3 Description of the QLEEN Q-Station
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):
* Based on a flow rate of 200 l/h with the brush bow Vario

3.4 Functionality of the QLEEN Q-Station
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/tap water blue hose, cleaning solution/tap 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/tap 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 Q-Station 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).

4.10 Mounting the poles and brush*
Starting up
The pole system supplied is for a height up to 15 m and can be extended to a height of 21 m.
The carbon poles should always be at the top and the titanium poles below them because of weight and
stability.
To protect against damage to edges and protrusions, the half titanium poles must always be mounted in the
uppermost position.
1. Place the brush adapter on the half titanium pole and fasten it with a clockwise rotation
2. Secure with the wing screw
Caution: Danger of falling:
• Always secure the poles and brush adapter with the wing screws
• Always use half the titanium rod as the top pole to protect the carbon poles from damage
• Do not use pole set above wind force 2 (>3.3 m/s)
3. Insert the brush bow into the brush adapter until the snap button engages
4. Loosen the knurled screw on the joint and set the desired working angle of the brush
5. To set the brush vertically, press the snap button and rotate the brush holder 90 degrees
180°
* Accessories are not included

| 17
6. Connect the blue hose with the 2 nozzles through or over the brush
7. Connect the black hose to the single chemistry nozzle or the 2 free nozzles
8. Fix the DUO hose with the Velcro tape
9. Place the brush against the wall and push it upwards
10. Click in the next bars from below and fix them with a half
clockwise rotation of the bar
11. Secure with the wing screw
12. Secure the hose to the pole with the Velcro strap
13. Add more poles up to the required height by repeating steps

Cleaning
5 Cleaning
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 poles and brush)
2. Place the brush in the upper area and activate the desired cleaning mode with the remote control
3. Move from one side to the other with even up and down movements over the surface to be cleaned
4. To increase the mechanical cleaning performance, 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 underlying surfaces until the entire surface is cleaned.
6. Adjust the pole system according to the working height to ensure fatigue-free work
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!

5.1 Cleaning with PUREWATER or tap water
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 PUREWATER.
The cleaning mode tap water is the cost eective way to pre-clean heavily soiled surfaces.
The cleaning mode is changed with the control button and/or the remote control.
The PUREWATER or tap water is pumped through the blue hose.
