionality of the QLEEN PROFI I
Aer switching on, the power button lights up green and the system is ready for operation.
The operating modes are selected via the control buttons or the remote control.
PUREWATER/line water blue hose, cleaning solution/line water black hose, change of direction ROTAQLEEN
Tap water is required for cleaning with PUREWATER.
For this purpose, tap water is passed through the mixed bed resin system in the granulate bottle and
demineralized in the process.
See also "Mixed bed resin system user information" (Lehmann KG publication).
Tap water is required for cleaning with cleaning solution (for particularly heavy soiling). The cleaning solution
is sucked out of a cleaning solution container by the dosing pump and added to the tap water in the dosage to
be set.
Aer working with cleaning solutions, the system should always be rinsed with tap water.
A pump conveys the clean water/cleaning solution/line water via a DUO hose attached to the pole set* to the
cleaning head* at the top end of the pole set*.
There it is distributed evenly and sparingly over the surfaces to be cleaned via fine nozzles*.
The pole set* consists of individual, mountable poles.
This results in variable working lengths between approx. 2 m (min.) and up to 21 m (max.).
With the DUO hose, the blue hose conveys the PUREWATER or tap water, and the black hose conveys the tap
water or cleaning solution.
The integrated water quality measuring device provides information on the quality of the outgoing PUREWATER.
3.5 Areas of application
Typical applications for the QLEEN PROFI I are:
• To restore and increase the energy yield of solar and photovoltaic systems.
• Glass-clear and streak-free view for windows, window frames, conservatories, glass and greenhouses
• Oen diicult to access outdoor advertising spaces and lighting boxes
• Against the intensive pollution by insects on vehicles (train, ship, plane, truck, car).
* Only included in the variant QLEEN PROFI I complete set (70042)
