3 Description of the QLEEN DISY E
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 yield 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):
German hardness level Corresponds approximately to
conductance Estimated total quantity Estimated total cleaning

3.4 How the QLEEN DISY E works
Aer plugging in the power plug, the control buttons light up blue and the system is ready for operation.
The operating modes are selected via the control buttons or the remote control.
PUREWATER blue hose, Cleaning solution/tap water black hose, direction change 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 „User information mixed bed resin system“ (Publication of Lehmann KG).
Tap water is required for cleaning with cleaning solution (for particularly heavy soiling). The cleaning solution
is sucked in by the dosing pump from a cleaning solution container 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 and/or Cleaning solution/tap water via a DUO hose attached to the rod 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 rods.
This results in variable working lengths between approx. 2 m (min.) and 21 m (max.).
With the DUO hose, PUREWATER is conveyed in the blue hose and tap water or cleaning solution in the black
hose.
The integrated water quality measuring device provides information on the quality of the incoming tap water
and the outgoing PUREWATER.
3.5 Areas of application
Typical applications for the QLEEN DISY E are:
• To restore and increase the energy yield of solar and photovoltaic systems.

Caution Risk of injury
• Tripping hazard: Pay attention to the hose when working!
• Crash hazard: Place the poles on the floor during work interruptions! Do not lean against
vertical walls, this may cause them to fall over and result in injury or damage to the
equipment!
• Crash hazard: Do not work with the pole system above wind force 2 (>3,3 m/s)
• Risk of electric shock: Do not work with the pole system under high-voltage lines!
For most soiling, the PUREWATER is completely suicient.
Only heavily soiled and oily or greasy surfaces must be pre-treated with a cleaning solution.
Dirt that can only be removed by intensive mechanical cleaning (e.g. glass plane) should also be pre-treated
accordingly.
The higher the level at which work is carried out, the greater the dirt load at the lower levels, because the
"foreign dirt" from the higher level is added to the "inherent dirt".
This should be taken into account when calculating the work and the order.
1. Mount the pole system to the maximum height of the cleaning area,
see Page 16 (4.11 Mounting the rods and brush)
2. Position the brush in the upper area and activate the desired cleaning mode with the remote control
3. Move the brush from one side to the other with even up and down movements over the surface to be
cleaned
4. To increase the mechanical cleaning power, press the pole system lightly against the surface to be
cleaned with the help of the guide hand
5. Proceed in the same way for the surfaces below until the entire surface has been cleaned
6. Adjust the pole system according to the working height to ensure fatigue-free work

20 |
For cleaning solution operation, the dosing pump must first be bled, see Page 15 (4.10 Bleeding
the dosing pump).
When using cleaning solution, observe the respective specifications and safety instructions of
the manufacturer.
5.1 Cleaning with PUREWATER
5.2 Cleaning with tap water and cleaning solution
In the case of heavy soiling, it is cheaper and more eective to pre-clean with tap water first.
The dosing pump mixes the aspirated cleaning solution with the tap water.
The dosing pump has an adjustable flow rate of 1 to 6 liters per hour.
In the case of the Vario brush bow, approximately 200 liters per hour flow through the nozzles, which
corresponds to an adjustable mixing ratio of 1:200 to 1:33.
It is possible to change the cleaning mode at any time using the control buttons and the remote control.
For example, aer cleaning with cleaning solution, the hose can be rinsed or the area to be cleaned can be
rinsed with tap water.
The tap water or the cleaning solution is pumped through the black hose.
Cleaning with PUREWATER is the most chemical-free and sustainable way of cleaning.
Surfaces dry streak-free and without wiping due to the good salt absorption capacity of the PUREWATER.
The PUREWATER is pumped through the blue hose.
