Description of the QLEEN PURASTART E
3 Description of the QLEEN PURASTART 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 and solar 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 how productive the granulate bottle is.
Depending on the measured value, the following values result for the maximum PUREWATER quantity and
cleaning time with one granulate bottle (with 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 PURASTART E works
Aer switching on, the power button lights up green and the system is ready for operation.
The operating mode is selected via the remote control.
PUREWATER, 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.
A pump transports the clean water via a hose attached to the telescopic pole* to the cleaning head* at the
upper end of the pole set*.
There it is distributed evenly and sparingly over the surfaces to be cleaned via fine nozzles*.
The telescopic CARBONPOLE* is made of a stable and light carbon material.
When retracted, it has a length of 2.04 m and can be extended to a length of 9.00 m. This results in variable
working lengths.
This results in variable working lengths between 3 m (minimum) and approximately 10 m (maximum).
The hose is 25 m long and made of a robust material.
The integrated water quality measuring device informs about the quality of the outgoing PUREWATER.
3.5 Areas of application
Typical applications for the QLEEN PURASTART E are:
• To restore and increase the energy yield of small 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).

Starting up
Water can be supplied directly to the house water connection via a Gardena hose or through a tank with the
suction hose.
Caution the device may be damaged:
Only use clean tap water with a maximum inlet pressure of 15 bar for the water supply!
It can otherwise lead to damage to the device.
4.2 Connection of the water supply
Before assembly, check the strainer and the seals in the quick coupling for contamination.
These can reduce the flow rate and lead to a drop in pressure at the nozzles, see
Page 21 (8.4 Cleaning/replacing the strainer at the water inlet)
4.3 Water supply through the house water connection
2. Connect the house water connection by means of Gardena
hose to the input of the QLEEN PURASTART E
3. Open the tap of the house water connection
⇒The water supply via the house water connection is
established
1. Attach the Gardena adapter to the water inlet and lock it in
place by turning it clockwise.
• Before connecting the tap water, make sure that the shut-o
tap is closed.

4.7 Connecting a ROTAQLEEN*
The ROTAQLEEN are electric rotating brushes for use with heavy soiling and/or large areas.
The QLEEN PROFI I is equipped with a connection and control for supply and return for all current
ROTAQLEEN
For further information read the „User information ROTAQLEEN“.
Beware of damage to the ROTAQLEEN:
• Always connect the blue input to the ROTAQLEEN and run water through it during operation,
this serves to cool the motor.
• Do not use a cleaning solution with the ROTAQLEEN
1. Insert the ROTAQLEEN into the brush adapter until the snap button clicks into place.
2. Roll out the cable to the required length
3. Connect the socket of the cable drum with the plug of the ROTAQLEEN

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. Set the shut-o tap to the "ON" position
2. Extend the telescopic rod to the maximum height of the cleaning surface
3. Place the brush in the upper area and activate the machine with the remote control
4. Move from one side to the other with even up and down movements over the surface to be cleaned
5. To increase the mechanical cleaning power, press the telescopic rod lightly against the surface to be
cleaned with the help of the guide hand
6. Proceed in the same way for the underlying surfaces until the entire surface is cleaned.
7. Adjust the telescopic rod 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!

With the integrated measuring device you can monitor the quality of the filtered water at any time.
We recommend for glass and solar systems from a value of 50 µS to replace the mixed bed resin.
If the values are above 50 µS it can not be guaranteed that the surface dries streak and stain free.
6.1. Operation
• Switch on the measuring device with the power button, aer 10 minutes the device switches o
automatically
